Embodiment 1
[0022] A wig fiber resistant to high temperature and easy to dye is made of the following raw materials in parts by weight: chitosan 40, epoxy resin 11, and graphene 4.
[0023] The epoxy resin is a glycidyl ester epoxy resin with an epoxy value of 0.34Eq / 100g, which can increase the transparency and brightness of the wig fiber and make the wig appear naturally black, bright and elegant.
[0024] The glycidyl ester epoxy resin is one or a combination of diglycidyl phthalate, diglycidyl terephthalate, and diglycidyl tetrahydrophthalate .
[0025] The graphene is bilayer graphene, which can be quickly mixed with modified chitosan.
[0026] A preparation method of a high temperature resistant and easy-to-dye wig fiber, comprising the following steps:
[0027] (1) Chitosan modification: add chitosan to sodium selenite solution with an amount 3 times the weight of chitosan, the concentration of sodium selenite solution is 40mg / L, gradually heat to 55°C, stir evenly and place In ...
Embodiment 2
[0033] A wig fiber resistant to high temperature and easy to dye is made of the following raw materials in parts by weight: chitosan 43, epoxy resin 12, and graphene 5.
