Problems solved by technology

However, the open type requires cylindrical molding with a mold or half-lap winding with tape, and there is a risk that the wire harness will be exposed from the slit opening after coating.

Embodiment 1

[0076] A section of heated false-twisted textured yarn of polyester of 330dtex and 167dtex is used as the warp yarn. As the weft, three 90 dtex polyester filaments with a shrinkage rate of 15.3% were combined (paralleled) and polyester monofilaments with a shrinkage rate of 2.0% and a single fiber diameter of 250 μm were used. The weft of these three polyester filaments is called yarn B (hereinafter referred to as "weft B"), and the weft of polyester monofilament is yarn A (weft A). Using these warp yarns and weft yarns, a double-layer fabric having a warp yarn density of 154 yarns / 2.54 cm, a weft yarn weaving density of 22 yarns / cm, and a fabric width of 25.5 mm was woven.

[0077] figure 1 , 2 The configuration of the woven double layer fabric is shown. A and B in each figure indicate weft yarns, and x, y, and z indicate warp yarns. A is weft A, B is weft B, x and y are 330dtex polyester heated textured yarn, z is 167dtex polyester heated textured yarn. In addition, A' ...

Embodiment 2

[0081] As the weft yarn B, three polyester filaments of 90 dtex with a shrinkage rate of 20.5% were combined (paralleled), and as the weft yarn A, polyester monofilaments with a shrinkage rate of 6.7% and a single fiber diameter of 250 μm were used. Except for this, a two-layer fabric was woven in the same manner as in Example 1.

Embodiment 3

[0083] As the weft yarn B, three polyester filaments of 90 dtex with a shrinkage rate of 49.3% were combined, and as the weft yarn A, a polyester monofilament with a shrinkage rate of 2.0% and a fiber diameter of 250 μm was used. In addition, A two-layer fabric was woven in the same manner as in Example 1.

Abstract

The present invention is a two- or more ply flat woven textile in which a texture A comprising a yarn A and a texture B comprising a yarn B are interwoven, wherein the yarn A and the yarn B are both a warp yarn or both a weft yarn, and shrinkage percentage of the yarn A (SA (%)) and shrinkage percentage of the yarn B (SB (%)) satisfies a specific range. The woven textile of the present invention, when heat is applied, is spontaneously formed into a tube with a sufficient overlap in the circumferential direction. This tube provides easy insertion of lead wires and is able to protect the lead wires reliably without exposing the inserted lead wires.

Description

technical field [0001] The present invention relates to a fabric and a covering material for electrical wiring using the same. Background technique [0002] Conventionally, when a flat fabric is processed into a tubular shape, a method of placing the fabric on a cylindrical mold and forming a tubular shape by thermoforming is generally used. This processing method requires technology in thermoforming in order to form the fabric into a tubular shape, and the processing cost is high, so it is difficult to provide it at a low price. [0003] In addition, as the number of electric wires used increases with the increase in electrical products, the usage-amount of the covering material for electrical wiring tends to increase. There are two types of covering materials for electrical wiring, open type with slits in the longitudinal direction, and closed type with a completely cylindrical shape. In the case of the closed type, it is necessary to work from the opening at one end in ...
