Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin sheet glove suitable for working in a place such as a clean room, handling food, and the like.

[0002]

2. Description of the Related Art For example, when working in a clean room or the like in which dust or dirt is not adhering, or when working with food, thin gloves that do not separate fine fibers and have a waterproof function are used. Often.

[0003] As this kind of thin sheet glove, there has been a conventional one in which the whole is formed of a thin film rubber or a soft synthetic resin material (for example, polyurethane resin). However,
Gloves formed entirely of rubber or a soft synthetic resin material have the drawback of poor durability (easy to tear) due to the thin film shape.

In recent years, as shown in FIGS. 1 and 2, a glove 1 is formed from glove cloths 2 and 2 made of a thin sheet in which an elastic film 5 is applied to one surface of a thin knit cloth 3. There is something. FIG. 2 shows the II of the glove 1 in FIG.
FIG. 2 is an enlarged cross-sectional view of FIG.

The knit fabric 3 of the glove fabrics 2 and 2 is knitted by loop-knitting a knitting yarn 14 in a horizontal direction as shown in, for example, an enlarged view in FIGS. It can be expanded and contracted. FIG. 3 is FIG.
FIG. 4 is an enlarged plan view of the portion III of FIG. 3 and 4, the knitting yarn 14 is considerably thicker in terms of balance. However, in the illustrated example, the knitting yarn 14 is indicated by a single line. As the knitting yarn 14, a relatively strong single yarn such as a nylon yarn is used. And the knitting yarn 14 itself knitting the knitted fabric 3 has almost no elasticity,
At present, the fabric is made elastic by loop knitting. On the other hand, a stretchable synthetic resin material such as a polyurethane resin is used for the film 5, and the synthetic resin material is applied in a thin film on the entire surface of one side of the knitted fabric 3. Note that the coating material is also filled in each mesh of the knit fabric 3.

[0006] Then, two glove cloths 2 and 2 are applied to each film 5.
The outer peripheral edges except for the hand insertion port are thermally bonded (thermally bonded portion 6) to form the glove 1 shown in FIG. Note that the glove 1 is used upside down, and at this time, the coating surface of the coating 5 appears on the front side of the glove. In the glove 1, the coating 5 on the front side performs a waterproof function when used, and the knit fabric 3 serves as a reinforcing material to ensure toughness. Also, since the surface of the knitted fabric 3 is on the inner side of the glove, the knitting yarn 14 is directly
No contact with treated articles.

In the glove 1 shown in FIG. 1, the glove cloth 2 has elasticity in order to make it easy to wear on a hand and to fit the hand in a worn state. The film 5 hardly expands and contracts because it is solidified by thermal bonding. That is, in the non-adhesive part fabric shown in FIG. 3, when the fabric is pulled in the left-right direction as shown by arrows F and F in FIG. 5, the knitting yarns 14 and 14 are loop-knitted and the film 5 has elasticity. So it can be extended relatively freely. Incidentally, at that time, since there is little elasticity in the knitting yarn 14 itself, A ₁ in FIG. 5 loop shape is horizontally deformed (Med height of each course of knitting yarn 14 from A ₀ in FIG. 3 well spacing with change is changed to B ₁ in FIG. 5 B ₀ in FIG. 3) is, the film 5 is also extended to follow along with it. On the other hand, in the cloth near the thermal bonding portion 6 shown in FIG.
As shown by arrows F and F in FIG. 2, the non-adhesive side (left side from the boundary line L) can be extended, but the thermal adhesive side does not extend.

[0008]

FIG. 1 to FIG.
In the glove 1 shown in FIG. 1, the cloth is stretched at the time of wearing (when inserting the hand).
Since the knitting yarn 14 of the knitted fabric 3 has almost no elasticity, the loop knitting shape is largely deformed as shown in FIG. 5 or FIG. 6 (the course height A ₁ decreases as the well interval B ₁ increases). ). At this time, in the non-adhesive portion (FIG. 5) of the outer peripheral edge of the glove away from the thermal adhesive portion 6 (FIG. 5), even if the loop knitting shape is deformed, there is room for the shape change. Near the boundary line L with the non-adhesion part (reference M
) Are less likely to be deformed. That is, as shown in FIG. 6, the knitting yarn 14 cannot be deformed on the side of the thermal bonding portion 6 when the fabric is subjected to the stretching action.
a, 14a... have a small deformation allowance, and therefore, a large tensile stress is concentrated on the knitting yarns 14a, 14a. In particular, when gloves are worn or when gloves are worn, as shown in FIG.
Because it is pulled at an angle of about 90 ° to the dough,
An unnatural force is applied to the cloth near the boundary M. When the tensile stress concentrates on the portion M in the vicinity of the boundary line, the coating 5 is easily broken by the knitting yarn 14a in the portion, and a minute hole (pinhole) is formed in the coating 5 near the knitting yarn 14a. It becomes easy to empty. Thus, if a pinhole is vacated in this portion, the waterproof function is impaired, and the hole gradually becomes larger due to the rubbing of the edge of the hole and the knitting yarn 14a, thereby shortening the durability (operable period). Problem occurs.

It is an object of the present invention to provide a thin sheet-like glove having a structure in which the above-mentioned pinhole is unlikely to occur in a glove formed of a thin sheet-like glove material in which an elastic film is formed on a knitted fabric. And

[0010]

The present invention has the following structure as means for solving the above-mentioned problems. That is, the thin sheet-like glove of the present invention uses a thin sheet-like glove fabric in which a film is formed on one or both sides of a knitted fabric knitted in a stretchable state with a stretchable synthetic resin material. The two glove cloths are formed by thermally bonding the outer peripheral edges of the two glove cloths except for the hand insertion opening.

The knitted fabric used in the glove fabric of the present application is formed by loop knitting of fine fibers in a flat knit state, for example. As the film, for example, a synthetic resin material having high elasticity such as a polyurethane resin can be used. The glove cloth may be one in which the coating is applied to only one side of the knitted cloth, or one in which the coating is applied to both sides.

In the thin sheet glove of the present invention,
As a knitting yarn for knitting the knitted fabric, a highly elastic woolly yarn is used for the yarn itself. Woolly yarns are called stretchable yarns.For example, long fibers such as polyester and nylon materials are processed in coil, loop, snare or a combination of these to give the yarn itself a large stretch function. It is a thing. Even in the case of glove cloth using this wooly thread, the heat-bonded portion at the outer peripheral edge of the glove has hardly any elasticity because the film (synthetic resin material) is cured by heating and solidifying.

By the way, in such a thin sheet-like glove using wooly yarn, there is considerable allowance for expansion and contraction of the cloth even in the vicinity of the thermal bonding portion on the outer peripheral edge of the glove. Therefore, even when an action such as stretching of the fabric near the heat-bonded portion acts when gloves are worn, the woolly yarn and the film are respectively stretched to follow the stretching force, and the fabric near the heat-bonded portion is subjected to a tensile stress. Is not concentrated.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION The embodiment of the present invention will be described below. The thin sheet-like glove according to the embodiment of the present invention is a knitting yarn for knitting a knit fabric 3 in the glove 1 shown in FIGS. As shown in FIG. 9, a wooly yarn 4 having high elasticity is used for the yarn itself. Note that FIG.
FIG. 9 is an enlarged plan view of a position corresponding to the IV portion, and FIG.
FIG.

The glove 1 of FIG. 1 applied in the embodiment of the present application
Uses two glove cloths 2 and 2 made of a thin sheet having a stretchable film 5 formed on one side of a thin knit cloth 3 as described in the section of the prior art. ,
The outer peripheral edges except for the hand insertion opening portion in FIG.

The knit fabric 3 used in the glove 1 of the embodiment of the present invention is knitted by loop-knitting a wooly thread 4 in a lateral direction as shown in FIGS. The wooly yarn 4 is called a stretch-processed yarn. For example, a long fiber of a polyester material or a nylon material is processed in a coil shape, a loop shape, a snare shape, or a combination thereof,
The yarn itself has a large stretching function. Although the wooly yarn 4 shown in FIGS. 8 and 9 is shown as a single line in a coil shape, it is actually manufactured in a combined state in which a number of fine long fibers are bundled into one. 8 and 9, the wooly thread 4 has a considerably large thickness in terms of balance. However, in order to make the description easy to understand, the wooly thread 4 is formed by a single coil wire. it's shown.

As shown in FIG. 8, the knit fabric 3 used in the embodiment of the present invention is knitted by loop-knitting a wooly yarn 4. Therefore, in this knitted fabric 3,
The elasticity of the wooly thread 4 itself and the elasticity of the loop knitting are further improved by the both functions.

The film 5 is made of a stretchable synthetic resin material such as a polyurethane resin, for example, and the synthetic resin material is applied to the entire surface of one side of the knitted fabric 3 in a thin film form. Note that the coating material is also filled in each mesh of the knit fabric 3. In another embodiment, the film 5 can be applied to both surfaces of the knitted fabric 3.

Then, the two glove cloths 2, 2 cut into a plane shape of the hand are joined with the surface on which the film 5 is formed,
The outer peripheral edges other than the hand insertion port are thermally bonded (thermally bonded portion 6) to form a glove 1 (the shape is the same as that of FIG. 1) of the present embodiment.

In the glove 1 of the embodiment of the present invention, the thermal bonding portion 6 on the outer peripheral edge of the glove hardly expands and contracts similarly to the conventional one (FIG. 4) because the film 5 is solidified by thermal bonding. On the other hand, the non-adhesive portion of the glove cloth 2 has a greater elasticity than the conventional one (FIGS. 3 and 4) because the knitting yarn 4 itself has elasticity.

The glove 1 of this embodiment is used upside down from the state shown in FIG. 1, and at this time, the coating surface of the coating 5 appears on the front side of the glove. Therefore, in this glove 1,
When used, the film 5 on the front side performs a waterproof function,
The knit fabric 3 serves as a reinforcing material to ensure toughness.
Further, since the surface of the knitted fabric 3 is on the inner side of the glove, the knitting yarn 4 does not directly contact the treated article.

When the glove 1 of the present embodiment is worn on a hand, the glove cloth 2 is stretched. At that time, a stretching force is also generated in the vicinity of the heat bonding portion 6. And
When a pulling force is applied to the vicinity of the heat bonding portion 6 in the left-right direction as shown by arrows F and F in FIG. 9, the knitting yarns (woolly yarns) 4 and 4 themselves also expand as the glove cloth 2 extends. . By the way, in the glove cloth 2 of this embodiment, since the knitting yarn 4 itself has elasticity, when a pulling force is applied in the left-right direction, the scale height (up and down) of each course (lateral direction) of the knit cloth 3 is increased. Direction) is not so small and well width (left-right direction)
Is deformed to be larger. At this time, the knitting yarn 4a in the vicinity of the boundary L between the heat-bonded portion 6 and the non-bonded portion is also extensible, so that the deformation margin of the knitting yarn 4a in the portion is increased, and the vicinity of the boundary L is reduced. The tensile stress unlike the conventional example (FIG. 6) is not concentrated on the knitting yarn 4a. Therefore, when the glove cloth 2 is extended, the stress generated on the coating 5 near the boundary line L is reduced, and the coating 5 in this portion can follow and extend the tensile force with a margin. When the film 5 extends with a margin as described above, the film 5 is not broken (a pinhole does not occur). When the glove cloth 2 is extended, the cloth far away from the thermal bonding portion 6 is extended with a margin, so that the film 5 is not likely to be broken. Further, since the glove cloth 2 has a larger amount of expansion and contraction than the conventional (FIGS. 3 and 4) glove cloth, the glove cloth can be sufficiently extended when the glove 1 is worn on a hand. Work becomes easy.

Conventional glove cloth (using filament cloth)
The results of an extension test performed on the glove fabric (using wooly fabric) of the present embodiment are shown below. The material used was a fabric obtained by loop-knitting a filament yarn (conventional example) and a wooly yarn (embodiment of the present invention) under the same conditions, and forming a film under the same conditions. As a result of the test, the elongation in the course direction was up to 225% in the material of the conventional product, but the elongation in the course direction was 380% in the material of the present application.

[0024]

As described above, in the thin sheet-like glove of the present invention, since the wooly yarn 4 having high elasticity is used as the knitting yarn of the knitted fabric 3, the elasticity is larger than that of the conventional gloved fabric. In addition, since the woolly yarn 4 can be stretched even near the boundary line L with the heat bonding portion 6, the effect that the film 5 is hardly torn when the glove cloth 2 is stretched (pinholes are hardly generated) is obtained. Therefore, the thin sheet glove of the present invention has the effects of improving the durability against the stretching action and extending the usable period. Glove cloth 2
When the elasticity of the glove is large, there is also an effect that it can be performed smoothly when the glove is worn (when the hand is inserted into the glove).
