METHOD FOR PREVENTING MESH SLIPPAGE OF FLAT YARN CLOTH AND THE SAME FLAT YARN CLOTH

摘要

PURPOSE:To prevent mesh slippage and fray in cut ends without losing flexibility by subjecting a flat yarn cloth consisting of thermoplastic flat yarns to pressurizing ultrasonic treatment and fusing the intersecting points of warp and weft yarns. CONSTITUTION:A flat yarn cloth prepared by using flat yarns formed from a thermoplastic resin is passed between a rotating roll having a fusing pattern provided on the surface thereof and a cone for pressing and urging in the direction of the rotating roll and transmitting ultrasonic waves to ultrasonically fuse the intersecting points of warp and weft yarns.
