Running shoes with enhanced deodorization and stain resistance

The present invention relates to a running shoe with enhanced deodorization and fouling resistance, and more particularly, a waterproof film in the form of a membrane provides smooth ventilation from the inside of the running shoe to the outside, but blocks water penetration from the outside to the inside while enhancing antibacterial properties. It protects the feet from various germs, and a small amount of scent is emitted from the sachet every time you walk, neutralizing and removing odors, suppressing the occurrence of odors, and increasing the cooling property to prevent sweating when wearing running shoes in summer, and to prevent contamination of the outer skin. Therefore, it relates to a running shoe with enhanced deodorization and stain resistance that improves convenience in shoe management.

Nowadays, as well-being culture is spreading and the need for diet is increasing, the number of people who do power walking is increasing day by day.

Power walking is a very fast walking exercise, and walking at a high speed, where the body movements are less efficient than running, can produce more exercise effects than when running.

Therefore, this power walking is a particularly combined exercise to maintain cardiopulmonary endurance and consume a large amount of calories.

Various sports shoes have been disclosed to be suitable for such power walking, and among them, running shoes are representative sports shoes to which the present invention belongs, and most of the sports shoes described in the present invention can be considered to mean running shoes.

Compared to light warnings, such running shoes must drain sweat well due to the nature of power walking, and are often worn before and after the summer, so it is necessary to give a feeling of refreshment when worn.

Particularly, during exercise, such as jogging, sweat smells inside the shoe, and a lot of external pollutants come in, and there is also a need to avoid this in terms of shoe management.

In addition, as they are mainly worn before and after the summer season, poor ventilation inside and outside the running shoes causes bacterial growth, which soon acts as a disadvantage that causes odor.

Recently, a lot of running shoes with good ventilation are on the market, but most of them only have holes in the upper fabric in the form of sparse or ventilation holes, so waterproofness is very weak. In this case, there is an inconvenience that must be completely dried.

1 is an exemplary photograph of running shoes with enhanced deodorization and contamination resistance according to the present invention.
2 is a partial cross-sectional view of the upper during running shoes of FIG. 1.
3 is an exemplary cross-sectional view showing the deodorizing structure of running shoes according to the present invention.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

As shown in FIG. 1, the running shoes with enhanced deodorization and contamination resistance according to the present invention have a sole 10 in contact with the sole, and a heel provided under the sole 10 and provided at a portion corresponding to the heel. 20) and, a foam upper part 30 attached to the upper surface of the sole 10 and surrounding the wearer's foot, and an upper 40 extending upwardly to the rear of the foam upper part 30 and surrounding the lower part of the ankle of the wearer. ).

At this time, the upper 40 is, as in the exemplary cross-sectional view of FIG. 2, between the inner skin 42 as a lining, the outer skin 46 forming the outer shape of the running shoes, and the inner skin 42 and the outer skin 46 It includes a middle pee 44 that is sewn in an interposed state to form a unity.

Here, the inner skin 42 is formed by weaving a composite processing work.

The composite processing work is a thread in which an adverb is wrapped around and fixed around an examination, and a fine loop is formed by protruding an adverb on the surface of the thread.

Therefore, it is soft and has excellent elasticity.

To this end, the screening uses 75D/36Fila nylon yarn, and the adverb uses 30D/18Fila polyester yarn.

In addition, the outer shell 46 is made of a fabric obtained by combining acrylic yarn and polyester yarn heat-resistant with chlorinated paraffin and TCPP (Tris 2-chloropropyl phosphate), and is sewn to integrally with the inner skin 42 and the middle skin 44. Is achieved.

For example, since it must be used in the form of a combination of two, an acrylic yarn and a polyester yarn are twisted to form a single fila, and then the fila is woven to make an outer sheath fabric.

Therefore, the outer shell 46 has a large number of voids, so that air permeability is good, elasticity is excellent, and heat resistance is excellent because it is heat-resistant.

In addition, since the outer shell 46 has a large number of voids, the middle skin 44 prevents water from permeating into the inner skin 42 because the outer skin 46 has a large number of voids, and a Gore-Tex membrane (Gore-Tex) to maintain breathability. Membrane) is used.

Gore-Tex Membrane was developed in 1973 and is now a known fiber. It is a special fiber that does not allow water to seep from the outside and sweat or water vapor from the inside.

When configured in this way, it is possible to implement running shoes that are resistant to heat, have excellent ventilation, and are waterproof while securing elasticity and tensile strength that protects the feet.

In particular, in the present invention, as in the example of Fig. 3 schematically illustrating an upper and a sole, a sachet 50 is further provided to suppress and purify the odor generated in running shoes.

The sachet 50 is disposed at the corner where the upper 40 and the sole 10 meet, is sewn and fixed to the inner side of the upper 40, and is protected by the circumference of the insole 60 and can be pressed indefinitely. It is structured to be.

More specifically, the sachet 50 is formed in an approximately'b' shape, which is composed of a sachet sewing part 52 that is sewn to the upper 40 and a ball attaching part 54 containing a deodorant component.

At this time, the sachet sewing part 52 and the ball receiving part 54 are both formed of a urethane material having excellent elasticity and elasticity and good resilience.

Here, the ball receiving portion 54 is molded in a form in which the deodorizing ball 56 is embedded, which can be molded in various ways such as injection molding and blow molding.

In particular, the ball receiving portion 54 is configured such that a number of unspecified fine needle holes are formed over the entire circumference so that the components gradually released from the deodorizing ball 56 can be sprayed over a very long period of time.

Of course, if the sachet 50 is crushed by being pressed against the foot, the amount of ejection will increase further. Nevertheless, since it is a very fine needle hole, the component released from the sachet 50 lasts a very long time.

In addition, the deodorant ball 56 does not contain a scent, but is formed into a spherical shape by combining special ingredients capable of expressing the scent, so the deodorizing function remains until the deodorizing ball 56 is worn out. There will be, so it would be okay to assume that the shoes are almost semi-permanent until discarded.

The deodorizing ball 56 is composed of a core 56a, a shell 56b surrounding the core 56a, and a protective shell 56c surrounding the shell 56b to maintain a spherical shape. And, a number of unspecified needle holes are formed around the deodorizing ball 56.

At this time, the core (56a) was mixed with 20% by weight of agar, 15% by weight of citric acid, 10% by weight of sugar, and the rest of water, boiled to 100°C, and cooled. Mix, but use the aqueous solution: scented powder mixed in a weight ratio of 9.8:0.2, cooled completely, and solidified.

Here, agar is added to solidify after gel formation, and sugar is added to make the agar firm and harden like jelly, but to make it gel evenly.

In addition, since citric acid is a type of tricarboxylic acid, it is mainly used to dissolve and remove basic substances such as lime in boiler pipes, yellow ammonia stones in urinals, and waste water in tiles. It is added to generate chlorine dioxide gas but to generate a stable and uniform amount, and the fragrance powder can be a natural fragrance component such as pepper powder and rosemary powder.

In addition, the shell (56b) after mixing 30% by weight of agar, 20% by weight of sodium chlorite, 20% by weight of sugar, and the remaining water, boiled to 100°C, and then the aqueous solution was mixed with water-soluble polyurethane 1 In the state of mixing at a weight ratio of :1, this mixture is blow-molded to surround the core 56a.

At this time, sodium chlorite is a crystalline powder and has excellent sterilization and deodorization properties due to its high oxidizing power.

Then, at the boundary where the core 56a and the shell 56b meet, citric acid and sodium chlorite react to generate chlorine dioxide gas.

For example, tatrium chlorite and citric acid may react as follows.

15 NaClO ₂ + 4 C ₆ H ₈ O ₇ → 12 ClO ₂ + 4 C ₆ H ₅ Na ₃ O ₇ + 3 NaCl + 6 H ₂ O

This chlorine dioxide gas realizes the functions of sterilization, deodorization, and deodorization, and at the same time, the scent ingredient is sprayed together, making the interior of the shoe in a comfortable state.

However, in order to maintain their shape and achieve long life, polyethylene resin is blow-molded once again to create a protective skin 56c that surrounds the shell 56b with a certain thickness, and then forms a number of unspecified needle holes. By doing this, the deodorizing ball 56 according to the present invention is completed.

Therefore, a greater amount of deodorant is released so that the contact between the two components increases while being pressed, so that the effect of suppressing the odor of shoes and emitting a fragrant odor can be further enhanced.

On the other hand, in the present invention, in addition to the configuration of such running shoes, the inner skin 42 may be immersed in a cooling reinforcing liquid to further enhance a refreshing feeling when worn.

At this time, the cooling enhancing liquid is glacial acetic acid (Glacial Acetic Acide) 13.5% by weight, erythritol 10% by weight, lithium bromide (LiBr) 10% by weight, isohexadecane 3.5% by weight, fullerene purezit powder 5% by weight, and phenyltrime A mixture of 3.5% by weight of oxysilane, 5% by weight of a water-soluble acrylic resin and the rest of water is mixed.

Here, glacial acetic acid has a certain point of 14.5°C or higher and freezes at room temperature to enhance cooling, and erythritol reacts with water with sugar alcohol to cause an endothermic reaction to take away heat from the surroundings to feel cooling. Lithium bromide It is used as addition because it has very high hygroscopicity and increases cooling property while attracting moisture around it.

In addition, isohexadecane has excellent solubility in solid content and enhances the binding function by increasing the dispersive binding force.

In addition, fullerene purezit powder should contain 60% or more of fullerene and use a 0.5㎛ particle size of a shungite powder.Sungite refers to a natural mineral mainly containing silicate and fullerene, and fullerene. is inde as the third allotrope of carbon for the other allotropes of carbon diamond and graphite carbon atoms are solids that are infinitely array hand, and by the finite molecular molecular formula is C _60, such a powerful antioxidant as the most powerful of the antioxidants of the earth It is added to suppress the activity or proliferation of bacteria such as fungi on the construction surface.

In addition, phenyltrimethoxysilane has hydrophobic properties and is added to obtain moisture resistance as well as water repellency, and the water-soluble acrylic resin is added to maintain excellent binding properties and increase adhesion during impregnation.

In order to check whether there is a cooling characteristic, that is, a cooling sensation characteristic, the following experiment was performed by comparing the case of using the inner skin 42 immersed in the cooling reinforcing liquid and the case not using it.

Two samples were put into the humidity chamber maintained at 10°C, and hot air was applied to keep the inside of the humidity chamber at 27°C for 10 minutes. Then, an infrared thermometer was irradiated on the surfaces of the two samples to check whether there was heat loss.

As a result of the test, after 1 hour, the surface temperature of the endothelium immersed in the cooling reinforcing solution was 19.5°C, and the temperature of the non-immersed endothelium was 22.4°C. Through this, it was confirmed that the cooling property was strengthened as the temperature rapidly decreased after a certain period of time.

In addition, in the present invention, before weaving the nylon yarn and polyester yarn constituting the inner skin 42, it is first immersed in a surface treatment solution to be processed while the surface is treated, thereby not only having flexibility, but also removing residual oil components. And, it is particularly preferable to have antistatic properties.

To this end, the surface treatment liquid is methylsiliconate 5.5% by weight, methyl salicylate 5% by weight, titanium oxide 2.5% by weight, sulforaphane (C ₆ H ₁₁ NOS ₂ ) 3.0 weight, and glyceryl monostearate 3.5 It consists of weight %, acetum 6 weight% and the rest of methyl alcohol.

At this time, the methyl silicate provides a strong water repellency and also secures an antifouling function to keep the surface smooth so as not to be contaminated.

In addition, Methyl Salicylate is a colorless liquid, has a specific gravity of 1.18, a boiling point of 223°C, and a melting point of -9°C, which is added to contribute to flavor and yarn softening.

In addition, titanium oxide maintains an ultraviolet shielding function, and the sulforaphane is added to enhance resistance to discoloration by increasing resistance to ultraviolet rays.

In addition, glyceryl monostearate is usually used as a food emulsifier, but in the present invention, it is added to contribute to antistatic properties and yarn softening according to the surfactant function.

In addition, Acetum is a vegetable antistatic agent, which is added to protect the yarn by its antistatic properties.

In addition, methyl alcohol is added to increase the flexibility and weather resistance of the yarn by removing oil remaining on the yarn surface.

After immersing the yarn in such a surface treatment solution for 2-3 hours, it is sufficient to dry it in a low-temperature drying room maintained at 25-30°C and then weaving.

Further, in the present invention, in order to increase the contamination resistance, the yarn for making the outer shell 46, that is, the acrylic yarn and the polyester yarn, may be immersed in a fouling-resistant solution before weaving and dried sufficiently before weaving.

In this case, the antifouling solution is petroleum sulfonate 4% by weight, liquid silicone 10% by weight, polysorbate 80 3% by weight, saponin 5% by weight, dichlorodimethylsilane 15% by weight and the rest of polyester It is composed of resin.

At this time, petroleum sulfonate is added to enhance the antifouling function by preventing discoloration and increasing surface activity.

In addition, liquid silicone is added to enhance the stain resistance by increasing the moldability of the outer shell and increasing the surface activity to lower the slip resistance.

In addition, Polysorbate 80 is a nonionic surfactant and emulsifier derived from sorbitol, which also includes a crosslinking function, prevents deformation of the product, increases durability, and induces it to achieve a longer life.

In addition, although the saponin contains both hydrophilic and hydrophobic moieties, it provides moisture-proof properties by promoting a fouling-resistant function through a surfactant action.

In addition, the dichlorodimethylsilane is a material showing very strong hydrophobicity because it has two chlorine atoms, which have the second largest electronegativity after fluorine (F), and has excellent moisture-proof properties and excellent stain resistance.

In addition, the polyester resin is added to increase the binding properties between the components while enhancing the bonding and occlusality with the outer shell.

When configured in this way, it is possible to increase the contamination resistance of the outer skin, which increases the convenience of running shoes management.
