Problems solved by technology

[0004] In recent years, with the increasing number of extreme weather, people have put forward higher requirements for the thermal performance of textiles. Among the common fiber materials, animal fibers, such as cashmere and duck down, have the best thermal performance, but they have been used many times. Animal protection organizations broke the news of cruelty to animals to obtain the above materials. Airgel has been used in some fabrics due to its low thermal conductivity. However, there are no thermal fabrics that are both warm and comfortable as well as lightweight and quick-drying on the market.

Abstract

The invention provides graphene aerogel thermal fabric. The graphene aerogel thermal fabric comprises an upper surface layer, a spacing layer and a lower surface layer, wherein the spacing layer is connected with the upper surface layer and the lower surface layer; the spacing layer is woven by aerogel yarns; the upper surface layer and the lower surface layer are woven together through the aerogel yarns; the upper surface layer is of a uniform breathable structure; the upper surface layer, the spacing layer and the lower surface layer are integrally woven and formed; the upper surface layer,the spacing layer and the lower surface layer are subjected to three-line yarn feeding through a 3D warp knitting machine; and the upper surface layer, the spacing layer and the lower surface layer are woven simultaneously. According to the graphene aerogel thermal fabric provided by the invention, fabric of the upper surface layer is woven by adopting cellulose fiber yarns, the middle spacing layer is woven by adopting aerogel yarns, and the lower surface layer is woven by adopting graphene pure-spun or blended yarns; the air permeability, moisture permeability, softness and comfort of the fabric are improved, and the fabric has excellent warmth retention property and the performances of light weight, quick drying and peculiar smell resistance; and fabric of the lower surface layer has far-infrared, antibacterial and antistatic health-care functions, a heat effect is generated, and blood circulation is promoted.

Description

technical field [0001] The invention relates to the field of weaving technology, in particular to a graphene airgel thermal fabric. Background technique [0002] With the continuous development of science and technology and the improvement of people's living standards, ecological and healthy products have become a new height that people pursue. People's clothing and articles are not only satisfied with practicality and durability, but also begin to pursue comfort and environmental protection. In the field of weaving, fibers with different functions are mixed, and the functions of various fibers are combined to broaden the range of functions and health care effects. [0003] Graphene is a two-dimensional carbon nanostructure material that is an allotrope with fullerenes and carbon nanotubes.
