Along with the increasing demand for fashion and comfort in garment, with environment-friendly, good spinnabilty, easy to dye and comfort viscose fiber has become popular fabrics in various garment and textile industries. Expecially it conforms to the trend of low-carbon life ,viscose fiber market emerged as the times reuqire, the need of viscose fiber grows smooth and fast.

Now Let us learn what's viscose fiber characteristice?

The basic composition of viscose fiber is cellulose (C6H10O5) no ordinary viscose fiber has a zigzag-shaped core structure in cross section, and the longitudinal direction is straight and grooved. The fiber-rich core-free structure has a circular cross section.

Viscose fiber has good hygroscopicity, and under normal atmospheric conditions, the moisture regain rate is about 13%. Significantly swelled after moisture absorption, the diameter increased by up to 50%, so the fabric feels hard after the water is launched, and the shrinkage rate is large.

The breaking strength of ordinary viscose fiber is smaller than that of cotton, which is about 1.6~2.7cN/dtex; the elongation at break is larger than that of cotton, which is 16%~22%; the wet strength drops more, about 50% of dry strength, wet stretch The increase is about 50%. The modulus is lower than that of cotton, and it is easily deformed under a small load, and the elastic recovery property is poor, so the fabric is easily elongated and the dimensional stability is poor. The strength of the rich fiber, especially the wet strength, is higher than that of the ordinary adhesive, the elongation at break is small, and the dimensional stability is good. Ordinary viscose has poor wear resistance, while rich fiber has improved.

The chemical composition of viscose fiber is similar to that of cotton, so it is more resistant to alkali than acid, but alkali and acid resistance are worse than cotton. Rich fiber has good alkali and acid resistance. Similarly, the viscose fiber has similar dyeing properties to cotton, and the dyeing chromatogram is complete and the dyeing performance is good. In addition, the thermal properties of viscose fiber are similar to those of cotton, and the density is close to cotton of 1.50~1.52g/cm3.

Although viscose fiber is artificial cellulose, its main raw material is chemical pulp, which is regenerated by separating natural cellulose through chemical reactions. During the reactions process, the filtration of viscose solution is the crucial factor affecting the spinning quality and finished viscose fiber products. So how to gain high quality viscose fiber in low consupmtion? Sintered metal(such as SS316L) fiber felt filter material from our Shenda Filtration can effective removal of contaminants from high viscosity viscose polymer and macromolecules from gel, thus ensure the cleanness of spinning dopes. We design and fabricate complete filtration solution for global viscose fiber manufacturers.
