Scope

Scope: This document specifies the terms and definitions, marking, technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage for recycled polyester and spandex core-spun yarns in their natural colors. This document applies to recycled polyester and spandex core-spun yarns produced by ring spinning. Recycled polyester blended with spandex core-spun yarns produced by ring spinning can be used as a reference (the recycled polyester content should be no less than 50%). Main technical content: The main technical requirements of this document include fiber content deviation, linear density deviation rate and linear density variation coefficient, single yarn breaking strength and breaking strength variation coefficient, evenness of yarn deviation coefficient, yarn defects per kilometer, yarn defects per 100,000 meters, and core-spun yarn defects (hollow yarn defects, poorly coated yarn defects, and exposed core yarn defects).
