Nylon cloth is mainly used for synthetic fibers. Its most outstanding advantage is that its wear resistance is higher than all other fibers, which is 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fibers to blended fabric can greatly improve its wear resistance. When stretched to 3-6%, the elastic recovery rate can reach100%; Can withstand tens of thousands of bends without breaking.
Extended data
Invention of nylon: DuPont actively promoted the implementation of this patent. In view of the widespread defects in silk stockings at that time, DuPont decided to put nylon fiber into the sock market first, and nylon stockings with wear resistance, heat resistance and chemical resistance were immediately sought after by consumers and were regarded as rare things to be snapped up. Nylon was also quickly used to manufacture military and civilian products, such as parachutes, aircraft tire cord fabrics and so on. Make it a valuable commodity in World War II.
The birth of nylon promoted the development of polymer research, laid the foundation of synthetic fiber industry and made textiles look brand-new.
However, W. carothers himself fell into severe depression, long-term work pressure, and was afraid that the research could not bring benefits to the company. His beloved sister died suddenly in a hotel room in Philadelphia on April 29, 1937, taking cyanide and committing suicide, only three weeks after the above patent application, at the age of 4 1.
He is an outstanding American chemist. He studied the structure of high molecular weight substances and the polymerization reaction that produced high molecular weight substances, which not only led to the invention of nylon and neoprene, but also promoted the rise and development of synthetic fibers.
