Along with the continuous expansion of the application scenes of the down jackets, the down jackets applicable to multiple scenes are increasingly required in the market; because the down jackets are internally filled with down, cleaning and airing are time-consuming and labor-consuming, the down jackets are required to be warm-keeping and have good antibacterial property and antistatic property. Therefore, the fabric of the down jacket has higher requirements.
In recent years, the antibacterial performance of graphene is slowly researched and developed, and the antibacterial application of graphene can not only cut the cell membrane of bacteria, but also destroy the cell membrane by directly pumping phospholipid molecules on the cell membrane in a large scale so as to kill bacteria. At present, the graphene antibacterial property can be applied to textiles such as underwear, socks and bedding, the strong physical antibacterial property of the graphene antibacterial fabric is also continuously accepted by the market, and compared with other antibacterial fiber textile applications in the market, the graphene antibacterial fabric has strong advantages in making down jackets.
The printing paste is an organic substance with general colloid property, can be dissolved or expanded in water to form thick and plastic paste, can be used as a transfer agent for attaching dyes and other chemicals to fabrics, and can be removed after printing fixation is finished. The sizing agent does not participate in the chemical reaction in printing and only plays a medium role; the graphene is added into the printing paste, so that the printing paste has excellent antibacterial property, ultraviolet resistance and other performances, bacteria on clothing can be greatly reduced, ultraviolet resistance of the fabric is improved, and human health is protected. CN108797152a discloses a graphene printing slurry and a preparation method thereof, wherein the slurry comprises the following components in percentage by mass: 0.5-12% of graphene microcapsule, 0.1-5% of sodium alginate, 1-5% of thickener, 0.1-5% of dye, 0.5-3% of calcium carbonate, 0.01-0.05% of hydroxymethyl cellulose sodium, 0.1-2% of urea and the balance of water; according to the invention, the graphene microcapsules are added into the printing slurry, and the printing slurry is optimally proportioned with other components, so that the printing fabric with exquisite patterns can be produced and prepared through the traditional printing process, the obtained printing fabric has good permeability, is firm in coloring, and has the color fastness in washing reaching more than 4 levels, and meanwhile, the printing slurry has excellent antibacterial property, ultraviolet resistance and other performances, so that bacteria on clothing can be greatly reduced, the ultraviolet resistance of the fabric is improved, and the human health is protected. Although the graphene fabric prepared from the printing paste containing the graphene has good antistatic effect and antibacterial effect, the thermal insulation effect is relatively common, the temperature is generally raised to be only 2-3 ℃, and the requirement of consumers on thermal insulation cannot be met.
Therefore, in order to solve the above technical problems, there is a need to develop a composite printing paste having excellent antibacterial property, antistatic property and thermal insulation property.
