Abstract

PROBLEM TO BE SOLVED: To enable to make putting on and off of rubber boots with easy, by applying special heat treatment to a mesh material as a hood material for rubber boots which keep water proof property while maintaining air permeability and keep the shape and elasticity. SOLUTION: A lower brim part of a hood material 3 is fitted outside the opening at a top edge of the rubber boot main body, which has thread thickness of 120 to 200 decitex with a synthetic resin mesh of 15 to 70 wells (wefts) and 12 to 32 coarses (warps) per square inch coated with acrylic resin and further coated with water repellant.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to rubber boots provided with a hood material which can be processed into a waist, can maintain a mold, is breathable and has waterproofness.

[0002]

2. Description of the Related Art As a food material used in conventional rubber boots, there have been synthetic leather and nylon ox. However, synthetic leather has waterproofness and waist, but poor ventilation,
Nylon ox had waterproofness, but poor ventilation and lack of waist.

[0003]

However, in the prior art, when rubber boots are used in a cold region,
Extend the food material. However, the necessary and sufficient conditions for this hood material are that the hood material must be able to maintain a waisted shape because it is folded and placed inside the opening of rubber boots, stretched frequently, and so on. Must. Furthermore, it must be waterproof so that it does not penetrate even when rain or snow is applied, and it must have good air permeability to prevent stuffiness. It is an object of the present invention to provide a rubber boots provided with a hood material that eliminates these contradictory conditions.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a lower edge portion of a hood material is attached to an outer side of an opening at an upper edge of a rubber boots main body, and the hood material has a thickness of a thread. Is 12
15 to 70 wells (welts) and 12 to 32 courses (warps) per square inch at 0 to 200 decitex
A technical measure was adopted in which the synthetic resin mesh was coated with an acrylic resin and then coated with a water repellent.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a rubber boot according to an embodiment of the present invention;

FIG. 1 is a perspective view showing an embodiment of the present invention. In the drawings, reference numeral 1 denotes a rubber boot body in which a lining member made of a thin material such as a knitted fabric or a tricot fabric, or a thick material such as a bore, a felt, or a polyurethane foam is adhered to an inner surface of a rubber member 1a forming a surface. is there. 2 is
The inner is sewn in a shape substantially matching the inner surface shape of the rubber boot main body 1, and is made of a thick material such as a bore, a felt, and a polyurethane foam. 3 is to improve the appearance of the rubber boots with the inner, and at the time of use, to reduce the upper edge of the rubber boots with the through string 4 at the upper side, thereby making the rubber boots waterproof.
This is a hood material in which the lower edge is attached to the outer side of the upper edge of the rubber boot main body 1 in order to maintain cold protection.

Here, the hood material 3 will be described in detail. First, as a material of the hood material 3, a mesh made of a synthetic resin, for example, a mesh made of polyethylene, polyester, or nylon is employed, and a yarn having a thickness of 120 to 200 decitex is used. It is preferable to adopt 15 to 70 yarns and 12 to 32 courses (warp yarns). Particularly good is a yarn thickness of 150 dtex, 27 wells per square inch, course 1
It was confirmed by testing that the mesh was eight.

The hood material 3 is heat-treated with resin in order to make it permeable and waterproof, and not to lose its shape.

[0009] The weight ratio of melamine resin or acrylic resin is 15 to 20%, catalyst is 1.75%, fluorine water repellent is 5 to 7%, and water is 71.25 to 78.25%.
And a heat treatment at about 190 ° C. for about 60 seconds to impregnate the mesh. This is a range in which the strength of the waist, breathability, and waterproofness have been cleared as a result of various experiments. By doing so, the mesh is coated with a melamine resin or an acrylic resin so that the hood member 3 has a waist to prevent the hood material 3 from getting out of shape, and the mesh maintains the air permeability. And it has waterproofness by coating with a water repellent.

When cotton is adopted as the material of the mesh of the hood material 3, the resin to be coated is
This is performed with an acrylic resin. This is because melamine resin is not suitable in the case of natural fibers.

[0011]

According to the present invention, as a result of employing the above configuration,
The following effects can be obtained. (1) As a hood material for rubber boots, by performing a special heat treatment on the mesh material, it is possible to maintain waterproofness while being breathable, and to maintain the mold by holding the waist, -The operation of the sewing can be performed extremely well.
