Reinforcing tape for slide fastener and method for reinforcing end portion of fastener tape

摘要

Disclosed are a reinforcing tape (2, 20a, 20b) to be attached to each of the end portions of fastener tapes (1, 11a, 11b) of a separable slide fastener (10) intended for permitting attachment of a pin-and-socket separator and a method for reinforcing the end portions of fastener tapes (1, 11a, 11b) therewith. A reinforcing tape (2, 20a, 20b) composed of a reinforcing layer (4) and an adhesive layer (3) of a hot-melt adhesive having a melting point in the range of 110 DEG to 120 DEG C and a melt viscosity at 200 DEG C in the range of 1,000 to 2,000 poises is bonded to the end portion of the fastener tape (1) of the slide fastener through the medium of the adhesive layer (3) under heat and pressure. The preferred heat source is ultrasonic wave in case the reinforcing layer (4) is formed of resin film or a hot plate (heater) in case that layer is formed of plain weave fibers.
