Dyeing Process Of Polyester Yarn


      In the dyeing of polyester wool fabric, there are two difficulties of disperse dyes on wool stain and high temperature dyeing to wool damage. The dyeing process of cationic modified polyester wool fabric is analyzed by using cationic modified polyester instead of polyester in traditional polyester fabric, that is, one bath method and two Bath method Polyester Yarn

     The dyeing color fastness and wool damage were tested, and the main factors affecting the dyed shade of the fabric were expounded. The results show that the method of cationic modified polyester instead of polyester in traditional polyester fabric can solve the dyeing problem of traditional polyester fabric.Polyester Yarn

      Polyester fabric at the same time both polyester and wool excellent properties, such as moisture absorption, good thermal insulation, not easy to stain, good mechanical strength, wear-resistant, easy to mildew, chemical stability and so on. However, there are two major problems in the dyeing of polyester-wool textiles: One is the color of disperse dyes on wool, and the other is the damage of high temperature dyeing to wool. Polyester Yarn

     The color of the wool dyed by disperse dyes causes the decrease of the fastness and the fastness of the wet treatment of the polyester fabric, and makes the color fading, the difficulty of the color matching and the dyeing reproducibility worse.

     In the traditional polyester wool fabric, the cationic modified polyester instead of polyester, has a certain advantage: cationic modified polyester dyeing temperature is low, can overcome the shortcomings of conventional polyester is not easy to dye, on the high dyeing rate, the relative reduction of dyes in wool stained, easy to clean, wet treatment fastness, energy saving, bright color after dyeing.Polyester Yarn

     Reasonable selection of dyes is the basis to ensure the process of execution. Cation-Modified polyester can be cationic dye or distributed SD-type cationic dye (SD-type equivalent to the Japanese-produced Ed type, this kind of dye is the compound of the cationic dye and the sealant with anion, which is dispersed in the bath, and is dyed by a new type of cationic dye.Polyester Yarn
