Abstract
A process for angularly sueding a textile web containing fill and warp yarns with the steps of: supplying the web, controlling the tension of the web, engaging the web with at least one diamond-coated abrasive treatment roll disposed at an abrasion angle, rotating the treatment roll at a surface speed different from that of the web, and taking up the supplied web. A preferred embodiment comprises a pair of spaced treatment rolls disposed at an abrasion angle, and rotating in opposite directions relative to the web. The related apparatus for this specific process is also provided.
Claims1
A substantially streak-free fabric wherein said fabric has been treated through a sueding process by at least one abrasive roll exhibiting a variation in abrasive grit size on the surface of said roll, wherein said fabric exhibits a sueding treatment at an angle of at least 5 degrees and at most 60 degrees from the warp direction of said fabric, and wherein the fill strength of said fabric is greater than half the fill strength as measured for the same fabric prior to said sueding process.
