Latest News and Updates on Textile Auxiliaries and Dyes

Why does the fastness of qualified fabrics deteriorate after being shipped to customers?The thermal migration of disperse dyes is an inherent physical property of disperse dyes. Thermal migration is common regardless of the type of disperse dyes, but the molecular structure is different and the degr Read More

Common dye stripping and stripping processDye stripping, also known as stripping, generally uses chemical reactions to destroy the combination of dyes on fibers and fibers, destroy the dye structure on fibers, so that the dye strips off the fibers and cannot color.Commonly used color stripping agent Read More

In the textile printing and dyeing industry, reactive dyes are widely used in dyeing and printing of cotton, linen, viscose and other fibers with the advantages of complete color spectrum, bright colors, simple operation and moderate price. However, poor light fastness has always been a technical shortcoming that reactive dyes cannot avoid, especially in outdoor textiles, curtains, household goods, sportswear and other applications with high light requirements.

Basic knowledge of paint dyeingPaint dyeing is to make the paint into a dispersion liquid, and make the fabric or yarn evenly carry the liquid through padding or dipping. With the help of the adhesive, a transparent and tough resin film is formed on the fabric or yarn, so that the paint is mechanica Read More

Why do spandex fabrics need to be pre setting? The maximum temperature cannot exceed 195C Read More

Acid dye dissolution methodAcid dyes usually contain hydrophilic groups such as sulfonic acid groups (-SO₃H). In theory, they are easily soluble in water, but in some cases, they may be difficult to dissolve (such as high water hardness, pH mismatch or dye structure differences). The following are s Read More

Solvent dye dissolution methodSolvent dyes are a type of non-ionic dyes. Their molecular structure usually does not contain strong hydrophilic groups (such as sulfonic acid groups or carboxylic acid groups), so they are insoluble in water, but easily soluble in organic solvents or non-polar media (s Read More

The Application of Sodium hydrosulfiteSodium hydrosulfite, commonly known as "insurance powder" in the industry, plays a crucial role in the textile sector.In the process of textile dyeing and printing, insurance powder is widely used as a reducing agent. It helps to modify and improve the colorfast Read More

Comparison between liquid disperse dyes and ordinary disperse dyesIn the field of dyeing polyester textiles, disperse dyes are irreplaceable core materials. In recent years, with the tightening of environmental protection regulations and the popularization of intelligent manufacturing technology, li Read More

Disperse printing application and problem solvingDisperse printing is an efficient dyeing process for synthetic fibers such as polyester, especially suitable for textiles with bright colors and complex patterns. The process is based on disperse dyes and combines heat transfer, high-temperature fixat Read More
