Description
Technical Field
The utility model relates to the field of clothes, in particular to a graphene aerogel jacket.
Background
In the prior art, the application of graphene to textiles is mostly realized in a mode of performing after-finishing on fabrics, the mode is relatively widely applied to the research, development and preparation of functional textiles in recent years, and the functional finishing of graphene mainly has 4 application types. One is a graphene antibacterial fabric. Graphene and graphene oxide have excellent antibacterial performance, the cytotoxicity is 0 grade, the graphene and graphene oxide can be in direct contact with human skin, and the antibacterial fabric with good washing resistance can be prepared by finishing the graphene and graphene oxide on the fabric in adsorption, crosslinking and other modes. And the other is graphene conductive fabric. Graphene is the material with the smallest resistivity at present, and the excellent antistatic or conductive fabric can be prepared by processing the graphene on the fabric in a coating mode. Graphene oxide is used as a dye, the graphene oxide dyed fabric is prepared through the traditional dyeing process, and the graphene oxide dyed fabric with excellent conductivity can be obtained after reduction. And thirdly, the graphene ultraviolet-proof fabric. The graphene nanosheets are used as ultraviolet absorption materials, and the fabric is subjected to coating finishing by adopting padding and baking methods, so that the graphene coated fabric with high ultraviolet protection performance is prepared. And fourthly, the graphene flame-retardant fabric is compounded with the aminated modified graphene oxide and the flame retardant to prepare the coating, so that the flame retardant property of the composite coating can be improved, the use amount of the flame-retardant coating in the fabric is reduced, and the cost is reduced.
In addition, a subject group of professor Zhejiang university in 2013 manufactures a super-light substance, namely graphene aerogel. The material is called as the lightest material in the world, has the density of 1/6 of air, has good heat preservation performance and adsorption performance because the internal pores are abundant and are filled with air, can be used for treating offshore crude oil leakage, and can also be an ideal catalyst carrier and high-efficiency composite material. The graphene aerogel is light in weight and low in heat conductivity, so that the traditional cotton clothes filling material can be replaced by the graphene aerogel, the heat insulation performance of clothes is improved, human body movement is facilitated, and the problem of low wearability caused by the fact that the graphene aerogel is fragile is still to be solved.
The factors influencing the warm-keeping performance of the clothes mainly comprise the following aspects: thermal insulation material, clothing covering area, clothing thickness, clothing opening position, clothing composition, wearing mode and the like. Current thermal garments are constructed of multiple layers of material, primarily to improve cold resistance by changing these factors. The warm-keeping material is the most main factor influencing the warm-keeping performance of the clothes, the outer layer material of the clothes generally has a windproof function, cotton or chemical fiber materials are adopted, the filling layer mainly comprises cotton wool, down feather, chemical fiber wadding and the like, and the warm-keeping effect is achieved mainly by increasing the thickness of the clothes. Secondly, reasonable wearing layers are formed by reasonably matching the clothes, the heat-insulating capability of the clothes is effectively adjusted, the clothes generally comprise cold-proof coats, sweaters or fleece coats, shirts or T-shirts and the like, thick clothes are not beneficial to human body movement, the moisture absorption and heat-insulating performance of the clothes is reduced after movement, and the appearance is influenced by the phenomena of cotton leakage and the like caused by repeated washing. Space navigation series clothes are promoted by the aid of the pixel surge technology, and the aerogel composite thermal insulation material 'blue-odd heat' is used, so that the clothes have good cold-proof and thermal insulation performance and are lighter and thinner than traditional down jackets.
Aerogel Technologies, Inc. in the United states developed an Aerogel thermal array useful in the footwear field based on the Aerogel available from Aspen Aerogels, which is a porous material made by impregnating a silicon Aerogel into a non-woven flexible substrate, with thermal properties 2-8 times that of conventional thermal properties.
Conventional garments are usually worn with increased garment thickness, wadding or multiple layers to achieve a warming effect, which brings with it a series of disadvantages: heavy clothing can severely limit the limb movement of a wearer, reduce the normal mobility of the wearer and influence the appearance of the wearer; the clothes are compressed in the movement process, the thickness of an air layer is reduced, and the heat insulation effect is reduced; after the clothes are sweated during sports, the fibers absorb moisture, so that the warm-keeping effect of the clothes can be greatly reduced; the conventional cotton clothes are easy to run cotton after being washed for many times, the warm-keeping effect is reduced, and the appearance is influenced. The existing aerogel has the problems of powder falling and the like, the agglomeration phenomenon of nano particles can be generated after washing, the heat retention is reduced, and the aerogel felt is relatively stiff.
Therefore, the above means can not achieve the ideal wearing effect, and the design of a garment with good warm-keeping effect, comfortable wearing, light weight and no influence on limb movement is urgently needed. In view of the above-mentioned defects, the design team actively makes research and innovation to create a jacket that overcomes the above-mentioned defects, so that the jacket has industrial utilization value.
