Problems solved by technology

However, phase change energy storage technology also has obvious disadvantages. The phase change material itself does not generate heat. It is still a passive "heat generation" and only stores the heat in the environment.
Passive heat production often means insufficient heat supply, insufficient heat retention capacity, and low efficiency

Embodiment 1

[0037] Padding liquid formula:

[0038] Phase change microcapsules 2-30%

[0039] Binder 2-30%

[0040] Water 40-96%

[0041] Wherein, phase change microcapsules (preparation method refers to article Journal of Applied Polymer Science, 2005,97:390) main component is capsule core is phase change alkane, and shell layer is urea-formaldehyde resin, or polymers such as polyurethane, and particle size can be varied. Controlled between 100 nanometers and 1000 microns.

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

[0043] The heat-generating fiber (cupro ammonia fiber or cross-linked acrylate fiber is selected here) is dipped and rolled twice, and then dried at 80°C. A heating fiber material with two-way temperature regulation function according to the present invention can be obtained.

Embodiment 2

[0045] 200g of phase-change microcapsule material dispersion (for the preparation method refer to the article Journal of Applied Polymer Science, 2005, 97: 390; Colloidal and Polymer Science, 280: 290), with 800g of distilled water, 1.5g of sodium polypropylene and 2g of di-succinate The alkyl ester sulfonate is mixed well until no solid material is evident. Use a commercially available pump spray bottle to spray the dispersion system obtained above evenly onto the heating fiber material. In this example, cupro ammonia fiber or cross-linked acrylate fiber can be used, and the spraying amount is the mass of the fiber material. 20%, and then dry the sprayed flakes at 100°C to obtain a heating fiber material with two-way temperature regulation function according to the present invention.

Embodiment 3

[0047] The phase change energy storage fiber, PVA / paraffin phase change energy storage fiber is selected here (refer to the Journal of Composite Materials for the preparation method, 2008, 25, 17-22), and the 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 two-way temperature regulation function of the present invention 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...
