Chitosan fiber facial mask cloth and preparation method thereof

Abstract

The invention provides chitosan fiber facial mask cloth and a preparation method thereof. The preparation method is characterized by comprising the following steps: firstly, preparing the chitosan fiber facial mask cloth, wherein the content of chitosan fibers in the chitosan fiber facial mask cloth is 5 to 100 percent; secondly, dissolving succinic anhydride into an organic solvent to form bath lotion, taking and putting a certain amount of the chitosan fiber facial mask cloth into the bath lotion and controlling the temperature and reaction time of the bath lotion; thirdly, after the reaction is ended, carrying out centrifugal dewatering on the chitosan fiber facial mask cloth; fourthly, carrying out immersion cleaning on the chitosan fiber facial mask cloth by using the organic solventand washing off residual liquid after the reaction; fifthly, drying the chitosan fiber facial mask cloth after centrifugal dewatering is carried out, thereby obtaining modified chitosan fiber facial mask cloth. The facial mask cloth has the advantages of high liquid bearing capacity, long moisturizing time, good laminating property, transparence after liquid absorption, good antibacterial property, good flexibility, smooth and uniform cloth surface, high rate of finished products and low production cost.

Description

technical field [0001] The invention belongs to the technical field of skin care products, in particular to a preparation method of chitosan fiber mask cloth. Background technique [0002] With the improvement of people's living standards, beauty and skin care have become the most basic needs of life, and facial masks have now become an indispensable skin care product for women, and various facial masks are flooding the market. As a skin care product, facial mask mainly embodies the functions of moisturizing, whitening, repairing and wrinkle removal. The structure of facial mask is mainly composed of mask cloth, essence and outer packaging. Some masks are also equipped with auxiliary mask paper. Most of the current mask cloths are made of chemical fibers (such as: viscose fiber, tencel fiber and cupro ammonia fiber, etc.), spunlace, hot air, melt blown and other non-woven fabrics after film cutting. The different components of the essence make the mask exhibit various funct...

Problems solved by technology

[0003] In addition, most of the fibers used to make mask cloth are white chemical fibers, which are only used as the basic material of the mask cloth. After absorbing liquid, there is no change. The mask containing essence will appear whiter when applied to the skin, making the face more beautiful. It is ugly, and the film cloth has a certain thickness. After a long time of sticking on the face, as the essence volatilizes, it is easy to wrinkle, uneven, and the application effect is not good. In addition, there are reports that the total number of bacteria in many masks exceeds the standard, and the face There are also a lot of bacteria on the skin, so in addition to the antibacterial ingredients in the essence, a mask cloth with antibacterial effect is also necessary

[0004] The mask cloth currently used is generally made of tencel, viscose or polyester fibers through spunlace non-woven fabrics, and the weight is generally 20g / m 2 Above, some mix 10% to 50% chitosan fibers with other fibers to produce spunlace non-woven fabrics, which can inhibit bacteria, absorb heavy metals, and repair damaged skin. When used in combination, there are still problems such as small amount of liquid carrier, short moisturizing time, opacity, and poor application

Using high-absorbent chitosan fibers can basically solve the above problems, but the liquid-absorbent chitosan fibers will swell when exposed to water during the spunlace production of mask cloth, and will be destroyed after drying. The uniformity of the mask cloth surface makes the mask cloth hard and unusable
