Latest News and Updates on Textile Auxiliaries and Dyes

Disperse dyes are poured into water and then dispersed into fine particles. The particle size distribution is expanded according to the binomial formula, with an average value of 0.5 to 1 micron. The particle size of high-quality commercial dyes is very close, and there is a high percentage, which c

When pure polyester fabrics are dyed with disperse dyes, especially filament fabrics, they always look bright and white after dyeing. Increasing the dye concentration will not help, and the color fastness will be greatly reduced.There are two reasons for the low blackness:1. The cross-section of pol

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.

Apply softener to ensure good hand feeling.

Dyes are easy to aggregate, have poor solubility, poor compatibility, and are too sensitive to temperature and pH, which are prone to color mottling and chromatic aberration. For example, the active turquoise blue KN-R is easy to produce colored flowers.
