Since its invention, polyester staple fiber has achieved rapid development with its absolute advantages. Its quantity has accounted for 1/3 of the world's textile fiber and about half of China's textile fiber processing volume. It has become a leader in synthetic fibers and is today's ideal. Textile materials. Its superiority mainly depends on its specific macromolecular structure; it not only has a rigid benzene ring, but also has aliphatic chain links, which makes it not only melt-processable and easy to process into fibers, but also its macromolecules are sufficiently rigid , Give the fiber a high initial modulus. Polyester has good overall performance, high strength, good elasticity, and good processing performance. The fabric made of it is firm and not easy to deform. It does not need to be ironed after washing. It can be spun purely or blended or interwoven with various natural fibers. It is widely used Clothing, home textiles and technical textiles. In terms of clothing, polyester-cotton blended fabric can be used for shirts and bedding, and polyester filament can be used for outerwear, sportswear, and can also be used to produce natural fiber products such as wool, silk, and linen. Because polyester can be mass-produced, processing technology is continuously improved, and production costs are reduced, the prospects for polyester are bright. The dyeing defects of polyester have brought a lot of trouble to the production of polyester products, so we must have an understanding of polyester dyeing defects, such as color patterns, color points and color differences during polyester dyeing, and analyze the causes of these defects during polyester dyeing What are the preventive measures to control the defects in polyester dyeing and solve these defects in polyester dyeing to reduce the production troubles caused by polyester processing and products.
