Problems solved by technology

On the one hand, if the content of phase change material is high, the temperature adjustment effect will be better, but it may make the feel of the thermal insulation material harder, and at the same time, the thickness of the material will also decrease, affecting its bulkiness

Embodiment 1

[0062] Choose 2D*51mm (Huvis 2080 produced by Huvis Company) polyester low-melting fiber (110°C) 2kg, other fibers use synthetic fibers, use 2D*51mm solid (110°C) 0.6kg, other fibers choose 2D*51mm solid viscose regenerated fiber (32S viscose fiber produced by Lenzing Company) 5.9kg, 7D*64mm hollow crimped synthetic fiber (YZK61A7D hollow fiber produced by Yizheng Company) 3.5kg, after mixing-coarse opening-fine opening After pine-feeding-carding processing, a single wire 10 is obtained, and three carding machines are used to work simultaneously, such as image 3 As shown, get three same single net 10, only for image 3 The single net 10 obtained by a carding machine in the middle is continuously sprayed with the emulsion containing phase-change microcapsules 20, and the phase-change microcapsule emulsion of the fatty acid ester core material produced by Aerospace Haiying (Zhenjiang) Special Materials Co., Ltd. is selected to control the amount of spraying Make the net conten...

Embodiment 2

[0068]Choose 1.5kg of low-melting fiber (ES fiber polyethylene / polypropylene fiber produced by Guangzhou Yiaisi Company) (130°C) with a specification of 2D*51mm, 2kg of natural fiber cotton for other fibers, and 2D*51mm solid silicon-containing fiber for synthetic fiber ( SN-8250S2D fiber produced by Yuanfang Company, 3kg, 7D*64mm hollow crimped fiber (YZK61A7D hollow fiber produced by Yizheng Company) 3.5kg, after mixing-coarse opening-fine opening-feeding-carding, the single Net 10, control parameters such as the output speed of single net 10, the speed of net laying and the time required for laying a layer of single net 10, and spray the emulsion containing phase change microcapsules 20 intermittently at regular intervals, so that cross-laying There is one layer of phase change microcapsules 20 on every two layers of single net 10 behind the net. The phase change material is the phase change microcapsule emulsion of MG26 paraffin core material of Beijing Guangyu Phase Chang...

Embodiment 3

[0070] Use polyester low-melting point fiber with a specification of 4D*51mm (4080 produced by Huvis Company)

[0071] It can be seen from the above table 1 that the sample of the embodiment of the present invention has no obvious difference in thickness compared with the comparative sample, and the process does not reduce the bulkiness, and can keep and approach the original bulkiness and softness when no phase change material is added as much as possible. Hand feeling: After 5 times of washing, the weight retention rate can reach 97-99%, and the phase change material is basically not lost.

[0072] Therefore, the method of the present invention provides a fluffy temperature-regulating thermal insulation material, which can use more phase change materials and disperse them in the volume of the thermal insulation material to obtain good temperature-regulating performance, while avoiding the use of dipping, traction, spunlace, and acupuncture And other processes that affect the...

Abstract

A method for producing a fluffy temperature regulating warmth retention material and the fluffy temperature regulating warmth retention material produced therefrom are disclosed. The method comprises: selecting a low melting point fiber and an additional fiber; carding to form a single web; spray coating a phase change material along at least part of the length of a surface of the single web; lapping layer by layer of the single web; and performing a heat setting reinforcement to form the warmth retention material. According to the present invention, a fluffy temperature regulating warmth retention material comprising an appropriate ratio of a phase change material may be obtained and the material exhibits a satisfactory temperature regulating effect, and meanwhile, it can maintain, to the full extent, or is close to, the original filling power and soft hand feeling where no phase change material is incorporated. In addition, the phase change material can be retained very well within the fluffy temperature regulating warmth retention material and thus has a wash resistance property.

Description

technical field [0001] The invention relates to the field of temperature-regulating and heat-retaining materials, in particular to a method for manufacturing a fluffy temperature-regulating and heat-retaining material and the fluffy temperature-regulating and heat-retaining material manufactured therefrom. Background technique [0002] Common thermal insulation materials in the market mainly include natural flakes (including cotton, wool, down, etc.) and synthetic flakes (mainly synthetic fiber flakes). Prevent or insulate heat loss. Therefore, thermal insulation materials need to have or form a bulky structure. [0003] A thermal insulation material has a phase change material added to the thermal insulation material to achieve temperature regulation on the object to be kept warm. The phase change material can be distributed on the upper and lower surfaces of the thermal insulation material, or gradually enter the thermal insulation material. On the one hand, if the conte...
