MULTI-FUNCTION HEALTH CARE SELF-CLEANING SHOE MATERIAL

Description

FIELD OF THE INVENTION

The present invention relates to a multi-function health care self-cleaning shoe material, which can be used for shoe vamp, shoe pad, or shoe sole.

BACKGROUND OF THE INVENTION

Shoes are necessaries for human daily life and are used for most of the time. Wearing shoes for such a long time may significantly influence human health. Specifically, the air permeability and antibacterial ability for shoes are quite important. The shoe sole, shoe vamp, and shoe pad are the components of a conventional shoe. Once these components are designed to have air permeability and antibacterial ability, it would increase the shoes' function in ensuring the health of the shoe wearers. To the inventor's knowledge, the conventional shoe material with antibacterial ability is only used for shoe pad, but not for shoe vamp and shoe sole. The conventional shoe pad with antibacterial ability is manufactured from nonwoven cloth (fabric) and an antibacterial material is added into the nonwoven cloth, making insufficient air permeability, uncomfortable to wear, unable to reuse in a long term through simple cleaning process, bad durability, and unable to produce effective vibration in the shoe pad such that the functional material thereof cannot exhibit its effect in the foot environment.

SUMMARY OF THE INVENTION

The first objective of the present invention is to provide a multi-function health care self-cleaning shoe material with better air permeability and air cushion structure. Further, through the friction, vibration, air flow, temperature difference between the foot and the fibers, nano functional particles react to achieve the effects of sufficiently effective bacteria-killing, anti-bacteria, mildewproof, anti-mite, negative ion, far-infrared ray, flameproof, antistatic, anti-electromagnetic wave, deodorization, TVOCs elimination, and so on.

The second objective of the present invention is to provide a multi-function health care self-cleaning shoe material with everlasting fragrance for preserving human health.

The third objective of the present invention is to provide a manufacturing method for a multi-function health care self-cleaning shoe material.

In order to achieve the above objectives, the present invention introduces the following scheme.

The present invention has the following advantageous effect:

- 1. The multi-function health care self-cleaning shoe material of the present invention uses polypropylene or polyethylene fragments mixed with functional particles (for example, tourmaline, nano silver particle, ferment, microcapsule, and so on), mixing, fusing, and spinning to produce fibers. The fibers are used to produce a web body and then designed to produce a shoe material, for example, shoe pad, shoe sole, or shoe vamp with better air permeability and air cushion structure. Through the friction, vibration, air flow, temperature difference between the foot and the fibers, nano functional particles react to achieve the effects of sufficiently effective bacterial killing, anti-bacteria, mildewproof, anti-mite, negative ion, far-infrared ray, flameproof, antistatic, anti-electromagnetic wave, deodorization, TVOCs elimination, pollutant PMx elimination, and so on.
- 2. The multi-function health care self-cleaning shoe material of the present invention uses polypropylene or polyethylene fragments mixed with functional particles (for example, tourmaline, nano silver particle, ferment, microcapsule, and so on), mixing, fusing, and spinning to produce fibers, and uses TPE to control the release of micro capsules and enhance the elasticity and comfortability. Micro capsules containing natural essential oil are included in the fibers to make the shoe material with everlasting fragrance for preserving human health.

DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

The following exemplary examples will be described in detail with the appended drawings in order to make the objectives and means of the present invention more clearly understood.

I. Basic Structure of the Shoe Material of the Present Invention

Referring to FIG. 1, a main objective of the present invention is to design a multi-function health care self-cleaning shoe material. The shoe material can be shoe vamp, shoe pad or shoe sole. The basic structure includes a shoe material main body 10 having a peripheral contour area 11 and an inner area 12 and a sheet-form web body 120 provided in the inner area 12 of the shoe material main body 10. The web body 120 is fixed on the peripheral contour area 11. The web body 120 is a web-form fabric having plural fibers 13 in warp direction and plural fibers 13 in weft direction, and there are a plurality of functional particles 130 (referring to FIG. 4) in the fibers. The fiber is between 50 and 10000 Denier. The fiber can be made of polypropylene, polyethylene, nylon, tetolon, and so on, depending on the required characteristics; for example, polypropylene is acid proof and alkali proof.

Referring to FIGS. 1 and 7, if the shoe material is used for shoe pad 100 or shoe sole 102, in order to enhance the strength of the shoe pad 100 or shoe sole 102, a plurality of reinforcements 15 may be provided on certain locations of the shoe pad 100 or the shoe sole 102 to enhance the support and elastic abilities of the shoe pad 100 or the shoe sole 102. The reinforcements 15 may be made of polyurethane (PU), thermoplastic elastomer (TPE) or EPA for good durability. The reinforcements 15 may be formed on the shoe pad 100 or the shoe sole 102 by directly pouring PU, TPE, or EPA to the shoe pad 100 or the shoe sole 102, followed by a drying process.

The shoe material main body 10 of the present invention may be a shoe sole 102 (FIG. 7) or shoe pad 100 (FIGS. 1 and 2), or a shoe vamp 101 (FIG. 3). The shoe pad 100 is placed in the shoe 20 to separate the shoe sole and the human foot so as to generate air cushion effect and prevent the shoe sole from being rapidly worn away. When the shoe material main body 10 is used for shoe pad 100, the shoe pad 100 includes the peripheral contour area 11, the inner area 12 and the web body 120, wherein the peripheral contour area 11 of the shoe pad 100 may be a glue layer used to fix the ends of the fibers 13. Further, the peripheral contour area 11 of the shoe pad 100 may also be a bonding line 110 formed by fusing the fibers 13 of the web body 120 together with the ends of the fiber 13 being fixed by the bonding line 110.

Furthermore, referring to FIGS. 5 and 7, in the case that the shoe material main body 10 is used for shoe sole 102 or shoe pad 100, it may include a plurality of layers of the web body 120 to increase the thickness of the inner area 12 and in turn to enhance air permeability and air cushion effect. Each layer of the web body 120 includes plural fibers 13 in warp direction and plural fibers 13 in weft direction. The peripheral contour area 11 of each layer of the web body 120 is a bonding line 110 formed by fusing fibers 13 themselves together with the ends of the fibers 13 being fixed by the bonding line 110. As shown in FIG. 5, according to a preferred embodiment of the present invention, the inner area 12 includes at least one dot-shaped or line segment-shaped bonding portion 121. The bonding portion 121 is formed by bonding the fibers 13 of the web body 120 themselves together and can enhance the robustness of the web body 120 when stacking.

The cloth layer 14 overlies the web body 120 of the shoe pad 100, and the friction coefficient of the cloth layer 14 is higher than the friction coefficient of the web body 120. In a preferred embodiment, the cloth layer 14 and the web body 120 of the shoe pad 100 are bonded together by at least one dot-shaped or line segment-shaped bonding portion 140 so as to enhance the robustness between the web body 120 and the cloth layer 14.

Referring to FIG. 7, in the case that the shoe material main body 10 is used for shoe sole 102, an arc-shaped belt 103 is connected to the shoe sole 102 for human's foot to wear in so as to form a slipper structure.

Referring to FIGS. 8 to 10, the web body 120 of the shoe material main body is weaved to have an array of a plurality of three dimensional honeycomb structure 121. Each honeycomb structure 121 is formed by plural warp fibers 13 arranged along a first arc face 122 and plural weft fibers 13 arranged along a second arc face 123. The first arc face 122 intersects the second arc face 123. With the three dimensional honeycomb structure 121, high structure strength and air cushion effects of the shoe material are achieved.

In a preferred embodiment, the functional particles may be submicron tourmaline to make the shoe material have the effects of generating negative ion, far-infrared ray, self-clean, deodorization, antistatic, anti-electromagnetic wave, and so on, and one of the following micro particle healthy factors can be added: nano bamboo carbon, zinc oxide, cupric oxide, ferric oxide, silica, tungsten oxide, manganese oxide, cobalt oxide, nickel oxide.

In another preferred embodiment, the functional particles may be nano silver particle to make the shoe material have the effects of bacterial killing, anti-bacteria, mildewproof, anti-mite, and so on, and one of the following healthy micro particle factors for killing bacterial, anti-bacteria, and mildewproof can be added: chitin, ferment, or nano noble metal, e.g., copper, zinc, aurum, platinum, palladium, and niobium.

In another preferred embodiment, the functional particles may be microcapsule provided with an internal storage space for storing various functional materials. The microcapsule is made of chitosan, thermoplastic elastomer, and so on. The functional material may be natural essential oil selected from the group consisting of lavender, lemon, hinoki, rosemary, eucalyptus, tea tree, sandalwood, bergamot, pine, jasmine, rose, chamomile, Ylang Ylang, basil, geranium, niaouli, cardamom, musk, myrrh, cinnamon, fennel, frankincense, citrus, peppermint, cedarwood, patchouli, palmarosa, clove, grapefruit, benzoin, ginger, citronella, and marjoram.

IV. Conclusion

Therefore, with the above structure design, the present invention indeed has the following advantages and features:

- 1. The fiber of the shoe material of the present invention is mixed with functional particles so as to achieve the health care effects of bacterial killing, anti-bacteria, mildewproof, anti-mite, negative ion, far-infrared ray, flameproof, antistatic, anti-electromagnetic wave, deodorization, elimination of pollutant, e.g., TVOCs, PMx and so on, etc.
- 2. The shoe material of the present invention, when used as a shoe pad, has multi-layer structure, which makes the fiber have both mechanical property and better elasticity. When a fluid passes through the shoe material, vibration can be generated, thus activating the functional micro particles in the fibers to react vigorously to achieve effective health care function and also properly relax the foot.
- 3. The shoe material of the present invention, when used as shoe pad, is woven by fibers. It has better air ventilation and can be washed by water. Sanitation and health care can be ensured.
- 4. The shoe material of the present invention adds functional particles (such as submicron tourmaline). The mechanical strength of the shoe material thus produced is only slightly decreased.
- 5. The shoe material of the present invention adds functional particles (such as submicron tourmaline). The washing fastness experiment shows that the shoe material thus produced still holds predetermined functions.
- 6. The submicron tourmaline particle can efficiently enhance performance under electrostatic adhesion theory since the tourmaline is of negative electricity. The shoe material has better elasticity and friction. Since the water decomposes to be negative ions (H₃O²⁻) due to the special effect of thermal electricity and piezoelectricity, vibration frequency increases, friction force grows, a large amount of negative ions is released in dynamic model, so as to satisfy the standard requirement (1000-2000 ion/cc) for human health.
- 7. The present invention has microcapsule with essential oil. In order to avoid the essential oil from evaporating too soon, the essential oil is released at near fixed amount, so as to enhance the duration.
- 8. The shoe material of the present invention has predetermined antibacterial effect when nano silver particles are added therein.
- 9. The shoe material of the present invention is also flameproof. The safety of flameproof is secured.
