Embodiment 1

[0034] DETAILED DESCRIPTION Example 1. Preparation of conductive polyester fabric

[0035] 1. Wash polyester fabric with detergent solution at room temperature, then rinse with running water, dry, degrease and descale. fiber images such as figure 1 shown.

[0036] 2. Plasma treatment: The washed polyester fabric is treated in a low temperature plasma system of oxygen. The processing conditions are: power 200W, pressure 40Pa, and time 20 minutes. fiber images such as figure 2 shown. According to the contact angle measurement, the contact angle of the polyester fabric to water before treatment is 140.6°, which is a hydrophobic material and cannot be treated by electroless plating. After treatment, the polyester fabric can completely absorb water within 10.8 seconds.

[0037] 3. Sensitization treatment: The plasma treated polyester fabric is immersed in Sncl 2 : 20 g / l, 37% HCl: 120 ml / l in the treatment solution. The treatment time was 15 minutes, and...

[0046] The resistivity of the conductive polyester fabric made as above is 0.3Ω / cm 2 . Example 2. Preparation of conductive cotton fabric

[0047] 1. Wash cotton fabrics with detergent solution at room temperature, then rinse with running water, dry, degreasing and descaling.

[0048] 2. Plasma treatment: The washed cotton fabric is treated in a low temperature plasma system of oxygen. The processing conditions were: power 50W, pressure 70Pa, and time 10 minutes.

[0049] 3. Sensitization treatment: immerse plasma-treated cotton fabrics containing Sncl 2 : 20 g / l, 37% HCl: 120 ml / l in the treatment solution. Treatment time was 15 minutes at room temperature. Then rinse with distilled water.

[0050] 4. Activation treatment: Immerse the sensitized cotton fabrics containing PdCl 2 : Activation treatment in 1.0 g / l, 37% HCl: 10 ml / l treatment solution. The treatment time was 20 minutes at room temperature. Then rinse with distilled water.

Abstract

The present invention relates to the preparation of conductive fabric and is especially plasma treatment process of conductive fabric with coated conducting metal layer on the surface and thus electrothermal, antistatic, electromagnetic shielding and other functions. The process includes the steps of: defatting and decontaminating substrate materail, electrochemical activating, metallizing and surface treatment as well as characterized low temperature plasma treatment step before the electrochemical activating step to etch the surface of fabric fiber at the conditions of 20-400 W power and 1-100 Pa air pressure and for 40 min. The said etching effect on the surface of fabric raise the fastness of metal layer on the fabric.

Description

technical field [0001] The invention belongs to the field of preparation methods of conductive fabrics, and in particular relates to a conductive fabric treated by plasma, which is a kind of conductive fabric by plating a metal conductive layer on the surface of the fabric to make the fabric become a conductive fabric with functions such as electric heating, anti-static, electromagnetic shielding and the like. preparation method. Background technique [0002] Conductive fabric is made by firmly plating a layer of metal on the surface of the fabric to make it have good electrical conductivity, but also maintain some of the original physical characteristics of the fabric. The fabric can thus be glued, cut or sewn, etc., to produce different geometries. The conductive fabric has electric heating function after the safe voltage is applied, and its conductivity is anti-static, and it is an efficient electromagnetic shielding material. This conductive fab...
