Disperse dyes are a type of dye with smaller molecules (molecular weight 200-500) and relatively simple structure. It does not contain strong hydrophilic groups such as sulfonic acid group so3- and carboxyl COOH. It only contains some weak polar groups such as carboxyl groups, amino groups, and nitro groups, and is a non-ionic dye with very low water activity. Read More

In the textile industry, different fabrics are dyed with different dyes. Cotton, one of the most common fabrics, is the best choice for dyeing because of its high water absorbency. The purpose of this article is to introduce the selection and process of cotton dyeing, and to answer questions that are widely used in daily life and in the textile industry. Read More

Polyester FibersPolyester fiber, commonly known as "polyester", is a synthetic fiber made from chemical polycondensation of organic dibasic acids and glycols. It is a kind of polymer compound and a synthetic fiber with high strength, high modulus and low water absorption.Therefore, traditional water-soluble dyes such as direct, acid, and reactive dyes cannot be adsorbed to this hydrophobic fiber, and therefore cannot be dyed.

Acid dyes refer to the acid group in the dye molecules, also known as anion dye, which can be combined with amino groups in protein fiber molecules with ion bonds and applicable under acidic, weak acids or neutral conditions. Mainly nitrogen and ， structures, a few are aromatum methane structures. Acid Dye Introduction and Different Items, This article show the difference between different dyes and show the benefirness of acid dyes. Read More

Agglomeration in the dyeing of disperse dyes will lead to problems such as color spots, stains, and cylinder contamination. How to prevent the agglomeration of disperse dyes in dyeing, please see the following: 1. The principle of dye aggregationGenerally, the particle diameter of disperse dye is ab Read More

The emergence of disperse dye -alkaline dyeing:When decentralized dye dyeing conventional polyester, the general dyeing bath is generally controlled (pH value is 5-6). Due to dyeing under acidic conditions, most of the scattered dye color light is the purest and high -dye rate. However, polyester si Read More
