Problems solved by technology

[0003] The technical problem to be solved by the present invention: Aiming at the disadvantages of poor durability of the prepared antistatic fiber and easy breakage during the spinning process due to the poor compatibility between the antistatic agent and the matrix, a method is provided by subjecting montmorillonite to high temperature And mechanical activation, supplemented with copper sulfate and tapioca starch, the surface was modified, and then the wheat leaf at the jointing stage was used as the induced nutrient source, and zinc chloride was used as the inducer to induce the culture of Pseudomonas putida. Obtain the required strains, induce the sieved particles through the strains, increase the compatibility with the matrix, and then mix with tartaric acid, calcium nitrate, antimony oxide, etc. Method for preparing high-strength antistatic fiber by mixing materials such as ethylene glycol diformate

Abstract

The invention discloses a preparation method of a high strength antistatic fiber and belongs to the technical field of antistatic fiber preparation. The preparation method comprises carrying out high temperature and mechanical activation on montmorillonite, modifying the surface of the montmorillonite through copper sulfate and tapioca starch as aids, carrying out induced culture on pseudomonas putida through wheat leaves in an elongation stage as an induction nutrient source and zinc chloride as an inducer to obtain a required strain, inducing sieved particles through the strain so that compatibility with a matrix is improved, and then mixing the particles, tartaric acid, calcium nitrate and antimony oxide so that the antistatic properties are improved and an antistatic agent is obtained, and mixing the antistatic agent and polyethylene glycol terephthalate to obtain the high-strength antistatic fiber. The preparation method has simple processes, the antistatic agent has good compatibility with the matrix, and the antistatic fiber has antistatic durability, the breaking phenomenon is avoided in spinning and high strength is obtained.

Description

technical field [0001] The invention relates to a preparation method of a high-strength antistatic fiber, which belongs to the technical field of antistatic fiber preparation. Background technique [0002] Antistatic fiber is a kind of chemical fiber that is not easy to accumulate static charge. Antistatic fibers mainly include antistatic polyester, antistatic acrylic, and antistatic polypropylene. At present, there are three main methods for preparing antistatic fibers: one is to immerse fibers or fabrics in antistatic agents, or to coat the surface with surfactant antistatic agents. This method is simple to operate, but the obtained antistatic After the electrostatic fiber is washed or dry-cleaned, the antistatic agent is easy to fall off, and the antistatic durability is poor; the second is to add carbon black, metal or metal oxide during the preparation of the fiber to make antistatic fiber. The antistatic fiber has stable performance, excellent effect, strong durabili...
