What is the meaning of vinylon fabric and vinylon fabric

Vinylon, also known as vinylon, is a brand name for polyvinyl alcohol fiber in China. It is a generic name for a synthetic fiber made from polyvinyl alcohol. Untreated polyvinyl alcohol fibers are soluble in water and can be treated with formaldehyde or titanium sulfate to increase their hot water resistance. The narrow definition of vinylon refers specifically to formaldehyde treated with polyvinyl alcohol.

Vinylon's main products are cutting short fibers and cutting yarns. The short fibers can be purely spun or blended with cotton, wool, viscose fibers, etc., and used for the production of woven or knitted fabrics such as coats, sweatshirts, cotton sweater trousers, sweatshirts, and the like. Vinylon cutting yarn can be used to make all kinds of taking products, storage tarpaulins, canvas, rubber conveyor belts or rickshaw tire cords, ropes, fishing nets, and packaging materials.

Vinylon fabric has the advantages of good hygroscopicity, strong abrasion resistance, high strength, good corrosion resistance, good chemical stability, and good light resistance.

The disadvantage of vinylon fabrics is that the hot water resistance is not good enough. If heated to 115°C in the wet state, it will shrink significantly. In boiling water, the strength will be reduced by 1/3. If boiled in water for 3~4h, the fabric may be deformed or partially dissolved. However, the heat resistance in the dry state is still relatively good. The softening point of vinylon is about 220~230°C. The elasticity of vinylon is poor, the fabric is easy to wrinkle, and the dyeing performance is also poor. Generally, neutral dyes and sulphur dyes are used for dyeing.
