Abstract

The invention relates to a preparation method of a functional temperature adjusting texture, and particularly relates to a high potential heat temperature-adjusting texture prepared by in-situ generation of a photo-induced phase change microcapsule on the texture. The preparation method of the functional temperature adjusting texture includes steps of (1), preparation of phase change core material, acrylic acid wall material, and other raw materials; (2), preparation of oil phase and water phase components; (3), evenly emulsifying oil and water phases to obtain water-coated-oil emulsion; (4),placing the emulsion and the texture in a specific device, and making the emulsion glue beam attached on the texture generate the phase change microcapsule through the photo-induced polymerization. The method has the advantages that the adhering force of the capsule on the texture is strong and the texture is wash resistance through in-situ polymerization of the phase change microcapsule on the texture; the preparation of the temperature-adjusting texture is completed by one-step method, the technique is simple and cost is low; the temperature-adjusting texture is high in potential heat value,and very suitable for using as the temperature-adjusting fabric, flocculus or filler for the clothes and other textiles; the temperature adjusting effect is obvious.

Description

technical field [0001] The invention is a method for preparing a temperature-regulating fabric, specifically using ultraviolet light as a reaction condition to initiate the in-situ generation of phase-change microcapsules on the fabric. Background technique [0002] Phase change material (PCM) is a material that absorbs and releases a certain amount of latent heat during the phase change, converts energy with the outside world during the phase change, and keeps its own temperature constant through heat absorption and release, thereby being able to control the ambient temperature and energy. However, phase change materials are prone to leakage, phase separation, volume increase, certain corrosion and poor thermal performance when they are used. Microcapsule technology is a technology that uses film-forming materials to coat solid or liquid particles into particles with a core-shell structure, consisting of core materials and wall materials. Phase change microcapsules is the ...
