Problems solved by technology

[0003] At present, most of the aromatic functional finishing agents on the market are artificially synthesized essences. After long-term exposure, some sensitive consumers will not only not be able to obtain pleasant physical and mental gains, but will have some side effects and affect their health.
In addition, aromatic functional finishing agents generally have disadvantages such as poor washability and slow release of fragrance.

Abstract

The invention relates to a preparation method and application of a pure-natural fragrant microcapsule textile finishing agent, and belongs to the field of textile functional finishing. According to the preparation method, a nanometer material is used as a carrier to package or adsorb pure-natural fragrant essential oil, a capsule material having good binding capacity with pure-natural cellulose fibers is adopted to coat the carrier, so as to prepare the pure-natural fragrant microcapsule, and finally, the fragrant microcapsule is compounded with a binding agent to produce the pure-natural fragrant microcapsule textile finishing agent. The textile finishing agent is free from any toxic or side effects to a human body, and can effectively solve problems such as irritability due to use of synthetic essence. When the pure-natural fragrant microcapsule textile finishing agent is finished on the textile with a post-finishing method, the textile can release fragrance for a long time and keep strong washability, and the textile finishing agent does not influence hand-feeling and appearance style of the textile.

Description

technical field [0001] The invention belongs to the field of textile functional finishing, and in particular relates to a preparation method and application of a pure natural aromatic microcapsule fabric finishing agent. Background technique [0002] In ancient my country, flowers with aromatic smell were made into sachets that can release fragrance for a long time after removing their water. Putting them in the living room can not only play a role in pleasant mood, but also regulate human immunity. function. With the development of modern science and technology, the method of finishing fragrance on fabrics or fabrics in a certain way has been widely used, and is generally recognized by consumers, so various finishing agents with fragrance functions have also emerged at the historic moment. [0003] Most of the aromatic finishing agents currently on the market are artificially synthesized fragrances. After prolonged exposure, some sensitive consumers will not only be unable ...
