Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing vinyl chloride work gloves with reinforced hems.

Conventionally, this kind of work gloves made of vinyl chloride has been made by making fiber gloves sewn from knitted fabric such as stockinette knitting, milling knitting, etc., or by directly knitting seamless fiber gloves, covering these in a mold, and applying vinyl chloride resin liquid. The fiber gloves were manufactured by coating and molding a vinyl chloride resin layer on the fiber gloves by immersing them in water or coating them with a vinyl chloride resin solution.

However, in such conventional work gloves made of vinyl chloride, the vinyl chloride resin layer was thick and the usability was extremely poor.

In order to improve usability, it is necessary to form the vinyl chloride resin layer as uniformly and thinly as possible.

In response to this, the present inventor has proposed a method for manufacturing work gloves having a flexible coating, in which a vinyl chloride resin paste is applied to a textile glove that has been subjected to an oil-repellent treatment in advance.

(Patent Application No. 57-52300) This made it possible to make the resin layer much thinner than before, but on the other hand, it was physically possible to make the vinyl chloride resin layer at the hem of the glove. The thickness of the vinyl chloride resin layer at the hem should be avoided to be thinner than the fingertips, especially when manufacturing work gloves with a thin, flexible and stretchable vinyl chloride resin layer. As the gloves become thinner, if thin sewn fiber gloves or seamless fiber gloves are used as a base, tears may occur from the hem, impairing the glove's functionality, or the hem may curl inward when the gloves are put on. It was found that there was still room for improvement in that the system became easily damaged and extremely difficult to use.

Another possibility is to glue and weld a thick piece around the entire circumference of the hem of the glove to increase the thickness of the hem, but this method increases the number of work steps and does not allow the gloves to be beautifully finished. , and also had the disadvantage of poor usability.

This invention was made by focusing on the drawbacks of conventional work gloves, and its purpose is to improve the thickness of the hem of work gloves formed with a vinyl chloride resin layer. To provide a method for producing work gloves made of vinyl chloride, which can uniformly and quickly form a thick layer, thin the vinyl chloride resin layer to have elasticity and flexibility, and have a reinforced hem. be.

An embodiment of the method for manufacturing work gloves according to the present invention will be described below with reference to FIGS. 1 to 7.

Reference numeral 1 indicates a knitted glove fabric in which fiber threads 2 are knitted, and reference numeral 3 indicates a knitted glove fabric in which fiber threads 2 are woven.In each case, the distance between adjacent fiber threads 2 is 1:5 to 4. It is formed within 0 times.

Reference numeral 4 denotes an oil-repellent treatment layer formed on the outer surface of the fiber thread 2 with an oil-repellent agent such as fluorine, silicone resin, etc., and 5 denotes a fiber glove woven with a glove knitted fabric that has been surface-treated with these.

Here, in the oil grinding layer 4, the vinyl chloride resin 7 containing an oil-based plasticizer is applied to the fiber yarn 2 due to its oil-repelling effect.
In order to prevent anything from entering the gap between the gloves, it is formed so thin that it appears as if it were framed by the fiber threads 2 of the knitted glove fabrics 1 and 3.

(See Figures 3 and 4) If the spacing between the fiber threads 2 exceeds 4.0 times the thickness, the weight of the vinyl chloride layer will become excessive and the thickness will increase. This is the limit.

As shown in FIG.
The fingertips are then immersed into a bath 8 of vinyl chloride resin 7.

Note that the vinyl chloride resin 7 may be applied by spraying or dropping.

Thereafter, as shown in FIG. 6, the mold 6 is pulled up from the melt tank 8, and the vinyl chloride resin applied as described above is caused to flow down from the hem toward the fingertips with the fingertips facing downward. Of the resin liquid present at each interval between the oil-based fiber threads, use your fingertips to remove the resin liquid in excess of the amount required to cross-link the surfaces between adjacent fiber threads with a thin film with elasticity and flexibility. Drip and remove.

Then, in this state, the wall thickness of the vinyl chloride resin finger 7 in the part A in FIG.

(See Figures 3 and 4.) Next, as shown in Figure 7, the mold 6 is shaped so that the fingertips are not higher than the hem, and while rotating it, the hem 9 of the glove is molded. 20-30 to
By applying the vinyl chloride resin 7 over a width of 10% by dripping or spraying, a reinforcing vinyl chloride layer in the form of a band is formed on the hem 9, which is thicker than the other parts and has a uniform thickness. is formed, and other parts are also formed in a uniform layer.

Thereafter, by heat-treating the vinyl chloride resin layer, a work glove with a reinforced hem portion that is highly flexible and stretchable is manufactured.

As described above, according to the present invention, in a textile glove made of knitted or woven fabric, the distance between adjacent fiber threads is within 4.0 times the thickness of the fiber threads, the outside of each fiber thread is A process of forming an oil-repellent layer on the surface with an oil-repellent agent, and applying vinyl chloride resin to the fiber gloves on which the oil-repellent layer has been formed, and then attaching the hem part with the fingertips facing downward. By flowing the applied vinyl chloride resin from the fingertips toward the fingertips, the resin liquid intervening between the oil-repellent fiber threads makes the surfaces between adjacent fiber threads stretchable and flexible. The step of removing the resin liquid from the fingertips in excess of the amount required for crosslinking with a thin film, and the step of removing the fiber gloves from which the excess resin liquid has been removed in such a way that the fingertips are not higher than the hem. A hem portion comprising the step of: forming a band-shaped reinforcing vinyl chloride layer on the hem portion by applying vinyl chloride resin to the hem portion by a spray method or a dripping method while rotating the hem portion while keeping it in a horizontal state. This method of manufacturing reinforced vinyl chloride work gloves provides the following effects.

(1) Since the spacing between adjacent fiber threads is properly regulated and the fiber threads are treated with oil, there is no possibility that too much resin liquid will accumulate in the spaces between the fiber threads. It is also possible to prevent the vinyl chloride resin liquid, which has a composition of can be made much less.

(2) Therefore, by letting the excess amount of the resin liquid flow down toward the fingertips, the resin can be quickly removed and a crosslinked resin thin film can be easily formed between the fiber yarn surfaces.

(3) Furthermore, since the resin liquid is applied only to the hem portion in a substantially horizontal state, the hem portion, which tends to become particularly thin, can be reinforced to any desired thickness and width.

In addition, the resulting product does not have the stiff feeling of conventional vinyl chloride work gloves, and does not reduce the delicate feel of the fingertips.

In other words, it fits well in the hand, is stretchable and flexible, and is easy to use.

■ Unlike conventional rubber gloves or gloves made only of PVC, they are lined with fiber yarn, so they are not only waterproof, but also strong and cushioned.

Therefore, (b) There is no risk of hand injury due to the object being held.

(b) Good heat retention.

(c) Even if you sweat, it absorbs water so it won't get sticky.

■ The hem is strong and durable, and the hem does not get rolled up when worn.

■ The exterior is also beautiful.
