This standard specifies the definition, technical requirements, test methods, inspection rules and requirements for marking, labeling, packaging, transportation and storage of polyester low elastic yarn. This standard applies to polyester low-stretch yarns with a bus density of 30 dtex to 600 dtex, a single-filament linear density of 0.3 dtex≤dpf≤5.6 dtex, round cross-sections, and semi-dull polyester low-stretch yarns. Other types of polyester low-stretch yarns can be used as a reference.
