The TEXTECHNO Product range For 60 years Textechno has been one of the leading producers of testing instruments for the textile-

and chemical fibre industry. The Textechno scope of supply comprises – among others –

well-known and proved automatic tensile testers for yarns (STATIMAT) and fibres (FAVIMAT,

FAVIGRAPH), automatic crimp-contraction testers for textured yarns (TEXTURMAT), or dynamic

filament-yarn testers for POY, FDY, FOY, DTY, and BCF (DYNAFIL).

At the forthcoming ITMEX Textechno will introduce several new and innovative testers:

Automatic tensile-, evenness-, and count tester STATIMAT DS

The most important properties of yarns are tensile strength and elongation, mass unevenness, and

yarn count (linear density). Static tensile testers, yarn evenness testers, as well as various apparatus

for yarn count testing, e.g. by means of wrap reel and balance, serve for the assessment of these yarn

properties. The use of different test equipment, to which the yarn samples are presented by the

operator one after another, results in high expenditure of labour and, especially in case of modern

automatic computer-controlled testing equipment, in considerable financial investment.

Such shortcomings are overcome by the new STATIMAT DS, which combines testing of tensile

properties, unevenness, and count of yarn and thread in one tester. The three tests on each package

presented by the package changer are performed in succession. Optionally it is possible to test

unevenness and yarn count in one test run, which enables to relate the results of both measurements

to the same tested yarn length.

A further optional accessory is an optical entanglement sensor to measure interlaces in a multifilament

yarn.

With regard to testing technology and technical realization the STATIMAT DS offers numerous

technical and technological novelties – for example a patented new capacitor design for measurement

of unevenness –, united with a new design philosophy.



Automatic tensile-, evenness-, and count tester STATIMAT DS

Essential advantages of the STATIMAT DS:

• Common use of all peripheral components of the tester like package changer, threading

mechanism for introducing the yarn sample into the test sections, yarn feeding device, waste yarn

disposal, instrument housing with protective front panel, as well as control electronics including the

PC-based Textechno TESTCONTROL system for the different test modules built in, which leads

to a very economic price of the STATIMAT DS compared to 3 separate testing appliances.

• The operator has to present the test samples (yarn packages) only to one instead of several

different testers, which results in considerable time- and labour savings. All measured data are

presented in one test protocol, so that the data can be easily interrelated, for example to calculate

tenacity from the measured strength- and yarn-count values.



Innovative high-speed weak spot tester DYNAJET

Breaking strength is an important characteristic of a yarn with regard to its performance in downstream

processing and to the properties of the ready-made fabric. Conventional tensile tests determine the

tensile strength – average value and coefficient of variation – from a relatively small number of

measurements on yarn sections of typically 500 mm length. On the other hand, staple-fibre spun yarns

inevitably contain so-called weak spots with very low breaking strength, for example thin places, yarn

segments with inclusions of foreign matter, or sections with thermal damage, which are normally not

detected in such standard tensile tests as they occur in very low numbers over kilometers of yarn

length.

The concept of the new DYNAJET focuses at detecting such weak spots on the running thread at high

speed. For this purpose the yarn passes with up to 1000 m/min through a test section and thereafter

through a casablanca type feeding device into a suction orifice. Within the test section the yarn is

subjected to a tensile force which remains absolutely constant throughout the test. The level of this

tensile force can be freely selected to simulate actual manufacturing process conditions. In case of

yarn rupture the tester stops immediately for subsequent rethreading.

Beside its very high level of efficiency the test method is characterized by its particular simulation of

manufacturing processes. In both cases the yarn runs with high speed into a zone with high tensile

stresses, resulting in extremely high rates of loading.

The DYNAJET offers to all yarn-producing and -processing units a new and extremely efficient method

to measure weak spots in a particular yarn material, and to forecast from this the expected number of

yarn breaks in further processing. Such measurements can be an important support to the yarn-

purchasing department. On the other hand, knowing the frequency of weak spots can help to adjust

manufacturing conditions in order to minimize ends down in the following processes.



Fibre length- and strength tester FIBROTEST

Fibre length and breaking strength determine to a large extent the processing of cotton fibres into

yarns and the properties of the yarn itself. Fibre length measurements according to the FIBROGRAPH

system, in which the fibre length is optically measured on a fibre bundle, feature a number of different

parameters such as 2.5 percent or 50 percent span length, mean length, etc.

Fibre strength is measured on fibre bundles, too. As this bundle strength depends on the thickness of

the fibre bundle, precise measurement of strength in g/dtex requires weighing of the fibres between

the clamps with high accuracy.

Present testing instruments are either purely manually-operated devices for each of the two test

methods, or fully automatic "high-volume" test stations requiring calibration with calibration cotton.

The new FIBROTEST of Textechno incorporates both fibre length measurement and fibre strength

test within the same instrument. Both measurements – at first fibre length and thereafter fibre strength

– are executed in succession. After completing these measurements the sample cross section

between the clamps is automatically determined, which enables to calculate the exact and absolute

value of tenacity (cN/dtex or psi). In this way problems resulting from the use of "calibration cotton" are

absolutely avoided.

Operation of the tester is simple and straightforward: The operator prepares the sample with the same

type of sample holder as used in other equipment known on the market, inserts the sample holder into

the tester, and starts the test. Results for fibre length and strength of one sample are available after

less than a minute.



Fibre length tester LENGTHCONTROL LCT

The LENGTHCONTROL (LCT) was originally developed by Trützschler and is based on Trützschler

technology, Textechno has taken over worldwide marketing of the tester. LCT measures fibre length

on a sample taken automatically from a sliver. Beside staple length as the classic test value

corresponding to the 2.5 percent span length value of the FIBROGRAPH measurement, LCT delivers

further results such as leading and trailing fibre hooks, short-fibre length, short-fibre content, and

staple gradient. From those results it is possible to optimize machine settings like cylinder speed and

distance of a carding machine, draft ratio in the main draft of the draw-frame, or combing percentage

at the combing machine. The tester has a rigid housing on solid castors, which enables operation on

the production floor.

New features of the LCT are the fibre length measurement on raw cotton material and the

determination of neps.



Besides the above new testers Textechno provides a wide range of well-accepted testing instruments

for the textile industry.

The STATIMAT ME+ is the standard automatic tensile testing instrument for threads operating on the

principle of constant rate of extension (CRE), with a force measuring range of up to 1000 N and a

package changer up to 50 positions. It meets the requirements of all important national and

international standards. The application range can be extended by using other sample holders for

tensile tests on fabrics including Grab tests, seam strength tests, separation force tests, or tongue and

tear tests, as well as tests on yarn skeins and other sample forms.

The STATIMAT 4U was developed to meet the requirements of tensile testing of very coarse and

high-tenacity threads up to maximum strength values of 5000 N. Special features like heavy duty

clamps with patented automatically operated bollards and a - likewise patented - rotary clamp to apply

a twist to the yarn prior to tensile testing make the STATIMAT 4 unique in the field of automatic tensile

testing of threads. STATIMAT 4 is suitable to test even Aramide and high-tenacity Polyethylene yarns

delivering maximum strength values. High operational speed is provided by a fast moving threading

arm. Like the STATIMAT ME, the STATIMAT 4 has a nip roll feeding device and can be equipped with

an AUTOCOUNT unit for automatic yarn count determination.

A further model of TEXTECHNO’s scope of automatic tensile and linear density testers is the

STATIMAT MEL+. Offering a high resolution (10 µN ≈ 1mg) load cell this instrument is TEXTECHNO’s

response to the increasing importance of elastomeric yarns, which – according to international

standards – are to be tested with a pretension of 0.01 cN/tex. Due to it’s unique resolution, the

STATIMAT MEL is capable of testing both bare Elastane (Spandex) as well as elastic combination

yarns with this extremely low pretension leading to correct elongation values.

A complete set-up for automatic filament yarn testing is based on the universal filament tester

DYNAFIL ME. This tester combines the methods of testing a running yarn at constant extension and

testing at constant force in one instrument. This concept, together with a high-temperature heater,

yarn delivery rollers operating at up to 1000 m/min, high-resolution force measurement technology, as

well as a high-precision pretensioning device, gives rise to a new dimension in yarn testing in the

filament yarn field. The most important end-use sectors for the DYNAFIL ME are:

• Draw-force testing of preoriented or fully drawn yarns

• Crimp contraction testing of textured yarns

• Shrinkage testing of yarns of all types



Two automatic package changer models are available to enable continuous testing of multiple

packages. For an even more comprehensive application DYNAFIL ME is completed by the automatic

linear density tester COMCOUNT with optional sample preparation for spin finish analysis, a

capacitive evenness tester COVAFIL, an optical entanglement test system as well as devices for the

measurement of friction and broken filaments.

Another well-proved and established crimp and shrinkage tester for yarns is the TEXTURMAT ME+.

This instrument measures crimp contraction, crimp module, and crimp stability on hanks of textured

yarns based on the German standard DIN 53840, which can today also be regarded as the

international standard test method for textured yarns. Another testing procedure of the TEXTURMAT

is the shrinkage testing, in which the length change of yarn hanks resulting from dry or wet heat

treatment is determined. The measurement is effected fully automatically on up to 30 yarn hanks

arranged in a magazine. The same magazine can be inserted into an oven or a hot-water bath for

development of the yarn crimp or release of the yarn shrinkage.

Efficiency is also an argument in favour of TEXTECHNO’s single fibre testers. An outstanding example

for this is the automatic fibre test system FAVIMAT-AIROBOT2. The FAVIMAT is the first and only

tester to combine four single-fibre test methods in one instrument on the same section of the fibre:

• Fibre fineness

• Tensile properties

• Mechanical crimp properties

• Geometrical crimp structure

The test process can be fully automated by the means of the AIROBOT system linked to the

FAVIMAT. The AIROBOT system consists of a tensionless storage for up to 500 fibres together with a

fully automatic transfer system, which feeds the fibres to the FAVIMAT testing instrument without

using pretensioning-weights. Compared to conventional testing equipment, the FAVIMAT-AIROBOT

reduces labour time by as much as 95 percent, depending on the type of tests involved.

The FAVIMAT can be used to test a wide variety of fibres, including Aramide, UHMPE and Carbon

fibres. TEXTECHNO recently succeeded to modify the AIROBOT such way, that test on Carbon fibres

can be carried out automatically. Another new application of the FAVIMAT AIROBOT2 is to measure

metal-to-metal friction automatically.



TEXTECHNO’s solution for those customers, who need only a fast tester for single fibre linear density

and tensile properties, is the FAVIGRAPH. The linear density measuring head is arranged adjacent to

the tensile test section. An integrated transfer clamp serves to displace the fibre from one to the other

measuring system. Therefore, the operator has to insert the fibre manually only once into the linear

density test section. After testing the linear density the transfer clamp automatically turns to the

tensile test section and places the fibre into the measuring and the draw-off clamp. During tensile

testing the next fibre can be inserted into the linear density measuring head, which leads to a

considerable increase in testing efficiency. As additional options, tensile tests in wet state as well as

fibre bundle strength tests are also possible with the FAVIGRAPH.

HELFIS is the first system for semi-automatic single fibre shrinkage tests, based on digital image

analysis. For hot air heat treatment TEXTECHNO developed their so-called HEATLIFT system, which

avoids the well known problems of conventional heating cabinets. A hot water bath for releasing

shrinkage is also available.

FIBRESTRESS is a fatigue tester for single fibres or filaments with numerous applications in fibre

development and production control (low pilling Polyester fibres, carpet fibres etc.).

In 2004 TEXTECHNO has taken over LENZING INSTRUMENTS in Lenzing, Austria.

LENZING INSTRUMENTS was founded in 1965 and started its business with the production of

tensile- and linear density testing equipment for staple fibres. In the following years a wide range of

quality testing instruments for staple fibres and filament yarns have been developed. A new field of

activity is the online measurement (OLM) for the production of filament yarns, staple fibres and non-

wovens.

Both companies, TEXTECHNO and LENZING INSTRUMETS, welcome you in the German pavilion of

the ITMEX 2009 at the Anhembi fairgrounds, São Paulo, Brazil.
