GB/T 45514-2025 Textiles—Quantitative chemical analysis—Mixtures of polyarylate with certain other fibers
Basic Information
Scope
This document describes a method for determining the fiber content in a two-component mixture of polyarylate fibers and certain other fibers after removing non-fiber substances using chemical analysis methods.
This document is applicable to two-component mixtures of polyarylate fibers and certain protein fibers (sheep wool, silk, etc.), regenerated cellulose fibers (Lyocell fibers, Modal fibers, viscose fibers, etc.), natural cellulose fibers (cotton, flax, ramie, etc.), polyester fibers, polyamide fibers, polyvinyl alcohol fibers, polyacrylonitrile fibers, certain modified polyacrylonitrile fibers, polyurethane elastic fibers, acetate fibers, triacetate fibers, polylactic acid fibers, ortho-aromatic polyamide fibers, and meta-aromatic polyamide fibers. Note: Appendix A provides the identification characteristics of ortho-aromatic polyamide fibers, meta-aromatic polyamide fibers, and polyarylate fibers.
