GB/T 2910.4-2022 Textiles—Quantitative chemical analysis—Part 4:Mixtures of certain protein fibres with certain other fibres(method using hypochlorite)
Abstract
This document specifies a method for determining the content of protein fibers in certain mixtures of two components consisting of protein fibers and certain non-protein fibers after removing non-fibrous substances, using the hypochlorite method:
—— Sheep wool, other animal hair fibers (such as cashmere, horsehair), silk, regenerated protein fibers, and
—— Cotton, cupro, viscose fibers, modal fibers, lyocell fibers, polyacrylonitrile fibers, chlorine-containing fibers, polyamide fibers, polyester fibers, polypropylene fibers, glass fibers, polyurethane elastic fibers, polyester composite elastic fibers, polyolefin elastic fibers, melamine fibers, and polypropylene/polyamide composite fibers.
