Indian Standard

SPECIFICATION FOR UNTEASED WHITE COTTON WASTE

( First Revision )

0. FOREWORD

0.1 This Indian Standard ( First Revision ) was adopted by the Indian, Standards Institution on 15 November 1979, after the draft finalized by, the Cotton and Cotton Products Sectional Committee had been approved. by the Textile Division Council.

0.2 This standard, first published in 1972, has been revised to align it with the purchaser’s requirements in order to facilitate complete adoption: of the standard by the industry. The moisture content has been increased to 9 percent and the requirement in respect of foreign matter including dirt and grit content has been included in this revision.

0.3 In the preparation of this standard, assistance has been drawn from G/Tex/C-124D Specification for cotton waste ( reeling waste ), white ( unteased ) for axle box packing, issued by the Directorate General of Supplies & Disposals, Government of India.

0.4 To familiarize the industry with International System’ of Units ( SI Units ) the basic SI units as well as the recommended SI Units for use in the textile industry are given in Appendix B.

0.4.1 Standards of Weights and Measures Act 1976 also stipulates use of SI Units.

0.5 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, express- ing the result of a test, shall be rounded off in accordance with IS : 2:1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

*Rules for rounding off numerical values (revised).

IS t 6612 - 1979

1. SCOPE

1.1 This standard specifies the requirements for unteased white cotton waste used in axle-box packing.

2. MANUFACTURE

2.1 The material ( cotton waste ) shall be obtained from the yarn remnants collected from the ring spinning, reeling, winding and warping depart- ments of cotton textile mills.

2.2 The material shall consist of unsized and undyed yarn only.

2.3 The material shall be reasonably free from dust, fluff, loose cotton, roving, piecer’s waste, doubling, dirty or soiled yarn, oily or greased yarn, cuts and small bits.

2.4 The material shall also be reasonably free from foreign materials such as leaf particles, wood particles, rags and any reclaimed waste.

3. REQUIREMENTS

3.1 The material shall conform to the requirements given in Table 1.

4. PACKING

4.1 The material shall be packed in hessian bags ( see TS : 3790-1971*) or high density polyethylene woven sacks ( see IS : 6340-1971t ). The net mass of the bags shall be’approximately 100 kg.

*Specification for hessian bags (Jirsl revision ). $Specification for high density polyethylene woven sacks.

IS : 6612 - 1979

5. MARKING

5.1 Each bag shall be marked with the following:

a) Name of the material;

b) Serial number; c) Supplier’s name, initials or trade-mark, if any; and

d) Gross and net mass.

5.1.1 The bag may also be marked with the IS1 Certification Mark. NOTE - The use of the IS1 Certification Mark is governed by the profov ssion

the Indian Standards Institution ( Certification Marks) Act and the Rules and Regulations made thereunder. The IS1 Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-defined system of inspection, testing and quality control which is devised and supervised by IS1 and operated by the producer. IS1 marked products are also continuously checked by IS1 for conformity to that standard as a further safeguard. Details of conditions under which a licence for the use of the IS1 Certification Mark may be granted to manufacturers or processors, may be obtained from the Indian Standards Institution.

6. SAMPLING

6.1 Lot - The quantity of cotton yarn waste supplied to a buyer against one despatch note shall constitute a lot. The conformity of the lot shall be determined on the basis of the tests carried out on the sample selected from it.

NOTE - The lot shall not weigh more than 25 OCO kg.

6.2 Unless otherwise agreed to between the buyer and the seller, at least 5 bags shall be selected at random from a lot.

6.3 Sufficient material from each bag shall be drawn at random. The material drawn from these bags shall be thoroughly mixed to form a com- posite sample weighing about 5 kg. Three test specimens of approximately equal mass shall be drawn from the composite sample for testing the various characteristics.

6.4 One of these three specimens selected at random shall be tested for all the requirements and the other two be retained separately for retesting, if required.

6.4.1 The lot shall be declared as conforming to the requirements for various standard if the test specimen satisfies the requirements for various characteristics.

6.5 Retest - In case the specimen fails to satisfy even one of the require- ments, then the other two test specimens kept separately shall be put to test. The lot shall be considered acceptable if none of these two test specimens fails to satisfy the requirements.

APPENDIX A ( Table 1 )

METHOD FOR DETERMINATION OF DIRT, GRIT AND FOREIGN MATTER

A-l. From the test specimen take about 1 kg of cotton waste and weigh it accurately. Pick out the foreign matter including soft waste, fluff, loose cotton, etc.

A-2. Spread the waste uniformly in a 1.70 mm sieve placed on ground or a table suitably covered with white paper. Open out the specimen thoroughly inside the sieve, taking care that while opening no fibre falls out of the sieve. Lift the sieve and shake it horizontally 50 times. Pick up the bits of fibres that may fall on the paper along with the dirt and grit.

A-3. Determine accurately the mass of:

a) dirt and grit ( see A-2), and

b) foreign matter (see A-l ) alongwith the fibre bits (see A-2 ).

A-4. Express the amount of:

a) dirt and grit,

b) foreign matter including the dirt and grit, and

c) as percentage of the original mass of the test specimen.
