FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Narrow Fabrics, Webbings and Braids Sectional Committee had been approved by the Textile Division Council.

For the purpose of deciding whether a particular 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 ‘Rules for rounding off numerical values ( revised)‘. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

TEXTILES - HIGH DENSITY POLYETHYLENE MONOFILAMENT NEWAR - SPECIFICATION

1 SCOPE

1.1 This standard prescribes the requirements for three grades for high density polyethylene ( HDPE ) monofilament newar.

2 REFERENCES

2.1 The Indian Standards listed at Annex A are necessary adjuncts to this standard.

3 MATERIAL

3.1 The newar shall be made out of high density continuous monofilament polyethylene yarn having a relative density of 0’95 to 0’96.

4 REQUIREMENTS

4.1 The newar shall conform to the physical requirements as specified in Table 1.

4 2 The dyed newar shall also conform to the requirements as given in Table 2.

4.3 Creep

The average creep of the five samples when tested according to the methods given in Annex B shall not be more than 5’5 percent.

5 PACKING

5.1 The newar shall be supplied in rolls and packed as per the contract or order.

6 MARKING

6.1 Bach roll of newar shall be suitably marked with the following informaltion:

a) Name of the material and grade;

b) Length ( m ), width ( mm ); and c) Indication of the soure of manufacture.

6.2 Each package shall be marked with the number of rolls in the package in addition to those markings given in 6.1.

6.3 The roll and package may also be marked with the Standard Mark.

7 SAMPLING AND CRITERIA FOR CONFORMITY

7.1 Lot

The rolls of the same width and grade delivered to a buyer against one despatch note shall constitute a lot.

7.2 The sample rolls shall be selected at random as per IS 4905 : 1968 as given in Table 3.

ANNEX B ( Clause 4.3 )

METHOD FOR DETERMINATION OF CREEP

B-l PROCEDURE

B-l.1 Take a sample of newar of length 1’2 metre.

B-l.2 Draw two lines on the sample, transverse to the warp direction and 100’0 f 0’1 cm apart. When marking these lines, the newar shall be laid on a smooth flat surface and the minimum necessary tension should be applied to it to keep it straight.

B-l.3 Suspend the webbing vertically from a rigidly fixed clamp.

B-l.4 Fix a second clamp to the free end of the specimen and add weight to this clamp slowly so that the total weight suspended by the newar is 10 kg. The distance between the two clamps, that is the distance between two transverse lines, shall be more than 1 m [ say this length is(lOO+ l)cm].

B-l.5 Measure the distance ( L ) between the transverse lines marked on it after the tension has been applied to the specimen for 24 hours.

B-l.6 The value [ L - ( 100 -I- 1 ) ] is the percentage creep for the specimen.
