Embodiment 1

[0026] A preparation method for acrylic conductive filaments, comprising the following steps:

[0027] 1) The untwisted acrylic filament is shaped and twisted on the setting machine to form a shaped and twisted acrylic filament bobbin. After the shaped and twisted acrylic filament, the boiling water shrinkage of the filament is ≤1.5%, and the twist is 96t / m;

[0028] 2) After the shaped and twisted acrylic filament bobbin is processed by the winding machine, the acrylic filament is placed on the loose bobbin to make a loose bobbin, and the weight and shape of the loose bobbins are exactly the same;

[0029] 3) Place the loose yarn bobbin in a closed container, and then deoil it in the form of two-way pressure washing. After deoiling, it is centrifugally dehydrated to form a dehydrated and deoiled loose yarn bobbin;

[0030] 4) Place the dehydrated and deoiled loose yarn bobbin made in step 3) in a closed container, and perform impregnation and deposition of aniline monomer o...

Abstract

The invention discloses a preparation method of acrylic fiber conductive filament. The preparation method comprises the following steps: (1) placing twistless acrylic fiber filaments on a setting machine to carry out setting and twisting; (2) processing the set and twisted acrylic fiber filament yarn by a winding machine to convert the yarn into a loose yarn; (3) placing the loose yarn in an enclosed container to carry out deoiling and dehydrating through two-dimensional extrusion washing; (4) placing the deoiled and dehydrated loose yarn in an enclosed container, dipping and depositing aniline monomers on the fiber surface through pressured dipping; (5) placing the loose yarn dipped by the aniline in an enclosed container, carrying out two-dimensional pressured dipping on the loose yarn to oxidize and polymerize the aniline monomers on the fiber surface; (6) finally subjecting the loose yarn to pressure washing, dehydrating, drying, and oiling, and processing the loose yarn by a winding machine to convert the loose yarn into a finished product of acrylic fiber conductive filament. Through the steps mentioned above, the conductive treatment on acrylic fiber filament is well achieved, and the technology stability is good.

Description

technical field [0001] The invention relates to the technical field of fiber manufacturing, in particular to a method for preparing conductive fibers. Background technique [0002] In order to prevent static electricity and electromagnetic wave interference, people have developed various antistatic products, electromagnetic shielding materials and conductive fibers since the middle of the 20th century. Fiber with excellent electrical conductivity, less than 10Ω·cm. At room temperature, the half-life of the charge on the surface of the fiber is very short, and the static electricity can be eliminated in a very short time. The conductive fabric made of conductive fiber has excellent functions such as electric conduction, heat conduction, shielding, and electromagnetic wave absorption. It is widely used in electronics and electric power industries. Conductive mesh, conductive work clothes; electric heating clothing, electric surface, electric heating bandage in medical industr...
