Revised Standard from Last Update.

1. SCOPE

1.1 This standard prescribes a method for the determination of crimp and linear density (direct or indirect count) of yarn removed from any textile fabric in which yarns are intact and can be removed in measurable lengths. In case the fabric contains plied or cabled yarn, the method is applicable for the determination of its resultant linear density.

1.2 The linear density of yarn determined by this method may not, however, be expected to agree with the linear density of grey yarn used for weaving the fabric because of the changes brought about in the yarn linear density by the processing treatments as well as the treatments prescribed in this standard for removal of the added matter.

1.3 This standard is applicable to yarns that stretch less than 5 percent when tension on yarn is increased from 0.25 g/tex to 0.75 g/tex. By mutual agreement, it may be adapted to yarns that stretch more than 5 percent by use of pre-tension lower than the specified method for elastomers or use of tension higher than that specified in this method to remove crimp out of textured yarns.
