preparation example Construction

[0037] A preparation method for acrylic copper-plated-boron alloy conductive filaments, the specific steps comprising:

[0038] 1. The untwisted acrylic filaments are elasticized and twisted. The boiling water shrinkage of the processed filaments is ≤1.0%, the twist is 96Z / m, the strength is 28CN / Tex, and the elongation is 18%. The silk is helpful to the post-processing process, reducing the fuzz or messy yarn on the reel.

[0039] 2. The yarn bobbin after elastic and twisting is then wound onto the loose bobbin. The loose bobbin strives to be completely consistent with the weight of the yarn, the overall size and shape of the bobbin, and the density is controlled at 0.22Kg / dm 3 .

[0040] 3. Place the loose yarn bobbin in a closed container for degreasing treatment in the form of two-way pressure washing.

[0041] 4. Place the loose yarn bobbin in a closed container to micro-etch and roughen the surface of the fiber in the form of two-way pressure washing.

Embodiment 1

[0047] 1. The untwisted acrylic filaments are stretched and twisted on the puller. The shrinkage of the treated filaments in boiling water is ≤1.0%, the twist is 96Z / m, the strength is 28CN / Tex, and the elongation is 18%.

[0048] 2. The bobbin after elastic twisting is wound on the loose bobbin, and the density is controlled at 0.25Kg / dm 3 .

[0049] 3. Place the loose yarn bobbin in a closed container for degreasing treatment in the form of two-way pressure washing. After degreasing treatment, wash it three times with water to centrifugally dehydrate the yarn bobbin.

[0050] 4. Place the loose yarn bobbin in a closed container to micro-etch and roughen the surface of the fiber in the form of two-way pressure washing. After the treatment, wash the bobbin three times with water to centrifugally dehydrate the bobbin.

[0051] 5. Place the loose yarn bobbin in a closed container to activate the fiber under acidic conditions in the form of two-way pressure impregnation.

Abstract

The invention discloses a conductive acrylic filament plated with a copper-boron alloy and a preparation method of the conductive acrylic filament. An acrylic filament is taken as a matrix, bark-likesurface structure of the acrylic filament and -CN electronegativity are fully used, the acrylic filament is heated and impregnated under pressure in a closed basic copper sulfate solution for chemicalplating after being subjected to degreasing, roughening and activating, and the stable copper-boron alloy is formed on the acrylic surface, so that conductive treatment of the filament is realized. The prepared conductive acrylic filament has the advantages of easily controlled reaction, excellent electrical conductivity, high fiber affinity, lasting conduction property, excellent bacterial killing, deodorizing and shielding properties and better resistance to acid and base.

Description

technical field [0001] The invention relates to the field of functional fiber manufacturing, in particular to a method for preparing an acrylic conductive filament and its alloying. 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. The antistatic effect of conductive fiber is remarkable and long-lasting, and it is not affected by the humidity of the environment. The fiber with excellent conductivity is less than 10Ω·cm. At room temperature, the half-life of the charge on the surface of the fiber is very short. The conductive fabric made of fiber has excellent functions such as electric conduction, heat conduction, shielding, and electromagnetic wave absorption. It is widely used in conductive mesh and conductive work clothes in the electronics and electric power industries;...
