Nanometer anti-mite mothproof after-finishing reagent for woolen sweater as well as manufacturing process thereof

Abstract

The invention relates to a nanometer anti-mite mothproof after-finishing reagent for woolen sweater as well as a manufacturing process thereof. The manufacturing process comprises the following steps:taking a mixed type high-adhesion material as a wall material of a microcapsule, wherein the volume ratio of cyclodextrin to epoxy resin is (5-20):(5-10); dissolving an oily emulsifier and a mixed high-adhesion material into a toluene solution and stirring to form a solution A; taking a mixture of a broad-spectrum anti-mite agent and a natural insect-removing reagent as a core material of the microcapsule, and mixing and stirring a curing agent and a core material solution to form a solution B, wherein the volume ratio of the anti-mite agent to the insect-removing agent is 6:1 to 3:1, and thevolume ratio of the curing agent to the core material solution is 1:6; and performing processes of stirring, secondary curing, separation and filtration and the like to generate a microcapsule solution, namely the anti-mite mothproof after-finishing reagent for the woolen sweater. The anti-mite mothproof after-finishing reagent for the woolen sweater has the advantages of high viscosity, high dispersibility, washing resistance, no toxicity, environmental friendliness, low cost and simple manufacturing process.

Description

technical field [0001] The invention belongs to the intercrossing technical fields of chemical technology, textile technology and medical technology, and relates to the selection of reagent materials and the production of reagents, in particular to a nanometer anti-mite and anti-moth finishing reagent for woolen sweaters and a manufacturing process thereof. Background technique [0002] Microcapsule finishing technology is to wrap a layer of very thin and highly viscous colloidal film on the surface of the nano-scale core material to continuously release the core material during use, and finally make the textile maintain a certain finishing property for a long time. Using nanotechnology to make microcapsules to finish textile products has been reported, but the mixed use of anti-mite agents and moth-proof fragrances, and processed into fine nanoparticles that can be used for finishing woolen sweaters has not been reported. . At present, the nano-microcapsule technology obvi...

Using nanotechnology to make microcapsules to finish textile products has been reported, but the mixed use of anti-mite agents and moth-proof fragrances, and processed into fine nanoparticles that can be used for finishing woolen sweaters has not been reported.

At present, the nano-microcapsule technology obviously has the following defects in the application of textiles: one is that the reagent lacks high viscosity and cannot be well combined with the fiber; the other is that the reagent lacks dispersibility and cannot be evenly distributed to various regions of the fiber; Reagents lack persistence, and the washing resistance of textiles after treatment is very poor; fourth, most of the reagents contain formaldehyde and other substances, which are harmful to human body
