Abstract

A knitted slide fastener in which a stable knitted mode of a knitting structure is maintained, and a fastener element row is strongly attached to a warp knitting fastener tape. A fixing chain knitting yarn of the fastener element row in the fastener element attaching portion and knitting yarns configuring a ground structure are knitted with independent single structures, respectively. Needle loops which are connected to each other in a longitudinal direction of the fixing chain knitting yarn mounts each of element legs of the continuous fastener element row, sinker loops which are connected to each other in the longitudinal direction of the fixing chain knitting yarn go under a sinker loop of a second warp knitting yarn which configures the ground structure and cross each other.

First claim

The invention claimed is:

1. A knitted slide fastener, comprising:
a tape body of a fastener tape, and a fastener element attaching portion disposed along a side edge portion in a longitudinal direction of the tape body of the fastener tape, wherein the fastener tape is knitted and a continuous fastener element row is knitted on the fastener element attaching portion,
a plurality of knitting yarns configure a ground structure in the tape body and the fastener element attaching portion and each of at least two rows of wales in the fastener element attaching portion includes a fixing chain knitting yarn,
wherein the ground structure includes at least one second warp knitting yarn,
the fixing chain knitting yarn includes first, second, and third needle loops, which are consecutive needle loops of the fixing chain knitting yarn connected to each other in the longitudinal direction, wherein the second needle loop mounts element legs of the continuous fastener element row to the fastener element attaching portion, and each of two sinker loops extending toward the ground structure from the second needle loop goes under a respective sinker loop of the at least one second warp knitting yarn, wherein the respective sinker loops are adjacently arranged in the longitudinal direction.

2. The knitted slide fastener according to claim 1 , wherein the knitted slide fastener is a hidden slide fastener.

3. The knitted slide fastener according to claim 1 , wherein all wales of the tape body include a tricot knitting yarn and a weft in-laid yarn.

4. The knitted slide fastener according to claim 3 , wherein the fastener element attaching portion includes three or more wales, the second warp knitting yarn is knitted between a wale in the fastener element attaching portion which is most adjacent to the tape body and a wale in the tape body which is most adjacent to the fastener element attaching portion.

5. The knitted slide fastener according to claim 3 , wherein a needle loop of the second warp knitting yarn knitted in a wale of the tape body which is most adjacent to the fastener element attaching portion is knitted such that the needle loop of the second warp knitting yarn intertwines with a needle loop of the tricot knitting yarn of the tape body which configures the wale.

6. The knitted slide fastener according to claim 3 , wherein the second warp knitting yarn is knitted between all wales of the fastener element attaching portion.

7. The knitted slide fastener according to claim 3 , wherein the second warp knitting yarn is knitted in the ground structure between a first wale on an outermost side of the fastener element attaching portion and a second wale which is adjacent to the first wale.

8. The knitted slide fastener according to claim 3 , wherein the fixing chain knitting yarn is knitted in a wale of the tape body which is most adjacent to the fastener element attaching portion.
