JapanPolyester filament is made of polyester, which is an important variety of synthetic fibers. It is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG), and polyester hot-melt filament is obtained by esterification or transesterification and polycondensation. Fiber high polymer - polyethylene terephthalate (PET), fiber made by spinning and post-processing. The so-called polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a group.
First, the characteristics of polyester filament
Strength: The strength of the polyester fiber is nearly 1 time higher than cotton and 3 times higher than wool, so the polyester fabric is strong and durable.
Heat resistance: It can be used at -70℃~170℃, which is the best heat resistance and thermal stability among synthetic fibers.
Elasticity: The elasticity of polyester is close to that of wool, and its wrinkle resistance exceeds that of other fibers. The fabric does not wrinkle and has good shape retention.
Abrasion resistance: The abrasion resistance of polyester is second only to nylon and ranks second among synthetic fibers.
Water absorption: polyester has low water absorption and moisture regain and good insulation performance, but due to low water absorption, large static electricity generated by friction, and poor natural adsorption performance of dyes, polyester is generally dyed by high temperature and high pressure dyeing method.
Dyeability: Polyester itself lacks hydrophilic groups or dye acceptor parts, so polyester has poor dyeability. It can be dyed with disperse dyes or non-ionic dyes, but the dyeing conditions are relatively harsh.
Second, the use of polyester filament
Polyester is used as a clothing fiber, and its fabrics are wrinkle-free and iron-free after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc., and is widely used in various clothing and decorative materials. Polyester can be used for conveyor belts, tents, canvas, cables, fishing nets, etc. in industry, especially polyester cord used for tires, which is close to nylon in performance. Polyester can also be used for electrical insulating materials, acid-resistant filter cloth, medical industrial cloth, etc. Synthetic fibers have been widely used in various fields of the national economy due to their high strength, wear resistance, acid resistance, alkali resistance, high temperature resistance, light weight, warmth retention, good electrical insulation and resistance to mildew.
3. Polyester filament and chemical staple fiber
Textile fibers are divided into natural fibers and chemical fibers. Natural fibers are mainly silk, wool, cotton, and hemp. Chemical fibers are further divided into synthetic fibers and man-made fibers.
Then compare polyester filament and acetate filament, because the two are equal, so they are classified later, polyester is synthetic acetate and artificial.
4. Polyester filament and staple fiber
Polyester (polyethylene terephthalate, PET) is polymerized from PTA and MEG. PET is in the shape of rice grains and has various varieties. 75% of polyester is used for chemical fiber, and the production of polyester short fiber is made of polyester staple fiber and polyester filament according to the requirements of the textile industry. Polyester fiber is divided into two types: filament and short fiber. The so-called polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a group. Polyester staple fibers are short fibers of several centimeters to ten centimeters.
Five, the characteristics and uses of polyester fiber
Strength: Polyester fibers are nearly 1 times stronger than cotton and 3 times stronger than wool, so polyester fabrics are strong and durable.
Heat resistance: It can be used at -70℃~170℃, which is the best heat resistance and thermal stability among synthetic fibers.
Elasticity: The elasticity of polyester is close to that of wool, and its wrinkle resistance exceeds that of other fibers. The fabric does not wrinkle and has good running properties.
Abrasion resistance: The abrasion resistance of polyester is second only to nylon and ranks second among synthetic fibers.
Water absorption: polyester has low water absorption and moisture regain and good insulation performance, but due to low water absorption, static electricity generated by friction is large, and dyeing performance is poor.
