Description

Piezoelectric micro-power generation heating health-care textile and preparation method thereof
Technical Field
The invention relates to the technical field of fabric fabrics, in particular to a piezoelectric micro-generation heating health-care textile and a preparation method thereof.
Background
With the development of functional textiles, textiles with heating health care functions are well developed. People tend to choose the heating fiber to make clothes. For example, the existing functional fiber can finish the warm-keeping work by absorbing the infrared rays emitted by the human body and reducing the loss rate of water vapor in the skin of the human body. However, the heat supply of the warm-keeping mode is limited, and the heating effect is not obvious through a large amount of verification.
At present, a chemical reaction fabric which generates heat outwards by oxidation reaction of materials such as iron powder in the air is available. However, the fabric made of the fiber is a chemical reaction fabric which utilizes iron powder materials to generate heat, and when the iron powder in the fabric is completely oxidized by oxygen in the air, the heat is not released outwards any more, and the durability is limited.
With the progress of the technology, the graphene has a good low-temperature far infrared function and very strong heat exchange capacity in the heating medium popularized and applied in recent years. Has huge application markets in the aspects of household low-temperature heating, medical health care heating and the like. The heating principle of the graphene is that under the driving action of an electric field, the graphene generates microscopic Brownian motion, violent friction and impact heating occur among carbon molecules, and generated heat energy is transmitted by far infrared rays. Can realize low energy consumption and low voltage heating. The method provides an excellent technical idea for the development of heating health-care functional textiles.
Chinese patent No. CN108179627A discloses a graphene clothing material and a manufacturing method thereof, comprising the steps of: preparing raw materials, comprising: 25-45% of graphene nano raw material, 35-55% of cotton fabric carrier, 6-10% of sodium styrene sulfonate powder, 10-18% of deacetylation degree, 8-13% of chitosan and 15-30% of negative ions, wherein the sum of the contents of the components is 100% by weight; pretreating raw materials: and the raw material compositions in the step (1) are mixed and stirred for 1 to 3 hours according to the proportion; and mixing the above ingredients, placing the mixture into a pulping machine, sucking pulp through a pulp trough, drying for 40-80 minutes through a drying box, and collecting the 600-mesh 800-mesh graphene clothing material raw powder. The graphene is used in the clothing material, and the clothing prepared from the graphene material has the advantages of good air permeability, strong antibiosis, good heat preservation, static electricity prevention, and functions of releasing far infrared rays, absorbing moisture, eliminating dampness and the like.
Chinese patent No. CN109232927A discloses a preparation method of antistatic antibacterial far infrared thermal textile containing graphene, which comprises the steps of coating a polyurethane composite solution on a BOPP film, curing to form a thin film, compounding the thin film with the textile, peeling off the BOPP film, reducing the obtained compounded textile by hydrazine hydrate with the mass concentration of 2-7% at 70-90 ℃ for 3-5 hours, washing and drying to obtain the antistatic antibacterial far infrared thermal textile containing graphene; the compounding process of the film and the textile comprises the steps of coating an adhesive on the surface of the formed film, and bonding the film and the textile through the adhesive, wherein the bonding temperature is 60-100 ℃, the pressure is 0.3-0.5MPa, and the time is 0.5-2 hours. The preparation method disclosed by the invention can improve the dispersibility of the graphene and the bonding fastness with textiles, is washable, and can keep good antistatic, antibacterial and far infrared heat-insulating effects.
Therefore, the graphene is used for textile materials in the prior art, and the function of keeping warm is achieved by releasing far infrared rays. However, the thermal insulation effect of the fabric is limited by simply adding graphene into the raw materials of the textile material. For heating healthcare textiles, this is also typically accomplished by external electrical heating. In addition, in the method of adding graphene into a textile material in the prior art, the graphene is usually dispersed in nylon and then formed into filaments as a non-woven material; graphene dispersion and adhesives are coated on non-woven fabrics, so that the graphene is low in firmness and limited in dosage.
