Problems solved by technology

However, the active solution of silk protein is affected by the outside world, and the general treatment methods cannot perfectly modify silk
Generally speaking, the modification of silk is mainly to directly modify the silk, such as coating titanium dioxide or other components on the surface, but the coating on the surface of the modified silk prepared by this method is easy to lose, which not only causes residual pollution , and the performance of silk is not stable enough

Abstract

The invention relates to the technical field of skin-care products, and discloses a method for preparing a facial mask base material by using modified antibacterial silks as substrate. The method comprises the following steps (1) preparing a nano-silver solution; (2) preparing a nano-silver matching fluid; (3) preparing nano-silver containing mulberry leaves; (4) preparing modified mulberry leaves; (5) adding the nano-silver mulberry leaves to a mount cocooning frame for silkworms developing to the fourth day of the fifth instar, and reeling silkworm cocoons until the silkworms grow to the mounting stage to obtain nano-silver-containing mulberry silks; and (6) preparing silk fibers from the silks, cross spinning cotton staples and silk fibers into a facial mask. The facial mask prepared bythe method can be applied to various facial mask products, and has an important practical significance to development of the skin-care product industry in China.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a method for preparing a mask base material based on modified antibacterial silk. Background technique [0002] Mask is an important beauty and skin care product produced by contemporary people. Through the mask, people can complete a series of skin maintenance functions such as cleaning, moisturizing, moisturizing, sterilization, spot removal, whitening, and wrinkle removal. With the development of technology, more and more types of facial masks have been invented. At present, there are polyester, blended, kaolin blended, non-woven fabrics, cotton silk, silk, tencel, biological fibers and other products that are mainly used. Each of these masks has its advantages and disadvantages, and each has its own advantages and disadvantages. [0003] As the top grade of textile fibers, silk has incomparable advantages over other fibers. Silk has soft luster, smooth hand feeli...
