Preparation method of textile fragrance treatment microcapsule

Abstract

The invention provides a preparation method of a textile fragrance treatment microcapsule. The preparation method comprises the steps of preparation of a crosslinking spice essential oil polymer, forming of the textile fragrance treatment microcapsule, ageing of the wall of the microcapsule and finished product drying. Liquid spice essential oil and an aliphatic isocyanate polymer are firstly mixed and stirred to generate the crosslinking spice essential oil polymer, and after instability caused by the original high permeability and high volatility of the spice essential oil is changed, through the action of an acrylamide solution and acrylamide propyl trimethyl ammonium chloride, the crosslinking spice essential oil polymer is packed to form the solid-state textile fragrance treatment microcapsule. The textile fragrance treatment microcapsule prepared through the method is small in particle size, good in packing performance and dispersity and strong in bonding force with textiles, specially cotton textiles, after the textile fragrance treatment microcapsule is used for later treatment of textiles, specially cotton textiles, the long-time gentle and comfortable fragrance can be kept, lingering fragrance can still be kept after multiple times of washing, and the textile fragrance treatment microcapsule is extremely popular with people.

Description

technical field [0001] The invention relates to a preparation method of microcapsules, in particular to a preparation method of textile fragrance treatment microcapsules, belonging to the technical field of textile treatment agent production. Background technique [0002] In recent years, scented textiles have become a new fashion, among which, cotton fabrics with long-lasting scents are becoming a promising variety of functional cotton fabrics, especially scented underwear, which are being favored by more and more women and even men. Highly sought after, expensive, high value-added products, and strong competitiveness. [0003] The aroma of scented textiles comes from the fragrances added during textile processing. [0004] Because most of the ingredients in the essence are highly volatile, sensitive to light, heat, and oxygen, and easily react with other substances to affect the purity of the aroma; in addition, the volatility of the essence will lead to the gradual disap...

AI Technical Summary

Problems solved by technology

[0016] In the preparation method of this essence microcapsule, comprise dissolving chitosan in the acetic acid solution, adding emulsifier and essence into above-mentioned chitosan acetate solution, high-speed emulsification dispersion obtains chitosan essence emulsion, sodium alginate and The mixed solution of sodium tripolyphosphate is added dropwise to the above-mentioned chitosan flavor emulsion, and the pH value of the system is adjusted to 5-7 with NaOH solution to obtain agglomerated flavor microcapsules. Adding a cross-linking agent to the above-mentioned coagulated flavor microcapsule system There are many steps in the chemical cross-linking treatment of flavor microcapsules, and the corresponding control requirements in each process are relatively strict. However, too many processes and control requirements will affect the quality of the product, which is not conducive to ensuring the quality of the product

[0017] In addition, in the above-mentioned prior art, it is mainly considered from the composition material and composition method of the microcapsule wall, and the high permeability and high volatility of the fragrance essential oil itself have not been fully considered, so that the microcapsules The wall is unstable due to the high permeability and high volatility of the fragrance essential oil itself, which affects the application of the product
