The present invention relates to a fiber optic fabric and shoes comprised of a such a fabric, and more particularly, to a pattern formation part having a fiber optic pattern on the surface, a fabric having the same, and shoes or footwear having the upper.
In general, a shoe includes a sole which is a part making contact with the floor or ground, and an upper above the sole which is coupled with the sole to cover the foot of the wearer.
By way of enhancing the convenience and efficiency in shoe manufacture, the shoe upper may be woven in one piece. More details on this type of shoe upper, which has already been filed by the same applicant of this invention and granted a patent can be found in Korean Patent Registration No. 10-1437472, titled “Shoe uppers, manufacturing method thereof, and shoes using the same.”
There are also shoes having a light emitting function in the art. One example of those shoes is presented in Korean Utility Model Registration No. 29-0278136, titled “Light-up shoes.”
However, these conventional shoe uppers and light up shoes have limited functions, such as, flashing lights or lighting surroundings, and contain LEDs simply attached onto the shoe uppers. The manufacture of such shoe uppers takes much time, lowering the manufacturing efficiency, and it is likely that the LEDs are easily detached from the shoe uppers. Besides, the LEDs attached onto the shoe uppers is not aesthetically attractive.

The main body part is comprised of a fabric made by interweaving first and second main body part warp yarns with first main body part weft yarns. As the first and second warp yarns of the pattern formation part are continuously involved in the weaving process of making the main body part, they constitute the first and second main body part warp yarns, respectively.
Additionally, or alternatively, all the first war yarns, the second warp yarns, the first main body part warp yarns, and the second main body warp yarns can be transparent that transmit at least part of light.
Additionally, or alternatively, the pattern formation part further comprises second weft yarns which are alternately arranged with the first weft yarns next to each other, in which the first and second weft yarns are interwoven with the first and second warp yarns.

In another aspect of the present invention, there is provided an upper comprising the pattern formation part according to any of the embodiments of the present invention.
In another aspect of the present invention, there is provided a shoe comprising the upper according to any of the embodiments of the present invention.
Moreover, the pattern formation part and the fabric comprising the same according to an aspect of the present invention are formed by integrally weaving a fiber optic pattern on the surface, instead of forming a separate pattern, such that a luminous effect can be emphasized exclusively and selectively on the pattern (logo) part. This not only improves the manufacturing efficiency of the shoe upper and shoes including the same and ensures that the pattern part is not easily detached from the upper, it also creates an aesthetically attractive appearance through the exclusive and selective luminous effect from the pattern (logo) part.
With reference to the drawings, an exemplary embodiment of a shop upper with an illuminating logo according to the present invention and a shoe including the same will be described in detail below.
Woven fabrics can be categorized into single-weave fabrics, double-weave fabrics, pile-weave fabrics, and doup-weave fabrics. They can also be categorized into plain-weave fabrics and leno-weave fabrics. However, the present invention is not limited to thereto.
In plain weave fabric, as shown in A-1 and A-2 of
In general, a fabric is made by passing the warp yarn through a heddle eye in the center of the heddle, following by taking the heddle up and down to let the warp yarn going up and down accordingly and form a hole between neighboring warp yarns, and then inserting the weft yarn into the hole. Depending on the type of a machine used for making holes, fabrics can be classified into dobby fabrics suitable for weaving simple or small geometric patterns and jacquard fabrics suitable for complicated or large geometric patterns.
The dobby fabric for small geometric patterns can be woven using a dobby machine which has 20 to 40 (depending on a desired pattern) heddles fixed onto a harness frame. As the heddles move up and down together, slots are created between the warp yarns under controlled up-and-down movements of the heddles. The weft yarns are then inserted into those slots.
The jacquard fabric can be woven on a jacquard loom, in which each warp yarn is adjusted with an individual heddle, and heddles are not fixed onto a harness frame. As the heddles move up and down, slots are created between the warp yarns under controlled up-and-down movements of the heddles. The weft yarns are then inserted into those slots. Korean Paten Registration No. 10-1419495 described one of conventional jacquard looms.
The following will describe the present invention in detail with reference to the drawings.
One aspect of the present invention provides a pattern formation part having a fiber optic pattern on the surface.
Referring to
As described above, the pattern formation part in this embodiment can include the first warp yarns and the second warp yarns.
When the pattern formation part of the present invention is a plain-weave fabric, the first warp yarns of the pattern formation part may look like those 201, 211 in A-1 and A-2 of
Likewise, when the pattern formation part of the present invention is a plan-weave fabric, the second warp yarns of the pattern formation part may look like those 202, 212 in A-1 and A-2 of
At least one of the first and second warp yarns can be transparent, such that at least part of light can be transmitted. To this end, the transparent warp yarns should be made of a material that is either transparent or translucent at the least. However, the present invention is not limited to particular materials.
The pattern formation part in this embodiment can also include first weft yarns, as mentioned above.
Referring back to
The first weft yarns of the pattern formation part of the present invention may be fiber optic weft yarns.
The optical fiber is a transparent thread-like fiber made of glass or plastic materials having a diameter of several hundred to several thousand micrometers (μm) (1 μm equals to 1/1000 mm), for example, 125 to 3000 μm. Usually, it has a double-walled cylinder structure including a core with a high refractive index in the center and a cladding portion with a low refractive index that encompasses the core. Thus, the light passing through the core in the center can be totally reflected, which in turn minimize light loss and enables light emission to a longer distance. Depending on the application, two different types of optical fiber may be used, which include end lighting fibers that emit the light only from the fiber end, and side lighting fibers that constantly emit the light from the side of the fiber. Any of the end lighting fibers and the side lighting fibers may be applicable to the first fiber optic weft yarns of the pattern formation part. For example, the pattern formation part of the present invention includes the optical fiber as the first weft yarns, and the ends of the optical fiber can be tied to a bundle and connected to a light source unit. Here, the optical fiber bundle may be inserted into an opaque tube that does not transmit the light. It has been confirmed that both the end lighting fibers and the side lighting fibers are suitable for the first weft yarns of the pattern formation part in the present invention.
The pattern formation part may be a fabric formed by interweaving the first and second warp yarns with the first weft yarns together. This means that the first warp yarns 201, 211 and the second warp yarns 202, 212 may be placed one after the other in a row and the first weft yarns 251, 261 cross at right angles to the warp yarns, going alternately over-and-under to form a plain-weave fabric, as shown in A-1 and A-2 in
As discussed earlier, the pattern formation part of the present invention may be a fabric having a fiber optic pattern on the surface that is obtained by an optical fiber for the first weft yarns of the pattern formation part. Therefore, upon receiving the light from the light source unit (not shown), the first fiber optic weft yarns will be lighted in their corresponding areas to form an intended illuminating pattern.
Additionally, if either the first warp yarns or the second warp yarns may be opaque, not allowing the light to pass through, the first weft yarns always go over those opaque yarns during weaving. To explain further with reference to
When both the first warp yarns and the second warp yarns are transparent, the first weft yarns of the pattern formation part of the present invention can go over or under the first warp yarns and/or the second warp yarns. In this case, since both the first warp yarns and the second warp yarns are transparent, even if the first weft yarns would go under the warp yarns, at least part of light emitted from the first weft yarns will transmit through the warp yarns. As a result, a pattern by the first fiber optic weft yarns can be formed on the surface of the pattern formation part.
On the other hand, when either the first warp yarns or the second warp yarns are opaque, not allowing the light to pass through, the first weft yarns always go over those opaque warp yarns during weaving. Referring again to A-2 in
Referring now to B-1 in
Another exemplary embodiment in an aspect of the present invention provides a pattern formation part in which both the first warp yarns and the second warp yarns are transparent that transmit at least part of light. If this the case, the weft yarns may go either over or under the warp yarns during the weaving process of making the pattern formation part. Now that the weft yarns are only taken into consideration for patterning without worrying about the direction the yarns need to go, the manufacturing efficiency of the pattern formation part can be maximized. Any material that transmits at least part of light can be used for the transparent warp yarns in the present invention.
Another exemplary embodiment in an aspect of the present invention provides a pattern formation part that further includes second weft yarns.
In particular, the pattern formation part further includes second weft yarns that are arranged alternately with the first weft yarns in a row. That is, the first weft yarns and the second weft yarns are placed one after the other consecutively in a row, as seen on the same plane of the pattern formation part.
Also, the second weft yarns arranged next to the first weft yarns may be woven with the first and second warp yarns. In particular, during weaving, the first and second weft yarns run through the same slot together or different slots separately, which are formed by the first and second warp yarns (this is relevant to a plain weave as well as a leno weave).
When the first warp yarns or the second warp yarns are opaque, not allowing the light to pass through, the second weft yarns always go over the opaque warp yarns during weaving.
To elaborate the exemplary embodiment of the pattern formation part further including the second weft yarns according to the present invention, the first and second weft yarns run through the same slot together that are formed by the first and second warp yarns (this is relevant to a plain weave as well as a leno weave) during weaving, which also occurs whether or not the weft yarns are comprised of first and second weft yarns. For example, as shown in A-1, A-2, B-1 and B-2 of
In another exemplary embodiment of the pattern formation part further including the second weft yarns according to the present invention, the first and second weft yarns run through different slots separately that are formed by the first and second warp yarns (this is relevant to a plain weave as well as a leno weave) during weaving. In particular, referring to the plain weave as shown in A-1 and A-2 of
In the present invention, the second weft yarns may be pattern formation weft yarns of a certain color. Thus, when the first fiber optic weft yarns are not illuminated, there will still be a colored pattern formed by the second weft yarns.
Another exemplary embodiment in an aspect of the present invention provides a pattern formation part further including back-side weft yarns.
In particular, the back-side weft yarns of the pattern formation part are arranged at the back of the first weft yarns to prevent backward emission of the light from the first weft yarns. The back-side weft yarns can be woven with at least one of the warp yarns. As described earlier, the first weft yarns are made of optical fibers such that light emitted from the optical fibers can be directed not only toward the surface of a fabric of the pattern formation part but also toward the back side, possibly causing light loss. Therefore, having the back-side weft yarns at the back of the first weft yarns according to the present invention can reduce the light loss by preventing backward emission of the light from the optical fibers, and allow the formation of a pattern with high-efficiency optical fibers.
As mentioned above, at least one of the warp yarns can be woven together with the back-side weft yarns.
In particular, according to the exemplary embodiment, the first weft yarn is woven with at least one of the warp yarns that are also involved in the weaving process with the back-side weft yarns. Here, the number of warp yarns involved in weaving with the first weft yarns may be equal to or smaller than the number of warp yarns involved in the weaving process with the back-side weft yarns. In this way of weaving, the first weft yarns may be placed in front of (over) the back-side weft yarns during weaving with the warp yarns. Alternatively, if the back-side weft yarns and the first weft yarns are stacked together, the first weft yarns may also be placed in front of (over) the back-side weft yarns during weaving with the warp yarns. In this case, both the first weft yarns and the back-side weft yarns are involved in the weaving process of making the pattern formation part.
In another exemplary embodiment, the back-side weft yarns may be woven with at least one of the warp yarns involved in the weaving process with the first weft yarns. In this embodiment, the back-side weft yarns are arranged at the back of the first weft yarns and woven with the corresponding warp yarns. Here, the back-side weft yarn together with the first weft yarn may be woven with the warp yarns, or the back-side weft yarn may be woven with at least one of the warp yarns, separately from the first weft yarn. In the latter case, the back-side weft yarn may be woven with at least one of the warp yarns during the weaving process of the first weft yarns and the corresponding warp yarns, getting involved in the weaving process of making the pattern formation part. Then it may be withdrawn from the weaving process by not being woven with any of the warp yarns but taken out to the back side of the pattern formation part. Later, it comes back to the weaving process by being woven with at least one of the warp yarns for weaving the pattern formation part. That is to say, the back-side weft yarn may be sparsely woven with at least one of the warp yarns that are woven with the first weft yarn.
Another aspect of the present invention provides a fiber optic fabric which includes a pattern formation part having a fiber optic pattern on the surface, and a main body part having an optical fiber-free surface.

Going back to
The first warp yarns 311 and the second warp yarns 312 of the pattern formation part 310 included in the fiber optic fabric of the present invention are continued across the main body part 320, forming first main body part warp yarns 321′ and second main body part warp yarns 322′. In other words, referring to
If the main body part 320 is placed on the right and left sides of the pattern formation part 310, an interface is created between the main body part 320 and the pattern formation part 310. This will be described below.
Additionally, or alternatively, in the fiber optic fabric of the present invention, each of the first and second warp yarns of the pattern formation part and each of the first and second main body part warp yarns of the main body part can be transparent that transmit at least part of light. When both the first and second warp yarns of the pattern formation part are transparent, allowing at least part light to pass through, the weft yarns may go either over or under the warp yarns during the weaving process of making the pattern formation part. Now that the weft yarns are only taken into consideration for patterning without worrying about the direction the yarns need to go, the manufacturing efficiency of the pattern formation part can be maximized. Likewise, when both the first and second main body part warp yarns of the main body part are transparent, allowing at least part of light to pass through, the weft yarns may go either over or under the warp yarns during the weaving process of making the pattern formation part. Now that the weft yarns are only taken into consideration for patterning in particular colors as desired without worrying about the direction the yarns need to go, the manufacturing efficiency of the main body part can be maximized. Additionally, or alternatively, given that all of the warp yarns are transparent that can transmit at least part of light as mentioned above, the same type of transparent warp yarns may be employed for the first and second warp yarns of the pattern formation part and for the first and second main body part warp yarns of the main body part, such that the main body part and the pattern formation part can be manufactured at a higher efficiency. Any material that transmits at least part of light can be used for the transparent warp yarns in the present invention.

This main body part further including the second main body part weft yarns is schematically shown in
As can be seen from
Additionally, or alternatively, in the fiber optic fabric in another aspect of the present invention, the first main body part weft yarns may be involved in the weaving process of making the main body part, and then withdrawn from the weaving process of making the pattern formation part by being taken out to the back side of the fabric from an interface between the fabric and the pattern formation part.
