Facial mask base cloth based on nano cellulose fibers and preparation method of facial mask base cloth

The invention relates to the field of mask base cloth, in particular to mask base cloth based on nano-crystalline cellulose fibers and a preparation method of the mask base cloth. Nano-crystalline cellulose is subjected to carboxylation treatment, and chitosan fibers are prepared from the carboxylated nano-crystalline cellulose and chitosan through wet spinning; chitosan fibers and polylactic acid fibers are mixed and woven to form chitosan composite cloth; the preparation method comprises the following steps: modifying haw ginseng, starfish shell collagen and bletilla striata polysaccharide, introducing the modified haw ginseng, starfish shell collagen and bletilla striata polysaccharide into mask base cloth, modifying the starfish shell collagen with genipin, preparing nano-particles entrapped with haw ginseng by using sodium alginate as a material through a reversed-phase microemulsion method, and oxidizing the bletilla striata polysaccharide into dialdehyde bletilla striata polysaccharide by using sodium
