Problems solved by technology

Because the corrugate tube is comparatively hard and heavy, the corrugate tube makes it less easy to perform a work of wiring the wire harness on the vehicle than the tape.
Thus the use of the tube has a problem that the number of processes increases.
Although a ta

first embodiment

[0031]a tape of the present invention for an electric wire is described below.

[0032]As shown in FIG. 1(A), a tape 1 of the present invention for electric wires is used to bind the electric wires by spirally winding it around a peripheral surface of a wire harness 2, consisting of a group W of electric wires, which is to be wired on a car by means of half-wrap winding of overlapping the half of the width of a portion of the tape 1 to be wound on a wound portion thereof or wide-pitch winding as shown in FIG. 1(B). The tape 1 can be also used for partial winding of partially winding it around the group of the electric wires in the longitudinal direction thereof. The tape 1 is used for portions where conventional general-purpose tapes for electric wires are used.

[0033]As shown in FIG. 2(A) which is an enlarged view of the tape 1, the tape 1 consists of a cloth tape formed by weaving warps 3 and wefts 4. As shown in FIG. 2 (C) which is a schematic perspective view, an adhesive agent 5 is...

second embodiment

[0047]The second embodiment is described below.

[0048]A tape of the second embodiment formed by weaving the warps and the wefts is irradiated with ionizing radiation to crosslink the general-purpose fiber strands consisting of the polyester fiber to allow the tape of the second embodiment to have a heat resistance higher than that of the tape 1 of the first embodiment and a melting temperature at 120° C.

[0049]The polyester fiber strand to be used as the general-purpose fiber strand is composed of a kneaded material containing polyester and 1 to 3 parts by weight of a crosslinking monomer consisting of triallyl isocyanurate or triallyl cyanurate added to 100 parts by mass of the polyester.

[0050]Yarns consisting of the general-purpose fiber strands and the high-function fiber strands similar to that of the first embodiment are woven by using the yarns as warps and wefts.

[0051]After the tape is formed by weaving the yarns, the tape is irradiated with the ionizing radiation having 100 kG...

Abstract

A tape which has enhanced heat resistance, flame retardancy, and wearing resistance and is suitable for use in bundling a group of electric wires which will be laid in a high-temperature environment. The tape is configured using the same yarns (10) each composed of high-function fiber filaments (11) and general-purpose fiber filaments (12), as a warp (3) and a weft (4). The high-function fiber filaments are superior to the general-purpose fiber filaments in heat resistance, flame retardancy, and wearing resistance. The high-function fiber filaments are of at least one kind selected from paraaramid fibers, polyarylate fibers, ultrahigh-molecular polyethylene fibers, glass fibers, and polyphenylene sulfide fibers. The general-purpose fiber filaments comprise at least one selected from polyesters, polyethylene, and polypropylene.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a tape for electric wires and more particularly to a binding tape which can be preferably used as a tape to be wound around a group of electric wires of a wire harness to be wired on a vehicle.[0003]2. Description of the Related Art[0004]The tape disclosed in Japanese Patent Applications Laid-Open No. 2003-272447 and the like is conventionally used to bind and protect a group of electric wires of a wire harness to be wired on a vehicle and prevent the wire harness from interfering with external interference materials. An adhesive agent is applied to one surface of the tape. The tape is spirally wound around the peripheral surface of a wire harness W / H to bind the group of the electric wires.[0005]Recently instead of the tape, a tube such as a corrugate tube is often used to bind and protect the group of the electric wires of the wire harness by inserting the group of the electric wires t...
