As described above, in the conventional vinyl chloride glove, the surface of the semi-cured vinyl chloride resin (glove inner surface) is used to implant the pile on the inner surface of the glove body made of the vinyl chloride resin. It is necessary to attach a resin solution to be used as an adhesive. Therefore, at the time of producing the above-mentioned vinyl chloride glove, at least two immersion steps were required. The inventor of the present application has repeatedly conducted experiments to reduce the number of steps for manufacturing gloves made of vinyl chloride resin by implanting piles on the inner surface of the glove body as described above. A pile can be implanted on the inner surface of a glove body made of a vinyl chloride resin without performing a step of dipping in a resin solution to be used.

An object of the present invention is to provide a method for manufacturing a vinyl chloride glove in which a pile is implanted on the inner surface of a glove body as described above, and a resin solution for bonding a pile which has been used in a conventional manufacturing method. An object of the present invention is to reduce the labor and time required for manufacturing the glove by omitting the step of immersing the glove.

[0007]

According to the method of the present invention for producing gloves made of vinyl chloride, a heated glove mold is immersed in a vinyl chloride resin solution kept at a predetermined temperature and pulled up. A vinyl chloride paste is adhered to the surface to form a film, and the vinyl chloride paste film is heated at a predetermined temperature for a predetermined time to be semi-cured. The glove mold is placed in an electric field created between an electrode and ground. At the same time as rotating, the pile is evenly spread over the electrodes and allowed to fall.The piles are aligned by the electric field and pierce and adhere to the surface of the semi-cured vinyl chloride resin to be attached to the glove mold. At first, after that, the glove mold is cured with vinyl chloride adhered thereto.

According to the above-mentioned means, when the glove mold heated to an appropriate temperature is immersed in a bath of a vinyl chloride resin solution kept at a predetermined temperature and pulled up, the surface of the glove mold becomes a vinyl chloride paste. Adheres to form a film. The vinyl chloride paste applied to the glove mold is preliminarily dried and then heated in an atmosphere at a predetermined temperature for a predetermined time to be in a semi-cured state.

Then, with the vinyl chloride semi-cured to an appropriate stage, the glove mold is moved into an electric field created between the electrode and the earth and rotated. At the same time, the pile is evenly spread from above the glove mold and dropped. When the falling pile reaches between the electrode and the ground, an electric field generated between the electrodes causes the falling piles to face the ground all at once, thereby being aligned. Then, it adheres to the surface layer of the semi-cured vinyl chloride layer (the inner surface of the glove body) in a semi-cured state, which adheres to the glove mold that passes while rotating in the electric field, and covers the entire surface. In other words, at this stage, the surface of the vinyl chloride film is in a semi-cured state to such an extent that the aligned falling pile is pierced and stopped. Thereafter, the vinyl chloride film adhered to the glove mold is completely cured. Then, the film that becomes the glove body and adheres to the glove mold is reversed and released. Numerous piles are implanted on the inner surface of the glove body molded as described above while piercing the inner surface of the glove body. In addition, the pile in which the hair is implanted is implanted so that the vinyl chloride film in the area pierced into the inner surface of the glove body is completely cured and adhered so as not to come off.

A glove made of vinyl chloride according to claim 3 is a glove made of vinyl chloride manufactured by the manufacturing method according to claim 1 or 2, wherein the glove body has a sole vinyl chloride resin layer. It consists of flocking implanted by piercing the surface layer of the vinyl chloride resin layer, and is configured without adding any additional elements other than the above-described vinyl chloride resin layer element and the flocking element. According to the above-described means, the vinyl chloride resin layer constituting the glove body of the vinyl chloride glove is the only resin layer to which no adhesive resin layer or film resin layer is added, and is formed as a single layer. You. In addition, the surface layer of the vinyl chloride resin layer, that is, the surface layer on the inner surface side of the glove body (the portion on the surface side of the vinyl chloride layer) has a flocking planted by piercing a pile. That is, the vinyl chloride glove of the present invention includes additional elements such as an adhesive resin layer for adhering the flocks and a resin layer for the film, in addition to the basic elements consisting of the elements of the vinyl chloride resin layer and the flocks. It is configured without. However, the above-mentioned additional elements are only basic elements constituting the gloves made of vinyl chloride, and do not include a treatment agent layer or powder for improving the slip.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a vinyl chloride glove A produced according to the production method of the present invention. This glove A can be used for water work such as dishwashing, washing, and car washing, and for gloves.
It is used when performing work such as denning,
The glove body a is formed of vinyl chloride resin, and countless piles b are entirely implanted on the inner surface thereof.

As shown in FIG. 2, in the glove A made of vinyl chloride, a glove mold C is immersed in a vinyl chloride resin solution P1, pulled up, and a vinyl chloride paste P2 serving as a glove body a is formed on the surface of the mold C. Is formed. The glove mold C is formed substantially in the same shape as the product using ceramics or metal, and a pattern such as a pattern formed on the surface of the glove to be a product or a non-slip is formed on the surface thereof. In addition, glove mold C
The glove mold C is manufactured at the time of manufacturing by controlling the temperature.
Is used by heating to about 50 ° C. The glove mold C heated as described above is immersed in a resin bath of a vinyl chloride resin solution P1 kept at a predetermined liquid temperature, for example, about 35 ° C., and is pulled up, as shown in FIGS. 2 (a)-(b)-(c). . On the surface of the glove mold C pulled up from the vinyl chloride resin solution P1, a vinyl chloride paste P2 to be the glove body a adheres to form a film. Incidentally, as an example of the above-mentioned vinyl chloride resin solution, various additives commonly used, such as a plasticizer, a stabilizer, a gelling agent, and a pigment, are blended into a vinyl chloride paste resin, and the viscosity is 4000. 110000 cps.

The vinyl chloride paste P2 formed on the surface of the glove mold C as described above is preliminarily dried and then heated at a predetermined temperature for a predetermined time, so that when the surface is semi-cured moderately, the pile b setting process is performed. (Fig. 2
-C). Further, as described above, the conditions for moderately curing the surface layer of the vinyl chloride paste P2 adhered to the surface of the glove mold C, that is, the heating temperature and the heating time, the upper limit is 200 ° C. for 20 minutes, and the lower limit is 100 ° C. And set it within this range. This is an important factor. That is, if the heating temperature and the heating time exceed the above upper limits, the vinyl chloride resin is decomposed and deteriorated. If the heating temperature and the heating time are below the lower limits, physical properties are deteriorated due to insufficient curing.
Further, the setting range of the above-mentioned heating is also an element which satisfies the condition for piercing and fixing the pile b to the surface layer of the semi-cured vinyl chloride paste by the flocking process of the pile b as described later. Also, preferably, the above-mentioned conditions of the heating temperature and the heating time are set within the range of 10 minutes at the upper limit of 200 ° C. and 3 minutes at the lower limit of 110 ° C., and particularly good results are obtained.

The vinyl chloride paste P2 film that has been semi-cured under the above-described conditions is transferred to a pile b flocking process together with the glove mold C as shown in FIG. As described above, the glove mold C to which the vinyl chloride paste P2 in the semi-cured state is applied passes between the electrode d1 which is held horizontally at an appropriate interval vertically and the ground electrode d2. I do. The electrode d1 and the earth-side electrode d2 are substantially net-shaped frames formed using a metal wire, and are arranged at intervals in the vertical direction to form a flocked space through which the glove mold C passes. is there. Further, a spray container e for storing the pile b is provided above the electrode d1. The sprinkling container e is provided with a fine net-like body passing through the pile b little by little on the bottom surface of the container like a sieve, and the same sprinkling container e is horizontally vibrated finely so that an appropriate amount of the pile b is evenly sprayed from the bottom surface. It is configured to do so.

On the other hand, the above-mentioned electrode d1 and the earth side electrode d
2, a voltage of 10,000 to 50,000 volts is applied.
An electric field d is generated between 1 and d2. The electric field d is
1. A vinyl chloride paste of a glove forming mold C which is linearly generated from 1 to the ground side electrode d2, falls vertically in the electric field d, passes through all piles b in a vertical orientation, and rotates in the electric field d. Poke into the surface layer of P2.

The glove mold C is rotated several times in an electric field d to obtain a semi-cured vinyl chloride paste d2.
The pile b is evenly and densely implanted on the entire surface (FIG. 3). The vinyl chloride paste P2 of the glove mold C having the pile b implanted on the surface (glove inner surface) as described above is heated again to completely cure the vinyl chloride resin film. Thereby, the pile b pierced into the surface layer of the vinyl chloride resin
The base end portion is fixed by complete hardening of the resin, and the hair is reliably implanted. Then, after a cooling time, the glove body a to be adhered to the surface of the glove mold C is released from the mold and the surplus portion formed at the opening edge is cut to complete. Actually, the electrodes d1 and d2, the spray container e, and the like are housed in a closed space. Also, both electrodes d1 and d1 were not implanted on the surface of the vinyl chloride paste P2 of the glove mold C.
The pile b passing through d2 is sucked and returned into the spraying container e.

As described above, the setting range of the heating temperature and the heating time is set to satisfy the condition that the pile b is pierced into the surface layer of the semi-cured vinyl chloride paste P2 and securely fixed by the flocking process of the pile b. Element. That is, in order to implant the pile b on the surface of the vinyl chloride paste P2, it is important to control the temperature based on the above-mentioned temperature setting range. For example, if the heating is performed outside of the set range, the surface layer of the vinyl chloride paste P2 is hardened too much and the pile b cannot be sufficiently pierced, and the planted pile b falls off. Conversely, if the heating is insufficient, the surface layer of the vinyl chloride paste P2 is too soft, and the pierced pile b2 falls down or hardens while being deeply buried in the surface layer of the vinyl chloride paste P2. The texture when doing it worsens.

The upper limit of the thickness of the resin forming the glove body a to be immersed and molded as described above is 1.5 mm, and the lower limit is 0.1 mm.
Is preferably within the range. That is, if the resin thickness is larger than the upper limit of the above range, the texture of the glove is impaired, and if the resin thickness is smaller than the lower limit, pinholes and the like are liable to occur, so that sufficient strength as working gloves cannot be secured. In the above-described embodiment, the glove body a was formed by one dipping.
The glove body may be formed by performing the rotation repeatedly.

In the vinyl chloride glove of the present invention, the thickness of the pile b in the state where the pile b is implanted is also an important factor.
Table 1 below shows the thickness values of the gloves manufactured by the manufacturing method of the present invention, and three places A to C were measured near the cuffs (around the middle of the cuffs and wrists) where the thickness was average. This is the result. In addition, the measurement method was a thickness (measured according to JISK6301) having a scale of 0.01 mm minimum, a circular pressurized surface with diameters of 5 mm and 10 mm, and a load of 80 gf. The pile implanted in the tested gloves is 0.5 mm, but the pile is crushed by the pressure applied at the time of measurement.

[Table 1] In addition, in addition to the above-described measurement method, when a glove cross-section is measured by eye measurement using a magnifying glass and a steel wire having a diameter of 0.5 mm, which is a dimensional reference, that is, when measurement is performed in a state where hair implantation is not compressed ( Before and after flocking), the following measurement results were obtained. The conventional gloves had an average of 0.3 to 0.7 mm before implantation and 0.4 to 0.8 mm after implantation. The gloves of the present invention had an average of 0.2 to 0.6 mm before implantation, and an average of 0.3 to 0.7 mm after implantation. Therefore, it has become possible to manufacture a vinyl chloride resin glove, which has not existed conventionally, that is, a glove body a having a thickness of 0.2 to 0.3 mm.

[0020]

As described above, according to the method for producing gloves made of vinyl chloride of the present invention, a film is formed by adhering a vinyl chloride paste to the surface of a glove mold by dipping in a vinyl chloride resin solution. After semi-curing the film moderately, using the electric field generated between the electrode and the ground, align the piles that are scattered from above and fall, and pierce the piles into the surface of the vinyl chloride resin (the inner surface of the glove). By completely curing the coating, the base end of the pile pierced into the inner surface of the glove body is fixed to the surface layer of the resin to implant the hair. Therefore, conventionally, at least two immersion steps performed when manufacturing a vinyl chloride glove, that is, an immersion step for attaching a vinyl chloride paste to the surface of a glove mold to form a film that becomes a glove body, Of the above-mentioned dipping process for adhering the resin solution for bonding the pile to the surface of the vinyl chloride paste film (the inner surface of the glove body), the latter dipping process can be omitted, and once the glove body is formed. It is possible to implant a pile on the inner surface of the glove body only by the dipping step.

According to a second aspect of the present invention, the upper limit of the heating temperature and the heating time at the time of semi-curing the vinyl chloride paste formed on the surface of the glove mold is 200 minutes at 200 ° C., and The lower limit is 2 minutes at 100 ° C. Thus, by setting the range of the heating temperature and the heating time, which are elements for appropriately semi-curing the vinyl chloride paste formed on the glove mold, within the above-described range, the piles are aligned by using the electric field. For the first time, it is possible to pierce the surface of the vinyl chloride paste. In other words, the above-described conditions are indispensable conditions for establishing pile flocking.

According to a third aspect of the present invention, there is provided a vinyl chloride glove manufactured by the method of the first or second aspect.
The glove body comprises a sole layer of a vinyl chloride resin layer, and a flocking planted by piercing the surface layer of the vinyl chloride resin layer. It is configured without adding. Therefore, it is possible to omit the second immersion step of immersing in the resin solution for bonding the pile or the resin solution for the coating performed after the flocking, so that the above-described effects can be obtained in the manufacturing process, and the resin solution for bonding can be obtained. Since the layer of the glove is eliminated, the thickness of the glove main body can be appropriately reduced while the pile is implanted on the inner surface of the glove main body, and an unprecedented soft feeling of use is obtained.

According to a fourth aspect of the present invention, there is provided a glove made of vinyl chloride, wherein the thickness of the main body of the glove made of vinyl chloride is 0.1 mm to 1.5 mm. Good texture and good usability are obtained while securing the strength required for the main body.
