  • Dyeing Methods with Commonly Used Dyes


    Direct dye dyeingDirect dyes can be used for dyeing various cotton and viscose products. When dyeing, first wet the fabric with water, add it to the dye solution, heat it to 95°C, add neutral salt to promote dyeing, and dye it for 60 minutes. Wash with water after dyeing, and if necessary, add color Read More

    Medium temperature reactive dyesMedium-temperature reactive dye exhaust dyeing basically adopts conventional dyeing process. In fact, the dyeing properties of commonly used medium-temperature reactive dyes are not exactly the same, and there are three types.First typeThe performance characteristics Read More
  • Disperse Dyes Tips (Part 3)


    What is the fastness of disperse dyes?The dyeing fastness of disperse dyes is mainly the fastness to sunlight, sublimation, friction and washing. Particularly important among them are the light fastness in application performance and the sublimation fastness in post-processing. Others, such as wash Read More
  • Disperse Dyes Tips (Part 2)


    The hot-melt pad dyeing process is suitable for continuous dyeing of polyester/cotton blended fabrics. Its dyeing principle is also a type of high-temperature dyeing. The difference from high-temperature and high-pressure dyeing is that the melting temperature is high (180℃-220℃) and the time is short. (90 seconds). Read More

  • Disperse Dye Properties and Testing


    Disperse dyes are a type of dye with smaller molecules (molecular weight 200-500) and relatively simple structure. It does not contain strong hydrophilic groups such as sulfonic acid group so3- and carboxyl COOH. It only contains some weak polar groups such as carboxyl groups, amino groups, and nitro groups, and is a non-ionic dye with very low water activity. Read More
  • 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. Read More
  • 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
