Problems solved by technology

Electroless plating requires the use of expensive palladium chloride, but because the stability of the chemical plating solution is difficult to control, it will bring quality uncertainty in large-scale production; direct vacuum coating on the surface of textiles, due to the formation of shielding at the intersection of textiles, There will be plating vacancies in the shielded parts, so more metal needs to be deposited during electrodeposition to cover the intersection parts to form a complete metal film layer. Based on 80um textiles, the metallized textiles with a square rent of 0.03 ohms can be achieved. Electroless plating plus electroplating requires 23g / m 2 , Vacuum plating requires 28g / m 2

preparation example Construction

[0021] The invention provides a method for preparing textile metallization, which specifically comprises the following steps:

[0022] (1) Coarsening: use the woven fabric of chemical fiber formed by warp weft weaving or knitting as the textile, and then according to the specific type of chemical fiber, choose to immerse in hydrochloric acid or sodium hydroxide solution for roughening until the surface is microscopically rough;

[0023] (2) Neutralization: After the roughened textiles in step (1) are washed with water, they are selected to be immersed in sodium hydroxide or sulfuric acid solution for neutralization according to the specific category of chemical fibers;

[0024] (3) Colloidal solution impregnated with metal ions: After the textiles neutralized in step (2) are washed again, immerse in the colloidal solution containing metal ions for 0.5-1.5 minutes, after the surface absorbs the colloid, dry and solidify for 45-50 hours , temperature 80~100 ℃; The colloidal solu...

Embodiment 1

[0032] Embodiment 1 adopts aqueous polyurethane resin as the processing method of colloidal solution, and concrete method is as follows:

Abstract

The invention belongs to the field of textile metallization processing, and specifically discloses a preparation method of textile metallization. According to the method, woven fabrics of chemical fibers formed by warp and weft weaving or knitting are selected, and a textile surface is subjected to roughening, neutralizing, immersing in a metal ion-containing colloidal solution, and solidifying toform a material containing a solidified layer of metal ion colloid on the surface, and then vacuum coating and metal electrodepositing are conducted to form an all-directional conductive textile. After a cross-section of the textile is bonded, a metal coating is formed to form an all-round conductor. The method utilizes a bonding effect of a metal ion-containing colloidal solution to fill gaps caused by shielding of the cross-section of the textile, so that subsequent metallization processing can reduce the amount of metal used, improve production efficiency, save metal resources and reducesenergy consumption.

Description

technical field [0001] The invention belongs to the field of textile metallization processing, and in particular relates to a preparation method of textile metallization. Background technique [0002] At present, with the rapid development of smart display technology, soft conductive shielding materials with light weight and thin thickness have become the direction of demand for smart devices. Traditional metallized textiles are the main varieties of soft electromagnetic shielding, mainly through roughening, sensitization, electroless plating and then electroplating on the surface of textile materials, and direct vacuum coating on the surface of textiles and then electroplating. Electroless plating requires the use of expensive palladium chloride, but because the stability of the chemical plating solution is difficult to control, it will bring quality uncertainty in large-scale production; direct vacuum coating on the surface of textiles, due to the formation of shielding at...
