Top Weighting Arms for Short- and Long-Staple

Ring Spinning Frames

and Short-Staple Roving Frames

By Wolfgang Lehner, SUESSEN Technical Department

Fig. 1

Fig. 2 Fig. 3

HP Top Weighting Arms (Fig. )

HP Top Weighting Arms with partial

weight release mechanism permit

reducing the pressure on the top rol-

lers in such a way, that grooving of the

cots over holiday standstills is

avoided. The top arms are for single-

handed operation. The top roller

retainers fit tightly into the top arm

body.

Top rollers are held strictly parallel

and in perfect alignment with bottom

rollers. Top roller setting can be

adjusted with the top arms in their

loaded position. This permits most

accurate roller settings.

Opening and closing the top arms

does not affect the top roller position

with regard to the yarn path. This is of

significant advantage to CoreYarn

spinners.

Top roller retainer (Fig. 3)

The heavy-duty plate springs apply

their constant pressure to the top rol-

lers directly and totally frictionless. Top

and bottom roller alignment is ensured

by machining the weighting units after

the assembly of the top weighting arms,

just as they are installed in the ring

spinning frame (Fig. 2). Precise machin-

ing and the extra-wide support of the

top rollers ensure perfect alignment

and therefore uniform top roller load.

Supports are available for various top

roller types (manufacturers others

than SUESSEN).

Depending on the design, the load of

weighting units can be set in up to 3

steps.

SPINNOVATION No. 8

Heavy-duty plate spring (Fig. 4)

The heavy-duty plate spring, hardened

and with special coating, serves simul-

taneously as guiding element. As a

result, fewer movable components are

required and friction is reduced, com-

pared with other designs. The compu-

ter-optimized leaf spring design pre-

vents side forces on the top rollers.

Conventional units loaded by a flat coil

tend to evade laterally, so that top rol-

lers take an oblique position. The rea-

son is that the ends of flat coils are

never 00% parallel and bow laterally

when loaded in the centre.

Pneumatically loaded systems usually

are equipped with loading elements

subject to friction. Due to the hyster-

esis effect of such systems, the load

varies to a more or less great extent.

The advantage of central load relief is

compensated by a restricted reliability.

Today’s spinning mills being in opera-

tion 24 hours a day and 2 months a

year, central load relief is no longer a

significant advantage.

HP-Cradle (Fig. 5)

The ”SUESSEN High Stability Princi-

ple” method of loading the top apron

cradles provides highest stability and

holds the front edges of the cradles

safely down. It guarantees constant

cradle nip pressure all the time. The

cradles are further equipped with spe-

cial anti-friction clips at their front

edges. The anti-friction clips are made

of an extremely wear-resistant plastic

material and can be replaced if requi-

red. This is very cost-efficient, because

only the clips need to be replaced

in case of necessity, and not the

whole cradle. High-stability cradles in

combination with anti-friction clips

(see Fig. 9) ensure perfect running of

top aprons. As a result, aprons run

smoothly and without buckling even at

narrow settings of the apron nip, which

are favoured for better fibre control in

the main drafting zone. The HP-Top

Weighting Arm Family today has the

following members:

HP-A 30/320

for short-staple fibres up to 60 mm

HP-A 40

for short-staple roving frames

Experience with SQ Modernization

on Autocoro Rotor Spinning Machines

By Mike Basting

Since the development, design and

first presentation of the Quality Moder-

nization Concept in 999, SUESSEN

has converted almost 00 Autocoro

Machines world-wide.

Today, SUESSEN offers different

SQ Modernization Packages for the

SpinBoxes SE 7, SE 8, SE 9 and SE 0.

. Customer Benefit

Modernized machines generally show

π improved yarn quality

π reduced ends-down rate

π increased machine output

π reduced maintenance and clean-

ing costs

π lower energy consumption per kg

yarn

Short pay-back periods are ensured

by calculations of profitability, establi-

shed in co-operation with some of our

customers. Regular periods are bet-

ween 0.5 and 2 years depending on

yarn count, raw material and the local

cost structure. See chart for values in

industrial production.

2.5 Spinning of man-made fibres

For all modernization packages, spe-

cial opening roller housings are avail-

able for processing polyester fibres

and blends. Together with the spinning

components Mima-nozzle and open-

ing roller S 43 trouble-free spinning of

man-made fibres at high rotor speeds

is no problem any more.

Apart from the scope of delivery of the

different SQ packages a number of

options are available for each pack-

age, so that every customer receives

the optimum modernization package

for his special requirement and appli-

cation.

3. Some Special Technical Features

of SQ Modernization Packages

3. Adjustable BYPASS

The adjustable BYPASS allows higher

air velocity in fibre channel and lower

air velocity in trash extraction chute.

This reduces ”merry-go-round” fibres,

i.e. fewer yarn faults, reduces ”dolphin

jumps”, i.e. less dirt in the yarn, and

reduces extraction of good fibres, i.e.

better usage of cotton. The BYPASS

permits accurate setting of extracted

trash percentage and keeps rotor

groove clean over a longer period.

Ends-down are reduced as well as

imperfections and clearer cuts, where-

as yarn quality and spinning stability

are improved.

3.2 Fixed fibre beard support

for better combing of sliver

Contrary to movable feed tables, the

fixed fibre beard support does not fol-

low the minute variations in sliver

thickness. The combing distance (see

”a” in Fig. 2) is constant with fixed fibre

beard support, hence accurate guid-

ance and subtle intensive combing

of fibre beard is ensured. Further the

combing conditions right up to

fibre beard edges are constant at all

spinning positions.Yarn quality is

improved, in particular evenness.

opening roller teeth profile and impro-

ves considerably the trash extraction.

Air turbulence at the opening roller

rims is eliminated with the effect of a

better cleaning performance.

3.3.2 Labyrinth air seal of opening

roller

The aerodynamic labyrinth seal of

opening roller improves air balance

and prevents disturbance of spinning

process due to air leakage. Dirt and fly

collecting behind the opening roller

cover plate is a matter of the past.

3.4 TwinDisc with 2 cooling grooves

2 cooling grooves reduce the heat on

the TwinDiscs at highest rotor speeds

and increase the operating life sub-

stantially.

3.5 EC-Bearing

The EC-Bearing is a maintenance-free

axial bearing for rotors with proven

ball support located in an exchange-

able grease cartridge, to assure opti-

mum lubricant usage and accurate

axial support of rotor. The SpinBox

contamination is minimized. There is

no additional energy consumption,

as is the case with e.g. magnetic

bearings.

3.6 SpeedPass and Swan-Neck

These are features for the special

SpinBox designed for man-made

fibres and blends.With the SpeedPass

the level of suction at the fibre-chan-

nel is increased and ensures better

straightening of the fibres during their

conveyance to the rotor. The ”Swan-

Neck”, an additional cavity in opening

roller housing, facilitates the removal

of fibres from the opening-roller. It

works like an air foil (airplane wing): A

radial pressure gradient is created,

which helps to lift the fibres off the

teeth of the Solidring. It guarantees a

safe removal of delicate fibres from

the opening-roller.

3.7 CFK Yarn Guide Rod

The carbon fibre rod is 5 times lighter

than steel, but with equal stability cha-

racteristics, tube-shaped without any

mass-increasing cover. One piece is

as long as one spinning section, the

pieces are connected by couplings.

The yarn guides are clamped onto the

rod. The rod is guided by special plain

bearings fastened at every spinning

head (see report in SPINNOVATION

No. 7).

3.8 SweepCat

The extracted trash from the sliver falls

out from the housing through the

extraction chute into a wide trough,

placed lower than the usual conveyor

belt underneath the SpinBoxes.

Hence, already extracted trash parti-

cles are no longer sucked back into

the SpinBoxes. This causes fewer

machine stoppages as the SpinBox is

not contaminated any more, longer

manual cleaning intervals are possible

and machine efficiency is increased.

Yarn faults, clearer cuts and ends-

down are reduced.

Summary

Modernized rotor spinning machines

have a great benefit for the spinning

mill due to better yarn quality and

higher machine efficiency. Generally

the pay-back periods are very short.

SPINNOVATION No. 8

Capacity of Work

By Peter Stahlecker, MD SUESSEN

This term has been around for quite

some time, but some of our customers

do not have a very clear understand-

ing, what this term means.

This article should shed some light on

this value.

. The physical dimension is given by

[cN*cm], that is Force x Length. ()

This gives us a hint: It is the product of

breaking force of the yarn, multiplied

with the breaking elongation of the

yarn.

The higher this value, the better the

yarn will perform in warping and

weaving.

We can visualize it as follows:

π Assume, the yarn was a steel wire:

Obviously, the break force is very

high, elongation very low, and this

”yarn” would not break much dur-

ing weaving.

π Now, assume the yarn was extre-

mely elastic like Lycra: The break

force is very low, elongation very

high, and this ”yarn” would not

break often during weaving, too.

These two extreme cases show, that

the product of elongation and break

force is a suitable indicator of weaving

performance. The higher the value, the

better the weaving performance one

may expect.

2. In a formal way, the Capacity of Work

is defined as follows:

Yarn breakage

CW = ∫ F(E)dE (2)

0

Here, E means Elongation in cm (NOT

in %). F(E) means the Force, that has

to be applied to the yarn to extend it

from its original length L0 to the length

L0 + E. USTER has taken L0 = 50 cm,

presumably, because that is the length

of yarn clamped in the USTER Tensor

Jet (F(E) in engineering or physics is

sometimes called a stress/strain

curve, here the term strain/stress

would be more appropriate).

For those customers, who do not have

an USTER equipped to give this value,

an approximation may be calculated

as follows:

CW = Breakforce x Elongation (3)

[in %] x 50 / 2 [cN*cm]

This formula assumes a strictly linear

relationship between Force and Elon-

gation (F(E) = const * E) and I have

found it to be accurate within better

than 0%.

Summary:

Capacity of Work is a useful value to

indicate the performance of yarn in

weaving.

As EliTeQYarn generally has better

strength and better elongation than

conventional ring spun yarn, its

Capacity of Work is much higher than

that of conventional yarn. This,

together with the low hairiness

explains the vastly better performance

of EliTeQYarn in weaving.

Ring and Ring Traveller Systems

for Compact Yarns

By Franz Oberholzer, Head Research Rings and Travellers, Bräcker AG, Switzerland

Introduction

The new compact spinning systems

EliTe and ComforSpinQ produce yarns

which place new demands on the ring

and ring traveller system. Compact

yarns are distinguished by a particu-

larly smooth surface with hardly any

disturbing elements. Since all the

fibres are firmly embedded in the body

of the yarn, they are subject to much

less abrasion at the deflection points

so that virtually no processing errors

occur. The space required by the yarn

in the yarn thread passage is reduced

to a minimum.

However, this extremely low degree of

hairiness results in under-lubrication

of the open friction system and that, in

turn, places special demands on the

rings and travellers.

Obviously, the performance of rings

and ring/traveller systems is influen-

ced by other factors. This article pri-

marily analyses the lack of lubrication

and its repercussions on the rings and

travellers.

Function of the ring and traveller

To give you an overall impression, let

us recapitulate the most important

features of the ring and traveller:

π The ring traveller system is a brak-

ing system (creates the yarn ten-

sion)

π The ring and ring traveller system

is lubricated by fibre elements, wax

and other particles (fibre film). This

coating must regenerate itself con-

tinuously. If the fibre film is stripped

away, metal contact between the

ring and traveller is the result.

π The friction (friction coefficient)

depends on a variety of parame-

ters such as fibre type, lubricant

content of the fibres, ring and trav-

eller surface, shape and profile of

the traveller etc.

Requirements of the ring surface

As a result of the lack of lubrication

produced by compact yarns, the trav-

eller running surface on the ring is

subject to considerable friction. If no

lubricating film exists, temperatures of

over 800Ω C occur in the contact area

of the traveller/ring.With conventional

ring surfaces, small particles of travel-

ler material are welded onto the ring.

This process is referred to as micro

welding. It leads to premature wear of

the ring and results in erratic traveller

operation, differences in yarn tension

and a reduction in yarn quality. For

compact yarns it is therefore very

important that rings with an excellent

wear-resistance are used.

Ring surface destroyed as a result of

micro welding

Titan ring surface displays no micro

welding

Flange shapes

Compact yarns are mostly produced

in finer yarn counts. The flange pro-

file and the inclined flange profile

Orbit are preferred, as they proved to

be successful for conventional ring

yarns.

Bräcker rings and travellers for the

successful processing of compact

yarns

Rings

Bräcker Titan rings satisfy the require-

ments in terms of resistance to wear

and ensure that traveller material is

not welded onto the ring. As a result,

constant yarn quality can be produced

from spindle to spindle and machine

to machine.

Titan ring

The operating life of a Titan ring is

extremely long so that an optimum

yarn quality is guaranteed over a con-

siderable time.

Operating life of Titan rings

The flange shape Fl A98 is the stand-

ard design installed in the SUESSEN

EliTeQCompactSet and can be used

universally for the entire yarn count

range both for normal and high perfor-

mance use.

Orbit rings are suitable for the high

performance domain and are used

exclusively on Rieter K40 and K44

machines.Yarns coarser than Ne 30

and finer than Ne 80 are also spun on

Rieter K-machines preferably on

flange rings.

Travellers

In order to make best use of the redu-

ced fibre lubrication, travellers offering

a deeper thread passage must be

used. Due to the compactness of the

yarns, however, no negative repercus-

sions such as production neps occur.

Moreover, for cotton yarns, a broad

half-round profile (udr) is preferred,

while for blends and special yarns a

normal half-round profile (dr) is desir-

able.

C EL udr and SFB 2.8 RL dr are the

travellers used most for spinning

compact yarns. Nevertheless, the

specific performance parameters and

customer wishes are to be taken into

account.

Rosink Cot Grinder now also for the EliTop

By Udo Stentenbach, Managing Director Rosink, Germany

Rosink GmbH + Co. Maschinenfabrik,

Nordhorn Germany, successful in

design and development of textile

machines for spinning mills for the last

55 years, has taken over the complete

product line of ECC GmbH, former

Wolters-Platt GmbH.

Over the last years, the machines

belonging to the so-called ”service

machines for the cylinder workshop”

have been manufactured by Rosink.

Since technical documentation and

files as well as the complete stocks

are also part of the take-over, Rosink

can guarantee a very good after-sales

service to all users of the former Wol-

ters machines.

Since March 2002, the whole Wolters-

range of service machines for the

cylinder workshop and the flat cloth-

ing workshop, as well as all the service

machines for the carding machines

are developed and manufactured

under the name of Rosink.

The modernity of Rosink allows the

permanent development of the former

”Wolters” machines.

The combination of the different pro-

duct lines of Rosink, i.e. can coilers,

drafting units, special machines and

stainless steel cylinders with the Ser-

vice Machines gives Rosink a larger

position world-wide and the possibility

of being closer to the market in order

to provide a better service to their cus-

tomers.

In cooperation with Spindelfabrik

Suessen, Rosink has developed a tool,

which can be easily mounted on the

manual side of the SZ or the SZ M

cot grinder and allows to buff com-

plete EliTops in only one step.

It is no longer necessary to dismantle

the EliTop in order to buff the different

cots one by one.

Once the cot grinder has been

adapted to the EliTop you are using,

you just need to place the other ones

in the machine to grind them as required. Both top roller

pairs are buffed exactly to the pre-selected diameter, so

that the required tension draft (diameter relation) keeps

constant.

The obtained micro-inch finish, concentricity and diameter

tolerances meet with the instructions and recommendations

of Spindelfabrik Suessen. It is possible to grind the EliTops

up to 8 times with a pre-selected diameter reduction of 0.3

mm.When using two tools on one machine, it is possible to

grind two EliTops at the same time.

It is very easy and simple to adapt the special tool to the

Rosink cot grinder.

Of course you still have the possibility of grinding manually

any other cot with a diameter between 24 and 80 mm and a

maximum length of 400 mm on the machine.

At the moment Rosink is developing a system in order to

grind the complete EliTops automatically, what would of

course facilitate and accelerate the buffing of EliTops.

This is already possible, when the EliTops are dismantled.

Textil Bezerra de Menezes S.A., Brazil

Interview with Mr. Ivan Bezerra Filho, Vice President

by Fred Mägerle, SUESSEN, Area Sales Manager

Fig. : Mr. Ivan Bezerra Filho,Vice President TBM

In 200, TBM purchased from

SUESSEN 24 Fiomax E EliTeQCom-

pact Ring Spinning Machines. Each

machine is equipped with 200 spin-

dles.

SPINNOVATION: Mr. Bezerra, please

be so kind as to you give us a brief

summary of the history of TBM.

Mr. Bezerra: The beginning of textile

business was with the cotton mill in

the 950s. In 975 we decided to verti-

calize and so the first spinning mill

was born, which finally started its ope-

ration in June 980.

In 984 the Textil Bezerra de Menezes

S/A amplified and started the second

unit in August 988.

The year 2000 was marked by the

acquisition of a spinning mill in

Caruaru City in the state of Pernam-

buco, amplifying our productivity

range.

In 2002 we inaugurated another spin-

ning mill, using an innovative spinning

technology: Compact yarns in 00%

cotton. This unit is situated in Maraca-

nau, the state of Ceara.

SPINNOVATION: Why did TBM pur-

chase the EliTeQSpinning System?

Mr. Bezerra: Our objective was (and is)

to spin a yarn which maintains its cha-

racteristics in comfort, humidity

absorption and touch, coming at the

same time very close to a continuous

filament yarn concerning regularity,

brightness of the colours and lustre.

SPINNOVATION: What are the main

benefits for TBM as a compact yarn

manufacturer?

Mr. Bezerra: The greatest benefit is giv-

ing our clients the possibility of offer-

ing a new product with different appli-

cations, becoming more competitive

abroad, being the first and unique

spinner in Brazil.

SPINNOVATION: What are the main

benefits for your compact yarn

clients?

Mr. Bezerra: The main characteristic of

compact yarn is the reduced hairiness

and - as a consequence of the higher

resistance - you can spin with lower

twist, getting a better touch and dye-

stuff absorption.You can even make

savings in the use of dyeing agents. In

the weaving process you can reduce

the sizing application because of the

higher yarn strength.

SPINNOVATION: Did you make any

savings in cotton quality, noil or cotton

waste?

Mr. Bezerra: The percentage of cotton

waste on the ring spinning frame is

drastically reduced, but we are not

looking for savings in the spinning

process.We want to give the benefits

to our clients. Therefore we are now

using even better cotton, Pima-like

cotton.

SPINNOVATION: Are you spinning the

same yarn count as before?

Mr. Bezerra: Besides Ne 24, 30, 36 and

40 as we did before, we are now spin-

ning even Ne 45, 50 and Ne 60 for

knitting and weaving applications.

SPINNOVATION: Do you spin the yarn

with the same twist/same production

as in conventional spinning?

Mr. Bezerra: At the moment we are

spinning with the same twist factor, but

we realized very soon that it is poss-

ible to reduce twist, as compact yarn

has a much higher yarn strength. Now

we are studying this twist reduction

and we believe that this is possible up

to 5% less twist.

SPINNOVATION: Do you think that

compact yarn will substitute conven-

tional ring yarn in the future?

Mr. Bezerra: We believe so, maybe not

all the conventional yarn, but a major

part of it. Compact yarn is perfectly

suited for combed yarns of superior

quality, for an application range that

has not existed before.

SPINNOVATION: Do the clients in

Brazil already know the advantages of

compact yarn?

Mr. Bezerra: Yes, because in the begin-

ning we sent many samples to our

clients. All those samples found

approval and many of our clients are

now buying already for the 4th time in

less than 4 months.

Some clients do not buy imported

yarns any more, but they buy the yarn

now from TBM, appreciating all the

advantages of the compact yarn.

SPINNOVATION: It was a pleasure

talking to you. Thank you very much

for your time.

Joint Development in Open-End Spinning

with the Fibre Manufacturer

By Dr. Marco Torre, Montefibre S.p.A., Italy

Stephan Urmetzer, WST/Rieter Design Center, Germany

Antonio Durante, SUESSEN Sales Manager

The Joint Development

The Joint Development originally was

initiated by Dr. Torre and Mr. Durante.

The main goal was to unite the forces

while developing new fibres on the

one side and new SpinBox features for

man-made fibres on the other side.

The experience gained is beneficial

for both sides, as customers can be

better advised, and consequently the

sales success for both products -

SpinBox and fibres - increases.

Montefibre - Company Profile

Montefibre S.p.A. is an Italian Com-

pany holding a top rank at world level

in the acrylic industry, and at Euro-

pean level in the manufacture of

polyester fibres and PET polymers for

textiles and technical applications.

Currently, Montefibre S.p.A. has four

manufacturing sites, three in Italy

(Acerra, Ottana, Porto Marghera) and

one in Spain (Miranda de Ebro).

Montefibre S.p.A. is strongly commit-

ted to continuously innovating and

diversifying its product mix in the sec-

tor of higher added value, while rein-

forcing its R & D activities to provide

new answers to the industry’s chang-

ing needs and consumers’ quality

demands. As regards acrylic fibre

production, Montefibre S.p.A. is the

worldwide leader owing to its know-

how and technology, its great product

range and market share.

In the polyester sector, Montefibre

S.p.A., with its Acerra factory, is the

only European enterprise with a verti-

cal plant and a very advanced techno-

logy. This plant makes its own chemi-

cal agent DMT to feed the continuous

polymerization lines for the production

of a wide range of fibres and polym-

ers, suitable for all conversion techno-

logies.

Montefibre S.p.A., for the production of

polyester fibres, has been on the mar-

ket since 957 with the TeritalQ brand

name.

Today, TeritalQ is synonymous with a

comprehensive range of products,

able to meet any requirement of the

customers in the textile and nonwov-

ens industry.

Montefibre S.p.A.’s polyester product

range includes polymers and staples,

both row- and mass-dyed, for any end

use, in a variety of industrial sectors:

from apparel to furnishing, from auto-

motive to geotextiles, up to medical

and hygienic applications.

In addition to commodities, Montefibre

S.p.A. offers specialities like flame-

retardant fibres (Fidion fr), bioactive

fibres (TeritalQ Saniwear) and cationic

dyeable fibres.

SPECIAL FIBRES

TeritalQ T5 CD (cationic dyeable)

(.7 dtex / 38 mm): polyester staple

fibre suitable for all applications where

superior colour fastness and bright-

ness is required.

TeritalQ T5 CD is designed for differ-

ent end uses; it is particularly suited

for blends with standard polyester

for melange and colour effects; with

TeritalQ T5 CD it is possible to obtain

high colour fastness and dyeing uni-

formity.

TeritalQ T5 CD is even suitable for

blends with wool or with elastan fibres

to take advantage of its dyeing pro-

perties without using carriers in the

dyestuff at boiling temperature (00ΩC

on average).

SPINNOVATION No. 8

TeritalQ T5 CD used in 00% or in

blend with other fibres allows to obtain

a soft handle of the final fabrics.

TeritalQ T5 CD can be used for cloth-

ing as well as home furnishing.

TeritalQ Saniwear T5 AB

(.7 dtex / 38 mm): polyester staple

fibre with inherent antibacterial pro-

perties achieved by incorporating an

inorganic agent into the fibre which

ensures an effective and long lasting

activity against bacterial growth (i.e.

Bacillus Subtilis, Klebsiella Pneumo-

nia, Staphylococcus Epidermidis).

TeritalQ Saniwear antibacterial activity

is ensured according to the tests

(Shake Flask Test) carried out by qua-

lified and independent laboratories.

TeritalQ Saniwear fibre properties are

similar to those of a regular polyester,

so it can be processed along the tex-

tile chain where it is normally used at

00% or in blends both with regular

polyester or natural fibres.

The blend composition (% of TeritalQ

Saniwear) and the finishing processes

should be adjusted according to the

end use.

TeritalQ Saniwear comply with OEKO-

TEX standard 00 Product Class I and

even with UNI EN ISO 0993 part 0

regulation.

TeritalQ Saniwear can be used for clo-

things (polar fleece, active sportswear,

work clothing) as well as furnishing

(textile for bedding, tablecloth).

Fidion fr is a flame-retardant polyester

fibre with built-in fire-resistance and

self-extinguishing properties.

Chemically, it consists of polyethylene

terephtalate, with the only addition of

phosphorous compounds.

It does not contain any halogen pro-

ducts.

The inherent flame-retardant proper-

ties of Fidion fr is expressed as a cata-

lytic inhibition, raising the oxygen

quantity required for combustion

(L.O.I.).

Fidion fr is available in fibre form (sta-

ple, tow, top) for use in short- and

long-staple spinning, as well as in

direct uses (nonwovens, waddings,

fillings, etc.).

Fidion fr products have permanent

fireproof properties and resistance to

all kinds of washing processes, plus

the OEKO-TEX certification, guaran-

teeing the total absence of noxious

substances for mankind and environ-

ment.

Co-operation with SUESSEN

Spinning synthetic fibres on rotor

spinning machines is always a great

challenge due to the special fibre pro-

perties, in particular of PES fibres. This

is one of the rare cases when the pro-

duction limit is reached at a relatively

early stage, due to the material spun,

and not due to maximum rotor speed

or delivery.

For this reason it is of particular impor-

tance that SpinBox and accessories

are specially designed for the spinning

of synthetic yarns. This is the only way

to ensure that the characteristics of

newly developed fibres are evaluated

correctly and their utilization proper-

ties in the spinning mill can be asses-

sed in advance.

A co-operation of Montefibre S.p.A.

with SUESSEN and the WST Research

Centre was the obvious choice.

Within the scope of modernization of

rotor spinning machines, SUESSEN

offers the SC 2-M Compact SpinBox,

specially designed for processing

synthetic fibres. In combination with

spinning accessories, which meet the

particular demands of these fibres, a

package results enabling the custom-

ers to process synthetic fibres at the

highest quality level.

SPINNOVATION No. 8

This means in detail: If PES is spun at

too high a rotor speed, the heat gene-

rated at the navels leads to thermal

damages of the fibres. This becomes

noticeable either in spinning by a

reduced spinning stability, or in sub-

sequent processes by bad yarn qua-

lity. Therefore, the SC 2-M SpinBox is

equipped with a special navel for

polyester, which due to its geometry

and material allows higher rotor

speeds than navels used until now.

This special navel is the MIMA navel.

Production increase of 5 to 20% is

possible, and in most cases yarn qua-

lity is even improved. For a long time,

PES fibres were processed with steel

navels, which offered satisfactory

results for the moment, but generated

higher abrasion (Staff) and had a

shorter operating life than the MIMA

navel with its specially developed

ceramic. Another disadvantage is that

steel navels do not have uniform sur-

face properties and therefore are

unable to provide constant yarn para-

meters over a specified time.

The SC 2-M SpinBox is equipped with

the MIMA navel for processing polyes-

ter.We can therefore ensure that both

the fibre developing industry and spin-

ning mills are supported in the most

effective way.

Another feature of the SpinBox for

synthetic fibres is the newly developed

opening roller S 43. Apart from the risk

of thermal damages when spinning

PES and other synthetic fibres, there is

a risk of mechanical damages by the

opening roller. As a result, yarn quality

deteriorates, end-down rate increases

and dust accumulates in the SpinBox.

The tooth shape of the S 43 SOLID-

RING is thus to ensure a smooth and

careful opening of the fibre beard.

Furthermore, the SOLIDRING meets

another important demand. Fibres

should not only be combed and trans-

ported safely, but they should also

come off easily from the SOLIDRING

and be transferred to the fibre

channel. Otherwise, part of the fibre

mass will recirculate with the SOLID-

RING, accumulate and result in yarn

defects and end-breaks. Such fibres

are called ”merry-go-round” fibres.

SOLIDRING S 43 meets all these

demands – smooth fibre opening and

safe fibre transfer – and is therefore

used for evaluating newly developed

fibre types apart from being frequently

used in spinning mills.

SPINNOVATION No. 8

Finally the SpinBox itself. Owing to its

special air guidance, it facilitates the

fibre transport from the feed table over

the opening roller to the fibre channel

and the rotor. The transfer of fibres

from the SOLIDRING is supported by

a ”SpeedPass” on the one hand, which

provides additional air in the fibre

channel and consequently separates

the fibres safely from the opening

roller, and by a ”Swan Neck” on the

other hand, which enables the usually

very flexible synthetic fibres to come

off from the opening roller teeth.

Owing to all these features, the

SC 2-M Compact SpinBox and the

relevant spinning accessories is

the superior box for processing

synthetic fibres. Many spinning mills

already benefit from the advantages to

distinguish themselves from their

competitors.

The co-operation of SUESSEN with its

SC 2-M SpinBox and Montefibre

S.p.A., one of the leading producers of

synthetic fibres, is for the benefit of

both companies and finally for the

benefit of our customers.We will conti-

nue these joint projects to support

Montefibre S.p.A. with its innovations,

and the experience we acquire as

manufacturer of SpinBoxes will help to

improve our products according to

market requirements.

Electronic Yarn Detector

The Electronic Yarn Detector has been

designed to replace the mechanical

yarn detector system on Autocoro

Open-End Rotor Spinning Machines. It

offers the following advantages:

π Non-contact yarn motion control

π Winding tension adjustable to

technological requirements

π Minimized yarn elongation loss in

winding process

π Fast and precise stop of spinning

position in case of end-down

Disadvantages of mechanical yarn

detectors:

π Central adjustment of winding ten-

sion for the whole machine accord-

ing to the reliability of the most

unfavourable yarn detector to

avoid unmotivated release. This

tension level often exceeds the

technological requirements by far

and results in yarn elongation loss.

π Due to the own weight of the

detecting wire, a minimum winding

tension is required to prevent un-

intentional stop.

π Alternating mechanical yarn detec-

tors often cause unnecessary fibre

feed before the spinning position is

actually stopped, what increases

good fibre loss.

π High maintenance costs to avoid

overfeed due to malfunctioning

mechanical yarn detectors.

The Electronic Yarn Detector easily

solves all these problems of the

mechanical yarn detector.

The winding tension can be minimized

to obtain the softest packages poss-

ible required for a perfect dyeing

process.

The Electronic Yarn Detector is main-

tenance-free and resistant to wear.

Texas Tech Paper

on Compact Spinning

The International Textile Center of the

Texas Tech University in Lubbock (Tx),

USA, only recently published a most

interesting article in Textile Topics

Volume 2002-2, Spring 2002 con-

cerning

Compact Spinning: The New Poten-

tial for Short Staple Cottons

They evaluated the performance of dif-

ferent U.S. and Texas upland cottons

on modern conventional ring spinning

machines and the improvements in

performance resulting from compact

spinning. They concluded that the

compact yarn structure gets very

close to a maximum utilization of each

fibre in the yarn bundle. A higher yarn

strength is achieved from any fibres

used. However, the improvement

appears to be greater for shorter sta-

ple cotton than for longer staple cot-

ton. Fibres, inadequate for use in con-

ventional ring spinning, may be spun

satisfactorily on the compact system.

As expected, the compact spinning

system greatly reduced the yarn hairi-

ness. The spinning machines used

were the SUESSEN Fiomax 000 for

conventional ring spinning and the

SUESSEN Fiomax E (equipped with

EliTeQCompactSet) for compact ring

spinning.

ever increasing interest customers

have in compact spinning, particularly

in SUESSEN’s EliTeQSpinning Sys-

tem.

EliTeQCompactSet Installation

in P.R. China

In the Chinese Wuxi No. Cotton Mill,

SUESSEN equipped 25 Jingwei ring

spinning machines, type FA 506
