Abstract: An elastic nonwoven laminate that contains an elastic film laminated to one or more nonwoven facings is provided. The nonwoven facing contains a conventional polyolefin and can also contain a polyolefin-based plastomer. The laminate is activated by grooving to decouple the nonwoven facing from the elastic film. To reduce fiber-pull out that can result due to activation by grooving, the laminate can be post-bonded at room or elevated temperatures and a specific range of pressures to compact the fibers of the facing and minimize fiber pull-out/fuzziness while not sacrificing the softness, elasticity, and feel of the laminate.

Abstract: A system and method for welding edge seams at the edges of fabric is presented. A method begins by lowering a fabric pre-fold bar onto a piece of fabric. A pre-aligned portion of the fabric is pushed on top of the pre-fold bar so that the pre-fold bar is between the portion of fabric on top of the fabric pre-fold bar and other fabric below the pre-fold bar. The fabric on top of the fabric pre-fold bar is folded edge fabric and fabric not on top of the fabric pre-fold bar is not folded edge fabric. A folded edge is formed between these two sections of fabric. The method pinches some of the fabric at the folded end and then pulls the folded edge fabric off of the fabric pre-fold bar. After that, the method welds at least some of the folded edge fabric to the not folded edge fabric.
