A kind of intelligent thermoregulation composite cotton and preparation method thereof

Abstract

The invention discloses intelligent thermoregulation composite cotton and a preparation method thereof. The cotton is characterized by being prepared by compounding ordinary cotton and organic phase-change substances. The preparation method comprises the following steps: firstly, respectively weighing a certain mass of cotton and an organic phase-change substance (such as paraffin or stearic acid) according to a certain ratio, subsequently respectively dissolving the phase-change substances into a proper amount of a solvent, putting the solution into water bath with certain temperature, continuously stirring for a certain period of time so as to sufficiently disperse and dissolve a phase-change material, further respectively adding the cotton which is weighed in advance into the solution with the organic phase-change substances, soaking for a certain period of time to enable the cotton to sufficiently adsorb the phase-change substances, subsequently evaporating to dry the solvent at certain temperature so as to obtain an organic phase-change substance / cotton composite material, that is, the intelligent thermoregulation composite cotton. The preparation method is simple and convenient to operate, low in cost and environment-friendly, the prepared composite cotton can intelligently regulate the self temperature according to temperature change of the application environment so as to maintain the temperature within a phase-change temperature range, and the product has wide application values.

Description

technical field [0001] The invention belongs to the field of phase-change heat storage composite materials, and in particular relates to the design and preparation of composite cotton with intelligent temperature-regulating function. Background technique [0002] With the development of the economy and the continuous improvement of the people's requirements for the quality of life, the research and development of an intelligent temperature-regulating cotton with excellent heat preservation and cold protection and cooling and heat removal functions has become a technical problem that needs to be solved urgently. Traditional textiles only have a one-way temperature regulation function. At present, some thermal insulation fibers or comfortable moisture-wicking fibers and cooling fibers have been developed, but these materials are powerless against supercooled and overheated environments, and cannot achieve dual thermal insulation-cooling functions.

Problems solved by technology

However, the current application of phase change materials on textiles is usually to encapsulate the phase change materials in microcapsules to coat the fabric, or to mix the microcapsules into the spinning solution for spinning. 1.0-10.0μm phase change material microcapsules, and then coating or spinning, the technical route is complicated, difficult to control, and high cost; and the load of phase change material in the fabric is small and easy to fall off, resulting in poor temperature regulation performance obvious
