  • Basic knowledge about vat dyes


    Vat dyes are insoluble in water and cannot be used to dye fabrics directly. When dyeing, it is necessary to use insurance powder in an alkaline solution to reduce the leuco body to a water-soluble leuco body, so that it can be adsorbed by the fiber, and then oxidized and developed by air, etc., to convert the leuco body into the original dye and dye it on the fiber.

  • Notes on Reactive Dye Dyeing Process


    Reactive dyes are a type of dye that react chemically with fibers during dyeing. This type of dye molecules contains groups that can chemically react with fibers. During dyeing, the dyes react with the fibers and form a covalent bond between the two to form a whole, which improves the washing and rubbing fastness. Reactive dyes are a new type of dye. In 1956, the UK first produced the Procion brand of reactive dyes. Reactive dye molecules include two main components: parent dye and reactive group. The group that can react with fiber is called reactive group. Read More
  • The Guide to Cotton Dye: the Best Dye and Practices!


    In the textile industry, different fabrics are dyed with different dyes. Cotton, one of the most common fabrics, is the best choice for dyeing because of its high water absorbency. The purpose of this article is to introduce the selection and process of cotton dyeing, and to answer questions that are widely used in daily life and in the textile industry. Read More
  • What happens if the heating/cooling speed is too fast during dyeing?


    Dyeing on an overflow machine, heating and cooling will directly affect the shrinkage of the fiber, resulting in a fold. For thermoplastic fibers such as nylon, once the fold is formed, it will be irreversible. Therefore, when dyeing, special attention should be paid to the need to slowly raise/lowe Read More
  • What is the reason for the color not conforming to the standard sample due to the poor control of the dyeing process conditions and operation?


    a) The semi-products before dyeing do not meet the requirements. If the dyed semi-finished product has insufficient mercerization, the mercerization will be alkali-colored, which will change the shade. For example, after sulfide dyeing, the cloth surface will be red and not black.b) Hard water is us Read More
  • What is suede and the difficulty of dyeing process?


    What is suede and the difficulty of dyeing processNatural suede originally refers to animal suede leather, which is very similar to deer in length, but the suede leather is not the same as the suede usually seen, and there is no short and dense fluff.This is because the skin and hair of the animal m Read More
  • What is the aggregation of dyes?


    Due to the direct collision of dye molecules, they aggregate into larger dye aggregates (or dye associations). These larger dye aggregates are deposited on the fabric during the dyeing process, causing color stains.When dyeing:The free dye molecules will recrystallize during the heating (or cooling) Read More
