  • Which dyeing temperature is suitable for Cold -rolled pile staining ?

    2023-04-14

    Cold -rolled pile staining, usually ethylene dyes. This is because the active base of the ethylene -type active dye is commonly used, which is very sensitive to alkali. In an alkaline bath, the reaction can be quickly disappeared, and the ethylene radon (-so2ch = CH2) with strong chemical activity c Read More
  • What will influence cationic dyes in dyeing

    2023-03-31

    The cationic dye has a large affinity for acrylic. When dyeing, it spreads slowly due to fast adsorption, which is prone to dyeing uneven phenomenon. Once the dyeing is incomplete, it is difficult to correct it by extending the dyeing time. When dyeing the cation dye, in order to obtain a uniform dy Read More
  • The basic process and dyeing method of dyeing

    2023-03-10

    According to the perspective of modern dyeing theory, the reason why dyes can be dyed in dyeing fiber have a certain degree of fastness on the fiber fabric, because the dye molecules and fiber molecules exist in various gravity, the principles and principles of dyes and various types of dyes The dye Read More
  • How to improve the wet friction for reactive dyes

    2023-02-24

    1. Select reactive dyes with less floating color after dyeingFloating color is the main reason for the unqualified damp friction of dark color fabrics.Active dye -dye dyes include dyes that have been adsorbed on the fiber without reaction to the fiber, partial hydrolyzed dyes, and ethylene cymbal dy Read More
  • What is the role of printed steaming

    2023-01-06

    After the textile is printed, in addition to the ice dye and soluble reduction dye, the general dye must be steamed.The purpose is to make the printed textiles complete the hygroscopic and warming of the fiber and color paste, the restoration of the accelerated dye and the dissolution of the fiber, Read More

    2022-12-16

    1. Unqualified color plasticityThe color fastness includes sun exposure, soap washing fastness, sweat staining fastness, friction fastness, sublimation fastness, ironing fastness, etc. These fastness is The dyeing process and external conditions are closely related. Therefore, whether the color fast Read More
  • What aspects are involved in dye processing

    2022-09-16

    1 Analysis of primary dyesThe original dye analysis mentioned here refers to the testing and analysis of the physical and chemical properties of the original dye for the needs of dye processing. After years of research, it is found that post-processing is by no means a simple physical process. Befor Read More
  • Why do blemishes occur

    2022-08-19

    Agglomeration of DyesDue to the direct collision of dye molecules, larger dye aggregates (or dye associations) are aggregated. These larger dye aggregates are deposited on the fabric during the dyeing process, resulting in color stains.When dyeing: the free dye molecules will recrystallize during th Read More
  • Why is reactive turquoise dip dyeing easy to produce color spots and stains?

    2022-04-29

    When the medium temperature reactive turquoise blue is dip-dyed, the reason why it is easy to produce color spots and stains is because the reactive turquoise blue has the defects of salt resistance and poor alkali dissolution stability. The medium-temperature active turquoise blue has good salt-dis Read More
  • Dye color theory

    2022-04-22

    The theory holds that the selective absorption of different light by a substance will present various colors, and the color of the substance is the complementary color of the light wave it absorbs. The same is true of dyes. The color of dyes is also the complementary color of the color of the light Read More

    2022-04-15

    Direct dyes refer to dyes that can be directly dissolved in water, have high directness to cellulose fibers, and do not need to use relevant chemical methods to color fibers and other materials. The principle of direct dyesDirect dyes have water-soluble groups such as sulfonic acid group (-SOH) or c Read More
