DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to gloves, and more particularly to gloves particularly useful for motorbikes and snowmobile drivers and skiers.

[0002]

2. Description of the Related Art Japanese Utility Model Application Laid-Open No. 60-122325 and Japanese Utility Model Application Laid-Open No. 17517/1995 disclose a glove made of a laminated material including an outer skin, a mesothelium and an endothelium, in which a nichrome wire corresponds to a fingertip of the messeal. A glove fixed to an area with an adhesive or the like is disclosed. Both ends of the nichrome wire are connected to the anode and cathode leads, respectively, so that the glove is heated by connecting to an external power source, and the inside of the glove is kept warm.

[0003] However, the nichrome wire has poor resistance to flex wear and is inherently liable to break. In particular, in the case of gloves in which the finger flexes sharply, breakage of the nichrome wire is inevitable. If the nichrome wire breaks, it is necessary to disassemble the glove to restore the glove to its original heatable state, which is complicated. Further, the nichrome wire is hard, so that the feel of the glove itself is hard, and there is a sense of discomfort when worn. In particular, when the driver blinks the turn signal, a delicate steering wheel grip operation with a fingertip is hindered.

[0004]

One example of the insulating means is to laminate an insulating film on the front side and the back side of the entire middle coat 2. Another example of the insulating means is to coat the heat-generating yarn to be twisted with a vinyl chloride resin, a silicone resin, or the like so as to be seen in the electric wire coating.

Power supply connectors are attached to both ends of the heat-generating yarn 4. Connectors for power connection 5, 5
′ Is a female type and connectors 6, 6 ′ connected to these
The male type makes it easier to insulate and prevent rainwater from entering when running in rain. The connectors 5, 5 ', 6, and 6' are covered with a cover 12 in order to prevent rainwater from entering as much as possible, and a fastener such as Velcro (pressure-sensitive fastener, registered trademark) (for example, a cover 12 as shown in FIG. 1).
It is preferable to fasten with a male or female fastener 13 attached to the outer shell 1 and a female or male fastener 12) attached to the outer skin 1.

The connectors 6, 6 'are connected to a power source 11, such as a battery, via an anode lead 7 or a cathode lead 8, a fuse 9, and a switch 10. As the power supply 11, an external power supply such as a motorcycle battery can be used, or a storage battery may be directly incorporated in gloves.

Here, the exothermic yarn used in the present invention will be described. Exothermic yarns Article consists discontinuous conductive metal lines and a non-conductive fibers mixed comprising assembled into filamentous flexible filamentous heating element. The conductive metal wire constituting the heat-generating yarn used in the present invention is a conductive metal fiber having good spreadability such as iron, copper, and aluminum, and has a fiber length of 1.
Those having a range of 00 to 800 mm are used. A preferred metal wire has a diameter of 4 to 30 μm and a fiber length of 100 to 8
Stainless steel fibers in the range of 00 mm. As the non-conductive fibers, artificial or natural fibers having a fiber length in the range of 100 to 800 mm are used.

[0011] The discontinuous conductive metal wire is mixed with the non-conductive fiber and aggregated into a thread form (that is, blended) to form a heat-generating yarn. By blending with the non-conductive fiber, the line resistance of the exothermic yarn can be adjusted to a desired value.
The mixing amount of the conductive metal wire and the non-conductive fiber is 20 to 60% by weight for the former and 80 to 4 for the latter based on the weight of the heat generating yarn.
It is preferably 0% by weight.

A mixture comprising a conductive metal wire and a non-conductive fiber
The spun yarn is twisted with a lower twist coefficient of 5,500 to 13,500
You. In the cross section of the blended yarn, 20 or more discontinuous fibers made of stainless steel having the above-described diameter and fiber length are included, and the lower twist coefficient is 5,500 to 13,
Exothermic yarns formed from blended yarns in the range of 500 are particularly preferred. A plurality of such blended yarns are plied, and a twist is given to this to form a cord yarn, and the twist has a twist in a direction opposite to the twist direction of the twist, and a twist factor and a twist. The coefficient ratio is in the range of 0.5 to 1.50, the line resistance of the cord yarn is in the range of 0.05 to 10 Ω / cm, and the resistance value variation coefficient C
A cord yarn whose V% satisfies CV ≦ 10 is most suitable as a heat-generating yarn. Here, the twist coefficient (K) is K = Tm (1
The number of twists per m) × (total denier of yarn) ^1/2 .

[0013] The reasons for adding a priming and a plying to the above blended yarn are as follows. In the above blended yarns before twisting, while the heating element made of conductive discontinuous fibers has a flexible, depending on the operating conditions, such as using a flexible heating element, the form stability loss The relative positions of the fibers constituting the heating element may not be constant. In addition, since such a blended yarn generates heat using contact resistance, it may be difficult to obtain a constant heating temperature. The above-mentioned priming removes such difficulties of the untwisted blended yarn, and functions to increase the uniformity of the contact resistance by keeping the relative positions of the short fibers constant. In addition, when twisting is performed, the balance between the twists of the lower twist and the upper twist is particularly important. That is, in general, twist setting is performed for thermoplastic fibers such as synthetic fibers to prevent the generation of twisting torque. Therefore, the balance of twist is important.

Synthetic fibers, regenerated fibers, and natural fibers are used as non-conductive fibers blended with discontinuous fibers made of conductive metal wires. Among them, wholly aromatic polyamide fibers (aramid fibers) are used. Since the heat resistance is high, the discontinuous fibers of the conductive metal wire generate heat and do not deteriorate or ignite even if the temperature rises, which is preferable. In addition, preferable examples of the heat-resistant fiber include a fiber made of a heat-resistant polymer such as a polybenzimidazole fiber, a polyimide fiber, and a polyetheretherketone fiber.

In order to form a blended yarn from a discontinuous conductive metal wire and a non-conductive fiber, the conductive metal wire and the non-conductive fiber are aligned and supplied to a pulling device to form a mixed yarn. A method in which both conductive fibers are discontinuous fibers having a length of 100 to 800 mm is preferably employed. Also, the thickness of the exothermic yarn is
5,000 de-25,000 in consideration of sewing to mesothelium
About 0de is appropriate.

The amount of the exothermic thread to be sewn to the glove's inner skin should be such that a suitable calorific value is obtained. That is,
In a cold region (0 ° C. atmosphere), it is preferable to heat the glove to about 10 to 35 ° C. in 5 to 20 minutes. For this purpose, about 3 to 15 W is required for heat generation (W: watt). Now, the surface area of the inner skin 2 to which the exothermic yarn 4 is sewn is 100 cm ² , and the required wattage is 10 W / 100.
and cm ^2. On the other hand, the wire resistance of the heat-generating yarn 4 is 0.1 Ω.
/ Cm, and the voltage of the power supply is 12 V, the length of the exothermic thread required for sewing can be obtained as follows.

Since W = I × V and V = I × Ω, W
(= 10) = I × V (= 12), I is 0.83
(Amps). Next, when the value of I is substituted into the equation of V = I × Ω (12 = 0.83 × Ω), the required resistance value is 14.5Ω. Therefore, in order to obtain this resistance value of 14.5 Ω with the above-mentioned exothermic yarn having a line resistance value of 0.1 Ω / cm, a length of 145 cm is required. Therefore,
The heat-generating thread 4 having a length of 145 cm may be stitched to the inner skin 2 as shown in FIG.
