Advantage
1. The basic composition of viscose fiber is cellulose (C6H10O5)n o The cross section of ordinary viscose fiber is zigzag skin core structure, and the longitudinal and straight trenches are horizontal. The rich fiber has no skin core structure and a circular cross-section.
2. Viscose fiber has good hygroscopic properties, and the moisture regain rate is about 13% under general atmospheric conditions. After hygroscopic expansion, the diameter can be increased by 50%, so the fabric feels hard after launching, and the shrinkage rate is large.
3. Viscose fiber is similar in chemical composition to cotton and is more alkali resistant. Rich fiber has good alkali and acid resistance.
4. The chromatographic staining was complete and the dyeing performance was good.
5. The thermal properties of viscose fiber are also similar to cotton, with a density close to cotton of 1.50~1.52g/cm3.
