Textile Materials Made from Polyolefins (Excluding Cordage) Sectional Committee, TXD 23

FOREWORD

This Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by
the Textile Materials Made from Polyolefins (Excluding Cordage) Sectional Committee had been approved by
the Textiles Division Council.

This standard was first published in 1971 and subsequently revised in 1984 and 1994. It has been revised again
on the basis of experience gained since its last revision and to amalgamate IS 6193 ‘Methods of tests for
monoaxially oriented high density polyethylene tapes’ and IS 11197 ‘Specification for monoaxially oriented
polypropylene tapes’ and also incorporate the following major changes:
a) The requirement for ash content and its test method has been specified;
b) All amendments have been incorporated;
c) Marking requirements have been modified to include the environment friendly recycling logo on the tape
package; and
d) Sampling and criteria for conformity have been modified.

The monoaxially oriented flat tapes are manufactured using thin film extrusion technology in which wide width
film is slit into narrow tapes which are subsequently stretched at elevated temperature. By doing so, the polymer
molecules are oriented in a longitudinal direction resulting in considerably improved tensile strength in that
direction combined with the reduction in linear density of tapes. Monoaxially oriented flat tapes are commonly
used in the manufacture of woven fabrics.

In the last two decades, several technological developments have taken place in polymer materials and their
performance, tape yarn manufacturing technology, tape yarn testing and analysis procedures and, the market
requirements. This has called for the revision of the existing standards on the subject to make it in line with present
requirements.

The composition of the Committee responsible for the formulation of this standard is given in Annex H.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final values,
observed or calculated, expressing the results of tests, shall be rounded off in accordance with IS 2 : 2022 ‘Rules
for rounding off numerical values (second revision)’. The number of significant places retained in the rounded off
values should be the same as that of the specified values in this standard.
