Problems solved by technology

That is, in order to improve the conductivity, it is necessary to increase the blending ratio of the conductive yarn, which inevitably leads to an increase in the manufacturing cost.
[0004] In addition, in Patent Document 2, it is described that the conductivity with conductive threads in other directions is improved by covering the conductive thread around the non-conductive thread, but this also has the problem of processing cost of the core-spun yarn.

Embodiment 1

[0072] Two double-ply yarns of polyester fusion yarn (84 decitex-36 filaments) are used as the warp yarn forming the ground structure, and polyester false-twisted processed yarn (334 decitex-96 filaments) is used as the warp yarn Conductive thread and weft conductive thread use contains figure 2 Conductive filaments of surface-exposed fibers (84 decitex-9 filaments). Use the ground weave as plain weave (single dense pattern), weave through the dobby so that the warp conductive yarns are arranged according to the ratio of 1 of the 24 ground warp yarns (with a distance of 5 mm), skipping 2 outer warps and skipping 1 inner warp yarn. like figure 1 organization. In addition, the weft yarn conductive thread is inserted in the ratio of 1 out of 11 ground weft yarns (5mm spacing) in the weft double weave and arranged on the ground weft yarn (that is, it becomes a floating yarn), skipping 3 on the outside and skipping 1 on the inside. roots form as figure 1 organization. In this...

Embodiment 2

[0074] It carried out under the same conditions as Example 1, only changing the conductive thread. That is, as the conductive yarn, a parallel-twisted yarn (89 decitex-18 filament) of a polyester false-twisted processed yarn (33 decitex-12 filaments) and a surface-exposed conductive yarn (56 decitex-6 filaments) was used . The resulting fabric was sewn with a sewing machine, and the surface resistance value of the seamed portion was measured. Various data are described in Table 1.

Embodiment 3

[0076] Two double-ply yarns of polyester false-twisted processed yarn (84 decitex-36 filaments) are used for the warp yarn forming the ground structure, and polyester false-twisted processed yarn (334 decitex-96 filaments) is used for the weft yarn, A surface-exposed conductive yarn (84 dtex-9 filament) was used for the warp conductive yarn and the weft conductive yarn. The ground weave is used as plain weave (single dense pattern), and the warp conductive yarns are arranged according to the ratio of 1 out of 32 ground warp yarns (with a distance of 5 mm) through dobby weaving, forming 3 skipped outer threads and 1 skipped inner thread organization. In addition, the weft yarn conductive thread is inserted on the ground weft yarn in a ratio of 1 out of 15 ground weft yarns (5mm pitch) in a weft double weave, forming a weave that skips 6 outer and 2 inner weaves. In this way, the warp density is 202 / 2.54cm, and the weft density is 74 / 2.54cm. Refining, dyeing, and processing th...

Abstract

An optical fiber tape core wire can be branched using some tool. The optical fiber tape core wire comprises a plurality of optical fibers running in parallel, a collective coating which covers the plurality of optical fibers entirely, a recess formed in at least any one gap between the optical fibers and on the collective coating, and a plurality of slits arranged in series along each recess at a predetermined interval and permitting cleavage of the collective coating by inserting a tool through the collective coating and moving the tool along the recess. Length of the slit is set such that the bend of the optical fiber caused by spreading the slit with the tool does not exceed the allowable radius of curvature of the optical fiber.

Description

technical field [0001] The present invention relates to a fabric having excellent surface conductivity (conductivity) and antistatic properties, and clothes sewn with the fabric. More specifically, it relates to a woven fabric having surface conductivity across stitches in the entire region of the garment and having excellent electrostatic diffusibility, and a garment using the woven fabric. Background technique [0002] Historically, conductive clothing has been used to prevent electrostatic pickup in workplaces or clean rooms where electrostatically disturbed components, pharmaceuticals are handled. Conductive clothing has conductive threads woven into the garment in order to handle static electricity. For example, conductive threads are woven in stripes or grids at certain intervals, and corona discharge is used to neutralize static electricity, thereby preventing electrostatic dust collection. Patent Document 1 describes that conductive threads are often colored black ...
