Problems solved by technology

[0010] Both of the above two patents use the coating method to bond the antibacterial agent or antibacterial microcapsules to the fabric through the adhesive, and the fabric obtains antibacterial properties through the above method, but the antibacterial agent or antibacterial microcapsules are directly bonded by the adhesive On fabrics, antibacterial agents or antibacterial microcapsules have poor affinity with fabric fibers, and their active ingredients cannot be retained for a long time; and post-treatment of fabrics by coating methods will reduce the air permeability of fabrics and reduce the comfort of textiles

Abstract

The invention discloses an isatis root oil microcapsule and an isatis root oil microcapsule functional fabric finishing agent. The isatis root oil microcapsule of the invention has a particle size of 5-10 microns, and a mass ratio of a core material and a wall material of 1:0.5-1.75; the isatis root oil microcapsule functional fabric finishing agent comprises 40-65% of isatis root oil microcapsule emulsion, 5-15% of crease resistant cross-linking agents, 1.5-5% of catalysts, 0.2-2% of penetrating agents, 5-8% of softeners, and 10-35.75% of water. The isatis root oil microcapsule of the invention can cover adverse smell of isatis root oil, slowly release isatis root oil, maintain the stability of isatis root oil, and prolong its efficacy. The isatis root oil microcapsule functional fabric finishing agent of the invention provides finished fabrics with a plurality of functional effects such as durable and antibacterial effect, antiviral effect, and crease resistance, and provides fabrics with good softness and permeability.

Description

technical field [0001] The invention belongs to the fields of pharmaceutical preparations and fabric treatment, and in particular relates to isatidis oil microcapsules and a preparation method thereof, and a functional fabric finishing agent prepared from isatidis oil microcapsules, a preparation method and application thereof. Background technique [0002] Radix Isatidis is the dried root of Isatis indigo, a plant of the genus Isatis in the cruciferous family. Studies have shown that Banlangen can be used to treat febrile diseases, fever, spots, sore throat, erysipelas, wind-heat cold, etc. It also has antibacterial, anti-cancer, anti-endotoxin, blood circulation, blood stasis and immune regulation effects. Therefore, Radix isatidis, as a traditional Chinese herbal medicine in my country, has received extensive attention in the research and development of its pharmaceutical preparations, especially after the prevention and control effects of Radix isatidis on SARS and H5N1 ...
