Scope

Scope: This document specifies the terms and definitions, product specifications, technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of hydrophilic polyester hetero-shrinkage blended filament yarns. This document is applicable to one-step hydrophilic polyester hetero-shrinkage blended filament yarns with a linear density of 30 dtex to 300 dtex and a single filament linear density of 0.5 dtex to 3 dtex. Main technical content: Hydrophilic polyester hetero-shrinkage blended filament yarns are a new type of differentiated functional modified polyester fiber material, which integrates and synergistically combines multiple technologies such as polymer modification, spinning, spinning, weaving, and dyeing and finishing. Hydrophilic polyester modifies the macromolecular structure to change the fiber's properties and add new functions. For example, by means of copolymer modification, easy-dyeable groups and hydrophilic groups are introduced into the polyester macromolecular structure, which enhances the dyeability and moisture regain of the fiber, with a moisture regain rate more than three times that of ordinary polyester fibers on the market. The capillary effect of the highly fluffy fiber gaps increases the evaporation area, allowing the fabric to promptly absorb and quickly disperse the moisture generated on the surface of the body, maintaining human comfort and comfort. Therefore, moisture regain is an important indicator for judging the performance of hydrophilic polyester hetero-shrinkage blended filament yarn products. Since hydrophilic polyester is a modified polyester product, the molecular structure has undergone significant changes, resulting in reduced spinnability. Therefore, product weight and length are an important indicator for judging the spinnability of hydrophilic polyester. Hetero-shrinkage rate is an important indicator of the performance of blended filament yarns. The higher the hetero-shrink
