Problems solved by technology

The former metal fiber is not resistant to folding and feels rough; the latter fabric has a poor appearance and cannot meet the wearing requirements
Moreover, although the fabric has a high electromagnetic shielding effect after vacuum plating, electroplating or chemical plating, a careful analysis of the fabric shows that the metal plating only covers the surface of the fabric, and each single filament inside the warp and weft does not All metal layers are plated, so the fabric is directly processed by vacuum plating, electroplating or chemical plating to further improve the electromagnetic shielding effect, which is subject to certain restrictions

Embodiment 1

[0080] The first step is to select nylon 66 filaments and wash them with detergent solution to remove oil and dirt;

[0081] In the second step, the fiber filaments are arranged neatly and wound into a shaft;

[0082] The third step is to activate the fiber filaments. A resin layer containing precious metals is formed on the surface of the fiber filaments by means of padding activation solution. The activation solution contains 0.2% silver nanoparticles, 0.3% polypyrrolidone, 3% polyurethane, 0.01 For the dispersion system of %JFC, the temperature of the activation solution is 30°C, the excess rate is 70%, and it is dried in an oven at a temperature of 170°C and a drying time of 10 minutes;

[0083] The fourth step, electroless copper plating, using sodium hypophosphite as a reducing agent, pH 9, bath temperature 65°C, immersion plating time 5 minutes, the bath contains:

[0084] Copper sulfate 10g / L

[0085] Nickel sulfate 0.5g / L

[0086] Citric acid 20g / L

[0087] Boric ...

Embodiment 2

[0103] The first step is to select acrylic filaments and wash them with a detergent solution to remove oils and dirt;

[0104] The second step to the seventh step are the same as example 3;

[0105] The eighth step, blending 5% conductive staple fiber, 35% polyester, and 60% wool to make 48 yarns;

[0106] The ninth step, weaving and dyeing and finishing process to make permanent antistatic fabric.

[0107] The prepared antistatic fabric was tested, and the static voltage half-life was 1.8 seconds.

Embodiment 3

[0109] The first step is to select polyester filaments and wash them with detergent and alkaline solution to remove oil and dirt;

[0110] In the second step, the fiber filaments are arranged neatly and wound into a shaft;

[0111] The third step is to activate the fiber filaments. A resin layer containing precious metals is formed on the surface of the fiber filaments by means of padding activation solution. The activation solution contains 0.2% palladium nanoparticles, 0.3% polyvinyl alcohol, and 2.5% acrylate , 0.01% JFC dispersion system, the temperature of the activation solution is 40°C, the excess rate is 65%, and it is dried in an oven at a drying temperature of 190°C and a drying time of 6 minutes;

[0112] The fourth step is electroless copper plating, using formaldehyde as a reducing agent, pH 12.5, bath temperature 45°C, immersion plating time 2 minutes, copper plating bath contains:

[0113] Copper sulfate 15g / L

[0114] Sodium Potassium Tartrate 15g / L

[0115]...

Abstract

The invention relates to an antistatic, conductive and electromagnetic shielding textile and a preparation method thereof, being characterized in that fiber filament is firstly processed by electroless plating copper in a way of continuous proceeding and then processed by electrolytic tinning to prepare conductive filament; then, the conductive filament is cut into conductive short fiber which is processed by pure spinning or blend spinning with other common textile fibers to be made into yarn, and the antistatic, conductive and electromagnetic shielding textile can be prepared by fabric manufacture as well as dyeing and finishing; or the conductive short fiber is blended with other common textile fibers and then processed into non-weaving cloth by pinprick or spunlace. The textile prepared by the invention has beautiful appearance and soft feel, and is safe to the skin.

Description

technical field [0001] The invention relates to an antistatic, conductive and electromagnetic shielding textile and a preparation method thereof, belonging to the technical field of functional textiles. Background technique [0002] The static electricity generated by clothes will bring a lot of inconvenience to people's life, and even bring safety hazards in some special occasions; the popularization of mobile phones, home appliances, computers and other electrical appliances has caused extensive electromagnetic wave pollution. Therefore, antistatic, conductive and electromagnetic shielding textiles have a broad market. At present, the methods for preparing antistatic, conductive and electromagnetic shielding textiles mainly include: (1) processing with metal fiber blending; (2) directly processing fabrics by vacuum plating, electroplating or chemical plating. The former metal fiber is not resistant to folding and feels rough; the latter fabric has a poor appearance and ca...
