SN/T 3315.3-2012 (English Version) PDF

Scope: This part of SN/T 3315 specifies the sodium zincate method for the determination of viscose fiber, regenerated bamboo fiber, modal fiber, part of cupro fiber, Newdale fiber or mixture of hemp fiber and cotton fiber after removing non-fibrous substances. Methods for quantitative fiber analysis. If there are regenerated cellulose fibers other than viscose fiber and regenerated bamboo fiber in the sample, it should be tested in advance whether it is soluble in the reagent. The method in this section is applicable to blended products of regenerated cellulose fiber and cotton. This section does not apply if the cotton fibers in the mixture have been severely chemically degraded, nor does it apply if the viscose fibers, regenerated bamboo fibers, modal fibers, cuprammonium fibers, Newdale fibers or hemp fibers contain fibers that cannot be completely removed. Durable finishing agents or reactive dyes that prevent them from completely dissolving.
