Abstract
This part of GB/T 2910 specifies the method for determining the fiber content in viscose fibers, certain cuprammonium fibers, modal fibers, or lyocell fibers, and mixtures of flax and ramie after removing non-fibrous substances by using the formic acid/zinc chloride method.
This part is not applicable to mixtures in which the viscose fibers, certain cuprammonium fibers, modal fibers, or lyocell fibers cannot be completely dissolved due to the presence of durable finishing agents or reactive dyes that cannot be completely removed.
