Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glove using ultrafine fibers, and more particularly to a work glove suitable for a worker engaged in a process of assembling, inspecting, and cleaning a precision device or an optical device. The present invention relates to working gloves suitable for handling and cleaning gloves, lenses, jewelry, tableware, decorative tools, and the like.

[0002]

2. Description of the Related Art In general, workers involved in an assembly process or an inspection process of precision equipment or optical equipment, etc., are required to prevent the grease of fingers from adhering to the equipment when handling the equipment, and to wipe off any attached dirt. Wear work gloves.

[0003] As such work gloves, Japanese Utility Model Laid-Open No.
JP-A-64118 proposes a glove using a yarn in which a conductive carbon-containing synthetic polymer filament is mixed with a part of a knitting yarn. The purpose of this glove is to prevent the generation of static electricity due to the use of synthetic polymer filaments in the glove material.Even if antistatic properties are obtained, it is necessary to efficiently wipe off dirt such as oil film adhered to equipment. Was still not enough.

Japanese Utility Model Application Laid-Open No. 63-71860 proposes a glove in which at least the palm is made of a fabric made of ultra-fine multifilament yarn having a single yarn fineness of 0.2 denier or less. The use of this proposed glove has made it possible to easily wipe off even an oil film that could not be wiped off with conventional work gloves or wiping cloths.

[0005] However, wearing gloves makes indirect contact with equipment and the like via the fabric, and thus lacks a reliable handling property as in direct handling with bare hands. This has reduced workability in an assembly process, an inspection process, a cleaning process, and the like. In particular, when carrying out detailed work, the handling of a sensation far from the bare hand sensation has made workability extremely difficult.

In addition, since the worker must wear working gloves for a long time, stuffiness occurs in the glove, and the stuffiness causes discomfort and further reduces workability. .

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an excellent wiping property obtained from the use of ultra-fine fibers, while providing a handleability substantially similar to that of a bare hand and a comfort substantially free from stuffiness. Another object of the present invention is to provide a glove which reduces the amount of generated static electricity and is particularly suitable for work gloves.

[0008]

The glove according to the present invention comprises at least a part of the palm side made of a fabric comprising an ultrafine fiber filament having a fineness of 1 denier or less and a conductive filament, and the back side of the glove is provided. It is characterized by being made of a cloth made of conductive filaments and having air permeability of 350 cc / cm ² · sec or more, and wherein the palm side and the back side of the hand are three-dimensionally cut and sewn.

ec, more preferably 25 to 35 cc / cm ² · sec
And the air permeability of the fabric on the back of the hand is 350 to 45
0 cc / cm ² · sec, and the fabric on the back side of the hand is a fabric having a basis weight of 150 to 200 g / m ² composed of conductive filaments having a fineness of 1.5 to 2.5 denier, and the palm side and the back side of the hand Gloves, both of which are knitted. The glove of the present invention configured as described above is suitably used particularly as gloves for various operations.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The palm-side fabric constituting the glove of the present invention is a fabric comprising filaments of ultrafine fibers having a single yarn fineness of 1 denier or less and conductive filaments, and these are usually multifilaments. It has the form of.

The filaments made of ultrafine fibers used in the present invention can be obtained, for example, by dissolving or decomposing and removing the sea component of the sea-island composite fiber comprising two different synthetic polymers. By separating and separating each component of the split-type marine composite fiber composed of different synthetic polymers.

In the present invention, the synthetic polymer used for producing a multifilament comprising ultrafine fibers is not particularly limited, and any synthetic polymer can be used as long as it can be formed by a usual method. Even if there is, it can be applied. For example, polyester, polyamide, polyvinyl alcohol, polyolefin and the like can be exemplified, and among them, polyester is particularly preferably used.

In the present invention, the ultrafine fibers have a single yarn fineness of 1
The fibers are denier or less, preferably 0.5 denier or less, more preferably 0.2 denier or less, and if possible, ultrafine fibers such as 0.00001 denier.

As the conductive multifilament, for example, a filament made of a fiber-forming synthetic polymer containing a conductive substance such as carbon black or carbon fiber, particularly a core component of a core-sheath type composite fiber, is used. A filament made of a synthetic polymer containing a conductive material is used. As the synthetic polymer, a fiber-forming polymer such as polyamide, polyester, and polyacrylonitrile is preferably used.

Another example of the conductive multifilament is a fiber-forming synthetic polymer and a synthetic polymer which is miscible with the synthetic polymer but has no compatibility with the synthetic polymer. A filament having a fiber structure in which a number of synthetic polymers are dispersed and arranged in a streak form along the line can be used. For example, specifically, a block polyetheramide or a graft polyetheramide (modified polyamide) containing a polyalkylene ether segment is mixed and spun with a polyamide, polyester, or the like, and the modified polyamide is elongated in the polyamide or polyester in the fiber axis direction. Filaments mixed as dispersed particles can be used. Here, a filament in which a conductive substance such as carbon black is dispersed in the streak-form polymer is preferable. As the synthetic polymer, a fiber-forming polymer such as polyamide, polyester, and polyacrylonitrile is preferably used.

In the conductive multifilament used in the present invention, the conductive property means an electric non-resistance, preferably 1
0 to 10 ⁵ Ω · cm, more preferably 10 ² to 10 ⁴ Ω · cm
It is a value on the cm level. In addition, the thickness of the single fiber constituting the conductive multifilament can be 1 denier or less, which is the same as that of the ultrafine fiber, but is not particularly limited.
It may be the same thickness as the single fiber constituting the fabric of the back of the hand.

In the glove of the present invention, the fabric constituting the palm side is composed of the above-mentioned ultrafine fiber multifilaments and conductive multifilaments. The mixing ratio of the conductive multifilament yarns is preferably 0.
The level is from 0.05 to 10% by weight, more preferably from 0.1 to 3% by weight.

A woven or knitted fabric is usually used as the fabric constituting the palm side. In the case of the gloves of the present invention, a knitted fabric is preferable in terms of fit. As a means of mixing the microfilament multifilament and the conductive multifilament, there are a mixture of the microfilament multifilament and the conductive multifilament, a twisting of the microfilament multifilament yarn and the conductive multifilament yarn, or a mixing of the ultrafine fiber. Cross knitting of a multifilament yarn and a conductive multifilament yarn is exemplified. In the fabric on the palm side of the present invention, it is preferable that a multi-filament yarn of ultrafine fibers appears on the surface of the fabric and has a knitting structure that covers the surface.

On the other hand, the fabric on the back side of the hand of the present invention is constituted by using at least a conductive multifilament. The conductive multi-filament may have the same configuration as the conductive multi-filament used in the palm-side fabric. However, in view of moisture release from the glove, the filament has a single-filament fineness larger than that of the palm, such as 1. Preferably, 5 to 2.5 denier filaments are used.

The back side fabric of the present invention is desirably a knitted fabric from the viewpoint of improving the fit, and may be composed of only conductive multifilaments. May be mixed.

Next, the glove of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram for explaining a glove using a knitted fabric according to an embodiment of the present invention.

This glove 1 is composed of cut pieces of the knitted fabrics 2 and 3 in which the palm P and the back of the hand B are different from each other, and the thumb a is cut independently of these cut pieces. It is composed of knitted fabrics 2a, 3a whose sides are different from each other. Further, between the index finger b and the middle finger c,
Different cut pieces of the knitted fabric 3b are used between the middle finger c and the ring finger d and between the ring finger d and the little finger e. And
By these three-dimensional pieces being sewn three-dimensionally,
A glove 1 is configured.

In the glove 1 having the above-described structure, the knitted fabrics 2 and 2a on the palm P side and the knitted fabrics 3 and 2 on the back B side of the hand are used in order to achieve both the handleability of a bare hand and the comfort without stuffiness, which are the objects of the present invention. 3a and 3b are different from each other as follows.

Knitted fabrics 2 and 2 constituting the palm P side
a is knitted from an ultrafine fiber multifilament having a single yarn fineness of 1 denier or less and a conductive multifilament so that the air permeability is preferably 20 to 40 cc / cm ² · sec, and more preferably the basis weight is 100 to 130 g. /
It is organized into m ^2. On the other hand, the knitted pieces 3 and 3a of the cut pieces constituting the back B side of the hand preferably have a single yarn fineness of 1.
It is formed of a conductive multifilament having a density of 5 to 2.5 deniers, and is knitted so that the basis weight is preferably 150 to 200 g / m ² and the air permeability is preferably 350 cc / cm ² · sec or more.

Further, the knitted piece 3b of the cut piece provided between each finger for draping does not need the function of handling like the palm P side, so that the glove of the illustrated embodiment has the back side of the hand B side. The same knit as the knits 3, 3a is used. Of course, if necessary, the same knitted fabric as the palm side may be used.

In the glove 1 constructed as described above, since each cut piece is cut three-dimensionally, the glove 1 fits well to the hand when worn and follows the bending and stretching of the finger well, so that there is no resistance. . That is, in the case of conventional gloves, the palm side and the back side of the hand generally have a glove structure sewn in a plane from only two cut pieces, so if the fingers are bent and stretched, deformation of the gloves is impossible. Therefore, it is not possible to obtain a good fitting property as in the present invention by receiving the resistance force against it.

Further, the knitted fabrics 2 and 2a on the palm P side are formed from a multifilament of ultrafine fibers and a conductive multifilament so that the air permeability is 20 cc / cm ² · sec and the basis weight is 130 g / m ² or less. Thus, by combining this knitting structure with the above-described three-dimensional cutting and sewing structure having a good fit, the handleability which is substantially the same as that of the bare hand, which is the object of the present invention, is achieved.

In the present invention, the air permeability is JIS-L
The basis weight is measured according to the 1018-A method, and the basis weight is a value when the weight per 1 m ² of the fabric is expressed in g.

However, if the air permeability is too large or the fabric weight is too small in a knitted fabric or the like using ultrafine fibers as described above, it becomes difficult to secure the durability as a glove, and thus the air permeability is low. Is 40cc /
The upper limit can be up to cm ² · sec. Also,
The lower limit of the basis weight is preferably up to 100 g / m ² .

In addition, the use of ultra-fine fiber multifilaments and conductive multifilaments in the knitted fabric such as the palm side provides excellent wiping properties and antistatic properties. This wiping effect is obtained from the principle as shown in FIG.

That is, as shown in FIG. 2A, a multifilament F composed of a large number of ultrafine fibers f
An infinite number of gaps G are formed therein. A palm-side knitted fabric 2, 2a is formed from such a multifilament F, and a surface that is soiled by the knitted fabric 2, 2a is wiped off.
The wiped oil film and dirt D move from the surface of the knitted fabrics 2 and 2a to the gap G inside the multifilament F by the capillary action, and are trapped there. Accordingly, almost no oil film or dirt D remains on the surfaces of the knitted fabrics 2 and 2a, and it can be repeatedly wiped off.

On the other hand, the knitted fabric 3, 3a used on the back side of the hand
Is designed to promote anti-humidity as well as impart antistatic properties to prevent stuffiness, and to secure the necessary strength especially as work gloves. For this reason, a multifilament yarn having a single yarn fineness larger than the multifilament used on the palm side is preferably used.

As described above, the palm side and the back side are cut and sewn three-dimensionally from the highly elastic knitted fabric using the conductive multifilament, thereby reducing the resistance when bending and stretching the fingers in the gloved state. In addition to reducing the resistance, the knitted fabric to be used on the palm side is preferably made of an ultrafine fiber multifilament having a denier of 1 denier or less, preferably having an air permeability of 20 to 40 cc / m ^2.
By being knitted in SEC, the fitting property when handling the device is further improved, the handling property can be made as bare hand feeling, and the dust is prevented from being charged due to friction.

On the other hand, the knitted fabric 3 used on the back side of the hand is made of a multifilament yarn having a larger single-filament fineness than that of the palm side, with a basis weight of 150 to 200 g / m ² and a sufficiently large air permeability of 350 cc / cm ² · sec. With the above, it is possible to improve the moisture release from the glove, and to provide a comfortable wearing feeling without causing stuffiness in the glove even when worn for a long time.

Next, as a palm-side fabric, a tricot using 50 denier 630 filament polyester ultrafine fiber multifilament yarn and 25 denier polyester filament blended with carbon black was subjected to JIS L 1094-1988 C method (20).

c or more, and the palm side and the back side of the palm are cut and sewn three-dimensionally using these, so that while maintaining the excellent wiping properties obtained from the use of ultrafine fibers, the handleability of a bare hand feeling is substantially achieved. A glove suitable for work gloves, which has comfort that does not substantially cause stuffiness and has a reduced amount of generated static electricity, can be obtained.

When the fabric on both the palm side and the back side is made of a highly elastic knitted fabric, since the palm side and the back side are cut and sewn three-dimensionally, resistance to bending and stretching of the fingers is obtained. It has an excellent fit that reduces the feeling.

Further, the back side of the hand is made of an ultrafine multifilament yarn having a fineness of 1.5 to 2.5 denier, which is thicker than the palm side, at a basis weight of 150 to 200 g / m ² and an air permeability of 350 cc / cm ² ··· When the fabric is longer than sec, it has more excellent moisture release properties, and it is possible to obtain comfort that does not cause stuffiness in gloves even when worn for a long time.
