Abstract
This two-layer weave for non-woven fabric fulfills the required characteristics of weaves for unwoven fabrics such as stiffness while increasing the effect of preventing adhesion of fibers, etc., and maintains the antifouling effect despite surface wear occasioned by long-term use in industrial processes involving nonwoven fabric. In this weave for a nonwoven fabric, a top weave constituted from top warp threads and top weft threads and a bottom weave constituted from bottom warp threads and bottom weft threads are bonded by means of weft-binding threads. The weft-binding threads are woven together so as to bond internally, and the top warp threads and the top weft threads are characterized by being formed from a fluororesin.
