Abstract

The invention discloses a preparation method of self-adhesive polymer / disperse dye composite particle and its application in hot-melt dyeing of polyester. The preparation method comprises: (1) after mixing disperse dyes, dispersants, defoamers and water, grinding the disperse dyes into particles with a size between 100 and 1000 nm to form an aqueous dispersion of disperse dye particles; (2 ) Dissolving the emulsifier and dispersant in water to obtain a water phase solution; mixing the vinyl monomer and costabilizer to obtain an oil phase solution; mixing the water phase solution and the oil phase solution to obtain a monomer microsuspension; (3) The aqueous dispersion of disperse dye particles is mixed with the monomer microsuspension, sheared to obtain the monomer microsuspension containing disperse dyes, and the self-adhesive polymer / disperse dye composite particles are prepared through polymerization. The self-adhesive polymer / disperse dye composite particle prepared by the invention has good water dispersibility and strong adhesion to polyester fiber, can be applied to hot-melt dyeing of polyester, and can improve the dyeing efficiency and dyeing effect of the disperse dye.

Description

(1) Technical field [0001] The invention relates to a preparation method of a polymer / disperse dye composite particle and the application of the polymer / disperse dye composite particle in hot-melt dyeing of polyester. (2) Background technology [0002] Using polymer materials to coat disperse dyes, thereby changing the surface properties of disperse dyes, can improve the water dispersibility and application performance of disperse dyes [Coloration Technology, 2010, 121, 76-80; Journal of Applied Polymer Science, 2011, 121, 1616 -1621.]. At present, composite particles composed of disperse dyes and polymers have been used in the high-temperature and high-pressure dyeing processing of polyester. In order to adapt to the dyeing process, the materials used to coat disperse dyes are generally selected to be resistant to high temperatures, not easy to soften, and have high hardness and mechanical strength. of polymers. [0003] Hot-melt dyeing is a continuous polyester dyeing pr...
