Description

3D prints vamp and sports shoes who makes thereof

Technical Field

The utility model relates to a sports shoes especially relates to a 3D prints vamp and sports shoes who makes.

Background

The sports shoe manufacturing is a technology-intensive production chain, which relates to a plurality of links such as design, CAD modeling, wood pattern carving, mold testing, mold opening, modification, production and the like, and has the disadvantages of long research and development production period, complex process technology and incapability of eliminating manual operation, so the shoe manufacturing industry is one of the industries which are difficult to realize automation.

Currently, most common athletic shoes employ a textile-containing upper. For example, the vamp made of materials such as polyvinyl chloride (PVC), PU (polyurethane), nubuck, superfine fiber, natural leather, mesh cloth and the like through processes such as die pressing, hot melting, weaving and the like can provide certain wrapping, protecting and warm-keeping performances. The process has high complexity, high labor cost and time cost, and can cause certain environmental pollution.

Human athletic activities often place higher functional demands on the upper. For example, the upper and instep must have good fit, the material must be comfortable, and elastic; ventilating, radiating, absorbing moisture and releasing sweat; light weight to avoid burden in movement; reduce friction between the foot and the upper, etc. In addition, when manufacturing a shoe upper, various conditions such as fashion property, material compatibility, mass production speed, manufacturing cost, market competitiveness, and the like are considered, and a comprehensive and effective solution is provided for the above contents.

The first prior art is as follows:

the traditional sports shoes generally adopt a mesh surface shoe style structure. A fabric with mesh openings is a mesh cloth. The woven mesh cloth and the knitted mesh cloth are provided, wherein the woven mesh cloth is white-woven or yarn-dyed, has good air permeability, and is stiff and comfortable after being bleached and dyed. In the footwear and apparel industry, in order to achieve the effects of light weight and ventilation, large-area mesh cloth can be adopted for running shoes and tennis shoes; the shoe tongue part of the basketball shoe is also used for the mesh fabric product. The mesh is a special vamp material, and nylon mesh is mostly adopted for shoes which require light weight and ventilation, such as running shoes and the like. However, to meet the wearing requirements of sports, it is compounded and special fiber and scientific high-strength network designs are used. For example, the sandwich mesh cloth is a double-needle-bed warp knitting mesh cloth, which consists of a mesh surface, connecting monofilaments and a plain cloth bottom surface, and is named as the sandwich mesh cloth because the structure of the three-dimensional mesh cloth is very similar to a western sandwich hamburger.

The mesh surface shoes have the advantages that:

because the feet sweat a lot after the sports, the moisture and the foot odor inside the sports shoes are easily caused. Therefore, a pair of breathable net shoes is very important. The net surface shoes have air permeability compared with the common leather surface sports shoes, and can reduce the temperature inside the sports shoes and lead the air to circulate. Because the vamp of the breathable net-surface shoe is made of the net surface, the breathable net-surface shoe is comfortable to wear and not easy to wet feet, and can be played more excellently during sports. The upper support has a reinforced design relative to the woven upper, i.e., the athletic shoe deforms greatly during vigorous activity, and the upper secures the foot to the sole. However, the better the upper supports, but the comfort is low and the weight is heavy. The mesh-surface shoes usually fill certain foam in the tongue and the heel, so that the shoes are more comfortable to wear, and the existing woven vamp sneakers do not have the design of partial filling. The adjustable flexibility of the sports shoe is improved by the design of the shoe tongue, and the probability that the shoe upper presses the instep can be reduced by a person with high instep as long as the person loosens the shoe lace slightly.

The mesh shoes have the following defects: the upper is relatively complex, has poor wrappability, is more breathable than ordinary leather-faced athletic shoes, but is not as breathable as a woven upper. In order to compensate for comfort, the vamp is generally added with sponge, and the filling thickness of the sponge reduces the breathability of the part which can be added. The middle-open type vamp depends on the shoelace to adjust the wrapping performance, so the number of shoelace holes is very large, and the shoes are troublesome to put on and take off. The upper is better supported, but is relatively less comfortable and weighs much more than a woven upper. The process of the mesh-surface shoes is complex, the working procedures for manufacturing the vamps are more, and the vamps can not be directly molded with the soles. This causes a factory to recruit a large number of vamp sewing workers, and also needs the cost of various raw materials such as glue, which is a relatively large enterprise cost burden.

The second prior art is:

the braided shoe upper is gradually becoming the main shoe upper of the sports and leisure shoes at present, and is woven by a plurality of special yarns through the programming of a computer machine in advance. With the advent of the flying-woven shoes of Nack and Adida, the weaving technique has raised a fashion trend in the shoe industry. The woven shoe upper is programmed in advance by a computer, and then integrally knitted and formed, so that various working procedures of the shoe upper are reduced, the shoe upper is directly formed with the shoe sole, and the efficiency is improved.

The weaving process has the advantages that:

the nature of the woven material is that a thread is interwoven to form a surface product no matter what name the woven material is, the material of the thread is polyester sand thread, namely the familiar polyester material is made into a thread state, although the clothes made of the polyester material have good strength, good elasticity and wear resistance, the clothes have poor air permeability in a not good place, the woven vamp can be supplemented with different knitting densities according to different shoe parts in the vamp forming process to achieve the effect of combining softness and hardness, an intuitive air vent can be formed by only increasing the distance between the fine adjustment lines of the weaving density, thereby overcoming the defect of the material embodied in sports products, so to speak, the material is better applied by a scientific and technological method, such cases are not uncommon, for example, in functional tights, where differences in the perspiration-permeability of the finished material are caused by differences in the weaving pattern. Meanwhile, the sports shoe with the knitted vamp is a whole piece from the toe to the ankle, can effectively fit with the whole instep, enables the vamp to be attached to the instep, and meanwhile ensures that the vamp has good flexibility and brings comfortable feeling to people.

The disadvantages of the weaving process are:

because the whole vamp is a layer of cloth, the protection effect on the foot in the process of sports is very weak. For example, high-intensity sports such as basketball can cause sprain and injury of athletes. To compensate for this, the stability of the sports shoe itself is mostly ensured by two ways: firstly, heightening the upper to increase the area of the sports shoe for wrapping the feet so as to stabilize the sports shoe; secondly, a TPU sheet which is stable enough is added on the heel of the shoe, so that the feet can be stable when falling to the ground. Both of these approaches inevitably add weight and complexity to the athletic shoe. For the same reason, the impact strength of the vamp is limited, the durability is poor and the vamp is easy to break. In order to better control the production cost, a great deal of sneakers with knitted uppers with tongues integrated with the uppers are derived from the process. The shoe vamp has poor foot feeling, and the phenomenon that the shoe tongue presses the instep, namely, the artery of the instep at the shoe tongue is pressed, so that the blood circulation in the movement is influenced. In addition, the woven surface is soft, the gaps are large, the cleaning is troublesome, and the vamp can be fluffed or broken if the user leaves little attention. Generally, the dirt is scrubbed by using a wet cloth, and the wet cloth is repeatedly scrubbed by being stained with laundry detergent or cleaning solution. Brushing up the woven shoe upper with a hard brush may result in fuzzing and affect the life of the sports shoe.
