Problems solved by technology

However, the microcapsules do not have sufficient mechanical strength and hardness, and are prone to breakage due to friction and extrusion of fabrics under high temperature and high pressure conditions. At the same time, the core-encapsulation rate of the disperse dye microcapsules is low
[0005] In the Chinese patent application CN102453351A, the inventor prepared a microcapsule capable of rapidly releasing dyes with disperse dyes, a system regulator, distilled water, a melamine resin prepolymer and a diffusing agent, but the microcapsule needs to add a system regulator, Although it can play a role in stabilizing the core material droplets, if it also has residual problems, it increases the cost of subsequent processes

Abstract

The invention belongs to the field of textile dyeing and printing, and particularly relates to a dispersive dye microcapsule. The dispersive dye microcapsule is prepared from the following components in parts by weight: dispersive dye, wall material and dispersant according to a weight ratio of 1:(2 to 8):(0.6 to 2); the wall material is prepared from polyurethane and bacterial cellulose according to a weight ratio of 1:(0.3 to 0.9). The dispersive dye microcapsule has the advantages that the dispersive dye microcapsule can be quantitatively fed, the labor intensity is decreased, the enough hardness and mechanical strength are realized, the core coating rate is high, the preparation cost is low, the operation is simple and convenient, the pollution is little, and the dispersive dye microcapsule is suitable for being widely popularized and applied.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a disperse dye microcapsule and a preparation method thereof. Background technique [0002] Microencapsulation technology refers to the technology of embedding solids, liquids or gases in tiny and sealed capsules so that they can be released at a controlled rate only under specific conditions. Among them, the substance to be embedded is called the core material, including flavors and fragrances, acidulants, sweeteners, pigments, lipids, vitamins, minerals, enzymes, microorganisms, gases and other various feed additives; the embedding core material realizes The microencapsulated material is called wall material. Microcapsules can effectively reduce the reaction of active substances to external environmental factors (such as light, oxygen, water), reduce the diffusion and evaporation of the core material to the environment, and make the core material release ...
