DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing gloves which can be released from a glove mold without using a release agent or the like, and which can be easily attached to and detached from a user's hand. About gloves.

[0002]

2. Description of the Related Art Conventionally, vinyl chloride resin gloves that require flexibility are generally prepared by blending a plasticizer in an amount of 100 to 150 parts by weight with respect to 100 parts by weight of a vinyl chloride resin. Since the flexibility is maintained, the plasticizer protrudes from the surface of the glove, and the adhesive and blocking properties remain strong.

In particular, in the case of gloves formed only of a vinyl chloride resin layer, that is, gloves having no backing such as a cloth surface or flocking, when the gloves after the final melting step are released from the glove mold, the gloves are used. The gloves on the mold must be cooled down to a suitable temperature, and the mold must be released by turning the glove surfaces in the direction of the fingertips of the glove while flipping the gloves while gripping the cuffs of the gloves.

[0004] At this time, in order for the glove to slide against a strong frictional resistance while expanding around a large back including a thumb due to elasticity of the glove, the surface of the glove turned upside down requires Since it is necessary to suppress the tackiness and blocking properties as much as possible to make the gloves slippery, the surface of the gloves may be ground with a release agent (fine lubricating powder such as talc or mica powder) or paraffin Or other lubricants.

DETAILED DESCRIPTION OF THE INVENTION

[0005]

[Industrial applications] However, gloves used in various precision equipment manufacturing plants and food manufacturing plants, which have been increasingly used in recent years, are thin, fit to the hands, have a sharp feel, are hard to slip, and are reliable. There is a demand for gloves that can be grasped and that are hygienic and that do not allow the attachment of dust that is invisible to the naked eye, so-called dust-free gloves.

[0006] For this reason, there is a problem that, for hygiene purposes, gloves that have been ground with a release agent that may be scattered during use or gloves that have a lubricant applied to the outer surface of the glove cannot be used.

In addition, it is particularly thin and fits the hand, and
In the case of gloves made of a vinyl chloride resin that can provide a sharp feel, there is a problem that hand insertion and removal cannot be performed easily.

[0008] Gloves made of vinyl chloride resin have poor air permeability because they do not have moisture permeability, so that the inner surface of the glove becomes wet with sweat and the hands and fingers are easily slipped in the glove, and the gloves to be handled can be removed. There is also a problem that it can be dropped.

[0009]

Therefore, according to the present invention, a glove mold is dipped in a soft vinyl chloride resin sol, the glove mold is pulled up from the soft vinyl chloride resin sol, and the soft chloride adhered to the surface of the glove mold. A glove base layer is formed by heating and gelling the vinyl resin sol to form a glove base layer, and the glove mold is formed by dispersing a particulate incompletely crosslinked vinyl chloride resin into a plasticizer, solvent, and diluent. Immersed in a mixed solution of a glove base and a stabilizer.The glove mold is pulled up from the mixed solution, and the incompletely crosslinked vinyl chloride resin adhering to the surface of the glove base layer is heated and gelled and melted to be integrated with the glove base layer. It is another object of the present invention to provide a method for producing a glove, which is characterized in that the glove is inverted and removed after cooling.

Further, a glove manufactured by the above-described method for manufacturing a glove, that is, a finely-divided incompletely crosslinked vinyl chloride resin having a surface lubricity on a fine wrinkle-like uneven surface formed on the inner surface of the glove base layer is formed into a thin layer. The attached gloves also have features.

[0011] The composition of the soft vinyl chloride resin layer is a resin for general paste, an uncrosslinked vinyl chloride resin generally used such as dipping, slash, coating, etc .; a plasticizer; a stabilizer; Depending on the pigment, filler, reinforcing agent, and as a processing aid, a gelling agent,

(See (g)), the incompletely crosslinked vinyl chloride resin 8 adhered to the surface of the glove base layer 4 is heated and gelled and melted (see FIG. 1 (h)).

At this time, the degree of crosslinking of the incompletely crosslinked vinyl chloride resin 8 is set to 80%, and the average particle size is set to 1 μm.

After removing the sagging at a constant pulling speed, as shown in FIG. 1 (h), a heating device 7 such as a hot air circulating furnace is used to perform a heat treatment at a hot air temperature of 170 to 200 ° C., for example. Then, the incompletely crosslinked vinyl chloride resin component is gelled together with the glove base layer 4 and melted.

In such a state, the surface of the glove base layer 4 becomes a fine wrinkle-like uneven surface 4a as shown in FIG. 2, and the incompletely crosslinked vinyl chloride resin 8 in the form of fine particles is formed as shown in FIG. It adheres uniformly on the fine wrinkle-like uneven surface 4a without any gap, and has a thin layer shape. The diluent and the solvent are vaporized and scattered, and the plasticizer and the stabilizer are absorbed by the glove base layer 4. .

The glove A manufactured as described above is
Cool to an appropriate temperature and release from glove mold 3 (see FIGS. 1 (i) (j)).

At the time of releasing the glove, the glove A is turned upside down while grabbing the cuffs of the glove A and turning the glove A toward the fingertip of the glove A while sliding the surfaces of the glove A toward each other. As shown in FIG. 3, the particulate incompletely cross-linked vinyl chloride resin 8 adheres, so that the frictional resistance is small. Therefore, the mold release is smoothly performed without using a release agent or a lubricant. can do.

[0034]

According to the present invention, the following effects are produced.

Since a glove having an incompletely crosslinked vinyl chloride resin in the form of fine particles adhered to the outer surface at the time of release can be manufactured, it can be released easily without using a release agent or a lubricant. Can be gloves. For this reason, such gloves can be used without any problem even in a severe working environment with hygienic conditions such as various precision equipment factories and food manufacturing factories.

When gloves are used, since the incompletely crosslinked vinyl chloride resin in the form of fine particles adheres to the inner surface of the gloves, the gloves should be thin, fit to the hands, and have a sharp feel. In addition to this, insertion and withdrawal of the hand into the glove can be easily performed.

Gloves are not breathable,
The fine wrinkle-shaped uneven surface densely formed on the inner surface of the glove base layer fits well with the skin of the fingers when grasping the handled object, and the concave portion of the wrinkle-shaped uneven surface is well drained and adhered. To disperse sweat water in all directions and at the same time expose incompletely crosslinked vinyl chloride resin fine particles on the surface of the wrinkle-like uneven surface, so as not to leave a water film that acts as a lubrication between the glove base layer and the finger skin In addition, there is no problem that the hand slips inside the glove, and therefore, there is no problem of dropping the handled material.

The fine particles of the incompletely crosslinked vinyl chloride resin which forms the inner surface of the glove which comes into contact with the skin of the hand are hard thin layers, but the base layer of the glove has a fine wrinkle-like uneven surface. It is possible to maintain its own flexibility, and to easily handle the items to be handled.
