What is conductive fabric?
The so-called conductive cloth is made of fiber cloth that is pre-processed and then electroplated with a metal coating to make it have metallic properties. It can be divided into: plated Nickel conductive cloth, gold-plated conductive cloth, silver-plated conductive cloth, carbon-plated conductive cloth, aluminum foil fiber composite cloth. There are plain and grid distinctions in appearance; followed by anti-fouling conductive cloth, flame retardant adhesive conductive cloth, hot melt adhesive conductive cloth cloth, conductive adhesive conductive cloth, plaid conductive cloth, non-woven conductive cloth, etc.

The main function of conductive cloth
It has good conductivity and shielding effect. It can be used as wire, FFC, EPC, and EMI laboratory auxiliary materials; it is mainly used in gaps in chassis or other equipment to provide low-impedance conductive connections. It is widely used in the electrical and electronic wire industries for shielding against electromagnetic radiation.
Then there are several reasons why lint is produced during the die-cutting process of conductive cloth:
1. Related to the knife mold:
The knife mold It is necessary to use a sharp knife mold. It is recommended to use a mirror knife, an etching knife or a carving knife (the hardness needs to be dealt with) to die cut and stamp. If it is an ordinary knife mold, a knife needs to be installed at an equal distance from the joint on the knife mold. , can avoid the phenomenon of lint!
2. It depends on whether the product has spacing:
Weave the structure from the conductive cloth base material Generally speaking, if the product is typesetting and die-cut without spacing, the glue will “stick back”. During the die-cutting process, the glue will accumulate on the edge of the die and the cloth on the edge of the conductive cloth will be taken out together when die-cutting. In this way, If burrs appear, it is generally recommended that this product be die-cut with spaced layout. If this phenomenon occurs, dry release agent can be sprayed on it, which can alleviate the problem for a period of time.
3. It is related to the density of the conductive cloth material
Conductive cloth is a fiber cloth material and its density It is relatively thick, and the glue cannot penetrate into it. There will be a lot of lint when die-cut, and it is irregular. At the same time, new lint will appear during the waste discharge and packaging process.
4. With Regarding the bottom paper:
General paper is not hard enough and relatively brittle. If you want to break it, it is recommended to use a release film as the bottom paper, and the effect may be better!
5. It is related to waste discharge or die-cutting speed:
The angle of waste discharge needs to be Set it in a 60-degree direction and adjust the die-cutting speed to the optimum, the effect will be better!
It may also be related to the texture of the conductive cloth/softness and hardness of the mold adjustment base/foam cushioning the mold.
End: These are common problems and solutions for conductive cloth. Of course, with the continuous innovation of die-cutting processes and mechanical equipment, I believe that the future The processing technology can save materials, be simpler, and cause fewer problems.
