Nylon 6 is a type of polymer material with characteristic structure amide bonds on the main chain of macromolecules, and its dyeing performance is similar to wool. It has excellent strength, abrasion resistance, soft hand feeling, light texture and other good wearing properties, and it occupies an i Read More

The color transfer of textiles is mainly due to two reasons: First, the dye has transferred, especially after the sample is wetted, the dye is more likely to transfer. This is also the reason why the wet rubbing color fastness is generally worse than the dry rubbing color fastness. It needs to be po Read More

The difference between organic solvent dyes and inorganic solvent dyesThe reason why we can see all kinds of colors in our lives is because we use some solvent dyes for dyeing, whether it is the clothes we wear, the brightly painted daily necessities or the buildings in various shades , We need to u Read More

Cause： When the medium-temperature reactive turquoise blue is dip dyed, it is easy to produce color spots and stains, because the reactive turquoise blue has the defects of poor salt resistance and alkali solubility stability. The meso-temperature reactive turquoise blue has good salt dissolution st Read More

Application of optical brightener in papermakingWith the improvement of people's material and cultural living standards, the development of science and technology and industrial production, the requirements for paper quality and quantity are getting higher and higher. In order to obtain high-quality Read More

What is source enzyme and its application? According to the different fiber processed, it is divided into protease and cellulase. Among them, proteases (such as alkaline protease 2709/209, neutral protease ZS724, 1398, etc.) are used to catalyze the hydrolysis of sericin on silk. Cellulase is used t Read More

Temperature effect and salt effect of direct dyeing(1) Temperature effectTemperature has different effects on the dyeing rate of direct dyesThe structure is relatively simple, easy to dissolve, low affinity to fibers, and high diffusion rate.The structure is relatively complex, difficult to dissolve Read More

El poliéster es tipo de resina plástica que se obtiene del petróleo a través de una sucesión de procesos químicos. Aunque existen muchas variantes posibles del poliéster, la más conocida es la termoplástica llamada PET (formada sintéticamente con etilenglicol y tereftalato de dimetilo). Como resultado de su polimerización se obtienen las fibras que luego se utilizan en prendas de vestir. A pesar de haber sido introducido en la industria hace menos de un siglo, hoy en día es uno de los más utilizados, especialmente en ropa técnica. Read More

ElasticitySpandex fiber has great elasticity. Under normal circumstances, it can be stretched to 4 to 7 times of its original length, and its recovery rate is almost 100% when stretched by 2 times, and its resilience rate is 95 when stretched by 500%. ~99%, which is unmatched by other fibers. Genera Read More

When dyeing, do you know the precautions for acid dyes?The biggest performance defect of acid dye dip dyeing nylon is its dependence on the pH value of the dyeing bath, that is, its dyeing rate and amount will change significantly with the fluctuation of the pH value of the dyeing bath. According to Read More

Performance defects of medium temperature reactive dyesThere are varying degrees of "uneven dyeing" in the process of dip dyeing with moderate temperature reactive dyes. The main performance is that it is easy to produce color stains or uneven color, and poor color fastness. This often results in re Read More
