Next, the set woven fabric 10 is immersed in the composition 40 contained in the dipping tank 50 as shown in FIG.

At this time, the composition is immersed for 5 to 20 seconds depending on the shape and thickness of the dipping treatment to form a rubber layer by thermal coagulation of the surface of the woven fabric.

Next, the dipped weave 10 is preliminarily hardened for 20 minutes at 100 ° C. (S3).

Next, the dipped weave 10 is extracted as shown in FIG. 4C (S4).

Next, the product with the precured coating layer formed as described above is taken out of the dipping mold and soaked for about 30 minutes in water or hot water at room temperature to homogenize aging and softening of the coating layer (S5).

This prevents the coated rubber layer from spreading evenly when it is set in the setting mold, which is the next process, and prevents the thickening or thinning of the coating, and also dissolves and removes impurities that adversely affect the final product. No cleaning process is required.

Next, the aging material 10, which is sufficiently matured and softened in the process, is reset to a setting mold manufactured in a predetermined form (S6).

After masking as described above, as shown in FIG. 4B, when the masking part of the sock is immersed in the dipping tank 50 containing the composition 40 mainly composed of synthetic resin such as latex rubber and polyurethane, the protective paper 20 is provided. Through the holes 21 formed in the wear resistant coating layer is deposited on the surface of the socks.

The wear-resistant coating layer can be continuously dipping instantaneously by employing mechanical means in the mass production step.

At this time, the composition is immersed for 5 seconds to 20 seconds depending on the shape and thickness of the dipping to form a wear-resistant coating layer by thermal coagulation of the surface of the woven fabric.

Next, the socks 10, which have been treated as described above, are subjected to a primary precure process for 20 minutes at 100 ° C.

Next, as shown in FIG. 4C, the protective paper 20 attached to the dipped socks 10 is separated, soaked for about 30 minutes in water or hot water at room temperature, and the coating layer is homogenized, aged, softened, and then set again. It is possible to obtain a sock provided with an anti-wear coating layer by resetting the mold and performing a secondary curing treatment at 100 ° C. to 120 ° C. for 40 to 60 minutes.

In this case, the dipping of the socks may be performed on the entire bottom surface of the socks as shown in FIG. 5A, and may also be selectively applied to the toe and the back of the high wear level of the socks as shown in FIG. 5B. In addition, as shown in FIG. 5C, the toe part, the bottom part of the foot, and the heel can be selectively dipped to form an anti-wear coating layer 41.

That is, since the wear-resistant coating layer 41 can easily adjust the thickness of the site receiving a lot of force, such as the heel, to a desired degree, it can be used for the purpose of preventing a special sport or deformed foot.

In addition, when the woven fabric is a garment, it may be selectively dipping on both elbows and knees that are relatively well worn.
