What is polyester? What is the use of polyester yarn?
Polyester yarn refers to yarns spun from polyester, which is the fiber made of a class of polymers through spinning. At present, polyester mostly refers to the fibers produced with ethyl phthalate as the raw material. According to the English name of their raw materials, "PET" fibers are abbreviated. It is commonly known as dacron in our country. Usually the so-called "yarn", in fact, refers to the "yarn" and "thread" collectively, in the clothing material science is defined as follows: "yarn" is many short fibers or filament arranged into a approximately parallel state, and along the axial rotation of years, composed of a certain strength and linear density of slender objects; And "thread" is made up of two or more single yarn strands. Yarn is cotton, wool, hemp, chemical fibers elongated and viscose spun into thin strands (usually used as raw materials for weaving), and then cotton, hemp, silk, wool and other thin strands of thin strands, called thread.
The use of polyester yarn, polyester has a wide range of uses, a large number of clothing and industrial products. Flame retardant polyester has a wide range of applications due to its flame retardant property. In addition to playing an irreplaceable role in industrial textiles, architectural interior decoration and transportation interior decoration, it also plays a lot of roles in the field of protective clothing. According to the national standard of flame-retardant protective clothing, departments of metallurgy, forestry, chemical industry, petroleum and fire protection should use flame-retardant protective clothing. In China, the number of people who should use flame retardant protective clothing is more than one million, and the market potential of flame retardant protective clothing is huge. In addition to pure flame retardant polyester, according to the special requirements of users, the production of flame retardant, waterproof, oil repellent, antistatic and other multifunctional series products. If the flame retardant polyester fabric waterproof, oil repellent finishing, can improve the function of flame retardant clothing; The antistatic flame retardant fabric is produced by interweaving flame retardant polyester with conductive fiber. High performance flame retardant fabric can be produced by blending flame retardant fiber and high performance fiber. Flame retardant fiber blended with cotton, viscose and other fibers.
The advantages of polyester yarn, made of ordinary polyester filament fabric, its clothing performance has the advantages of good strength, smooth and crisp, easy to wash and dry, but there are some shortcomings such as hard hand feeling, poor touch, luster is not soft, air permeability, moisture absorption and so on. If compared with the real silk fabric, the gap is larger, so first in the structure of silk silk, to its poor performance shortcomings.
