Scope
This document describes a method for determining the fiber content in a two-component mixture of polyphenylene oxide fibers after removing non-fiber substances by chemical analysis.
This document is applicable to two-component mixtures of polyphenylene oxide fibers with certain protein fibers (sheep's 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, and certain meta-aromatic polyamide fibers.
Note: Appendix A provides identification test methods for meta-aromatic polyamide fibers, para-aromatic polyamide fibers, and polyphenylene oxide fibers.
