Problems solved by technology

[0003] The technical problem to be solved by the present invention: for the conductive polyester fiber prepared by compounding polyaniline, due to the poor water absorption of polyester fiber, it is difficult to effectively absorb aniline, and the reaction liquid is difficult to enter the inside of the fiber, and the distribution is uneven, resulting in poor compactness of the obtained material and durable electrical conductivity Due to the disadvantages of reduced resistance and difficult processing and molding, a kind of mussel meat is hydrolyzed into polypeptides by alkaline protease, and the polypeptides are used as complexing agents to react with zinc chloride solution to form complexes for later use, and then take polyester fiber alkali Soak to form pits on the fiber surface, then soak the fibers with beef extract peptone medium culture solution, then use yeast to adsorb and grow on the fiber surface and pits, modify the fibers, and mix the modified fibers with the spare complex Mixing, the yeast on the surface of the fiber consumes the polypeptide in the complex, so that the zinc ions are released, adsorbed on the surface of the yeast, and then reduced with potassium dihydrogen phosphite solution as a reducing agent, so that metal zinc grows on the surface of the fiber and the grooves. The long-term conductive polyester fiber is made by drying in the pit, which effectively solves the problems of poor compactness, easy falling off of conductive material, and reduced conductive durability.

Abstract

The invention discloses a preparing method of a long-acting and conductive polyester fiber and belongs to the technical field for preparing polyester fiber. The mussel meat provided in the invention is in enzymolysis into polypeptide by alkaline protease; polypeptide matter is taken as complexing agent which reacts with zinc chloride solution to form complex for standby; the polyester fiber is taken and soaked in alkali, so that a pit is formed on the fiber surface; the fiber is soaked by beef extract-peptone medium nutrient solution, and then the fiber is absorbed and grown in the fiber surface and pitby saccharomycetes to modify the fibers; the modified fiber is mixed with the standby complex; the zinc ion can be relieved by the polypeptide in the saccharomycetes consumption complex on the surface of the fiber to be absorbed on the saccharomycetes surface; and then the potassium dihydrogen phosphate solution is taken as the reducing agent to reduce the fiber; the metal zinc can grow in the fiber surface and pit, and then the metal zinc is dried to obtain the long-acting and conductive polyester fiber. The problems of poor density and reduced conductive durability are effectively solved. The preparation steps in the invention are simple, the obtained polyester fiber is easy to be processed and formed with high conductive durability.

Description

technical field [0001] The invention relates to a preparation method of long-acting conductive polyester fiber, which belongs to the technical field of polyester fiber preparation. Background technique [0002] Polyester has superior physical and mechanical properties such as high strength, good elasticity, and high rigidity, as well as acid resistance and corrosion resistance. It has become the most widely used chemical fiber at present. However, polyester molecules are bound by covalent bonds and cannot It also cannot transmit electrons, so it is easy to generate and accumulate charges during friction. In addition, there are few polar groups in polyester fibers, and the hydrophobicity is large, which is easy to generate static electricity. The generation of static electricity makes the fibers easy to pilling, absorb dust, and stain. The interference is obvious, which will cause clothing to entangle and absorb dust, affecting wearing. When static electricity accumulates to...
