Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2018/018821
Kind Code:
A coated abrasive net, comprising a substrate (210), and an adhesive layer (204) and an abrasive layer (206) on one surface of the substrate (210). The substrate (210) is a knitted or machine-woven elastic fabric having a dense arrangement of warp fibers, no apparent holes, and a relatively smooth surface. The substrate can be expanded in the weft direction under a specific pulling force condition to transform from having a smooth surface to having a net structure having holes (203). The weft-direction expansion is not performed during manufacturing of the substrate, but during manufacturing of the net-backed coated abrasive product (211) instead. Also disclosed is a manufacturing method of a net-backed coated abrasive product. In the manufacturing method of the present invention, coating is performed on a substrate of woven fabric relatively compact or having no obvious net holes, and then the substrate is stretched in the weft direction to expand into a net. By using the relatively compact substrate, the present invention effectively improves coating uniformity and smoothness of the substrate, and reduces control difficulties of the coating operation, thus overcoming the difficulties of conventional manufacturing methods in which a holed substrate is directly used as a base.
