Microcapsule for preparing temperature-adjusting textile product, preparation method and application thereof, as well as temperature-adjusting textile product

Abstract

The invention provides a preparation method of a microcapsule for preparing a temperature-adjusting textile product. The preparation method comprises the following steps: mixing mixed liquid of sodium alginate and calcium carbonate, paraffin and a water-oil composite emulsifying agent, and performing emulsifying reaction to obtain oil-in-water emulsion; mixing the obtained oil-in-water emulsion, petroleum ether and an acidic solvent, and performing curing reaction to obtain a primary microcapsule; performing condensation reaction on the obtained primary microcapsule and a chitosan acidic solution to obtain the microcapsule for coating the surface of the textile product. Results of embodiments show that after the temperature-adjusting textile product, of which the surface is coated with the microcapsule prepared by the method, is washed with water for 1 to 5 times, the mass loss rate is lower than 5 percent, so that the firmness of a phase-change material and a base fabric is high.

Description

technical field [0001] The invention belongs to the technical field of textile fabric production, and in particular relates to a microcapsule for preparing temperature-regulating textiles, a preparation method and application thereof, and temperature-regulating textiles. Background technique [0002] With the improvement of people's living standards, people's requirements for the function of textile fabrics are getting higher and higher. Temperature-regulating textiles are a new type of intelligent textiles that can release energy when the temperature is low, absorb heat when the temperature rises, and lower the temperature; temperature-regulating textiles have the function of two-way temperature regulation, and can automatically absorb, store, distribute and release energy. Improves wearer comfort. [0003] The preparation principle of temperature-regulating textiles is to add phase-change temperature-regulating materials to the surface of textiles, and directly spin to pr...

Problems solved by technology

Although the existing technology can prepare temperature-regulating textiles, due to the limitations of the process and formula, the phase-change materials and textiles will have poor firmness during the subsequent use of the prepared temperature-regulating textiles, and the phase change materials will change with time. The increase in the number of washings detaches from the surface of the textile and loses its temperature-regulating properties

For example, Chinese patent CN200810061268.8 discloses a preparation method of an intelligent temperature-regulating functional yarn. Or the sizing process is arranged on the yarn, and then the temperature-adjusting textile is produced through the subsequent weaving technology; however, the invention uses the finished microcapsule emulsion to finish the yarn, and does not consider the combination ability of the microcapsule and the yarn, resulting in temperature-regulating textiles. The microcapsules fall off during the subsequent use of the textile, losing its thermoregulation properties

For another example, Chinese patent CN201410407505.X discloses an intelligent temperature-regulating textile and its preparation method, which uses a coating adhesive to wrap and mix phase-change microcapsules, and then coats them on the surface of the textile fabric. The prepared temperature-adjusted textile still has the problem of poor fastness between the coating and the substrate
