Abstract

The invention discloses a self-adhesive microcapsule for controllably perfuming textiles as well as preparation and application of the self-adhesive microcapsule, and belongs to the field of aromatic textile materials. According to the invention, the dopamine is adopted to modify the essence microcapsules, and the adhesion of the essence microcapsules on the fabric is controlled through Fe < 3 + >, so that the binding force of the microcapsules and the fabric is increased, and the preparation of the perfumed fabric is realized; and the microcapsules are removed through EDTA (Ethylene Diamine Tetraacetic Acid), so that the preparation of the aroma-removing fabric is realized. By means of the method, controllable perfuming of the fabric can be achieved, application of the fragrant microcapsules to textiles is facilitated, and development of functional fragrant textile products is promoted.

Description

technical field [0001] The invention relates to a self-adhesive microcapsule with controllable aromatization of textiles, preparation and application thereof, and belongs to the field of aromatic textile materials. Background technique [0002] With the development of society and the improvement of people's living standards, the functions of traditional textiles such as keeping warm, comfortable and protective can no longer fully meet the needs of modern people for a beautiful and healthy life. Aromatic substances can bring people a pleasant and comfortable feeling, and various flavored products have emerged as the times require. Flavor microcapsules can endow textiles with various effects such as aroma, antibacterial, and sleep aid, which can not only relieve the pressure in people's lives and maintain a happy mood, but also increase the added value of textiles and enhance market competitiveness. [0003] At present, most aromatic textiles are perfumed by means of essence ...
