IS 1671 : 1977 Method for determination of yarn strength parameters of yarn spun on cotton systems

1 Scope

1.1 This standard prescribes methods for determination of yarn strengthparameters of yarns spun on cotton system using cotton count and tex system.

1.1.1 In cotton count system, determination of lea breaking load and countstrength product (CSP) have been prescribed and in the metric system,determination of skein breaking load, yarn strength index (YSI) and skeinbreaking tenacity (SBT) have been prescribed.
