Biocellulose slurry, and dry biocellulose material, method for manufacturing dry biocellulose material and skin care film using the same

Abstract

A bio-cellulose slurry is provided. The bio-cellulose slurry comprises the following components: bio-cellulose; a backbone fiber selected from the group consisting of rayon fibers, polyethylene terephthalate (PET) fibers, nylon fibers and combinations thereof; an adhesive fiber selected from polyethylene composite fibers; an adhesion promoter selected from the group consisting of polyamides, low density polyethylenes and combinations thereof; a humectant selected from polyols; and a dispersion medium. The bio-cellulose slurry is useful in manufacturing a dry bio-cellulose material with outstanding water absorption rate and wet strength.

Description

technical field [0001] The invention relates to a biological fiber slurry, which can be used to prepare dry biological fiber materials with excellent moisture absorption rate and wet strength. Therefore, the present invention also relates to a method for preparing a dry biofiber material, a dry biofiber material and a skin care film using the dry biofiber material. Background technique [0002] Biofibres are natural fibers grown using microbial fermentation, with a diameter of only about 20 nanometers, which is about 1,000 times thinner than human hair. As the fermentation progresses, the biological fiber can grow into a biological fiber film, which is the most delicate material known so far, the closest to the skin, and has excellent water retention and elasticity, so it is especially suitable for applications in the fields of beauty and biomedicine. For example, it can be used as a mask substrate to absorb skin care ingredients. [0003] However, the bio-fiber membrane h...

Problems solved by technology

[0003] However, the bio-fiber membrane has the disadvantage that it cannot restore water absorption after drying, so it must be kept in a wet state all the time, and cannot be made into dry rolls like the general non-woven mask substrate, which makes it difficult for the bio-fiber membrane to be continuously produced , and the inconvenience of storage and transportation

In addition, the biocellulose membrane will produce unusable waste after being cut. At present, these wastes are directly discarded and cannot be used. This not only causes waste, but also increases the inconvenience of waste disposal.
