The domestic papermaking dyes market has two categories: solid and liquid dyes.

The dyeing process of solid dyes adopts the intermittent method, which is added at the beater or mixing tank.

This method of adding is easy to produce color spots.

Liquid dyes can be continuously added to the high-level tank or in front of the slurry pump with a metering pump, which can effectively solve the above-mentioned paper problems and has the following advantages: using liquid dyes can improve the color fastness of the finished product. The fastness standard of liquid dyes is higher than that of solid direct dyes; the continuous addition method has the advantages of flexible adjustment and low loss, which overcomes the shortcomings of the traditional slurry pool type of long addition time and slow hue adjustment; the dyes can be switched by adjusting the flow rate of the metering pump quickly and reduce the debugging time, so that the hue of the product remains stable.

Cangzhou Xinchen Weiye Chemical Co., Ltd is producing both solid paper dyes and liquid paper dyes.

Our solid paper dyes include basic dyes, acid dyes and direct dyes. Liqud paper dyes include colors of black, yellow, blue, red, pink red etc. Welcome your inquiry.
