2.Synthetic Fiber
Synthetic fibers are made of synthetic polymer compounds. Common synthetic fibers are polyester, nylon, acrylic, chlorin, vinylon, spandex, polyolefin elastic yarn, etc.
1）Polyester
- Polyester’s scientific name is polyethylene terephthalate, referred to as polyester fiber. Polyester is the trade name of China. It is called “Dacolun”, “Telilun” and “Ditex” in foreign countries.
Polyester is the first in chemical fiber because of its easy availability of raw materials, excellent performance, wide application and rapid development.
The biggest characteristic of polyester is that the quality is stable, the strength and wear resistance are good, the fabric made by it is stiff and not easy to be deformed, and the heat resistance of polyester is also strong; it has good chemical stability, under normal temperature, Does not interact with weak acids, weak bases, or oxidants.
The disadvantage is that the hygroscopicity is extremely poor, and the fabric it is woven on is boring and airtight. In addition, due to the smooth surface of the fiber, the cohesive force between the fibers is poor, and the friction is often easy to fluff and form a ball.
2）Nylon
- Nylon is the trade name of China. Its scientific name is polyamide fiber; there are different varieties such as nylon-66, nylon-1010 and nylon-6. The name of nylon in foreign countries is also known as “nylon”, “Nylon”, “Kaplon”, “Amylon” and so on. Nylon is the world’s first synthetic fiber variety. Due to its excellent performance and abundant raw material resources, it is once the highest synthetic fiber production. Until 1970, due to the rapid development of polyester fiber, it was the second place in synthetic fiber.
The biggest feature of nylon is its high strength and good wear resistance.
The disadvantages of nylon are the same as that of polyester, which is poor in hygroscopicity and permeability. In a dry environment, nylon is prone to static electricity, and short-fiber fabrics are also prone to pilling and pilling. The heat resistance and light resistance of nylon are not good enough, and the ironing temperature should be controlled below 140 °C. In addition, the shape retention of nylon is poor, and the clothes made of it are not as thick as polyester and are easily deformed. But it can be attached to the body and is a good material for making all kinds of body shirts.
