Precautions and diffusion properties of the normal temperature and pressure jet dyeing machine
Dec 25, 2018

The normal temperature and pressure jet dyeing machine can effectively avoid the coloring, color stains, stains, and other defects caused by the improper operation and poor operation of the process, and the overflow dyeing machine should be used in the dyeing of high temperature and high pressure dyeing machines. Note the following:

1. Dye selection when dyeing, try to use a variety of diffuse and leveling dyes. When color matching, dyes with similar dyeing properties should be used.

2.Restore cleaning is an important part of removing floating color. After the reduction and cleaning, the color is slightly lighter. At the same time, the rubbing fastness and the light fastness are improved.

3. Prevention of tar spot The so-called tar spot is a viscous substance formed in the dyeing liquid. The price of the high temperature and high pressure overflow dyeing machine is mainly composed of a dye dispersant and a polyester oligomer. Polyester oligomer is a polycondensation of polyester. It will ooze from the fiber into the dye solution and adhere to the surface of the fiber during the long-term dyeing process at high temperature.

The measures for preventing tar spot at normal temperature and normal pressure jet overflow dyeing machine are as follows:

(1) Strengthen the fabric pretreatment.

(2) Improve the dye bath ratio.

(3) Application of high temperature and high pressure dispersant.

(4) Use high temperature drainage to prevent crystals from crystallization after cooling.

(5) Shorten the equipment cleaning cycle.
