Apr 24, 2018

Speaking of dyes, perhaps many people will think of the use of dyes in the clothes, most of the clothes we wear are made after dyeing, and the varieties of dyes are very many, such as direct dyes, acid dyes, leather dyes and so on. These dyes are not all the same, they are not the same. What are the reasons for the different local performance? For example, direct dyes are not suitable for cowboy clothing. Let's go and analyze it.

There are two main methods for dyed denim: first, yarn dyed and then woven. Secondly, the fabric is dyed directly. As for the former, the first is to use the reduction dye to dye it. The characteristic is the color is deep, the primary use of the dye is vulcanized. For the latter, the most important thing is to use paints for dyeing.

For denim fabric, it is necessary to wash, wash and grind the denim before making the denim. Especially in the deep processing, it is necessary to take part in the chemical agent, and some need to process the embroidery. If the direct dye is used, it will cause the performance of the denim to change. In addition, the direct dye will become more and more severe after some physical repercussions, especially when it meets the reductant, the molecular structure of the dye guessing will be damaged, and the color will eventually be lost. In general, if the jeans use the direct dye, then the quality of the jeans will be greatly reduced, the feeling that the person looks is lower at the level, but the direct dye is more suitable to be used in children's clothing.
