Medical covering equipment used for prevention and treatment of medical diseases such as orthopedic diseases, lymphedema and rheumatism caused by muscles, tendons, etc., used to prevent injuries during sports and to hold a part of the human body TECHNICAL FIELD The present invention relates to a sports covering equipment or a covering equipment used for a foundation for adjusting a body shape, and a method for producing the same.

[Conventional technology]

Covering equipment that covers a part of the human body and fixes, supports, compresses, protects, warms, and corrects that part includes shoulders for medical use, sports,
Elbows, hands, hips, knees, feet, etc. joints, chest, belly,
Some are used for the trunk and limbs, such as the hips, forearms, upper arms, thighs, and lower thighs. Various types are known in terms of form, structure, and material from the point of use, the nature of the disease, and operability. Have been. First, the form is roughly classified into a band-like form and a tubular form. Regarding the structural aspect, the body covering the affected part and the rigidity for partially fixing, supporting, pressing, protecting, warming and correcting the affected part covered by the body There is a material in which a high material, a non-stretchable material, a material having a different elasticity, a material having a different cushioning property, a material having a different thickness, and the like are combined, and a belt or the like of the main body is added. In terms of material, in addition to materials having the above-mentioned characteristics, breathable materials,
There are materials having high hygroscopicity, and these are composed of simple or composite materials such as woven fabric, knitted fabric, nonwoven fabric, plastic, and rubber foam.

These covering appliances have high fit, good operability, good wearing feeling, and fix, support, and support only necessary parts.
It is necessary to be able to compress, protect, keep warm, or correct, but since the human body has a different body shape and is not a planar structure, various measures have been taken. For example, in order to improve the fit, we adopted a knitting method for the mounting method, adopted a method of attaching an auxiliary belt to the equipment and tightening it again on the equipment, incorporating a three-dimensional structure in the equipment design, taking into account the directionality of the material, We use techniques for draping and sewing, or combine materials with various characteristics in terms of materials. Further, in order to improve operability, a knitting method in a mounting method is changed to a one-touch method using a hook-and-loop fastener, and a band method is changed to a tubular method.
In addition, three-dimensional sewing technology is used to fix, support, press, protect, heat, correct, etc. only necessary parts, attach auxiliary belts, use thick materials, add pad materials, etc. And other materials are combined.

However, the conventional covering equipment does not always have a sufficient fit for individual patients, and requires a specialized assistant when installing complicated structures, and the weight becomes large, so that long-time wearing is difficult for patients. Painful,
Further, there is no one that mainly acts only on a necessary part.

In addition, the covering equipment for the foundation includes a bra for beautifully adjusting the chest, a bottom girdle and a hip-up girdle for adjusting the waistline and the hipline, and a stocking for improving the legs beautifully and blood circulation. These appliances are mainly made by knitting into a cylindrical shape using nylon yarn or urethane yarn, or sewing a woven fabric. The foundation knitted in a cylindrical shape is partially compressed and changes the supporting force, so the knitting structure changes the size according to the body shape, changes the thickness and type of thread, changes the organization It has a desired function. In addition, the foundation made of sewing includes knitted fabric,
There is a material obtained by combining or overlapping different materials such as a woven fabric and a nonwoven fabric, materials having different physical properties, and materials having different physical properties into a three-dimensional structure.
