发明名称 Sheet material used to form portions of fasteners
摘要 A method for forming a sheet material adapted to be cut into smaller pieces to form portions of a fastener. The method comprises providing a backing laminate comprising a layer of base material and a sealing layer of heat softenable polymeric material along a back surface of the base material; stitching a plurality of yarns through the base material to form loops projecting from a face surface of the base material and locking portions of the stitch adjacent the back face of the base material; and heating the polymeric material to adhere it to the locking portions of the stitches. The sheet material can then be used if loops are desired, or the loops can be cut to form hooks or heated to form headed projections on the sheet material.
