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
