By arranging the composition of the organization to simultaneously weave the full-width weaving, thereby increasing product capacity.

Using the first portion of the needle bed of the warp knitting machine to weave the first upper unit 10 according to the shoe profile 81, the second portion of the needle bed to weave the second upper unit 20 according to the shoe profile 81, and then according to different shoe profiles 81 Different weaving methods are used so that the shoe profile 812 does not create the dilemma of yarn separation due to cutting into the sock upper fabric 90.

If the traditional face-to-edge weave is used on the ridge boundary 811, the seam line will be obvious and affect the aesthetics, and the friction will be applied to the foot to reduce the comfort. To solve this problem, the present invention proposes to use the hollowing out. The design concept of the aperture 85 is to seamlessly connect the first upper unit 10 and the second upper unit 20 by means of the configuration of the hollowed holes 85 to facilitate the weaving of the warp knitting machine to hide the ridge boundary 811 and thereby maintain The aesthetics of the overall upper. In practice, the hollowed out aperture 85 can be designed according to the curvature of the sole of the shoe profile 81.

In other words, the shoe-shaped contour suture 88 is a face-to-face weave according to the joint planning to form a shoe-like profile 812, and the open-end contour 815 such as the waistline contour 8151 and the waistline of the shoe upper is a single layer. Weaving the weave to weave.

Further, the shoe profile 812 can be adapted to adjust the configuration of the tissue composition according to the actual needs of the actual shoe height. Furthermore, when the first upper unit 10 and the second upper unit 20 are knitted, a corresponding plurality of shoes may be added to the area to be reinforced (for example, a shoe upper, a shoe body, a shoe eye, a heel, etc.). Face reinforcement to increase the support of the upper.

Please refer to FIG. 3 and FIG. 4 at the same time to better understand the manufacturing process of the three-dimensional upper of the present invention. The present invention further provides a method of manufacturing a three-dimensional upper 98 comprising the following steps: S1, designing a tissue composition having at least one shoe profile and corresponding at least one connection point plan, each shoe profile including at least a shoe ridge boundary and a shoe profile. In practice, the shoe profile 812 may further include an open contour 815 such as a collar profile 8151 and a waistline profile 8152.

Further, according to the actual shoe type (for example, sports shoes, jogging shoes, basketball shoes, high shoes, etc.), the hollow hole 85 and the height of the shoe tube corresponding to the curvature of the shoe sole are designed, and further Adjust the relevant configuration of the organization's composition to increase the production capacity of the product and reduce the wear and tear of the sapwood.

In step S2, the at least one yarn is woven according to the tissue pattern by the warp knitting machine, and the first upper unit and the second upper unit corresponding to the contour are knitted. In practice, the first upper needle bed can be woven with the Jacquard flower device to weave the first upper unit 10, and the second partial needle bed is matched with the Jacquard flower device to weave the second upper unit 20. By arranging the full-width configuration of the composition to improve the weaving efficiency, the manufacturing time of the product can be reduced.

The upper yarn system can be a fiber yarn having a double melting point, and the different melting points of the core yarn and the coating layer of the fiber yarn can be utilized to achieve individual functional requirements. The outer coating layer having a lower melting point, in addition to improving the knitting processability of the three-dimensional upper fabric 100, can further increase the color fastness of the yarn fiber dyeing and finishing. However, a fiber core having a higher melting point provides the straightness required for the three-dimensional upper 98 to increase the structural integrity of the overall upper.

Further, in the process of drawing, the homogenous yarns having different melting points of the inner and outer layers can be prepared by controlling the difference in the degree of crystallization of the fibers or by coating and drawing, etc., and the main consideration is that the yarns of the same material are relatively similar. The physical properties can reduce the complexity of process parameter control during the weaving process. Furthermore, the yarn of the same material can reduce the difficulty of recycling the sapwood, increase the recycling ratio and reduce the related costs, and further achieve the purpose of environmental protection and energy saving.
