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.

Abstract: The present invention intends to provide a waterproof slide fastener in which a synthetic resin film is fused to a fastener tape in order to prevent a perforation phenomenon that the synthetic resin film does not exist locally. A laminated synthetic resin film composed of low melting point resin layer having melting point of, for example, 100° C.-140° C. and high melting point resin layer having melting point of, for example, 150° C.-230° C. is fused to a surface or both surfaces of a pair of the fastener tapes with the low melting point resin layer being in contact with and opposing the fastener tape by heating with pressure. Fastener elements are mounted onto a side edge of the fastener tape and the laminated synthetic resin film is formed so as to protrude outward from the side edge of the fastener tape and a center point of coupling of the fastener elements.

Abstract: According to the fastener chain, method and apparatus for forming ends thereof, coil-shaped fastener elements as linear fastener elements are attached and sewed to side edge portions of a pair of fastener tapes with sewing yarns as fixing yarns while a core thread is inserted through the fastener elements. The coil-shaped fastener elements are cut off at leg portions, each of which is in contact with the fastener tape, at ends of the fastener elements, so that cut end portions are formed. These cut end portions are pushed inward of the side edge portions, and then, the leg portions and inverted portions thereof are fused to the fastener tapes by heating. As a result, a form of each end of the fastener elements is stabilized, so that the resultant slide fastener is good in safety.

Abstract: A core cord is inserted into coil-shaped fastener elements made of thermoplastic resin, and the fastener elements are sewn onto a fastener tape by multi-thread chain stitch. Yarn mainly made of thermally meltable synthetic fiber is used for looper thread of multi-thread chain stitch, while yarn of fiber which is not or less meltable is used for needle thread. Entangling points of the looper thread and the needle thread are disposed on the core cord. The looper thread is thermally melted to form melted portions where the looper thread and the needle thread entangle with each other at the entangling points. As a result, melted portions which have become monofilamentary are formed on the fastener elements or no sewing yarn is on the fastener elements due to thermal melting. Thus, there is no fear of cutting of the sewing yarn due to sliding of a slider and the slide fastener is abrasive resistant.

Abstract: By fusing reinforcing tapes with bottom end attaching portions of fastener tapes by pressurizing heating means with different pressures (i.e., high and low), thus weakening of attaching portions can be prevented. Core threads are fitted to side edges of fastener tapes to form core portions. Reinforcing tapes formed of thermoplastic elastomer film or thermoplastic resin film are fused to wrap tape end portions including the core portions so as to form the bottom end attaching portions. The reinforcing tapes fused the core portions and vicinity portions to the fastener tapes with a low pressure and at tape main body portions to the fastener tapes with a high pressure, thereby making the core portions and the vicinity portions flexible and thick and making the tape main body portions stiff and thin to form stepped portions. The stepped portions are positioned outside flanges of a slider.

Abstract: The present invention provides a warp-knit slide fastener in which a fastener element row can be easily knitted into and attached stably and firmly on a fastener tape, and fastener elements of the fastener element row are not separated from each other due to pushing up of a fastener face.The successive fastener element row is knitted, simultaneously with knitting of the fastener tape, into a fastener element attaching portion at longitudinally side edge portion of the fastener tape, and is fixed by two wales or more of fixing chain stitch yarns. Respective needle loops of the respective fixing chain stitch yarns push respective element leg portions of the successive fastener element row from above toward a foundation structure. Respective sinker loop groups form a part of the foundation structure on which the successive fastener element line is disposed. Warp in-laid yarns are warp inserted through at least a part of sinker loops of the sinker loop groups while being intermingled.

Abstract: The present invention provides a slide fastener which can exhibit a clear retroreflective phenomenon by providing retroreflective functions to filament fastener element rows and mounting threads. The retroreflective filament slide fastener of the invention includes filament fastener element rows formed from wire rods made of thermoplastic resin which have retroreflective layers formed by covering surfaces of the filament fastener element rows with retroreflective paint. A synthetic fiber thread is used as the mounting thread for mounting the filament fastener element rows to a fastener tape. The mounting thread is provided with a retroreflective layer by covering a surface of the synthetic fiber thread with the retroreflective paint, or winding or twisting a retroreflective film around or together with the synthetic fiber thread. Thus, the filament fastener element rows and the mounting thread which are the most conspicuous in the slide fastener can easily exhibit the retroreflective phenomenon.
