Scope

Main technical content: This document specifies the terms and definitions, product classification, marking, requirements, test methods, inspection rules, and marking for dyed yarns made from polyester-viscose blends with a double core of polyamide. This document applies to 22 dtex to 83 dtex polyester low-elastic filament and 22 dtex to 77 dtex polyamide as the double core, which is externally coated with polyester (cotton-type short fibers with a content of ≥50%) and viscose fibers (cotton-type short fibers). The technical requirements for dyed yarns made from polyester-viscose blends with a double core of polyamide include nine indicators: line density deviation rate, line density variation coefficient, single yarn breaking strength, single yarn breaking strength variation coefficient, evenness of yarn, cotton knots per kilometer (+200%), yarn defects per 100,000 meters, fiber content deviation, and appearance quality.
