摘要:
The present invention provides a stretchable fastener stringer for a slide fastener in which an element row is attached to a stretchable fastener tape, the slide fastener being capable of preventing occurrence of chain breaking even when coupled element rows receive pushing force and capable of stably maintaining a coupled state of the element rows. The stretchable fastener stringer according to the present invention includes a fastener tape (2) having a tape main portion (2a) and an element attaching portion (2b) and a continuous fastener element (3) which is attached to the element attaching portion (2b). The fastener tape (2) has stretchability due to an elastic yarn (8) being combined by weaving or knitting and the fastener element (3) includes a coupling head (3a), upper and lower leg portions (3b, 3c) which are extended from the coupling head (3a) and a connecting portion (3d) which connects the upper and lower leg portions (3b, 3c) therebetween of adjacent fastener elements (3). In this fastener stringer (1), a value of a bulging ratio (= mountain length H / leg portion length d) which is the ratio between a dimension of the coupling head (3a) in the tape longitudinal direction (= mountain length H) and a dimension of the upper and lower leg portions (3b, 3c) in the tape longitudinal direction (= leg portion length d) is set to be larger than 1.80 and not larger than 2.33.

In a fastener stringer (10, 50) of the invention, a continuous fastener element (20) includes a plurality of fine projections (31) disposed on a circumferential surface of a monofilament (30) continuously along a length direction of the monofilament (30). Moreover, at least the projections (31) disposed on the upper and lower leg parts (23, 24) are twisted with respect to an extension direction of the upper and lower leg parts (23, 24), and a plurality of the projections (31) disposed on the upper leg part (23) or the lower leg part (24) in a twisted state face the same direction. Due to this, a larger number of projections (31) can appear on an exposed surface of the fastener element (20), light can be diffused and reflected from these projections (31), and the luster of the monofilament (30) can be stably reduced or removed. Moreover, it is possible to prevent the strength of the monofilament (30) from locally decreasing and to prevent deterioration of the operability of a slider (8).

There is provided a slide fastener and a method for manufacturing a slide fastener, in which the fastener element rows can be both dyed and matted and the manufacturing cost of the slide fastener can be reduced. A slide fastener is provided with: a pair of fastener tapes (20); a pair of fastener element rows (30) provided respectively on the opposing tape-side edges (20a) of the pair of fastener tapes (20) and having a plurality of fastener elements (31); and a slider (40) configured to engage and disengage the pair of fastener element rows (30) with and from each other. Each of the fastener element rows (30) is comprised of a monofilament (50) which is made of synthetic resin. The monofilament (50) has, on the surface thereof, a surface layer (51) which can be colored with dyes. A roughened surface (52) having a number of concaves is formed on the surfaces of the surface layer (51).

A double coil layer zipper having each coil-supporting bigger filter cord thereof compacted to provide an extended side edge that is stopped against the coil heads of the respective series of coils, and the coil body of each coil of the interlocking series of teeth thereof configured to provide a recessed face and two opposing side flanges that enhance the locking tightness between the left-handed and right-handed series of coils. The zipper slider of the double coil layer zipper has a front balance tongue for guiding the left-handed and right-handed series of coils between the jointing position and the opening position smoothly.

Provided is a continuous fastener element (10) formed by molding thermoplastic synthetic resinous monofilament (37) in a coil shape or a zigzag shape, the continuous fastener element including: a coupling head (11); upper and lower leg portions (12, 13) which extend from the coupling head (11) in the width direction; and a connecting portion (14) which connects the leg portions (12, 13) adjacent to each other in the longitudinal direction, wherein surfaces of the coupling head (11), the leg portions (12, 13), and the connecting portion (14) are each formed as a rough surface with a plurality of recesses. Furthermore, a head surface of the coupling head (11) of the continuous fastener element (10) is formed to have an average roughness Ra smaller than that of outer peripheral surfaces of the leg portions (12, 13). Accordingly, gloss and luster of the continuous fastener element (10) may be easily reduced or removed. Furthermore, since the head surface of the coupling head (11) has the average roughness Ra smaller than those of the leg portions (12, 13), when the slide fastener (20) is formed by using the continuous fastener element (10), the resistance between the coupling heads (11) of the left and right continuous fastener elements (10) may be made small and the left and right element rows may smoothly engage with each other or disengage from each other.
