There are many differences between polyester fiber and cotton in raw material sources, performance characteristics, production and processing, and uses, as follows:
1. source of raw materials
Polyester fiber: it is a kind of synthetic fiber, and its main raw materials are fossil fuels such as oil and natural gas. Poly (ethylene terephthalate) (PET) was prepared from organic binary acids and diols through a series of chemical reactions through chemical synthesis, and then polyester fiber was formed through spinning and other processes.
Cotton: it is a kind of natural fiber, which comes from the seed coat of cotton plants in Malvaceae. Cotton is grown from cotton plants. After picking, ginning and other preliminary processing, cotton fibers for textile use are obtained.
2. performance characteristics
Polyester fiber: high strength, good wear resistance, not easy to damage; Good elasticity, close to wool, strong wrinkle resistance, not easy to deform; It is crisp, can be dried quickly after washing, and is not easy to shrink after washing; It has good chemical corrosion resistance and is stable to common acids, alkalis and other chemicals; The insulation is good, but the permeability is poor, and the moisture absorption is weak. When wearing it, it may feel stuffy and hot, and it is easy to generate static electricity.
Cotton: it has strong hygroscopicity, can absorb moisture in the air, and makes people feel soft and comfortable when touching the skin, without feeling stuffy and hot; Good dyeing performance, easy to dye various bright colors; The cotton fiber has an air layer in the middle, which can play a good role in heat insulation and warmth retention; The texture is soft and comfortable, but it has poor elasticity and is easy to wrinkle, and may shrink to a certain extent after washing.
3. production and processing
Polyester fiber: the production process includes many chemical processing links such as polymerization, spinning and molding. Firstly, the raw material is polymerized to produce PET polymer, then it is heated and melted, extruded through spinneret to form filament, and then made into polyester fiber through cooling, curing, stretching and other processes. The production process is complex, so it is necessary to strictly control the temperature, pressure, raw material ratio and other parameters.
Cotton: the processing of cotton is relatively simple. First, the cotton is picked, and then the cotton seed is removed through the ginning process to get lint. Next, the cotton fibers are combed into loose slivers through the processes of clearing and carding, and then the slivers are spun into cotton yarn through the spinning processes of drawing, roving and spinning, which can be used for subsequent processing such as weaving, printing and dyeing as required.
4. purpose
Polyester fiber: widely used in clothing, home textiles, industry and other fields. In terms of clothing, it is often used to make sportswear, outdoor clothing, functional clothing, etc., because it has good wear resistance and easy care; In the field of home textile, it can be used to make bedding, curtains, sofa covers, etc; In industry, it can be used to manufacture tire cord, rope, fishing net, geotextile, filter material, etc.
Cotton: mainly used in the textile industry, it is an important raw material for the production of all kinds of clothing, bedding, towels and other textiles. Because of its softness, comfort, good moisture absorption and other characteristics, it is especially suitable for making intimate clothing and home textile products. In addition, cotton can also be used in the medical field, such as making medical gauze, cotton ball, etc.
