Description

  The present invention relates to an inner glove worn under industrial rubber gloves or the like.

  When performing various operations, for example, when working in a clean room or handling food, rubber gloves are worn. Rubber gloves are gradually becoming thinner so that they are closely attached to the hand to perform fine work, and are approaching the touch when directly handled by hand. However, since rubber gloves are not breathable, inner gloves are used to reduce stuffiness during wearing and to improve the feeling of wearing. In addition, rubber gloves are poorly slidable with the skin and cannot be handled smoothly during attachment / detachment, and are often torn.

As the inner glove, one using cotton spun yarn, one using a polyester filament, and one using a cellulose filament (see Patent Document 1, etc.) are known.
In addition, a glove made of a synthetic fiber multifilament yarn having a moisture absorption rate of 8% or more at 20 ° C. and 65% RH has been proposed (see Patent Document 2).

  Inner gloves using cotton spun yarn absorb the sweat generated while wearing rubber gloves due to the water absorption of cotton. However, since it is composed of spun yarn, it is bulky and unsuitable for work that requires delicate operations. Further, since lint is generated, there is a problem in using in a clean room.

  Inner gloves using polyester filaments and cellulose filaments are suitable for use in a clean room because lint does not occur. However, since it is poor in elasticity, it does not have a good fit to the hand, and it will bump or slip in rubber gloves.

  In addition, a compound obtained by graft-polymerizing an acidic unsaturated compound such as acrylic acid or methacrylic acid in which a synthetic fiber multifilament yarn is substituted with an alkali metal on the synthetic fiber multifilament yarn has a very high reactive group activity. The polymerized multifilament yarn easily adsorbs heavy metals (Na, K, Ca, Al, Mg, Fe, P, S, Si, Zn, Pb, Cr, Cd, etc.) during work or clean cleaning. . When these heavy metals are adsorbed to gloves worn in a clean room, particularly a clean room such as a semiconductor manufacturing factory, the heavy metal is transferred to a semiconductor, which is a big problem. Furthermore, heavy metal touches the side of the human body to wear, which may cause problems such as rough skin.

  The present invention has been made in order to solve the above-mentioned problems, and the object thereof is easy attachment / detachment, good fit regardless of hand size, and little stickiness when worn. It is to provide seamless knitted inner gloves.

An object of the present invention is a type of inner glove fingertips seamless knitting is exposed, in the longitudinal direction, is 150% or more elongation state, and are stretch-back ratio of 90% or more, the polyurethane yarn as a core yarn, the thermoplastic synthetic fibers made using a covering yarn comprising a sheath yarn least 50 mass% in the inner glove, toe and wrist is knitted rubber, achieved by the inner glove other portion is characterized in mesh knit der Rukoto Is done.
Another object of the present invention is an inner glove of a type in which fingertips of seamless knitting are exposed, and in the vertical direction, the elongation rate is 150% or more and the elongation recovery rate is 90% or more, and polyurethane yarn is used as the core yarn. Achieved by an inner glove characterized in that a covering yarn using a thermoplastic synthetic fiber as a sheath yarn is used by 50% by mass or more in the inner glove, the fingertip part and the wrist part are knitted with rubber, and the other part is mesh knitted. Is done.

  In the present invention, it is preferable that the elongation rate is 400% or more and the elongation recovery rate is 85% or more in the horizontal direction.

  Moreover, in this invention, it is suitable that the elongation rate of a horizontal direction / the elongation rate of a length direction is 2-4.

The inner glove of the present invention is easy to put on and take off, has a good fit regardless of the size of the hand, has no looseness or sagging when worn, and has an excellent wearing feeling. Moreover, it is hard to produce stuffiness when wearing rubber gloves.
Further, wearing the inner glove of the present invention makes it easy to attach and detach rubber gloves and the like.

  Hereinafter, the present invention will be described in detail.

The inner glove of the present invention is formed by seamless knitting, and is characterized by an elongation rate of 150% or more and an elongation recovery rate of 90% or more in the vertical direction. If the elongation is less than 150%, a cramped feeling may be generated when a person with a large hand or a long finger wears, and the size of the hand may not be suitable in terms of product development in a free size.
Further, if the elongation recovery rate is less than 90%, it may not be suitable for reuse after repeated washing. In addition, when a person with a small hand or a finger is worn, sagging may occur at the fingertip.

The inner glove of the present invention preferably has an elongation rate of 400% or more and an elongation recovery rate of 85% or more in the horizontal direction. If the elongation is less than 400%, a cramped feeling may occur when a person with a large hand or a long finger wears it. .
Further, if the elongation recovery rate is less than 85%, it may not be suitable for reuse after repeated washing. In addition, when a person with a small hand or a finger is worn, sagging may occur at the fingertip.

Moreover, it is suitable for the inner glove of this invention that the elongation rate of a horizontal direction / the elongation rate of a length direction is 2-4.
When the ratio of the vertical and horizontal elongation is within the above range, the mesh size of the product becomes appropriate, and the fit and comfort are excellent. Moreover, it becomes an inner glove which does not depend on the size of the hand and the size of the finger, is easy to put on and take off, and fits immediately after wearing.

In the present invention, in order to provide the inner glove with a sufficient elongation rate and elongation recovery rate, a covering yarn having a polyurethane yarn as a core yarn and a thermoplastic synthetic fiber as a sheath yarn is used. The covering yarn may be a single covering yarn or a double covering yarn.
Examples of the thermoplastic synthetic fiber that is a sheath yarn for covering the core yarn include polyamide such as 6 nylon, polyester such as polyethylene terephthalate, polylactic acid, and the like. Among these, polyamide is preferably used.
Examples of the polyamide used in the present invention include nylon 6, nylon 66, nylon 12, nylon 610, or any copolymerized nylon of two or more thereof.

  As the core yarn, a polyurethane elastic yarn having a total fineness of 15 to 35 dtex is preferably used for the inner glove, and a thermoplastic synthetic fiber having 10 to 50 dtex is preferably used as the sheath yarn. A core yarn thinner than the above range is difficult to manufacture and may cause a problem in strength. On the other hand, if it is too thick, the texture and feeling when worn may be a problem. Further, if the thermoplastic synthetic fiber that is the sheath yarn is too fine or too thick than the above range, the texture and texture tend to be poor.

  The core yarn may be monofilament or multifilament (2 to 10). The sheath yarn is preferably 10 to 50 multifilaments. From the viewpoint of texture and water absorption, ultrafine fibers having a single yarn fineness of 1 dtex or less may be used.

Moreover, it is preferable that the frequency | count of winding of the sheath yarn around a core yarn shall be 700-2000 times / m.

The inner glove of the present invention may use 100% of the covering yarn as described above, but may also be used in combination with thermoplastic synthetic fibers such as polyamide yarn and polyester yarn. Even in the middle, polyamide yarn is suitable.
The total fineness of the yarn used is preferably 30 to 85 dtex, and it is preferable to use a yarn having a total fineness comparable to that of the covering yarn.
When other fibers are used in combination, the covering yarn is preferably used in an amount of 50% by mass or more in the inner glove.

The form of the inner glove is a five-finger type, and may be a type that covers all fingers or a type that exposes the fingertips.
The knitting structure of the inner glove is mesh knitted so that air permeability is good.
The wrist part is preferably made of rubber.

  In addition, in the case of a glove that exposes the fingertip, it is preferable that the inner glove is not turned up when the rubber glove is worn over the inner glove by knitting the finger mouth part with rubber. . Moreover, if the length is set so that the fingertip is under the second joint of the finger, the inner glove can be prevented from turning up.

The inner glove of the present invention is manufactured by using a seamless knitting machine.
In the manufacturing method, for example, in a five-finger glove, first the index finger, the middle finger, and the ring finger are knitted, and then the three torso is knitted. Next, a finger bag of the little finger is knitted, and the little finger is joined to the three cylinders to form the four cylinders. Then, after the thumb finger bags are knitted, the four barrels and the thumb finger bags are joined, and the five barrels extending to the wrist are knitted in a seamless shape.

  The inner glove of the present invention may be knitted by alternately arranging covering yarns and normal thermoplastic synthetic fibers for each adjacent yarn feeder.

The inner glove of the present invention obtained as described above is excellent in stretchability, easy to attach and detach, and excellent in wearing feeling. Moreover, it is a free size and can be used without front and back and right and left.
Moreover, the inner glove of the present invention is excellent in washing durability and can be used many times after washing.

  The present invention will be specifically described below with reference to examples. In addition, this invention is not limited to the Example described below.

In the examples, the elongation rate and the elongation recovery rate were determined by the following methods.
1) Elongation rate According to the JIS L-1096B method, the sample width was 25 mm, the length was 80 mm, and the length between marks was 40 mm.
2) Elongation recovery rate According to the JIS L-1096B-1 method, the sample width was 25 mm and the length between marks was 40 mm.
The vertical direction was a load of 14.7N, and the horizontal direction was a load of 4.9N.

[Example 1]
Covering yarn and nylon 6 yarn (56 dtex / 48, Fuji Jiai) covered with polyurethane yarn (22 dtex / 1, Yiwu Yuan) and nylon 6 yarn (33 dtex / 12, Fuji Jiai) ) And a knitted yarn (mesh knitting, wrist knitting and fingertips are rubber knitted) to obtain an inner glove.
The elongation rate and elongation recovery rate of the obtained inner gloves were measured.
The results are shown in Table 1.

[Comparative Example 1]
Using 100% polyethylene terephthalate yarn (56 dtex / 36), a warp knitting machine was used to obtain a mesh-knitted inner glove.
The elongation rate and elongation recovery rate of the obtained inner gloves were measured.
The results are shown in Table 1.

[Comparative Example 2]
Using 100% nylon 6 yarn (167 dtex / 48), a glove knitting machine was used to obtain a flat knitted (wrist rubber knitted) inner glove.
The elongation rate and elongation recovery rate of the obtained inner gloves were measured.
The results are shown in Table 1.

  The inner gloves of the examples were easy to put on and take off, and the feeling of wearing was also good. On the other hand, the inner glove of Comparative Example 1 had little stretch and poor fit, and was loose and slackened, and the feeling of wearing was bad. Although the inner glove of Comparative Example 2 was stretched, it was not sufficient and the wearing feeling was bad.
