Example Embodiment

[0036] Example 1:

[0037] Padding liquid formula:

[0038] Phase change microcapsule 2-30%

[0039] Adhesive 2-30%

[0040] Water 40-96%

[0041] Among them, phase change microcapsules (refer to the article Journal of Applied Polymer Science, 2005, 97: 390 for preparation methods) are mainly composed of phase change alkanes in the core and urea-formaldehyde resin in the shell, or polymers such as polyurethane. The particle size can be Control between 100 nanometers and 1000 microns.

[0042] The adhesive is room temperature adhesive NJ101 (provided by Jiangshan Hongxin Printing Material Co., Ltd.).

[0043] The heating fiber (Copper ammonia fiber or cross-linked acrylate fiber is used here) is double-dipped and double-rolled, and then dried at 80°C. The heating fiber material with bidirectional temperature adjustment function described in the present invention can be obtained.

Example Embodiment

[0044] Example 2

[0045] 200g phase change microcapsule material dispersion (refer to the article Journal of Applied Polymer Science, 2005, 97: 390; Colloidal and Polymer Science, 280: 290), and 800g distilled water, 1.5g sodium polypropylene and 2g succinate The alkyl ester sulfonate is mixed uniformly until there is no obvious solid matter. Use a commercially available pump spray bottle to spray the dispersion system obtained above onto the heating fiber material uniformly. In this example, cupra or cross-linked acrylate fiber can be used. The spray amount is the quality of the fiber material. Then, the sprayed flakes are dried at 100°C to obtain the heating fiber material with bidirectional temperature adjustment function of the present invention.

Example Embodiment

[0046] Example 3

[0047] The phase change energy storage fiber is selected here PVA / paraffin phase change energy storage fiber (the preparation method refers to Journal of Composites, 2008, 25, 17-22), and cross-linked acrylate fiber and acrylic fiber (the ratio of the three is Phase change energy storage fiber / heating fiber / acrylic fiber, 80:4:16) for blending. After weaving, the heating fiber material with bidirectional temperature adjustment function can be obtained.

Abstract

The invention aims to provide a novel heating fiber material with a bidirectional temperature regulating function and a preparation method thereof. The fiber material comprises phase-change materials and heating fibers. The preparation method is characterized in that the phase-change materials and the heating fibers are combined to form the heating fiber material with the bidirectional temperature regulating function. Phase-change energy storage technology and heating fiber technology are organically combined, so that active heat production and bidirectional temperature regulation are simultaneously realized.

Description

technical field [0001] The invention relates to a novel heating fiber material with two-way temperature regulation function and a preparation method thereof. Background technique [0002] The traditional method of keeping warm is to control the heat loss caused by heat conduction, convection, and radiation, such as using thick fabrics or cotton wool to keep warm, which can be said to passively keep heat. However, modern society has higher and higher requirements for clothing comfort, functionality, and aesthetics. Traditional thermal clothing is fluffy and bulky, which is inconvenient for activities and lacks aesthetic feeling. [0003] In order to meet these needs, people have successfully developed active heat-generating thermal insulation materials-heating fibers, including hygroscopic heating fibers, electric heating fibers, light energy heating fibers, chemical heating fibers and so on. Among them, the technology for producing moisture-absorbing and heating fibers is r...
