Abstract
An object of the present invention is to provide a linear slide fastener capable of maintaining a stabilized condition in which an attachment yarn for attaching a fastener element is never out out by abrasion due to a contact with other object or sliding of a slider. A coil-like or zigzag-like linear fastener element row is attached to a fastener tape with a multi-filament attachment yarn or a sewing yarn of double lock sewing system. Then, synthetic resin material having adhesive property is applied to an entangled portion between a looper yarn disposed on the linear fastener element row and a needle yarn so as to permeate the entangled portion and harden. Consequently, the attachment yarn is coated and fixed with the synthetic resin material, As the attachment yarn, a weaving yarn or a warp knitting yarn is used. The synthetic resin material is applied to the entangled portion or an intersecting portion so as to permeate them. As a result, a strong, abrasion resistant yarn can be formed and the yarns are bonded with each other so as to achieve a stabilized condition which provides an excellent performance for guiding a slider.
