عربى1. Characteristics of polyester fiber
Polyester fiber is a synthetic fiber obtained by polycondensing diols and dibasic acids to form polyester and then melt spinning. It has the following notable features:
Strong wear resistance: Polyester fiber is significantly more resistant to wear than natural fibers, making it an ideal choice for making durable clothing and household items.
Good wrinkle resistance: Its molecular structure is compact and not easy to deform. Even after repeated washing and wearing, it can still maintain a good shape.
Good elasticity: Polyester fiber has good elastic recovery ability and can quickly return to its original shape under the action of external force, thus maintaining the crispness of the clothing.
Easy to clean: Polyester fiber has excellent chemical resistance and good resistance to acids, alkalis and other chemicals, and is easy to clean and maintain.
Good insulation: Polyester fiber has low thermal conductivity and good warmth retention properties, making it suitable for making winter clothing and thermal insulation materials.
Diverse surface treatment: Through special processing technology, polyester fiber can present different appearance and feel, such as soft, smooth, plush, etc., to meet diverse market needs.
2. Production process of polyester fiber
The production process of polyester fiber mainly includes four steps: raw material preparation, polyester synthesis, melt spinning and post-processing:
Raw material preparation: Select high-quality diols (such as ethylene glycol) and dibasic acids (such as dimethyl terephthalate) as raw materials.
Polyester synthesis: Under the action of a catalyst, diols and dibasic acids are esterified to produce polyester.
Melt spinning: After the polyester is melted, the melt is extruded into filaments through a spinning machine, and then goes through processes such as cooling, stretching and shaping to form polyester fibers.
Post-processing: Dyeing, shaping, napping and other treatments are performed on polyester fibers to meet different market demands.
3. Application of polyester fiber in Berber Fleece fabric
Berber Fleece fabric is widely popular for its softness, warmth and durability, and polyester fiber is one of its key materials. In the production of Berber Fleece fabrics, polyester fibers can be processed through different processes, such as brushing and shearing, to create a unique plush feel and touch. The abrasion resistance and wrinkle resistance of polyester fiber also enable Berber Fleece fabric to maintain a good shape and appearance during long-term use.
4. Environmental protection and sustainable development of polyester fiber
With the enhancement of environmental awareness, the environmental protection and sustainable development of polyester fiber are also receiving increasing attention. The traditional polyester fiber production process generates a large amount of waste and consumes a lot of energy, which places a certain burden on the environment. In recent years, with the advancement of technology and the improvement of environmental awareness, more and more polyester fiber manufacturers have begun to adopt environmentally friendly raw materials and production processes, such as using recycled polyester fibers, bio-based polyester, etc., to reduce environmental impact. negative impact.
The recycling of polyester fiber is also an important way to achieve sustainable development. By recycling waste polyester fibers and using them to produce new polyester fibers after processing, we can effectively reduce resource waste and environmental pollution.
5. Future development trend of polyester fiber
With the advancement of technology and changes in the market, the future development trend of polyester fiber will show the following characteristics:
High performance: By improving the production process and raw material formula, the wear resistance, wrinkle resistance, elasticity and other properties of polyester fiber can be improved to meet higher-end market demands.
Functionalization: By adding functional additives or using special processes, polyester fibers can have special functions such as antibacterial, anti-mite, and anti-ultraviolet to meet the application needs of different fields.
Environmental protection: Continue to promote the research and development and application of environmentally friendly raw materials and production processes to reduce energy consumption and environmental pollution in the production process of polyester fibers.
Intelligence: Combined with advanced technologies such as the Internet of Things and big data, intelligent management of the polyester fiber production process can be achieved to improve production efficiency and product quality.
