Description

Technical Field

[0001] This invention relates to the field of textile fabric weaving, and in particular to a locally elastic shoe material and its manufacturing method. Background Technology

[0002] Due to the accelerated pace of technological modernization, footwear materials now need to go beyond simply meeting the requirements of upper processing. Greater emphasis is placed on comfort, craftsmanship, feel, quality, style, and design. Partially elastic footwear materials typically involve laminating a non-elastic textile fabric with another elastic one, achieving a localized elastic effect. However, the non-elastic portion of this partially elastic material still retains some elasticity, while the elasticity of the original textile fabric is not very good. This results in a failure to provide adequate support and comfort for the feet. Furthermore, the two materials need to be sewn together or glued to the upper, adding extra steps and introducing polluting chemicals, while also reducing production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a locally elastic shoe material and its manufacturing method, which can achieve local elasticity in a designated area of ​​the shoe material, changing with the tension and relaxation of the foot muscles, and achieving a tighter fit.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a locally elastic shoe material, the shoe material comprising an upper layer, the upper layer being woven from a circular ground comb GB1 using a multifilament yarn knitting chain structure, a jacquard layer superimposed on the upper layer, the jacquard layer comprising an elastic zone and a non-elastic zone, the elastic zone being woven from a first pair of jacquard combs using a multifilament yarn mesh structure, and the non-elastic zone being woven from a first pair of jacquard combs using a multifilament yarn dense weave structure; the circular ground comb GB1 is woven with a padding yarn number of 1-0 / 0-1 / / ; the first pair of jacquard combs are woven with a padding yarn number of combinations varying from 0, 1, 2, 3 stitches as the basic lateral movement unit; a patterned comb locally elastic layer is provided on the elastic zone.

[0005] Furthermore, the partial elastic layer of the comb is formed by overlapping and weaving spandex weft fibers onto the mesh structure layer.

[0006] Furthermore, the fineness of the multifilament yarn is 70-300D, and the fineness of the spandex in the spandex weft is 70-1400D.

[0007] Furthermore, the multifilament yarn is composed of one or more of the following: nylon fiber, polyester fiber, vinylon fiber, acrylic fiber, synthetic fiber, polyethylene fiber, aramid fiber, and polymer fiber.

[0008] Furthermore, the surface layer is formed by one or more looped ground combs in conjunction with looped ground comb GB1 using multifilament yarns in a chain weave or weft weave structure. The one or more looped ground combs are superimposed on the looped ground combs in a movement pattern with the padding yarn numbers 1-0 / 0-1 / / or 0-0 / 1-1 / / .

[0009] Furthermore, the elastic zone is formed by the second pair of Jacquard guide bars in conjunction with the first pair of Jacquard guide bars using a multifilament yarn mesh weave structure; the non-elastic zone is formed by the second pair of Jacquard guide bars in conjunction with the first pair of Jacquard guide bars using a multifilament yarn dense weave structure, and the second pair of Jacquard guide bars in conjunction with the first pair of Jacquard guide bars uses a combination of arbitrary stitches with four stitch pitches of 0, 1, 2, and 3 as the basic lateral movement unit to create a combination of padding yarn numbers.

[0010] A method for manufacturing a locally elastic shoe material, the method comprising the following steps: Step S1: The surface layer of the shoe material is formed by weaving multifilament yarn using a looped comb GB1. Step S2: Using the jacquard function of the first pair of jacquard combs, jacquard layers of various shoe materials of different patterns are woven with multifilament yarns. Mesh structures need to be woven in the elastic area of ​​the jacquard layer, and dense structures need to be woven in the non-elastic area of ​​the jacquard layer. Step S3: Overlay spandex weft through the weft-inserting comb in the mesh area woven by the Jacquard comb. Through the elasticity of spandex and the deformable structural elasticity of the mesh structure, a local elastic layer of the comb is formed in the mesh area of ​​the fabric.

[0011] Furthermore, step S1 further comprises: the looping ground comb GB1 is woven in a movement pattern with padding yarn numbers of 1-0 / 0-1 / / , and the surface layer is formed by one or more looping ground combs in conjunction with the looping ground combs using multifilament yarn running chain structure or weft weft structure, and the one or more looping ground combs are superimposed on the looping ground comb GB1 in a movement pattern with padding yarn numbers of 1-0 / 0-1 / / or 0-0 / 1-1 / / .

[0012] Furthermore, step S2 further comprises: utilizing the Jacquard function, the elastic zone is formed by the second pair of Jacquard guide bars in conjunction with the first pair of Jacquard guide bars using a multifilament yarn mesh structure; the non-elastic zone is formed by the second pair of Jacquard guide bars in conjunction with the first pair of Jacquard guide bars using a multifilament yarn dense weave structure, wherein the second pair of Jacquard guide bars in conjunction with the first pair of Jacquard guide bars uses a combination of 0, 1, 2, and 3 stitches as the basic horizontal movement unit to create a combination of padding yarn numbers.

[0013] Furthermore, the fineness of the multifilament yarn is 70-300D; the fineness of the spandex in the spandex weft is 70-1400D.

It realizes local automatic adjustment of the tightness of wearing, changes with the tension and relaxation of the foot muscles, achieves a tighter fit, and adds assistance to sports and fitness.
