Operation process of normal temperature and normal pressure jet overflow dyeing machine and measures to prevent tar spot
Feb 22, 2019

In the process of normal temperature and normal pressure jet overflow dyeing machine, when dyeing is selected, it is necessary to select the quality of diffusion and uniformity. In the process of color matching, the dye with similar dyeing performance should be selected.

The normal temperature and normal pressure jet overflow dyeing machine is reduced to some extent. The reduction cleaning is an important part of removing the floating color. After the reduction and cleaning, the color is slightly lighter. At the same time, both the rubbing fastness and the light fastness are improved.

The measures for preventing tar spots in normal temperature and atmospheric pressure jet overflow dyeing machines 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.
