Embodiment 1

[0037] 200g phase-change microcapsule material dispersion (the dispersion is an emulsion, that is, the phase-change microcapsules are dispersed in water or other solvents, the main component is that the capsule core is phase-change alkane, and the shell layer is urea-formaldehyde resin, or other materials such as polyurethane) Polymer, the particle size is controlled between 100 nanometers and 1000 microns, the preparation method can refer to the article Journal of Applied Polymer Science, 2005, 97: 390; Colloidal and Polymer Science, 280: 290), and 800g distilled water, 1.5g polypropylene Sodium and 2 g of dialkyl sulfosuccinate were mixed well until no solid matter was evident. Use a commercially available pump spray bottle to evenly spray the dispersion system obtained above onto the flakes made by traditional techniques. In this example, commercially available cashmere flakes and commercially available flakes are sprayed. , the amount of spraying is 20% of the mass of the ...

Embodiment 2

[0040] The mass ratio of each fiber raw material is as follows:

[0041] Down (duck or goose down,) 30%, polyester fiber 62%, bonding fiber (polypropylene fiber) 8%.

[0042] The phase change material emulsion and adhesive (formaldehyde-free environmental protection adhesive, choose Yihui Chemical PUD water-based polyurethane composite adhesive, or Dongfang Rohm and Haas ST954 water-based adhesive, etc.) are uniformly mixed according to the mass ratio of 9:1. mix.

[0043] Wherein, phase change material emulsion formulation (mass parts) is:

[0044] 570 parts phase change paraffin

[0045] 200 parts of ammonia solution of sz25010 (polyscope) (solid content 15%)

[0046] 230 parts deionized water

[0047] The raw material fibers are mixed, the mixed fibers are carded, the web is laid, and after the web is formed, the web is drawn. The two sides of the fiber web are sprayed with the mixed solution of the phase change material and the adhesive, and the spraying amount is 15%...

Embodiment 3

[0051] The mass ratio of each fiber raw material is as follows:

[0052] Down (duck or goose down,) 30%, polyester fiber 62%, bonding fiber (polypropylene fiber) 8%.

[0053] The raw material fibers are mixed, the mixed fibers are carded, the web is laid, and after the web is formed, the web is drawn. Spray the adhesive on both sides of the fiber web (environmentally friendly adhesive that does not contain formaldehyde, choose Yihui Chemical PUD water-based polyurethane composite adhesive, or Dongfang Rohm and Haas ST954 water-based adhesive, etc.), the spraying amount is the fiber web quality 10% of.

[0054] The phase-change material powder (this powder is the microcapsule powder with lauryl alcohol as the capsule core and the urea-formaldehyde resin as the shell material) is obtained by the method described in the following documents, and then the obtained powder is filtered, and the particle size of the powder is In the range of 2 to 50 microns, the preparation method re...

Abstract

The invention relates to a wadding flake with a function of intellectualized thermoregulation and a preparation method thereof. The wadding flake is a base material which is made from a phase change material and an animal fiber, a plant fiber, a man-made fiber and/or a synthetic fiber by means of a fiber textile method or a fiber weaving method and formed by compounding through a certain method. The compounding method can be achieved by one of the technologies of padding, soaking and water sucking, atomizing and spraying and coating or by any combination of the above technologies. The wadding flake can react to an environmental temperature intelligently and absorb, store and release heat correspondingly with rising or falling of the environmental temperature so as to achieve a bi-directional adjustment of a micro-environmental temperature.

Description

technical field [0001] The invention relates to a floc with intelligent temperature regulation function and a preparation method thereof. Background technique [0002] Traditional wadding is made of natural cotton, silk fiber or artificial synthetic fiber. The principle is to use the gap or interlayer formed by fiber weaving or weaving to isolate the internal and external air flow and achieve the purpose of heat preservation. [0003] Maintaining a constant body temperature and feeling comfortable is the first requirement for clothing. With the continuous improvement of living standards, people have higher and higher requirements for the use and wearing of quilts and clothes. However, the flakes used for quilts and clothes can no longer meet these requirements. Ideal quilts and clothes should be both light and warm, and it is best to be able to use them in spring, summer, autumn and winter. Traditional flakes are often powerless to meet these requirements. [0004] Facing...
