The low-temperature water-soluble fiber is taken PVA as raw material and adopted a gel spinning technique with the following features:
1. Low water soluble temperature. It leaves no residue when dissolves in water at 20-60 ℃. The Sodium sulfide method can only produce ordinary fibers soluble in a high temperature of 80 ° C or higher.
2. Suitable for textile processing due to its high fiber strength, round fiber cross section, good dimensional stability, moderate linear density and the elongation.
3. Good resistance to insects and mildew, good resistance to light, much lower strength loss than other fibers on long exposure to sunlight.
4. Non-toxic and harmless to human and environment. The absence of sodium sulfide leads to free dust hazard during spinning process.
