Problems solved by technology
In the fastener belt described in Patent Document 1, since the main body portion of the belt has a net-like sparse structure, it is considered that the air permeability is relatively high, but since at least one of the warp yarns and the weft yarns is coated with a synthetic resin, and the warp yarns are There is a problem that the chain becomes too rigid due to welding at the intersection with the weft

Embodiment Construction
[0036] 1. Chain belt
[0037] In this invention, the fastener tape made of woven fabrics for slide fasteners including an element attaching part and a tape main body part is made object. The element attaching portion is a portion to which an element is attached, and the belt main body is a portion sewn to the main body of the article. In addition, the fastener belt may further include a selvage (Japanese: ear portion) for providing a selvage thread for preventing detachment at the side edge of the belt main body. It is also possible to provide the core wire part used when attaching the injection element or the metal element along the longitudinal direction of the fastener belt in the element attaching part.
[0038] In the fastener belt of the present invention, the belt body portion includes a mesh portion. The mesh portion has a skeleton formed of warp yarns consisting of three or more warp yarns and weft yarns consisting of three or more weft yarns, and has a mesh struc...

According to the present invention, it is possible to provide a fastener tape for a slide fastener. The fastener tape (100, 200, 300) for a slide fastener is a woven fabric product, and includes a fastener element mounting portion (101, 201, 301) and a tape main body portion (102, 202 , 302), wherein the belt main body (102, 202, 302) includes a mesh portion having a warp yarn formed by a group of three or more warp yarns and a weft yarn formed by a group of three or more weft yarns skeleton, and form a network structure with openings (107, 207, 307) between each group of warp yarns and weft yarns. The interlacing density of the warp and weft yarns on the inner side than the outermost warp and weft yarns is higher. The fastener tape of the present invention has a mesh structure capable of suppressing misalignment without welding the intersecting portions of the warp and weft.
Description
technical field [0001] The invention relates to a chain tape for a slide fastener. Furthermore, the invention relates to a slide fastener comprising the fastener tape. Background technique [0002] In addition to daily necessities such as clothing, luggage, footwear and department stores, zippers are mostly used as opening and closing tools in industrial products such as tents. Generally speaking, a zipper is mainly composed of a pair of long strips, many chain teeth sewn along one side edge of each belt as the engaging part of the zipper, and the opening or closing of the zipper is controlled by engaging and separating the chain teeth. The slider consists of three parts. [0003] As a tape for a slide fastener, a tape made of a woven fabric obtained by weaving a warp and a weft is often used. Figure 7 Indicates the basic structure of woven tapes for zippers. Should Figure 7 It is the first figure described in Japanese Utility Model Publication No. 5-42731 (Patent Docum...
