Problems solved by technology

The preparation method of the phase-change temperature-regulating cotton fiber is a physical method of adhesive bonding, so that the phase-change temperature-regulating main material is combined with the cotton fiber. During the long-term use of the cotton fiber, the failure of the adhesive will cause The phase change material falls off, thus making it lose its thermostat performance
[0009] At present, there is no technical disclosure of heat storage and heat preservation hydrogel finishing agent for textiles

Abstract

The invention discloses a heat storage and preservationhydrogel finishing agent for textile products and a preparation method of the heat storage and preservationhydrogel finishing agent. The preparation method comprise the following steps: mixing and dissolving 100 parts of N-isopropylacrylamide, 25-200 parts of chitosan and 1-3 parts of N,N-methylene-bisacrylamide at room temperature; adding 1-3 parts of potassium persulphate, then adding 1-3 parts of sodium hydrogen sulfite, and stirring uniformly for reaction at normal temperature for at least 24 hours to obtain a hydrogel; and drying the hydrogel at 60-80 DEG C, and grinding the dried hydrogel to prepare hydrogel powder. The heat storage and preservationhydrogel finishing agent is suitable for performing heat storage and preservation functional finishing on pure cotton fabrics, and is good in washing resistance.

Description

technical field [0001] The invention relates to a textile finishing technology, which is a thermal storage and thermal insulation hydrogel finishing agent for textiles, especially for pure cotton fabrics and a preparation method thereof. [0002] The phase change material to be prepared in the present invention is an organic phase change material, an organic polymer solid-solid phase change material, and a phase change hydrogel material. [0003] The invention synthesizes a phase change hydrogel through polymerization reaction and interpenetrating network technology, and the textiles finished by the hydrogel have the functions of heat storage, heat preservation and temperature regulation. technical background [0004] Phase change materials use their latent heat of phase change to realize energy storage and utilization, also known as latent heat energy storage materials, which are heat storage materials that can absorb or release energy during the phase change process. The ...
