Latest News and Updates on Textile Auxiliaries and Dyes

Sulfur dye has a history of more than 100 years since its birth. The first sulfur dye was made by Croissant and Bretonniere in 1873. They will contain organic fibers, such as wood chips, bran, scrap cotton and waste. Paper and other sulfide and polysulfonal alkali are obtained. Read More

There are two main methods of fabric printing and dyeing. One is traditional coating printing and dyeing, and the other is active printing and dyeing relative to coating printing.Active printing and dyeing is a dye under certain conditions, the active genes of dyes are combined with fiber molecules, Read More

1. According to the analysis of textile materials, general chemical fabrics are better than the moisture -resistant friction color of natural fabrics such as cotton, and thin fabrics are better than heavy fabrics. Therefore, during the processing of textile fabrics, the processing of each process sh Read More

The three -color lace elastic fabric developed by the four types of fiber -developed fiber development of an artificial silk, nylon, modified polyester filament, and Laica. According to the dyeing performance and characteristics of the fiber, the dyeing process includes water washing oil. Read More

"Leica" is the transliteration of English words lycra. As a kind of spandex elastic fiber, an embedded molecular chain segment polymethyl ester consisting of flexible chain segments and rigid chain segments. It was successfully studied by Bayer in Germany in 1937. It was produced in 1959 DuPont. Read More

level-dyeing propertyThe dye is greatly collaborated on acrylic. The high -dyeing rate has a tight structure, poor dye diffusion, and poor dyeing; T TG, rapid upper dyeing rate measures:1. Slow the speed of the upper dyeing; the final dyeing temperature is high, and t Read More

This article explains the principle of acrylic fiber dyeing. The description and application of important parameters in the process of dyeing, focusing on the accumulation of practical results, and providing valuable wealth for promoting acrylic fiber dyeing technology. Acrylic fiber dyeing mechanis Read More

The Effect Of Water Quality On Textile Printing And Dyeing1.HARDNESSIt is generally accepted that a hardness of less than 500ppm has no effect on textile dyeing, and 200ppm is already very good quality water.The key is the content of metal ions, especially iron ions, which can lead to changes in col Read More

In the process of photochemical changes, the color system of the dye molecules changes or is damaged, and the color change or fading will occur. In the field of textiles, the light resistance of dyes is represented by daily sun exposure, or it is also called optical resistance.Due to the different i Read More

1. The sun-light fastness is generally determined by the dye structure and type. For fibrin fabrics, the order of dyes from high to low in the sun is: restore (Shilin) Generally, the sunlight accuracy of some high -day exposure accuracy may also be better than Shilin.2. Activated dye commonly used t Read More

Dyeing Procedure of Disperse DyesHigh temperature high pressure dyeingHigh temperature high pressure dyeing is carried out using a closed type dyeing machines such as cheese, beam, jet, jig or liquor flow type according to the form of the material.General dyeing conditions are as follows:-About 1-2g Read More

In order to eliminate the yellow color tone that many products do not want, and improve the appearance of the product, there are usually three methods, chemical bleaching, blue and fluorescent white. Chemical bleaching is the oxidation of yellow substances through oxidation to fade it into white pro Read More
