The embodiments set forth herein, and vice versa, will provide a more thorough and complete and complete disclosure of the scope of the present invention, and the present invention will only be The scope of the patent application is defined.

[0039]

Please refer to Fig. 1, which is a schematic view of the elastic composite yarn of the present invention. As can be seen from the figure, the elastic composite yarn 1 comprises a core yarn system 10 and a coated yarn system 20, and the core yarn system 10 is a yarn in which the elastic core yarn 11 and the gasified separated core yarn 12 are juxtaposed as the yarn of the elastic composite yarn 1. The shaft core has a plurality of inelastic yarns 21 interlaced and wrapped around the periphery of the core yarn system 10. The non-elastic yarn 21 of the drape yarn system 20 can be selected according to actual needs, and can be selected by single layer, double layer or multi-layer winding, and the whole yarn can be increased by controlling the difference of the twisting direction (S捻 or Z捻) during the winding process. The strength of the line.

[0040]

In other words, the technical feature of the elastic composite yarn 1 of the present invention is that the difference in the elastic modulus between the two different materials of the elastic core yarn 11 and the gasification separated core yarn 12 is achieved by using a gasification separation core having a lower modulus of elasticity. The yarn 12 can reduce the amount of tensile deformation of the elastic core yarn 11 due to the pulling speed during the twisting process, thereby limiting or restraining the ductility of the elastic core yarn 11, thereby improving the weavability of the elastic composite yarn 1. In practice, the material of the gasification separated core yarn 12 may include polyester and Nylon, the wire diameter is between 30 Danny and 200 Danny, and the diameter of the non-elastic yarn 21 is between 30 Danny and 1200 Danny. between.

[0041]

It is further explained that although the gasification split core yarn 12 and the conventional hot melt yarn described in the present invention both have hot melt characteristics, the related physical properties are not the same, and the main difference is that the conventional hot melt yarn is adhered after being melted. On the other yarn materials, the yarn properties are further affected. However, the gasification and separation core yarns 12 are directly vaporized and disappeared after being processed by a high temperature process, and do not stick or damage other yarn structure. In practice, the gasification temperature range of the gasification separated core yarn 12 is between 50 ° C and 180 ° C.

[0042]

Further, before the elastic composite yarn 1 is processed by the high-temperature process, since the gas-separated core yarn 12 restricts the amount of deformation of the elastic core yarn 11, the stretchability or ductility is similar to that of the conventional non-elastic yarn. In the weaving process, no additional tension adjustment device is required to adjust the yarn tension, so the weaving speed can be greatly increased to increase the productivity.

[0043]

Since the elastic composite yarn 1 of the present invention is in the process of twisting and weaving, the deformation amount of the elastic core yarn 11 is restrained by the gasification and separation core yarn 12, and after being woven into a fabric, the fabric is shaped or finished. After the high-temperature process, the gasification separated core yarn 12 is vaporized and disappeared from the elastic composite yarn 1, and the elastic core yarn 11 is restored to its elasticity. However, because the pre-tension and tensile deformation of the elastic core yarn 11 during the weaving process are smaller than those of the conventional elastic yarn, the shrinkage deformation of the overall fabric is not large, and the expansion allowance of the elastic fabric is also It is superior to elastic fabric woven from traditional elastic yarns.

[0044]

Please refer to Fig. 2 and Fig. 3 at the same time. This creation also proposes the elastic woven upper fabric 100 woven by the elastic composite yarn 1, and the elastic woven upper fabric 100 series using the woven shuttle looms according to the upper composition 70 The woven shuttle looms comprise at least two pan heads, a squeaking machine, a plurality of triangular heddle elements, and a plurality of weft yarn feeding mechanisms. Among them, the configuration of the upper pattern 70 can be used to simultaneously perform full-width weaving, thereby increasing product productivity.

[0045]

In practice, the elastic woven upper fabric 100 can be broadly divided into a warp yarn system 110, a weft yarn system 120, and an elastic region 130. The warp yarn system 110 includes at least a plurality of first warp yarn units 111 and a plurality of second warp yarn units 112, and at least two of the disc heads respectively transport a plurality of first warp yarn units 111 and a plurality of second warp yarn units 112. The weft yarn system 120 is composed of a plurality of weft yarn units 121, and the plurality of weft yarn feeding mechanisms can respectively transmit a corresponding plurality of weft yarn units 121 according to the upper surface pattern 70, wherein the type of the weft yarn unit 121 can include the disclosure of the present invention. Elastic composite yarn 1.

[0046]

The elastic woven upper fabric 100 is embossed according to the upper pattern 70 to lift a plurality of corresponding first warp yarn units 111 and a plurality of second warp yarn units 112 and cooperate with a plurality of weft yarn units 121 in a single weaving process. Interlaced and woven. Through the combination of the warp yarns 110 and the weft yarns 120 of different wire diameters and according to the plan of the shoe face composition 70, it is possible to weave the inner and outer layers of different tactile cloth tissues. The flexible woven upper fabric 100 can be knitted by a single weaving process, which can effectively reduce the time and cost required for the subsequent secondary processing. The upper pattern 70 includes a shoe contour, a yarn density, a stencil pattern, a pore plan, and the like.

[0047]

Further, the embossing machine and the plurality of triangular heddle elements can be used to correspondingly lift or offset the plurality of first warp yarn units 111 and the plurality of second warp yarn units 112 for stereoscopic oblique weaving of the venting aperture. To increase the breathability of the elastic woven upper fabric 100.

[0048]

In practice, a portion of the elastic region 130 of the elastic woven upper fabric 100 is woven by the elastic composite yarn 1 for the weft yarn unit 121. The elastic region 130 may include a toe portion, a hoe portion, and a collar portion. , the shoe part, the heel part, the support part or a combination thereof.

[0049]

Referring to FIGS. 2 and 4 simultaneously, the warp yarn system 110 may further include a third warp yarn unit 113 for use as a "turning yarn", since the third warp yarn unit 113 is independent of the first warp yarn unit 111 and the second warp yarn unit 112. In addition, the third warp yarn unit 113 is independently disposed on the third pan head or creel structure. Compared with the foregoing, the first warp yarn unit 111 or the second warp yarn unit 112 is directly lifted by the embossing machine, the triangular warp element can be used to lift or offset the corresponding third warp yarn unit 113 to perform oblique stereoscopic The interlaced weave can be woven into a plurality of venting apertures to increase the breathability of the elastic woven upper fabric 100. Moreover, the thresholding of the tissue pattern can be reduced by the independent operation of the third warp yarn unit 113 to enhance the diversity of the cloth tissue.

[0050]

The wire diameter of the first warp yarn unit 111 is between 100 denier and 1200 denier, and the diameter of the second warp yarn unit 112 is between 100 denier and 1200 denier, and the line of the third warp yarn unit 113 The diameter range is between 100 Danny and 1200 Danny.

[0051]

In practice, the elastic region 130 of the second woven elastic woven upper fabric 100 can also be woven by using the elastic composite yarn 1, wherein the elastic region 130 can be selected and designed on the toe portion according to actual needs. The head portion, the collar portion, the shoe portion, the heel portion, the support portion or a combination thereof.

[0052]

Please refer to Fig. 1, Fig. 2 and Fig. 5 at the same time. When the elastic woven upper fabric 100 is woven into the embryo fabric, the high temperature process such as hot air leveling and ironing can make the upper pattern 70 smoother. According to the contour of the upper, the cutting process is performed by using a die cutter, a shearing or a laser cutting to obtain an elastic woven upper 220, and then assembled on the sole structure 210 by various joints such as stitching, joining, bonding, etc., to form a shoe. Class component 200. The hoe portion of the footwear assembly 200 is woven by the elastic composite yarn 1, which makes it more elastic and less prone to wear.

[0053]

Further, after the elastic woven upper fabric 100 is subjected to an overheating process, the vaporized split core yarn 12 in the elastic composite yarn 1 is vaporized to restore the elasticity of the elastic core yarn 11 to make the footwear assembly 200 more wearable. elasticity. In practice, the elastic woven upper 220 may be disposed on the periphery of the shoe model and then formed into a process, and the elastic woven upper 220 is formed into a three-dimensional upper to facilitate subsequent assembly work.

[0054]

In summary, the characteristics of the elastic composite yarn proposed by the present invention can break through the dilemma that the elastic fabric cannot be mass-produced due to limitation of the elastic yarn. Furthermore, this creation proposes that the concept of the yarn is independent of the warp yarn, which can reduce the technical threshold of the woven fabric's organization and composition, and greatly increase the diversity of the tissue composition.

[0055]

In addition, this creation uses a multi-disc woven woven looms with different diameters of the warp and weft yarns. According to different needs, we can weave a three-dimensional touch with a thick difference in a single process and weave different functions of the inner and outer structures. Fabric organization and application to the field of footwear to shorten the manufacturing time of footwear can significantly reduce the associated costs to give back to consumers.
