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

preparation example Construction

[0026] The invention provides a method for preparing microcapsules for preparing temperature-regulating textiles, comprising the following steps:

[0027] (1) mixing the mixed solution comprising sodium alginate and calcium carbonate with paraffin and water-oil composite emulsifier, and carrying out an emulsification reaction to obtain an oil-in-water emulsion;

[0028] (2) mixing the oil-in-water emulsion obtained in the step (1) with sherwood oil and an acidic solvent, and performing a curing reaction to obtain primary microcapsules;

[0029] (3) The primary microcapsules obtained in the step (2) are condensed with chitosan acidic solution to obtain microcapsules for temperature-regulating textiles.

[0030] The invention mixes the mixed solution including sodium alginate and calcium carbonate with paraffin wax and water-oil compound emulsifier. In the present invention, the mass ratio of sodium alginate, calcium carbonate and water in the mixed solution is preferably (1-3)...

Embodiment 1

[0069] Preparation of microcapsules: in parts by mass, dissolve 1.0 part of sodium alginate and 0.5 part of calcium carbonate with 80 parts of water at 45°C, add 1.0 part of sliced ​​paraffin and 6 parts of water-oil compound emulsifier (water-oil compound emulsifier After being emulsified for 30min with a mass ratio of Tween-80 and Span-80) of 6:4, an oil-in-water emulsion was obtained; the oil-in-water emulsion was dispersed in 80 parts of petroleum ether and 0.25 part of acetic acid mixed solution, Stir at a speed of 2000rpm for 10min, then add 80 parts of 0.05mol / L calcium chloride aqueous solution, and also stir at a speed of 2000rpm for 10min to obtain primary microcapsules coated with paraffin wax sliced ​​by sodium alginate; place the prepared primary microcapsules in Mass concentration is 0.2% in the chitosan acetic acid solution, wherein the mass parts of chitosan is 2 parts, soak 0.5h, adopt xylene to wash 3 times, absolute ethanol wash 3 times and the mode of distil...

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...
