HT Fine Textile Chemical Auxiliary Agent

Textile after spinning, dyeing and finishing, and clothing , there is generally one more process washing treatment, in order to achieve decontamination, prevent shrink, add flexibility, remove hair, or some other special visual effects, so that the comprehensive performance of clothing more closer to the normal, and with natural color. And in the process of washing, garment washing chemicals with proper use can make things easier and make better performance. According to the purpose of washing, it can be divided into the following types of garment washing: Wash shrinkage When the shrinkage of the fabric is excessive, a piece of cloth should be washed before making the garment, and the shrinkage rate of the warp and weft will be measured, and the size of the garment will be reduced to the size of the garment. After the sample is made, the washing test will meet the standard. These clothes are washed in water. And the size of the shrinkage must be consistent with the test s...

Whiteness and poor hair efficiency problems The poor whiteness includes the impure of whiteness, uneven whiteness, and wool effect less than 200px within 30 minutes, which is related to the quality of knitted fabric, such as lower-grade cotton content prone to cause poor whiteness, and of course, the most important is the process formulation and selection of textile auxiliaries, here to introduce some processing attentions: (1) the amount of H2O2 and NaOH must be sufficient: H2O2 not only plays a role of bleaching in pretreatment of textile fabric , but also has the function of detoying (including the cottonseed shell), the H2O2 quantity is insufficient (including decompose too fast), the whiteness cannot be guaranteed.  NaOH not only provides the base (pH) needed for H2O2 bleaching, but also works with the refined agent to maximize the clutter. The NaOH quantity is insufficient, and the miscellaneous is poor, and the wool effect cannot meet the requirements first. Of co...

Advanced dyeing and finishing technology: Detailed common quality problems and selection of textile auxiliary Here we mainly discuss on the influence of  textile auxiliary : The quality of  pretreatment (scouring and bleaching)  is related to not only effect on the quality of the end product, but also, as a semi-product, has effect on the quality of the dyeing, printing and finishing. Some experts think that 70% of the unqualified products is caused by improper pretreatment. And in a sense, it may be true. Though the result of dyeing and finishing is still related with the quality of the fabric, the equipment, the operation, the processing technology, the dye and the auxiliary. Now, we focus on the the auxiliary. There are many different kinds of problems related to  textile auxiliaries , here in this article, we mainly talk about three common quality problems of pretreatment and the choose of the auxiliary. 1.  The unsatisfying whiteness and capil...
