  • How to improve the color fastness of reactive dyes?

    2021-08-02

    How to improve the color fastness of reactive dyesReactive dyes dye cellulose fibers to form chemical bonds with the fibers in the form of covalent bonds. Therefore, theoretically, the covalent bond between the dye and the fiber can give the dyed fabric excellent dye fastness. But in fact, its dyed Read More
  • 10 mistakes often made with reactive dyes!

    2021-07-16

    10 mistakes often made with reactive dyes!1. Why is it required to use a small amount of cold water to adjust the slurry and the temperature of the compound should not be too high?(1) Use a small amount of cold water to adjust the slurry first. The purpose is to make the dye easy to fully wet out. I Read More
  • Dyeing of cotton knitted fabric with reactive dyes

    2021-06-25

    Dyeing of cotton knitted fabric with reactive dyes1. The characteristics of reactive dyes1. Reactive dyes are soluble in water and contain active genes in the molecular structure. Under certain conditions, they can covalently bond with the hydroxyl groups on cellulose fibers.2. Reactive dyes have br Read More
  • Performance defects of medium temperature reactive dyes

    2021-05-14

    Performance defects of medium temperature reactive dyesThere are varying degrees of "uneven dyeing" in the process of dip dyeing with moderate temperature reactive dyes. The main performance is that it is easy to produce color stains or uneven color, and poor color fastness. This often results in re Read More
  • The structure of reactive dye molecules can affect wet rubbing fastness

    2021-02-15

    The structure of reactive dye molecules can affect wet rubbing fastnessl. Water solubility of dyes  The more water-soluble groups contained on the reactive dye molecule, the more favorable it is for the dissolution and uptake of the dye during the dyeing process, and of course the washing of floatin Read More
  • What are the characteristics of reactive dyes?

    2021-02-12

    What are the characteristics of reactive dyes?What we often call reactive dyes is also called reactive dyes. It is a type of dyes that react with fibers during dyeing. Reactive dyes are a new type of dyes, including two main components: the parent dye and the reactive group. , The group that can rea Read More
  • Level dyeing problem of reactive dyes

    2021-02-10

    Level dyeing problem of reactive dyesWhen reactive dyes are dyed, special bath softeners have been used to prevent rope creases or to promote dye penetration.Since reactive dyes are water-soluble, anionic levelling agents are generally not used. However, some reactive dyes have low solubility in alk Read More
  • The solution degree of reactive dyes is related to alkaline agents

    2021-02-08

    The solution degree of reactive dyes is related to alkaline agentsWhen the alkali agent is added, the β-ethylsulfone sulfate of the reactive dye will undergo an elimination reaction to form its real vinyl sulfone, which is very soluble in genes. Since the elimination reaction requires very few alkal Read More
