  • What is the lifting performance of disperse dyes?

    2021-10-12

    ①The definition of lifting power:Lifting power is one of the important properties of disperse dyes. This characteristic indicates that when each dye is used for dyeing or printing, the amount of dye is gradually increased, and the degree of color depth on the fabric (or yarn) increases accordingly.

  • The effect of disperse dyeing?

    2021-07-27

    The thermal migration of disperse dyes is not the redistribution of dyes in the two phases of fiber and surface solvent under dry heat conditions, but its inherent physical characteristics, which also cause the color fastness and shade variation of polyester-containing fabrics to decrease during dry Read More

  • Why is the dispersion fastness poor?

    2021-07-23

    Disperse dyeing is mainly used for polyester fiber dyeing at high temperature and high pressure. Although the disperse dye molecules are small, it is not guaranteed that all the dye molecules enter the fiber during dyeing. Some disperse dyes will adhere to the fiber surface, resulting in poor fastne Read More

  • Dyeing of disperse dyes

    2021-07-23

    The influence of disperse dyeing The thermal migration of disperse dyes is not the redistribution of dyes in the two phases of fiber and surface solvent under dry heat conditions, but its inherent physical characteristics, which also cause the color fastness and shade variation of polyester-contain Read More

  • What is the reason for the decrease in fastness caused by thermal migration after disperse dyeing?

    2021-07-13

    Thermal migration is a redistribution phenomenon of disperse dyes in two-phase solvents. Therefore, all additives that can dissolve disperse dyes can produce thermal migration.The reason for the thermal migration phenomenon is that the auxiliary agent in the outer layer of the fiber dissolves the dy Read More

  • Why do color spots appear in disperse dyeing

    2021-07-02

    Causes of scattered dyeing spots and spots There are two kinds of color spots and spots produced by the high temperature and high pressure dyeing machine when dyeing polyester knitted fabrics:1. The color spots and spots caused by the condensation of dyes can be repaired with a repair agent or strip Read More
