Scope
Scope: This document is applicable to various textiles made from a blend of chitosan fibers and cotton or wool fibers; Main technical content: This document describes a method for determining the content of chitosan fibers in a two-component mixture composed of chitosan fibers and cotton or wool fibers after removing non-fibrous substances using the glacial acetic acid method. The chitosan fibers are dissolved and removed from a mixture of known dry mass using a glacial acetic acid solution, and the residue is collected, washed, dried, and weighed. The percentage of the chitosan fibers in the dry mass of the mixture is calculated using the corrected mass. The mass percentage of the chitosan fibers is calculated from the difference
