I believe they used to use stainless steel in the fabric.

This has caused both internal and external issues, and we've yet to identify the source. It's definitely formed wire, with a thickness ranging from 7 to 10 microns, and up to 3 mm in length. Our automated optical inspection stations can only reliably detect widths of 12 to 15 microns. I've checked the internet in an attempt to find common applications of this wire. I've found two, and they were for ultra-fine filters and stencil screen mesh. We've investigated (I think) all of our machinery that would utilize filters this small and have found no such usage. I've also checked every stencil in our plant, and all of our mesh material is some type of a plastic compound. Do you have any idea where this stainless steel might be coming from? Any suggestions would be sincerely appreciated!
