Scope

This standard specifies the terms and definitions, product identification, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage requirements for island polyester drawn yarn. This standard is applicable to products produced with alkali-soluble polyethylene terephthalate as the sea phase and polyethylene terephthalate as the island phase. The total linear density is 55.6 dtex ~ 166.7 dtex, and the single-filament linear density after fiber opening is 0.03 dtex～0.19 dtex, circular cross-section, semi-dull, full-dull island polyester draft yarn. Other types of island polyester draft yarn can be used as a reference.
