Synthetic Fiber: Weaving Beautiful World
Wallace Carothers (Wallace Hume Carothers) is a talented young chemist. In 1930, when he conducted polyester experiments, it was found that a molten polymer could stretch into filaments.
More importantly, even after cooling, the length of the fiber is several times longer than the original length.

The strength and elasticity are greatly improved.
With his efforts, polyamide 66 was born.
The polymer has high melting point and is not soluble in ordinary solvents. Because its structure and properties are closer to natural silk, the drawn fiber has the appearance and luster of silk, its abrasion resistance and intensity exceed that of any fiber at that time, and the raw material price is also cheaper. The US DuPont Co decided to develop and produce its products.
In October 27, 1938, DuPont Co officially announced the world's first kind.
Synthetic fiber
It was officially born and named polyamide 66 as nylon, nylon.
Nylon is a kind of synthetic fiber with broad prospects. It can be used for the production of elastic nylon stockings, gloves, hats and so on. It can also be blended with cotton and wool to form various soft products, such as satin quilt, nylon and so on.

In the synthetic fiber family, there are polyester, polyvinyl chloride, polypropylene, acrylic, vinylon and aramid fiber. They are widely used in various industries.
As we call "Dacron" polyester, it is widely used in clothing and bedding. Acrylic fiber, known as "artificial wool", is widely used in clothing and decoration fields. Its strength is 5~6 times that of steel wire, and its quality is only 1/5 aramid, which is used to make bulletproof coat and anti Cloak.
At present, synthetic fibers have been widely used in various aspects of the national economy, such as aerospace, electrical and mechanical, construction, automobile, household, clothing and sporting goods.
With the development of science and technology, many new synthetic fibers with special functions are constantly being developed, such as UV resistant fiber, negative ion fiber and intelligent fiber. Their application fields are also expanding, and the world will become more beautiful because of synthetic fibers.
