Scope

This Standard specifies the testing method for twist of man-made fibre filaments
such as polyester, polyamide (chinlon), polypropylene, cellulose fibre.
[Translator note: There is additional 1 nick-name for polyester and
polypropylene respectively in Chinese.]
This Standard applies to the determination of the twist of man-made fibre
filaments with twist. The man-made fibre filament drawn from the fabric can
refer to it for use.
This Standard does not apply to filaments with an elongation greater than 0.5%
when the tension increases from 0.05 cN/dtex to 0.1 cN/dtex.

Summary	This standard specifies the polyester (PET), polyamide (nylon), polypropylene (PP), test methods such as chemical cellulose fiber filament twist. This standard applies to the determination of chemical fiber filament with twist twist. Extracted from the fabric may refer to the use of chemical fiber filament. This standard does not apply when the tension from 0. 05cN/dtex to 0. 1cN/dtex elongation greater than 0. 5% of the filaments.
