A plurality of warp threads includes total N adjacent tightening threads each repeats crossing over N second legs at a side of the first tape-surface and crossing over the weft thread at a side of the second tape-surface so as to tighten the coil-shaped element to the weft thread. Said N indicates a natural number equal to or greater than 2. Each tightening thread includes an exposed portion that crosses over the weft thread and is exposed at a side of the second tape-surface. As the N adjacent tightening threads extend, the respective exposed portions of the tightening threads appear at a side of the second tape-surface one-by-one alternately or one-by-one sequentially.

Fastener stringer and slide fastener

An incorporated slide fastener that is incorporated simultaneously with the weaving of the fastener tape for a zigzag-type continuous element. The weft yarn of the fastener tape is woven with one thread traversing and doubling back in the tape width direction, forming a set of two threads. Fastener elements have: engaging heads; first and second leg portions that each extend in the width direction of the tape; first connecting portions that connect first legs that are adjacent in the longitudinal direction of the tape; and second connecting parts that connect second legs that are adjacent in the longitudinal direction of the tape. Of the two yarns configuring the weft yarn, one yarn is woven diagonally straddling the first surface of a first leg and the second surface of a second leg of adjacent fastener elements.

Incorporated slide fastener

A woven slide fastener in which displacements of element anchoring warps in a width direction of a fastener tape does not occur, flexibility of the fastener and smooth operation of a slider are ensured, and anchoring of a fastener element row is stable. Two anchoring warps disposed closest to coupling heads out of a plurality of element anchoring warps running over upper leg portions of the fastener element row run with and parallel to a double-picked foundation weft running under lower leg portions of adjacent elements and are woven in a width direction of a fastener tape body portion while interlacing with other element anchoring warps and foundation warps. Therefore, the element row can be anchored firmly, and the two anchoring warps do not fall off the elements, and other element anchoring warps also do not fall off of the elements.
