Abstract
The invention discloses a graphene / flax composite fiber preparation method, which comprises: 1) preparing a compound enzyme refining agent; 2) pre-treating flax fiber; 3) refining, wherein the prepared flax fiber is immersed into the compound enzyme refining agent and soaked, and washing and dewatering drying are performed to prepare the modified flax fiber; and 4) uniformly mixing the modified flax fiber and graphene fiber. According to the present invention, the flax fiber is mixed with the graphene fiber, such that the strength and the toughness of the blended yarn of the flax fiber can be improved, and the resistivity of the mixed fiber achieves 10-103 [omega].m while the resistivity of the conventional fiber is about 10-14 [omega].m, wherein the resistivity is improved by more than 10 magnitude orders; the flax fiber is subjected to the modification treatment with the biological enzyme so as to improve the dyeing effect of the yarn; and the impurity pectin removing effect and the impurity lignin removing effect are good with the selected compound enzyme refining agent, and the chelating agent is increased so as to further enhance the impurity removing effect of the compound enzyme.
Description
technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of graphene / flax composite fiber. Background technique [0002] Conductive fibers have always been a research hotspot for functional fibers, generally referring to resistivity less than 10 8 The fiber of Ω·cm has the functions of conduction, electric heating and anti-electromagnetic radiation, and is usually concentrated in the fields of anti-static clothing or anti-electromagnetic radiation clothing used in special occasions. [0003] The main methods for the manufacture of conductive fibers include: one is to coat the surface of conventional fibers with conductive components, and the other is to mix conductive materials with fiber raw materials and make conductive fibers by spinning. The method of coating the conductive layer on the surface of the fiber is to coat the conductive material containing metal, carbon black or metal compound on the ...
