0 FOREWORD

0.1 This Indian Standard ( First Revision ) was adopted by the Indian Standards Institution on 11 January 1982, after the draft finslized by the Narrow Fabrics, Webbings and Braids Sectional Committee had been approved by the Textile Division Council.

0.2 This standard was first published in 1968 and for preparing this standard considerable assis- tance was derived from the following standards:

IND/TC/0303 Laces, fabric. Ministry of Defence.

V-L.51 Federal Specification for laces, shoe; cotton Section IV ( Part 5 ) of Federal Standard Stock Catalog. United States of America.

0.3 Recommended use of the laces covered in the standard is as follows:

IS 4778 : 1982

0.4 This standard contains clause 3.2 which calls for agreement between the buyer and the seller for permitting the buyer to use his option for selection to suit his requirement.

0.5 The Standards of Weights and Measures. Act, 1976 stipulates the use of the International: System of Units in the country; in order to fami-- liarize the industry with this system, the recom- mended SI Units for use in the textile industry are given in Appendix B.

0.6 For the purpose of deciding whether a parti- cular requirement of this standard is complied with, the final value, observed or calculated, expressing 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.

1 SCOPE

1.1 This standard covers braided tubular cotton: lances to be used for footwear.

2 MATERIALS

2.1 Yarn

The cotton yarn used in the manufacture of laces should be conforming to Grade A or B of IS 171 : 1973t.

2.2 Laces

The colour of laces and tags shall be as specifies in the contract or order.

2.2.1 Dyeing

The shoe laces shall be dyed to the required’ shade using suitable dyes.

2.2.2 For black laces manufactured against Defcnce orders, sulphur dyes shall not be used.

2.3 Tags

Both ends of the lace shall be provided with tags. of metal or plastic materials. The metal tags shall be coated with varnish or shall be of the same colour to match with the laces. In the case of- laces required by Defence ( L 145136, L 115/36,

IS 1778 : 1982

L 100/36, L 60/36,L 63/25) metallic tags shall be used unless otherwise specified. The length of the tags shall be not less than 15 mm. The metallic tags shall not have rough joints, shall grip the lace firmly and the laces shall protrude about 2 mm out of the tip of the tag at either end.

2.3.1 Plastic tags shall be so fitted that the wisp- over is heat-sealed and the plastic materials fused and sealed so as to be an integral part of the lace. The plastic material used for tags shall be at least 0’15 mm thick.

3 REQUIREMENTS

3.1 The requirements for shoe laces for general use are given in Table 1 while those for D:fence use in Table 2.

IS 4778 : 1982

test specimens shall preferably be conditioned in the standard atmosphere for 48 hours.

A-l.2 The determination of mass and slip resis- tance shall be carried out in the standard at- mosphere and all other tests shall preferably be carried out in the standard atmosphere.

A-2 LENGTH

A-2.1 Measure the length of 2 tags on the test specimen to the nearest millimetre. Measure the length between the inner grips of the 2 tags by applying a tension of 28 =t 0’5 gf ( 274 rt 5 mN ) on the lace. The sum of these two measurements shall be taken as the length of the lace in the test specimen.

A-3 SLIP RESISTANCE

A-3.1 Apparatus

A suitable power-driven tensile strength testing machine with a rate of traverse of 115 f 12 mm/ min and a xlamp with 5 kg weight for appli- cation of tension on the specimen.

A-3.2 From a slip knot ( SPB Fig. 1 ) with its knot in the centre of ~the specimen, clamp *one end A of the specimen centrally in the upper Jaw, then clamp a 5 kg weight for a period of 10 se- conds at B. Remove the 5 kg weight and clamp

Operate the machine and record the highest load registered during the slipping of the first 50 mm of the lace through the slip knot. Continue to operate the machine until the knot is undone. Take the average of 6 results on each lace as the slip resistance.

Apparatus

A suitable power-driven tensile strength testing machine with a rate of traverse of 1 I5 f 12 mm/min.

Slotted Plate (see Fig. 2 ) -A rigid metal plate of suitable dimensions with a vertical edge tapered slot along the length of the plate. Jn conjunction with the slotted plate, use the upper jaw of the testing machine to keep the slot at right-angle to the direction of application of load during the test.

A-4.2 Procedure

Move the conditioned test specimen with one of its tags uppermost horizontally along the slot until both sides of the base of the tag rest on the top of the slotted plate. Centre the plate so that longitudinal axis of the test specimen is along the axis of the application of the load. Apply by hand an initial tension sufficient to strengthen the lace. Clamp the free end of the straightened specimen in the pulling jaw so that the free distance between the upper grip and the pulling jaw is 100 mm at the start of the test. Operate the machine and record the highest load registered before the tag is pulled from the lace. Discard the result and test another specimen if:
