Abstract
The present invention provides a surface fastener having a high durability, in which an engaging element yarn for forming loop-like or hook-like engaging elements is fixed firmly to a foundation fabric in a simple configuration. In a surface fastener foundation fabric woven with warps and wefts, the engaging element yarns for forming the loop-like, hook-like or mushroom-like engaging elements are woven into the foundation fabric at a predetermined interval, and cross-woven warps are woven with the engaging element yarns to fix the engaging element yarns to the foundation fabric at before and after each of loop portions of the engaging element yarns. Further, warps of thermal melting yarns are used as the cross-woven warps which are melted so that the engaging element yarns may be welded to the foundation fabric. Consequently, a surface fastener having good feeling and is excellent in strength and flexibility is obtained.
