Abstract
A knitted fastener stringer has a chain stich yarn disposed on the innermost edge wale furthest from the tape body portion of an element attaching portion is the thickest of all the chain stich yarns used in a fastener tape. This enables a distance of a gap formed between left and right fastener tapes to be smaller when a slide fastener is formed by two knitted fastener stringers.
Claims10
A knitted fastener stringer, comprising
- a fastener tape including a warp knitting structure, and a plurality of fastener elements formed of monofilament made of synthetic resin, wherein the fastener tape includes a tape body portion, and an element attaching portion extending from one side edge portion of the tape body portion in a tape width direction and in which a part of the fastener elements is knitted, wherein the fastener tape includes a plurality of chain stitch yarns forming a plurality of needle loops in a chain shape along a wale direction,
- wherein the fastener tape includes a ground structure knitted in a single structure by the chain stitch yarns, a single satin stitch yarn that alternately forms needle loops on two wales disposed three rows distant from each other, and a weft insertion yarn inserted over a plurality of wales in a zigzag pattern, and
- the chain stitch yarn disposed on an innermost edge wale furthest from the tape body portion of the element attaching portion is the thickest of all the chain stitch yarns used in the ground structure of the fastener tape.
A manufacturing method for a knitted fastener stringer comprising
- a fastener tape including a warp knitting structure, and a plurality of fastener elements formed of monofilament made of synthetic resin, wherein the fastener tape includes a tape body portion, and an element attaching portion extending from one side edge portion of the tape body portion in a tape width direction and in which a part of the fastener elements is knitted, wherein the fastener tape includes a plurality of chain stitch yarns forming a plurality of needle loops in a chain shape along a wale direction, and
- wherein the method including
- knitting a ground structure of the fastener tape in a single structure by using the chain stitch yarns, a single satin stitch yarn that alternately forms needle loops on two wales disposed three rows distant from each other, and a weft insertion yarn inserted over a plurality of wales in a zigzag pattern, and
- using a thickest yarn of all the chain stitch yarns used in the ground structure of the fastener tape for the chain stitch yarn disposed on an innermost edge wale furthest from the tape body portion of the element attaching portion.
