The present invention relates to a non-woven fabric for hemp insoles and functional insoles made therefrom, and more particularly, it contains anti-microbial, durable and environmentally friendly hemp fibers suitable for use in insoles and inner skin of various footwear such as shoes and sneakers. It relates to a non-woven fabric for the main sole made of a conventional fabric and a functional insole made therefrom.

In general, when a person walks or runs, a person wears shoes as a means for protecting ankle or waist by absorbing a shock received from the ground and protecting a foot from a dangerous object.

These shoes are usually composed of the upper and the window, and the upper is referred to the upper part based on the insole, and is composed of the front part, the side part, the neck, the end part, the tongue and the part, and the window is in contact with the sole when the shoe is worn. And insoles and soles underneath.

Here, the insole and the insole are injection-molded with a soft synthetic resin material such as polyurethane so as to have a form in which the sole is in close contact, and a nonwoven fabric or cotton, etc., which absorbs sweat on the upper surface thereof with an adhesive, when the shoe wearer is walking To cushion the shock and improve the fit of the shoe.

However, the existing shoe insole has a limit of absorbing the sweat from the sole of the shoe wearer, causing a discomfort in the user and a bad smell occurs when worn for a long time. In other words, when the shoes are worn for a long time, the bacteria grow by the sweat from the feet and foreign substances in the shoes, creating a substance called 'iso valeric acid' and causing a bad smell. There is a problem of breeding and causing diseases such as athlete's foot.

On the other hand, the fiber of hemp is much longer than other fibers, especially 10 times longer than cotton. For this reason, hemp has been used as a rope material in the past. It is becoming. Burlap has up to 20 times faster water absorption and discharge than cotton, and after washing or washing some antimicrobial fabrics, burlap suppresses fungi that remain unchanged in the fiber itself. For example, if you put the wet cloth and cotton cloth soaked in a warm place for a long time, the smell of the fungus in the cotton cloth will cause a bad smell, but the burlap cloth will not.

Burlap has a sun protection function that penetrates into the flesh generated from the sun, and hemp can grow very well without pesticide spraying such as insecticides or herbicides in any soil if the weather conditions are suitable. The production base can also protect our forest resources because it can produce 5 times more than the wood pulp.

Hemp is called hemp and is the oldest fiber. Hemp is a bast fiber obtained from hemp plants. Hemp is the hardest and toughest among the fibers, and hemp fiber is composed of about 77% of fiber, which has a high purity. Hemp fibers have a very unique structure in which long hollow pipes are entangled like spider webs. Therefore, due to these structural characteristics, it has the characteristics of controlling moisture and heat, as well as absorbing power, discharging power, and sound insulation, which are about 20 times faster than cotton.

In addition, the summer red ginseng, bed sheets, duvets, yo especially used as veterinary clothing. Burlap contains antibacterial and anti-toxic properties, preventing the infestation and proximity of germs (99.6% antimicrobial activity, 87.7% far-infrared radiation and UV and water wave blocking).

In addition, the moisture absorption, divergence, and breathability of the fibers are superior to those of other fibers, and they are strong in salt and thermal conductivity, which is cool. Its durability against friction is long, its lifespan is long, and its strength against water is large, so it is less damaged when washing.

Conventionally, insoles made of plastic or bamboo containing or attached jade and charcoal were used for the purpose of preventing various skin diseases such as foot odor or athlete's foot by wearing shoes. Or there was a limit to remove the smell.

Therefore, it is a reality that the development of insole nonwoven fabric using hemp and hemp having the advantages as described above is required.

Accordingly, the present invention is to solve the problems described above, weaving or knitting by using a weaving machine or knitting machine using a polypropylene fiber or polyester fiber mixed with hemp having excellent breathability and antibacterial and deodorizing effect It is an object of the present invention to provide a non-woven fabric for use in a non-woven fabric and a functional insole manufactured from the non-woven fabric, which is low in cost and has excellent fit and cushioning properties.

In order to achieve the above object, the non-woven fabric for the main sole according to the preferred embodiment of the present invention, 10 to 20% by weight of polypropylene fiber as the upper surface of the bottom of the nonwoven layer of the sole shape that the entire sole can reach, polyester fiber It is characterized in that it comprises a hemp nonwoven layer blended with 20 to 30% by weight and 50 to 70% by weight hemp fiber.

In addition, the non-woven fabric for mind brush according to another embodiment of the present invention, activated carbon urethane foam layer formed to mitigate the impact when walking or running using a material having an elastic force to the upper side of the non-woven fabric layer; It is characterized in that the configuration.

And, the non-woven fabric for the main sole according to another preferred embodiment of the present invention, the upper layer non-woven fabric layer to form a sole contact surface continuous to the upper side of the activated carbon urethane foam layer; characterized in that it further comprises.

On the other hand, the functional insole made of a non-woven fabric for the main sole in accordance with another preferred embodiment of the present invention and the bottom of the sole non-woven layer of the foot shape that can be reached; A hemp nonwoven layer composed of 10 to 20% by weight of polypropylene fiber, 20 to 30% by weight of polyester fiber and 50 to 70% by weight of hemp fiber on the upper surface of the lower nonwoven fabric layer; Activated carbon urethane foam layer formed to mitigate the impact when walking or running using a material having an elastic force to the upper side of the non-woven fabric layer; And an upper layer non-woven fabric layer forming a continuous sole contact surface to the upper side of the activated carbon urethane foam layer, wherein the corresponding portions of the insole and the concave yongcheon located at the center of the foot are formed to have curved protrusions. It is characterized by preventing the propagation and odor of bacteria without feeling tired even when worn for a long time.

Hereinafter, a non-woven fabric for the main sole according to the present invention and a functional insole manufactured therefrom will be described.

1 is a cross-sectional view of the state in which the non-woven fabric for the main sole according to the present invention is applied to the insole.

Referring to Figure 1, the main sole nonwoven fabric 100 according to the present invention is a lower nonwoven fabric layer 110, hemp nonwoven fabric layer 120, activated carbon urethane foam layer 130 and upper nonwoven fabric layer 140 from below It is laminated | stacked and comprised.

Next, the hemp nonwoven layer 120 according to the present invention will be described.

The hemp nonwoven fabric layer 120 is a mixture of spun yarn and synthetic fibers, such as polypropylene and polyester, which is first dyed to the upper surface of the lower nonwoven fabric layer 110, and hemp fibers in a predetermined ratio by using a needle punching machine A compressed breathable hemp nonwoven layer 120 is fabricated. That is, the hemp nonwoven layer 120 is blended with 10 to 20% by weight of polypropylene (Poly Proplene) fiber, 20 to 30% by weight of Polyester (Poly Ester) fiber and 50 to 70% by weight of Hemp fiber The nonwoven fabric layer 120 is configured to be included. When synthetic fibers and hemp fibers are used in this way, all the parts of the nonwoven fabric to be produced are evenly mixed and thus the efficacy of the nonwoven fabric can be maintained semipermanently.

Here, the higher the content of hemp fiber can be exhibited the effect of the hemp well, but if the content exceeds the maximum value, the flexibility and elasticity of the hemp fiber falls. In addition, when the nonwoven fabric is manufactured with the weight of the nonwoven fabric 50g / m 2 to 300g / m 2, the surface texture is smoothed and the performance is improved.

Meanwhile, according to another exemplary embodiment of the present invention, an activated carbon urethane foam layer 130 is further provided as an upper surface of the hemp nonwoven fabric layer 120.

The activated carbon urethane foam layer 30 is formed to relieve the impact when walking or running using a material having an elastic force to the upper side of the hemp non-woven fabric layer 120, the impact relaxation and cushioning, antibacterial function, breathability, etc. Required.

To this end, the activated carbon urethane foam layer 130 is a polyol and isocyanate which is a raw material of the polyurethane sponge, and foamed with activated carbon powder having an excellent anti-oxidation, dehumidification and deodorizing effect and foaming agent. Therefore, negative ions and far-infrared rays generated from activated carbon penetrate deeply into the occupant's body to stimulate parasympathetic nerves, thereby facilitating blood circulation in the human body and relieving fatigue. Here, if the particle size of the activated carbon powder is less than 500mesh or more than 800mesh, even foaming does not occur when foaming, so that the cost increases, in consideration of economical efficiency is preferably 500 ~ 800mesh, but is not necessarily limited thereto. The thickness of the activated carbon urethane foam layer 130 may be any thickness capable of absorbing shock.

On the other hand, according to another preferred embodiment of the present invention, it is preferable that the upper layer buried fabric layer 140 is further provided on the upper surface of the activated carbon urethane foam layer 130.

The upper nonwoven fabric layer 140 forms a continuous sole contact surface to the upper side of the activated carbon urethane foam layer 130, which is required for breathability, hygroscopicity and wear strength as appropriate. For this purpose, it is composed of polyurethane (Poly Urethane) fibers, polyester (Poly Ester) fibers and Viscose Rayon (Viscose Rayon) fibers. Therefore, since the fabric is made of a soft fiber material, there is an advantage of preventing foot odor and preventing foot fatigue by preventing a temperature rise due to friction between the sole of the sole and the insole.

Hereinafter, the present invention will be described in more detail with reference to the following examples.
