Abstract
A method for reinforcing fabric edges to prevent raveling or fraying of a release liner fabric during cutting and subsequent use. The method is carried out by coating the yarn crossovers with a flexible, thin film of a radiation polymerized resin and then curing the coating system at high production speeds. The fabric is cut in those areas where the cured coating is applied, thereby providing a band or border of cured resin of sufficient width to prevent raveling of the fabric edge. The method is particularly suitable for the fabrication of release liners used for the protection of rubber sheeting for manufacturing automobile tires.
