## Abstract

A tape for a slide fastener includes warps and wefts. A yarn count of warps among yarns forming the fastener tape is set to 22-28 dTex. A weave density of the warps is set to 205-231 yarns/inch. A yarn count of wefts among the yarns forming the fastener tape is set to 81-87 dTex. A weave density of the wefts is set to 42-48 yarns/inch. The weft is a multifilament formed by bundling 33-39 monofilaments. According to one embodiment, the yarn count of the warps is set to 25 dTex, the weave density of the warps is set to 210-226 yarns/inch, the yarn count of the weft is set to 84 dTex, the weave density of the wefts is set to 43-46 yarns/inch, and the weft is a multifilament formed by bundling 36 monofilaments.
