Embodiment 1

[0040] Such as figure 1 As shown, two layers of wrapped yarn are embroidered on the head, middle and tail of the vamp body 1, the second layer of wrapped yarn embroidered on the head is generally bow-shaped, and the stitches are wavy; the embroidery is in the middle of the vamp The second layer of wrapping yarn is close to a parallelogram as a whole, and the stitches are parallel straight lines; the second layer of wrapping yarn embroidered on the tail of the shoe upper is almost semicircular as a whole, and the stitches are arc-shaped. The second layer of wrapped yarn embroidered in the middle of the shoe upper is partially embroidered on the second layer of wrapped yarn at the tail to form a third layer of wrapped yarn, and the third layer of wrapped yarn is visually presented as a fan-shaped pattern.

Embodiment 2

[0042] Such as figure 2As shown, the inner periphery of the notch 4 of the upper body 1 is provided with an inner ring 2 for tying shoelaces. On the basis of Embodiment 1, an outer ring 3 is provided on the outer periphery of the upper body 1. The outer ring 3 is connected with the vamp body 1 as a whole. When making finished shoes, the outer ring 3 can be embedded in the sole, and the outer ring 3 is used as a reinforcing rib arranged between the upper and the sole, which can disperse the stress on the joint between the upper and the sole during the use of the shoe. Pull to avoid opening. The test results show that the maximum tensile force that can be borne between the vamp and the sole increases by 40-70% after the outer ring 3 is added.

Embodiment 3

[0044] The upper thread and bottom thread made of polyester, and the wrapping yarn made of polyester wrapped in polyester are selected as production materials, and the upper thread and the bottom thread are embroidered on the hot-melt lining by using a computer winding embroidery machine to embroider the wrapping yarn on the hot-melt lining to form a shoe upper. The embroidery layers, patterns and stitches of the upper are as follows figure 2 shown. Put the embroidered upper into the hot-melt glue machine for dissolution and shaping. The results show that when the temperature is set to 200°C, the hot-melt lining is completely dissolved in about 9s. After taking out the upper, its spatial structure is stable, and all indicators meet the production standards.

Abstract

The invention discloses a production method of a computer-aided embroidery-formed vamp. The production method comprises the following steps: designing a plane template of the computer-aided embroidery-formed vamp, designing an embroidery pattern of the computer-aided embroidery-formed vamp, embroidering the computer-aided embroidery-formed vamp on a machine, and post-finishing the computer-aided embroidery-formed vamp and the like. By the production method, a computer-aided embroidery machine is used for embroidering a wrapped yarn into the one-piece formed vamp, and tailoring and sewing are not required for once forming, so that the conventional vamp producing technology is overturned; the production process is environmentally friendly, material-saving and high in degree of automation; the produced vamp has the characteristics of lightness, thinness, breathability, comfort, foot fitness, customizability and the like.

Description

technical field [0001] The invention belongs to the technical field of shoes, and in particular relates to a method for making computer-embroidered vamps. Background technique [0002] Shoes are mainly composed of two parts: the upper and the sole. At present, the uppers of casual shoes are mainly made of leather, leather, cloth and other materials. Some accessories waste materials and rely on a lot of labor throughout the production process. In addition, leather and leather uppers have poor air permeability, and the products are more polluted. [0003] Because it has to go through the steps of immersion, degreasing, dehairing and liming, deliming, softening, pickling, tanning, neutralization, retanning, dyeing and fatliquoring, etc., there are many processes and the use of chemical materials is complicated, so some pollutants in the tanning wastewater For example, the concentrations of COD, sulfide, and ammonia nitrogen are relatively high. Moreover, only about 30% of r...
