Water -soluble dyes generally contain water -soluble genes, such as sulfonic acid, carboxyl groups, etc. This type of dye can be dissolved in the aquatic solution.
There are many reasons for the color difference between samples, and the main reasons are the following aspects.① Be strict and accurate when playing samples. Sample samples are the key to directly affecting the large -scale production of the workshop. We must fully understand its importance and pay

The use of vulcanizing dyes in all cotton textiles is indeed economical, and the color fastness is also good, but erythema and red strips are often generated, which requires rework, which affects yield and cost. To solve this problem, you must pay attention to the following points: 1. Make good use
The main reason is that polyester fiber dyeing is high temperature and high pressure. Although the decentralized dye molecules are small, they cannot guarantee that the dyes molecules enter the fiber during dyeing. Some decentralized dyes will be attached to the fiber surface. The reducing cleaning
Choice of DyesBefore proofing, it must be clear what kind of cloth the proofing object is, and then choose the corresponding dye according to the type of cloth, such as dyeing polyester with disperse dyes or cationic dyes. Finally, the color of the dye is selected according to the color of the custo
The melting spinning is also known as the melt spinning. It refers to the heating and melting of the polymer polymer to the spinning melt with a specific viscosity. It becomes a melt filament flow, then cools and solidifies in the air or water, and then processes the wire by extending.
Improving the wet rubbing fastness of reactive dyed deep-colored fabrics is one of the important ways to improve the quality of textiles and overcome the export barriers of textiles.The main reasons for the poor wet rubbing fastness of textiles are the floating color transfer of water-soluble dyes a
This year, the business of solvent dye is not just burnt.Half of our markets in Europe, but from the beginning of the year, Europe's economy has been exhausted, such as the fierce shrinking of the automotive market, and the overall decline is rapid
There are many kinds of dyestuffs, but in terms of the physical form of their commodities, they can be divided into solid, liquid and slurry. It can be further divided into:Solid dyes—powder, granular, dust-free powder, block, flake, short column;Liquid dyes—water-soluble liquids and dispersions;Slu
1 Analysis of primary dyesThe original dye analysis mentioned here refers to the testing and analysis of the physical and chemical properties of the original dye for the needs of dye processing. After years of research, it is found that post-processing is by no means a simple physical process. Befor
