Description

Fabric with excellent elasticity, breathability, and pressure, and clothing including muscle compression lines using the same {FABRICS WITH HIGH ELASTICITY, BREATHABILITY, AND COMPRESSION, AND GARMENTS COMPRISING MUSCLE COMPRESSION LINES USING THE SAME}

The present invention relates to a fabric and a clothing including the same, and more specifically, to a fabric having excellent elasticity, breathability, and compression force, and a clothing including a muscle compression line using the same.

In the human body, different muscles develop in the upper and lower bodies depending on the amount of exercise and the type of exercise. In general, the body is maintained in a rigid posture for a long time, undergoes severe stress, physical labor or exercise, or due to illness or aging. Muscle pain can occur in various areas of the body.

As one of the methods of physically alleviating such muscle pain, clothing constituting muscle compression has been used. Conventional clothing that composes muscle compression uses a method of imitating its shape on clothing by referring to a method such as kinesio taping. In general, it is a structure in which a unique viscous material such as silicone is applied and printed on one side of the fiber. Done. However, clothing with silicone printed on the surface of the clothing has a problem in that it does not sufficiently reflect the functional part of the muscle compression because it focuses on the external design.In the clothing printed on the inner surface of the clothing, the silicone directly contacts the skin, resulting in muscle contraction. However, due to the viscosity of the silicone, it is strongly adhered to the skin, which makes it very uncomfortable to wear, and the sweat generated during the activity is not smoothly discharged to the outside, resulting in side effects such as contact dermatitis.

Korean Patent Laid-Open Publication No. 10-2009-0107989 discloses a sports typing tights in which a resin and a rubber material made of a silicone or urethane elastic material are printed and coated in multiple layers on the inner or surface of a high-elastic fabric. No. 2015-0017279 discloses a functional compression clothing printed with a silicone sculpting layer through which a through hole for ventilation and sweat discharge is made on the inner surface of a high-elastic synthetic fiber knitted fabric.

However, in the prior art, as a garment in which silicone is printed on an inner surface or one surface of an elastic fabric, there are still problems such as a lack of pressing force, an uncomfortable fit, and poor ventilation.
