Functional use / reactive dyes

Reactive dyes because of its matrix dyes, ligands and active groups, so that when used in the formation of a strong covalent bond with the fiber, and with a series of other cellulose fiber dyes can not match the characteristics of its established as a fiber The development and use of dye-based dye with the focus of the status, highlighted in the following four aspects:

(1) Reactive dyes are one of the best options for replacing dyes and other types of cellulose dyes such as sulfur dyes, ice dyes and vat dyes.

(2) Reactive dyes can achieve high levels of fastness, especially wet fastness, with economical dyeing processes and simple dyeing operations.

Reactive Dye Atlas

Reactive dyes dyeing method; reactive dyes cotton, the most commonly used dyeing method: dip method, in addition to rolling dyes. Dyeing method: dip method can be divided into one bath one step method, one bath two step method, two bath three kinds of dyeing method. A: one bath one step: is in the alkaline bath dyeing, that is, while dyeing in the fixing, this method is simple, short dyeing time, easy to operate, but due to adsorption and fixing at the same time, after fixing Dyes can no longer be spread, so leveling and poor dyeability. With the addition of alkaline conditions in the dyeing, dye dye dye stability, more hydrolysis. B: a bath two-step method: first in the neutral bath dyeing, when the dye on the dye close to the balance, in the dye bath by adding alkali agent, adjust the PH value to the fixed value of PH, (usually 11) And fiber to achieve covalent combination, to achieve the purpose of fixing. One bath two-step method is a more effective dyeing method in reactive dye dyeing method, it can not only get higher dyeing rate and fixation rate. And a good leveling effect, so cotton knitted fabric dyeing commonly used this method.
