Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elastic glove having a lining.

[0002]

BACKGROUND OF THE INVENTION Rubber or resin gloves are so-called support type gloves having knitted gloves or sewn gloves as a lining, and so-called non-support type gloves having no lining. There are some.
Of these, the support-type gloves have higher strength than the non-support-type gloves, and are therefore used as gloves for various heavy and light work. A seamless knitted glove is preferably used from the viewpoint of forming a film having a uniform thickness and a good appearance as the lining of the support type glove. Furthermore, from the viewpoint of sweat absorption and wearability, cotton yarn is preferably used as a material for knitted gloves.

However, since the elastic film is provided on the outer surface of the knitted glove, the modulus becomes higher than that of the knitted glove alone. Therefore, even if the sweat absorbability and the wearability are originally excellent, It is inevitable that the support gloves as a whole will deteriorate in sweat absorption and wearability, as well as fit and workability. In addition, an ordinary support-type glove has a lining over the entire inner surface of the glove (that is, the surface that comes into contact with the palm), and since no elastic film is formed on the inner surface, the detachability is good. However, my hands are slippery inside the gloves. Therefore, there is a problem that inconvenience occurs when working with gloves on.

Therefore, an object of the present invention is that the slipperiness of the hand inside the glove is appropriately adjusted, and the detachability of the glove is good, while the hand is hard to slip when the glove is worn. It is an object of the present invention to provide a support-type glove that has good gripping property, excellent fit, workability, and heat insulating property and can prevent stuffiness and dripping of sleeves.

[0005]

MEANS FOR SOLVING THE PROBLEMS AND EFFECTS OF THE INVENTION The support type glove of the present invention for solving the above problems is knitted using 5 to 80 count yarn in terms of one cotton count single yarn. The knitted glove having the number of stitches of 10 to 2000 per 1 square inch, and the elastic film formed on the outer surface of the knitted glove are provided on the inner surface of the knitted glove. The total area of the exposed parts is 10 to 90% of the total area of the region where the film is provided.

According to the support type glove of the present invention, since the support type glove is provided with the knitted glove as the lining, the elongation is limited as compared with the glove having only the elastic film, and therefore, the excellent detachability and fit feeling can be obtained. , And flexibility can be obtained. Furthermore, by providing a knitted glove in which the count and the number of stitches of the thread used are appropriately adjusted, it becomes difficult for stuffiness to occur inside the glove, and the glove also has excellent heat insulating properties. Moreover, since the sleeve portion is tensioned by providing the knitted glove, there is no problem that the sleeve portion hangs or shifts when worn.

Further, since the elastic film is exposed on a part of the inner surface of the knitted glove and the proportion of the exposed film is adjusted appropriately, the elasticity of the knitted glove as the lining and the surface is improved. While removing the glove from the body film, the glove may come into contact with the knitted glove when the glove is put on and taken off, and the glove may come into contact with the glove when the glove is worn. It can be appropriately adjusted so as to be in close contact and less likely to slip.

Further, as will be described later, the support type glove of the present invention has a structure in which the glove type is covered with a knitted glove and then the hand type is dipped in rubber latex or resin emulsion. Also, it is manufactured through a process of forming an elastic film on the surface of the knitted glove and removing the glove from the hand mold without inverting. In this way, the elastic film of the support-type glove is unlikely to be distorted because it is not inverted when the mold is released. Further, since the elastic film is less likely to be distorted, the film is less likely to be cracked or damaged, and the aging resistance and ozone resistance are better than those of a non-support type glove having no lining.

In the support type glove of the present invention, when the elastic film is provided on the entire outer surface of the knitted glove, it is possible to prevent water from penetrating from the outside to the inside of the glove. . On the other hand, in the support type glove of the present invention, when the elastic film is not provided at a portion corresponding to the upper part of the knitted glove, it is possible to prevent stuffiness or the like caused by sweat or the like.

In the support type glove of the present invention, the elastic body is preferably natural rubber or deproteinized natural rubber.
In this case, the modulus of the elastic film can be suppressed to a low level, and it is possible to obtain a support-type glove that is further excellent in fit, flexibility and detachability.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Next, the support type glove according to the present invention will be described in detail. One embodiment of the support type glove of the present invention includes, for example, the one shown in FIG. 1 (a). In FIG. 1 (a), the elastic film 11 forming the outer surface of the support type glove 10 is removed in the area surrounded by the dotted line,
It shows a state in which the knitted gloves 12 forming the inner surface of the support type glove 10 have appeared. The outer surface 12a of the knitted glove 12 is provided with an elastic film 11 at a part thereof or over the entire surface thereof and has a cross-sectional structure as shown in FIG. 1 (b). The inner surface 12b of the knitted glove 12 has a reference numeral 1
As indicated by the reference numeral 1a, the elastic film 11 is exposed at a part thereof.

[Knitted Gloves] The yarn forming the knitted gloves is not particularly limited, and various conventionally known yarns can be used. Specifically, threads made of natural fibers such as cotton, wool and hemp, nylon, polyester, rayon, acrylic,
A yarn made of synthetic fiber such as polyurethane, or a yarn made by mixing these fibers can be used.

Threads made of high-strength fibers such as aramid fibers can also be used as threads for knitted gloves. In this case, for example, even when working with a blade, the fingers can be sufficiently protected. It is also possible to use a yarn made of a fiber having a modified cross section, for example, having a convex portion or a concave portion on the outer peripheral portion in the cross section. Depending on the fiber shape used, it is possible to obtain the effect of further improving the effect of preventing stuffiness due to sweat or the like.

In the support type glove of the present invention, the knitted glove uses 5 to 80 count yarn in terms of one cotton count single yarn, and the number of stitches is 10 to 2000 per 1 square inch. The set one is used. If the yarn count is less than the above range (thick yarn) or the number of stitches exceeds the above range, the knitted gloves will have too fine stitches and the elasticity will decrease, resulting in poor fit and workability. descend.

On the other hand, when the yarn count exceeds the above range (the yarn is thin) or the number of stitches falls below the above range, the gloves are less tense and the elasticity is too large, so that the detachability is deteriorated. However, the sleeve is likely to sag. In addition, sweat absorption and heat insulation also decrease. Further, in this case, there is a problem that it becomes difficult to attach the knitted glove to the hand mold when forming the film (workability at the time of forming the film decreases). As described above, the lower limit of the yarn count for forming the knitted glove (corresponding to one cotton count single yarn) is 5th count, and preferably 10th count. On the other hand, the upper limit of the count is 80, as described above, preferably 50, and more preferably 20.
The number is, more preferably 15th.

The lower limit of the number of stitches (number per square inch) is 10, as described above, preferably 25, more preferably 50. On the other hand, the upper limit of the number of stitches is 2000 as described above, preferably 1500.
It is more preferably 1000, still more preferably 300, and especially 200. The above range is based on the premise that one yarn is knitted. In the present invention, the yarn used for the knitted glove is not limited to the one-ply yarn, but may be two to several yarns. When twin yarns are used or the number of picked yarns is different, the above range may be determined by the converted value.

The knitted glove is usually composed of one layer, but in the case of increasing the strength of the glove or manufacturing a glove for working with a knife, a plurality of layers may be laminated. Good. The knitting structure of the knitted glove may be any conventionally known knitted fabric such as plain knitting or rubber knitting, and the selection thereof may be appropriately made according to the properties required for the glove. The number of stitches may be partially changed.

[Elastic Body Coating] In the present invention, the elastic body material for forming the coating provided on the outer surface of the knitted glove includes, for example, natural rubber (NR) and deproteinized natural rubber (D).
PNR), acrylonitrile-butadiene rubber (NB
R), chloroprene rubber (CR), rubber such as styrene-butadiene rubber (SBR), resins such as acrylic resin and vinyl chloride resin, or blends or composites thereof.

Among the elastic materials exemplified above, natural rubber and deproteinized natural rubber are more preferable because they have a low modulus and can form a film having excellent flexibility. Here, the deproteinized natural rubber means a natural rubber obtained by removing proteins contained in the natural rubber latex.
The method for deproteinizing natural rubber (latex) is not particularly limited, and various conventionally known methods can be adopted, but natural rubber latex is aged by adding a protease and a surfactant. The method of separating and purifying the rubber component by centrifugation is preferable because the deproteinization effect is high.

The thickness of the elastic film is the thickness of the entire glove,
It is set according to the flexibility, strength, heat insulation, etc. required for gloves. Therefore, the thickness of the coating is preferably 0.05 to 0.7 mm, more preferably 0.3 to 0.5 mm, although not particularly limited.

In the present invention, the proportion of the elastic film 11 exposed on the inner surface 12b of the knitted glove, that is, the exposed portion 11a of the elastic film occupying the entire outer surface 12a of the knitted glove.
(Hereinafter, referred to as "film appearance rate") is 10 to 9
It is set in the range of 0%. When the film appearance rate is less than the above range, the flexibility is lowered and the fit and workability are lowered. Further, since the exposed area of the knitted glove is increased on the inner surface of the glove, the hand becomes slippery in the glove and the grip force is reduced. On the contrary, if the film appearance rate exceeds the above range, the fiber portion on the inner surface of the glove becomes too small,
The slipperiness when putting on and taking off may become poor, and the inside of the gloves may become damp when worn. The lower limit of the film appearance rate is 10% as described above, preferably 15%, more preferably 30%.
On the other hand, the upper limit of the film appearance rate is 90% as described above, preferably 85%, more preferably 70%.

The appearance rate of the film may be measured, for example, by analyzing the inner surface of the support type glove with an image processing apparatus or visually recognizing it.
In the former case, the color difference between the rubber or resin elastic body portion and the fiber (knitted glove) portion on the inner surface of the glove can be binarized, and the areas of both can be automatically measured. In the latter case, for example, the elastic portion and the fiber portion may be copied on a piece of graph paper and the area ratio may be measured. The support type glove of the present invention may be subjected to a non-slip process such as providing unevenness on the surface of the elastic film.

[Manufacturing Method of Support-Type Gloves] (Production of Knitted Gloves) Knitted gloves can be manufactured, for example, by using a knitting machine such as a knitting machine exclusively for gloves. The yarn count and the number of stitches to be used may be appropriately adjusted depending on the desired film appearance rate and the physical properties required for the knitted glove, such as strength and flexibility.

(Formation of Elastic Film) The elastic film can be formed, for example, by a dipping method using the above-mentioned rubber latex or resin emulsion. That is, the elastic film is prepared by blending a latex containing the above-mentioned rubber with a vulcanizing agent, a vulcanization accelerator, a filler and the like according to a conventional method,
Alternatively, it can be formed by blending an emulsion containing the above-exemplified resin with a cross-linking agent and the like according to a conventional method and then immersing a glove mold covered with a knitted glove in the blended latex or emulsion thus obtained. After the dipping in the latex or emulsion, the film formed on the surface of the knitted glove may be dried and vulcanized (crosslinked) by a conventional method.

In addition to the above-mentioned dipping method, the elastic film is formed by, for example, a so-called shower method in which (a) a rubber latex or a resin emulsion is sprayed on a knitted glove,
(b) Viscosity pickup method in which a mold with knitted gloves is placed in a thickened rubber latex or resin emulsion and dried while rotating to prevent dripping, (c) Rubber latex or resin emulsion with heat sensitivity It can also be formed by a so-called heat-sensitive method of immersing, and (d) an ordinary coagulating solution method in which a coagulating solution is adhered to the surface of a knitted glove and then a mold is immersed in a compounded latex or a resin emulsion. The formation of the film by these methods may be carried out according to a conventional method.

Compounding agents added to the rubber latex include vulcanizing agents, vulcanization accelerators, vulcanization accelerating aids (activators),
Antiaging agents, fillers, dispersants and the like can be mentioned. Examples of the vulcanizing agent include sulfur and organic sulfur-containing compounds. The compounding amount thereof is preferably about 0.5 to 3 parts by weight based on 100 parts by weight of the rubber content of the rubber latex.
Examples of the vulcanization accelerator include PX (zinc N-ethyl-N-phenyldithiocarbamate), PZ (zinc dimethyldithiocarbamate), EZ (zinc diethyldithiocarbamate), BZ (zinc dibutyldithiocarbamate), MZ (2- Mercaptobenzothiazole zinc salt), TT (tetramethylthiuram disulfide), and the like. These may be used alone or in combination of two or more. The compounding amount thereof is preferably about 0.5 to 3 parts by weight based on 100 parts by weight of the rubber content of the rubber latex. Examples of the vulcanization accelerating aid include zinc white. The compounding amount thereof is preferably 0.5 to 3 parts by weight with respect to 100 parts by weight of the rubber content of the rubber latex.

As the antiaging agent, generally, non-polluting phenols are preferably used, but amines may be used. The compounding amount of the antioxidant is preferably about 0.5 to 3 parts by weight with respect to 100 parts by weight of the rubber content of the rubber latex. Examples of the filler include kaolin clay, hard clay, calcium carbonate and the like. The compounding amount thereof is preferably 10 parts by weight or less based on 100 parts by weight of the rubber content of the rubber latex. Further, a dispersant may be added in order to improve the dispersion of each of the above additives in the rubber latex. Examples of such a dispersant include various anionic surfactants. The compounding amount of the dispersant is 0.3 to the weight of the component to be dispersed.
It is preferably about 1.0% by weight.

The vulcanization conditions of the film obtained by using the rubber latex are not particularly limited, and according to a conventional method,
Usually, it is preferable to carry out at 100 to 120 ° C. for about 30 to 90 minutes. The latex may be prevulcanized. Pre-vulcanization is usually performed at 30 to 50 ° C. according to a conventional method.
It is preferably carried out for about 15 to 30 hours. The resin emulsion preferably contains a cross-linking agent in order to make the resin sufficiently cross-linkable and to improve the strength of the glove. When the resin emulsion has a self-crosslinking property, the film can be formed without adding a crosslinking agent, but the addition of the crosslinking agent can further improve the strength of the glove.

Examples of the cross-linking agent include various conventionally known cross-linking agents used for polymer processing, such as zinc white, melamine resin, and epoxy resin. The compounding amount of the cross-linking agent is not particularly limited, but is 1 to 10 parts by weight, particularly 1 to 10 parts by weight with respect to 100 parts by weight of the resin solid content of the resin emulsion.
It is preferably 5 parts by weight. The mold (hand mold) used to form the elastic film may be, for example, a pottery or ceramic one. When preheating the hand mold, the preheating temperature may be appropriately determined depending on the film forming method, the heat-sensitizing agent used, and the like.

(Method of adjusting film appearance rate) The ratio of the film appearing on the inner surface of the knitted glove (film appearance rate) depends on the viscosity of the rubber latex or resin emulsion, the rubber content or resin content of the latex or emulsion. Various parameters such as concentration, temperature of rubber latex or resin emulsion, immersion time of hand mold in rubber latex or resin emulsion, concentration of coagulating liquid, yarn count used for knitting gloves, number of stitches of knitting gloves are changed. By doing so, it can be adjusted appropriately.

Generally, by increasing the viscosity of the rubber latex or resin emulsion, the film appearance rate can be suppressed to a low level, and by increasing the hand dipping time in the rubber latex or resin emulsion, the film appearance rate can be increased. Can be higher.
