Abstract

The invention relates to a blumea oil microcapsule including a capsule core material and a capsule wall material with the mass ratio of 1:4 to 1:2, and the capsule wall material includes sodium alginate and gelatin with the mass ratio of 1:2 to 1:8. The invention also provides a preparation method of the microcapsule, and the preparation method using a spray drying method is simple and practicable, mild in condition, and easy in production; the microcapsule is prepared by using water as a solvent to avoid environmental pollution caused by the use of organic solvents. The invention also provides a multifunctional textile preparation method using 2D resin as an anti-wrinkle crosslinking agent, on the one hand through chemical bond 2D resin, a bridge grafting effect is played, and the composite microcapsule is grafted to a textile to prepare a multifunctional textile; on the other hand, capsule wall is cross linked and cured by use of free formaldehyde released by the 2D resin, the formaldehyde release amount of the finished textile is reduced, the sealing performance of the microcapsule wall is increased, the action time is prolonged, the microcapsule on the finished textile is insoluble in water, and the textile water-washing resistance is improved.

Description

technical field [0001] The present invention relates to the field of medicine microcapsule preparation technology and textile functional treatment, more specifically, relates to a kind of mugwort leaf oil composite microcapsule prepared by spray drying method and its specific preparation method, and multifunctional mugwort leaf oil composite microcapsule Preparation methods and applications of textiles. Background technique [0002] Microcapsule technology is a protective technology that encapsulates reactive, volatile, sensitive or odorous substances (core materials) through film-forming materials (wall materials) to form tiny particles. The process is called microencapsulation, and the tiny particles formed are called microcapsules. Microcapsule technology can achieve the purpose of controlling the release of core materials, protecting sensitive components, reducing or masking bad taste, isolating components, and turning liquid substances into pseudo-solids. With the con...
