What is the reason for the generation of lint during the die-cutting process of conductive fabric?

01

What is conductive cloth?

The so-called conductive cloth is made of fiber cloth that is pre-processed and then electroplated with metal coating to make it have metallic properties. It can be divided into: nickel-plated conductive cloth, gold-plated conductive cloth, silver-plated Conductive cloth, carbon-coated conductive cloth, aluminum foil fiber composite cloth. There are plain and grid distinctions in appearance; secondly, there are antifouling conductive cloth, flame retardant adhesive conductive cloth, hot melt adhesive conductive cloth, conductive adhesive conductive cloth, and plaid conductive cloth. 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.

There are several reasons why lint is produced during the die-cutting process of conductive cloth:

1. Related to the die:

The die needs to be sharp. 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 punch. If it is an ordinary die, It is necessary to install a knife at an equal distance from the joint on the knife mold to avoid lint!

2. It depends on whether the product has spacing:

From the weaving structure of the conductive cloth base material, if the product is typeset and die-cut without spacing, the glue will “stick back”. During the punching process, glue will accumulate on the edge of the die and when punching again, the cloth on the edge of the conductive cloth will come out together, so that burrs will appear. It is generally recommended that this product be die-cut with spaced layout and if it appears To prevent this phenomenon, you can spray a dry release agent to relieve it for a period of time.

3. It is related to the density of the conductive cloth material

The conductive cloth is a fiber cloth material with a relatively thick density, and the glue cannot penetrate into it, so there will be more hair when it is die-cut. Silk, and there is no pattern. At the same time, new wool will appear during the waste discharge and packaging process.

4. Related to the bottom paper:

General paper is not hard enough and brittle. It is recommended to use a release film as the backing paper for punching, and the effect may be better!

5. It is related to the waste discharge or die-cutting speed:

The waste discharge angle needs to be 60 degrees and the die-cutting speed is appropriately adjusted to the best, 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 padding the mold.

End: These are common problems and solutions for conductive cloth. Of course, with the continuous innovation of die-cutting technology and mechanical equipment, I believe that the subsequent processing technology will be more material-saving, simpler and more convenient. The fewer problems arise.
