FIG. 5 is a schematic view showing an embodiment which protrudes outward on one side of the stereoscopic weft knitted fabric in the stereoscopic area. - As shown in the embodiment in
FIG. 1A , the stereoscopic weft knittedfabric 900 includes apuffy layer 100 and aknit layer 300. Thepuffy layer 100 is composed of a plurality offirst wire 110 which is wider, in linear density, than 900 Denier (a unit of measure for the linear mass density of fibers, which is the mass in grams per 9000 meters of the fiber). The first wire can be any functional fibers and yarns or heterogeneous materials of plant fibers, animal fibers, artificial fibers, metallic fibers, or objects having the appearance or shapes of yarns such as insulated conducting wires and optical fibers. Theknit layer 300 includes afirst knit layer 310 and asecond knit layer 320 disposed respectively on the opposite sides of thepuffy layer 100. Aflat area 400 and astereoscopic area 600 are respectively defined on theknit layer 300, wherein theflat area 400 surrounds thestereoscopic area 600. In this embodiment, the gap D400 between thefirst knit layer 310 and thesecond knit layer 320 in theflat area 400 is smaller than the gap D600 between thefirst knit layer 310 and thesecond knit layer 320 in thestereoscopic area 600. - Taking a different point of view, as the embodiment shown in
FIG. 1A , the stereoscopic weft knittedfabric 900 includes afirst knit 310, apuffy layer 100, and asecond knit layer 320. Thepuffy layer 100 is disposed on one side of thefirst knit 310, wherein thepuffy layer 100 is composed of a plurality offirst wire 110 which is wider than 900 Denier. Thesecond knit layer 320 is disposed on the other side of thepuffy layer 100 with respect to thefirst knit layer 310. Thefirst knit layer 310 and thesecond knit layer 320 surround and grip together thepuffy layer 100 to make respectively the gripped portion and the ungripped portion of thepuffy layer 100 flat and puffy, wherein the gripped flat portion and the ungripped puffy portion correspond respectively to the flat area and the stereoscopic area. - Since the
puffy layer 100 is composed of a plurality offirst wires 110 having linear density larger than 900 Denier, thepuffy layer 100 has a high degree of puffiness in thestereoscopic area 600. More particularly, thefirst wires 110 of thepuffy layer 100 can be seen as the frame in thestereoscopic area 600. Since the linear density of thefirst wires 110 is larger than 900 Denier, i.e. having wider diameter, thefirst wires 110 occupy more space such that they give a high degree of puffiness to thepuffy layer 100. - As shown in the embodiment in
FIG. 1A , thepuffy layer 100 is composed of thefirst wires 110 disposed as multiple stacks. In other words, thefirst wires 110 can be interlaced on different planes. In a different embodiment shown inFIG. 1B , however, thepuffy layer 100 is composed of thefirst wires 110 disposed as a single layer. More particularly, thefirst wire 110 is inherently puffy, hence it is able to show its puffy characteristic well when it is not gripped and limited by thefirst knit layer 310 and thesecond knit layer 320 in thestereoscopic area 600. - As shown in the embodiment in
FIG. 1B , the gap D400 between thefirst knit layer 310 and thesecond knit layer 320 in theflat area 400 is substantially larger than the denier of thefirst wire 110. Specifically, since thefirst wire 110 is puffy and occupies space, the gap D400 between thefirst knit layer 310 and thesecond knit layer 320 in theflat area 400 must not be smaller than the denier of thefirst wire 110 at its most compressed state. In one embodiment, 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, which are respective the upper limit and the lower limit for knitting the wires having linear density larger of 900 denier. - As shown in the embodiment in
FIG. 1A , thefirst knit layer 310 and thesecond knit layer 320 pass respectively through thepuffy layer 100 and interweave in theflat area 400 to limit the gap between thefirst knit layer 310 and thesecond knit layer 320 in theflat area 400. More particularly,FIGS. 2A, 2B, and 2C are respectively schematic views ofregions FIG. 1A . Taking a different point of view, as shown in the embodiment inFIG. 2D , thefirst wire 110 of thepuffy layer 100 is the floating yarns disposed between thefirst knit layer 310 and thesecond knit layer 320 when weaving the two. The stereoscopic area 600 (seeFIG. 1A ) is the area that thefirst knit layer 310 and thesecond knit layer 320 interweave without passing through thepuffy layer 100. - Moreover, localized puffy effect can be produced in the stereoscopic weft knitted
fabric 900 of the present invention. As shown in the embodiment inFIG. 3A , thefirst wire 110 darts in and out thefirst knit layer 310 without interweaving with thefirst knit layer 310 and thesecond knit layer 320 in the stereoscopic area 600 (seeFIG. 1A ). Accordingly, thefirst wire 110 substantially fill the space between thefirst knit layer 310 and thesecond knit layer 320 in thestereoscopic area 600, such that it makes thestereoscopic area 600 puffy. Before thefirst wire 110 darts in thefirst knit layer 310 to form one side of it, the weaving process undergoes “ring-shifting”, wherein the rings on the lower knitting needle are shifted to the upper knitting needle. After then, as shown inFIG. 3C , thefirst wire 110 enters the space between the lower knitting needle and the upper knitting needle. Afterwards, the weaving of thefirst knit layer 310 and thesecond knit layer 320 continues.FIG. 3E is a schematic view showing the weaving inregion 440 of the embodiment shown inFIG. 3A . - The
first knit layer 310 and thesecond knit layer 320 can be interwoven via various methods. As shown in the embodiment inFIG. 4A , afirst yarn 301 forms a plurality offirst loops 331 by the sequential winding movement ofknitting needle 500, wherein the plurality offirst loops 331 are interlocked to form thefirst knit layer 310. Thefirst yarn 301 passes through thepuffy layer 100 in theflat area 400 after forming the last one of thefirst loop 331. Afterwards, it forms a plurality ofsecond loops 332 by the sequential winding movement ofknitting needle 500, wherein the plurality ofsecond loops 332 are interlocked to form thesecond knit layer 320. This interweaving method is preferably used in the junctional zone between thestereoscopic area 600 and theflat area 400 to produce localized puffy effect in the stereoscopic weft knittedfabric 900. The interweaving methods used in the embodiments shown inFIGS. 4B to 4D are the same. Moreover, different interweaving methods can be used in accordance with the design, manufacturing, or application requirements. - As shown in another interweaving method used in the embodiment in
FIG. 4E , thefirst yarn 301 forms m number offirst loops 331 by sequential winding movement and passes through thepuffy layer 100 in the flat area 400 (seeFIG. 1A ). After forms athird loop 333, it passes through thepuffy layer 100 in theflat area 400 and forms n number offirst loops 331 by sequential winding movement. Thesecond yarn 302 forms a plurality ofsecond loops 332 by sequential winding movement. The m and n number offirst loops 331 are interlocked to form thefirst knit layer 310, wherein thethird loop 333 and the second loops are interlocked to form thesecond knit layer 320. This interweaving method is preferably used in theflat area 400 betweenstereoscopic areas 600. The interweaving method used in the embodiment shown inFIG. 4E is the same. The difference between the embodiments shown inFIGS. 4E and 4F is that there is no empty exit between the m and nfirst loops 331 in the embodiment shown inFIG. 4F . - 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
FIG. 1A , thefirst knit layer 310 and thesecond knit layer 320 respectively protrude outward in thestereoscopic area 600. In other words, the stereoscopic weft knittedfabric 900 protrudes outward on both sides in thestereoscopic area 600. In different embodiments, however, the stereoscopic weft knittedfabric 900 protrudes outward only on one side in thestereoscopic area 600 in accordance with the design, manufacturing, or application requirements. As shown in the embodiment inFIG. 5 , thefirst knit layer 310 of theknit layer 300 protrudes outward in thestereoscopic area 600, wherein thesecond knit layer 320 stays flat. - 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.
