1. Field of the Invention
This invention generally relates to a stereoscopic weft knitted fabric for vamp. More particularly, this invention relates to a knitted fabric for vamp having stereoscopic patterns.
2. Description of the Prior Art
In general, a shoe includes a vamp, a tongue, and a sole. Besides covering the foot to prevent the foot from an injury caused by the friction between the foot and an object, the vamp also serves the purposes of helping the user to distinguish one's own shoes and enhancing the aesthetics of the shoe.
As to the function of covering the foot to prevent the foot from an injury caused by the friction between the foot and an object, the conventional approach is to increase the thickness of the vamp, which increases the weight of the shoes and is unfavorable to the lightening of the shoes. Another approach is to use a foamed material as the vamp. However, the foamed material is unfavorable for eliminating moisture and heat due to its poor air permeability. The problem with eliminating moisture and heat would be solved by using a knitted fabric having both stereoscopic patterns and better air permeability as the vamp.
As to the function of helping the user to distinguish one's own shoes and enhancing the aesthetics of the shoe, the use of stereoscopic knitted fabric as vamp can significantly increase the design flexibility of the outward appearance of the shoe, and further enhance the distinguishability and aesthetics of the shoes.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide a stereoscopic weft knitted fabric for vamp.
The stereoscopic weft knitted fabric for vamp includes a puffy layer and a knit layer. The puffy layer is composed of a first wire which is wider than 900 Denier. The knit layer includes a first knit layer and a second knit layer disposed respectively on the opposite sides of the puffy layer. A flat area and a stereoscopic area are respectively defined on the knit layer, wherein the flat area surrounds the stereoscopic area.
In one embodiment of the present invention, the puffy layer is composed of the first wire disposed as multiple stacks.
In one embodiment of the present invention, the puffy layer is composed of the first wire disposed as single layer.
In one embodiment of the present invention, wherein the stereoscopic weft knitted fabric for vamp is weaved by a knitting machine having the number of needle in the range between 12 and 14.
In one embodiment of the present invention, the first knit layer and the second knit layer pass respectively through the puffy layer and interweave in the flat area to limit the gap between the first knit layer and the second knit layer in the flat area.
In one embodiment of the present invention, at least one of the first knit layer and the second knit layer includes thermoplastic material, wherein the first knit layer and the second knit layer approach each other in the flat area and are pressed against the puffy layer to be thermo-molded.
In one embodiment of the present invention, the first wire includes insulated conducting wires.
In one embodiment of the present invention, the first wire includes optical fibers.
In one embodiment of the present invention, the first knit layer of the knit layer protrudes outward in the stereoscopic area, wherein the second knit layer stays flat.
In one embodiment of the present invention, the stereoscopic weft knitted fabric for vamp includes a first knit layer, a puffy layer, and a second knit layer. The puffy layer is disposed on one side of the first knit layer, wherein the puffy layer is composed of a first wire having linear density larger than 900 Denier. The second knit layer is disposed on the other side of the puffy layer with respect to the first knit layer. The first knit layer and the second knit layer surround and grip together the puffy layer to make respectively the gripped portion and the ungripped portion of the puffy layer flat and puffy.
In one embodiment of the present invention, the stereoscopic weft knitted fabric for vamp is weaved by a knitting machine having the number of needle in the range between 12 and 14.
In one embodiment of the present invention, the first knit layer and the second knit layer pass respectively through the puffy layer and interweave in the gripped portion of the puffy layer to limit the gap between the first knit layer and the second knit layer in the gripped portion of the puffy layer.
In one embodiment of the present invention, at least one of the first knit layer and the second knit layer includes thermoplastic material, wherein the first knit layer and the second knit layer approach each other in the gripped portion of the puffy layer and are pressed against the puffy layer to be thermo-molded.
In one embodiment of the present invention, the first knit layer of the knit layer protrudes outward in the ungripped portion of the puffy layer, wherein the second knit layer stays flat.
As shown in the embodiment in
Taking a different point of view, as the embodiment shown in
Since the puffy layer 100 is composed of a plurality of first wires 110 having linear density larger than 900 Denier, the puffy layer 100 has a high degree of puffiness in the stereoscopic area 600. More particularly, the first wires 110 of the puffy layer 100 can be seen as the frame in the stereoscopic area 600. Since the linear density of the first wires 110 is larger than 900 Denier, i.e. having wider diameter, the first wires 110 occupy more space such that they give a high degree of puffiness to the puffy layer 100.
As shown in the embodiment in
As shown in the embodiment in
As shown in the embodiment in
Moreover, localized puffy effect can be produced in the stereoscopic weft knitted fabric 900 of the present invention. As shown in the embodiment in
The first knit layer 310 and the second knit layer 320 can be interwoven via various methods. As shown in the embodiment in
As shown in another interweaving method used in the embodiment in
In different embodiments, the forming of the gap between the first knit layer and the second knit layer is not limited to interweaving. For example, at least one of the first knit layer and the second knit layer may include thermoplastic material, wherein the first knit layer and the second knit layer approach each other in the flat area and are pressed against the puffy layer to be thermo-molded. More particularly, the first knit layer and the second knit layer that are pressed against the puffy layer are capable of being melted to pass through the puffy layer and stick with each other after cooling, such that the puffy layer is secured therebetween.
In the embodiment shown in
Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
