Due to the deteriorating global environment in which human beings are living, countries around the world have taken environmental protection to an extremely important position, and the printing and dyeing and post-treatment of various textile materials is a great source of pollution. Therefore, the coloring of the melt in the fiber is The trend of spinning, first, the use of cationic raw materials, and dyes due to the action of ions to make dyeing easier, reduce pollution, the second is to directly add a variety of masterbatch, so that the fiber is processed to color, reduce the dyeing process, color fast It is also highly used and is widely used in various fabrics.

The raw material of PBT fiber is butylene terephthalate. Because of the increase of -CH2-CH2- molecular chain in the molecular chain

High shrinkage fibers are fibers that have a particularly high shrinkage after heating. The shrinkage of ordinary polyester after heating is only 10%, while the shrinkage of high shrinkage polyester after heating is as high as 50%. After the fabric is heat treated, the fabric is particularly dense and full due to fiber shrinkage. If the part of the fabric is made of high-shrinkage fibers, a pattern with a strong three-dimensional effect such as seersucker or jacquard will appear after heat shrinkage. A high-shrinkage fiber is used to make a pile fabric of chemical fiber velveteen and corduroy. When the base fabric is contracted by heat, the pile can be made denser. Blended or interwoven with pure polyester high shrinkage fiber and conventional pure polyester fiber, the fabric can be obtained by heating and setting, and various corrugated pure polyester fabrics can be obtained. Fine-knit polyester high-shrinkage filaments can be used to make suede and silk.
