1. It is easier to dye nylon with disperse dyes using alkali agents to reduce the color, but the shade changes greatly, and the darkening is serious.2. For dyeing nylon with neutral dyes, soda ash treatment has almost no color reduction ability, and the shade changes, caustic soda has the color redu

Nylon 6 is a type of polymer material with characteristic structure amide bonds on the main chain of macromolecules, and its dyeing performance is similar to wool. It has excellent strength, abrasion resistance, soft hand feeling, light texture and other good wearing properties, and it occupies an i

When dyeing, do you know the precautions for acid dyes?The biggest performance defect of acid dye dip dyeing nylon is its dependence on the pH value of the dyeing bath, that is, its dyeing rate and amount will change significantly with the fluctuation of the pH value of the dyeing bath. According to

What is acid dye and what is the function of acid dye?The biggest performance defect of acid dye dip dyeing nylon is its dependence on the pH value of the dyeing bath, that is, its dyeing rate and amount will change significantly with the fluctuation of the pH value of the dyeing bath.

What matters should be paid attention to when acid dyes are fixed?Nowadays, acid dyes have been widely used in the dyeing of fabrics and are often used by people. However, the dyes usually have poor color fastness. Therefore, some users are fixing the dyes to meet the standard, but we need to pay at

Classification and dyeing principle of acid dyesAcid dyes are a type of water-soluble dyes with acidic groups in the structure, which are dyed in acidic media. Most acid dyes contain sodium sulfonate, which is soluble in water, bright in color and complete chromatogram. Acid dyes are water-soluble a

Nylon (nylon) is a hydrophobic fiber with amino and carboxyl groups on the fiber. As a basic material, it has a wide range of applications, especially in the textile industry. Nylon can be dyed with disperse dyes, acid dyes, especially weak acid dyes. Its dyeing has the characteristics of fast dyeing rate and high exhaustion rate. However, due to the different spinning process specifications, the fiber structure is very different, which leads to large differences in dyeing performance and easy to produce color differences.

Acid dyes are a type of water-soluble dyes with acidic groups in the structure, which are dyed in an acid medium. Most acid dyes contain sodium sulfonate, which is soluble in water, bright in color and complete chromatogram. It is mainly used for dyeing wool, silk and nylon, but also for leather, paper, ink, etc. Generally no tinting power to cellulose fibers.
