Background
Vinylon is a trade name for polyvinyl acetal fibers, also known as vinylon. The performance of the cotton is close to that of cotton, and the cotton is called synthetic cotton and is the variety with the highest hygroscopicity in the existing synthetic fibers. Vinylon was made in the 30 s by germany, but was not resistant to hot water, and was mainly used for surgical sutures. In 1939, the successful heat treatment and acetalization methods were studied to make the fibers with good hot water resistance. The raw materials for producing vinylon are easy to obtain, the manufacturing cost is low, the fiber strength is good, and the vinylon has various industrial purposes besides being used for clothing. But because the industrial production process is longer, the comprehensive performance of the fiber is inferior to that of terylene, chinlon and acrylon, and the annual output is smaller.
However, since vinylon fabrics cannot have good air permeability and flame retardancy, the development of vinylon fabrics is seriously hindered, and the vinylon fabrics are also deficient in toughness, so that vinylon fabrics with air permeability become hot spots for research and development of textile products, and among functional textile fabrics, air permeability fabrics are products with high difficulty and high technical content. The development of the better breathable vinylon fabric which meets the market demand has great significance.
