Inquiry about Optical-Grade Microfiber Fabric NEW

I am sourcing optical-grade microfiber fabric for warp-knitting applications. The fabric must meet specific technical specifications: knitting should be warp-knit tricot, with machine gauge options of E28, E32, E36, or E40. Filament denier must range from 0.10 to 0.15 denier per filament, and fiber type should be split microfiber. Composition needs to be 80% polyester/20% nylon or 70/30. Finishing must exclude suede, brushing, and sanding, with a smooth optical-grade non-pile surface. I require details on the raw yarn supplier and a 30x30 cm raw fabric sample for evaluation. If the specifications match, I will order samples immediately.
