Description

Preparation method of electro-embroidery product, vamp and footwear product Technical Field The application relates to the technical field of embroidery, in particular to a preparation method of an electro-embroidery product, the electro-embroidery product, a vamp and a shoe product. Background Currently, in the field of electro-embroidering processes, conventional electro-embroidering methods mainly perform an embroidering operation on a base fabric. The process mode is widely applied to a plurality of industries such as clothing, home textile, decoration, bags, leather and the like for a long time, and plays an important role in meeting the decorative demands of people on various articles. From the market application, the conventional operation mode of the electric embroidery based on the base fabric is a mature and common technical means in the industry, and the conventional electric embroidery is exquisite embroidery patterns on advanced fashion or fine embroidery decorations in household articles. However, this base fabric-dependent electro-embroidery process gradually exposes a number of drawbacks in practical applications, mainly in the following aspects: First, the material utilization efficiency is low, and the wasting of resources is serious. The use of a base fabric means that a large amount of fabric resources are additionally consumed in the whole process of the electro-embroidery production. The corresponding base fabric must be equipped for each electro-embroidery operation, which not only directly increases the purchase cost of raw materials, but also causes serious resource waste when the base fabric is not an essential component of the final product in the subsequent product use process. For example, in many products requiring only an embroidered pattern as a decorative element, the base fabric is often partially cut out after embroidery is completed, or only serves as a temporary support to lose its actual value in the final product, which is contrary to the environment-friendly, sustainable development concept pursued by modern manufacturing industries. Secondly, the process flow is complex, and the production efficiency is low. The conventional electro-embroidering process relies on the base fabric, so that the whole production process becomes extremely complicated. Firstly, before the electro-embroidering operation, a series of pretreatment operations including cleaning, ironing, cutting and the like are needed to be carried out on the base fabric so as to ensure that the flatness and the dimensional accuracy of the base fabric meet the embroidering requirements, and the pre-working procedures are time-consuming and labor-consuming, and increase the complexity of production management. Secondly, in the process of electro-embroidery, due to the influence of the material characteristics of the base fabric, such as elasticity, thickness, texture and other factors, the quality problems of deformation, uneven stitch and the like of the embroidery pattern are easily caused. When the common knitted fabric is used as a base fabric, the fabric is easy to stretch and deform under the tension effect generated by the up-and-down movement of the embroidery needle due to certain elasticity, so that the embroidered pattern is contracted along the stitch direction and is stretched along the direction perpendicular to the stitch, and obvious deviation exists between an actually embroidered sample and a design pattern. This problem forces embroidery platemakers to repeatedly make plate-changing corrections, sometimes even requiring multiple plate-testing to meet design requirements, greatly affecting production efficiency and product lead time. Furthermore, after the electric embroidery operation is completed, complex post-treatment is required to be performed on the base fabric and the embroidery, such as trimming the edges of the redundant base fabric, cleaning to remove residual stains in the production process, and the like, and the additional procedures further increase the investment of manpower, material resources and time cost. Thirdly, the structural form of the product is limited, and the three-dimensional expressive force is insufficient. The electro-embroidering process based on the base fabric determines that the finished product always comprises the base fabric material, this inherent feature limits the independent application of the embroidered portion, and the presence of the base fabric significantly affects the permeability and the lightening of the final product. Even with thicker embroidery threads, the stereoscopic effect achievable by conventional electro-embroidery is relatively limited, and it is difficult to form an embroidery body having a remarkable three-dimensional spatial structure and self-supporting ability. In other words, the conventional electro-embroidery is essentially a two-dimensional decoration on the plane of the base fabric, and a three-dimensional embroidery st
