Abstract

The invention discloses a preparation method of a pH value and temperature response, photocuring and one-way wet permeability multifunctional finishing agent for woven fabrics, belonging to the preparation field of textile chemicals. The preparation method comprises the steps: firstly, mixing deionized water, a biomass surfactant, polyhedral oligomeric silsesquioxane, nano-zinc oxide particles and silver nitrate, and then, adding ammonia water and reacting to obtain a functional reaction solution; and then, dropwise adding an N-isopropylacrylamide monomer for pre-emulsifying after heating the functional reaction solution; then, adding sodium azide and propylene glycol block polyether, heating till the end of the reaction and finally adjusting the pH value to 7-8. The preparation method disclosed by the invention is simple and low in cost; the prepared finishing agent is good in stability, high in activity and free of pollution; high-temperature curing is not needed, crosslinking and curing can be realized under illumination, and a baking process is omitted in the use process, so that the production effects of saving energy and reducing emission are achieved; and the multifunctional finishing agent is suitable for various textile fibers and woven fabrics and can be used for a long term.

Description

technical field [0001] The invention belongs to the field of preparation of textile chemicals, and in particular relates to a preparation method of a photocurable bismuth-based air-purifying finishing agent special for fiber fabrics. Background technique [0002] The moisture-conducting finishing of cotton fabrics generally needs to be baked at high temperature after moisture-conducting finishing. After moisture-conducting finishing, the wearability of the fabric will change significantly, such as air permeability and hand feeling, etc., will decline to varying degrees, and it contains Some harmful chemicals seriously affect consumers' wearing comfort. In one-way moisture-conducting finishing, different types of moisture-conducting finishing agents and different production processes have different effects on the wearability of fabrics. The amount of moisture-conducting finishing agents on the fabric and the selection of finishing anchor points have a direct impact. The finis...
