Scope

This standard specifies the terms and definitions, classification and identification, technical requirements, test methods, inspection rules and marking, packaging, transportation and storage requirements for colored acrylic staple fiber and tow products. This standard is applicable to short fibers and tows made directly from multi-component copolymers with acrylonitrile as the main monomer by adding pigments during the preparation process of the original solution (solution coloring); or by adding dyes in the gel state for rapid coloring. (gel dyed) short fibers and tows; the nominal linear density of single fiber is 1.11 dtex~16.67 dtex. Other specifications and types of colored acrylic staple fibers and tows can be used as a reference.
