What are the precautions for spinning polyester fibers in the forming process
2026-01-13Polyester fiber (polyester) spinning adopts melt spinning as the mainstream process, and some products use solution spinning. The forming process needs to be strictly controlled around the four core dimensions of melt quality, spinning temperature, stretching and shaping, and cooling and solidification. Specific precautions are as follows:

What are the core advantages of polylactic acid fiber
2025-12-23The core advantages of polylactic acid fiber are concentrated in two dimensions: environmental protection and practical performance for textile adaptation. It is different from traditional synthetic fibers such as polyester and nylon, and also has a core competitiveness that is superior to some natural fibers. The specific core advantages are summarized as follows:
-
What are the specific aspects of the chemical corrosion resistance of polyester fibers
2025-12-15The chemical corrosion resistance of polyester fiber (polyester) is due to its stable molecular structure and strong chemical inertness of ester bonds in the molecular chain. It exhibits good resistance to most acids, bases, salts, and organic solvents at room temperature, which is reflected in the following aspects:
-
What are the uses of polyester fibers in the non textile field
2025-12-08The raw material of polyester fiber, polyethylene terephthalate (PET), has the characteristics of high strength, wear resistance, and chemical corrosion resistance. Therefore, it is widely used in the non textile field, covering multiple industries such as packaging, industry, electronics, and construction. The specific uses are as follows:
-
What are the breakthroughs in high-performance polylactic acid fibers
2025-12-02The high-performance breakthrough of polylactic acid fibers mainly focuses on four directions: improving heat resistance, enhancing functional modification, optimizing mechanical properties, and innovating processing technology. Through molecular structure regulation, composite modification, and specialized equipment research and development, the shortcomings of poor heat resistance, insufficient

What are the components of composite spun fibers
2025-11-25The core component of composite spun fibers is two or more polymers (resins) with different properties. In some scenarios, a small amount of functional additives may be added, which are fused through composite spinning technology to achieve complementary properties.
-
What is the insulation principle of polyester fiber
2025-11-18The core of the insulation principle of polyester fiber is to lock in static air and reduce heat transfer, using its structural characteristics to hinder heat loss and achieve insulation effect. Core insulation mechanism 1. Storage of still air: Polyester fibers themselves have a low density, and a large number of tiny gaps will form between fibers or inside fibers (such as hollow polyester fibe
-
Who uses polylactic acid fiber more often
2025-11-10The core users of polylactic acid fiber (PLA fiber) are those who are concerned about environmental protection, pursue safety and comfort, or have special scenario needs, concentrated in the fields of textile, medical, packaging, and agriculture. The specific high-frequency users are as follows:
