Description

Vamp with TPU yarn

Technical Field

The utility model relates to a vamp field especially relates to a vamp with TPU yarn.

Background

The existing decorations adopted in the shoe uppers mainly adopt a structure of combining screen cloth, a hot melt film and leather, and the decorations not only have strong stereoscopic impression and layering sense, but also have certain wear resistance of the hot melt film and the leather, so the decorations are deeply loved by the market. However, the ductility of the hot melt film is too small, so that aesthetic fatigue is easy to generate for people, modern people have no fresh feeling and cannot meet the aesthetic feeling of the modern people, and the design of adopting the hot melt film as an ornament on the vamp is gradually delaminated from the fashion; a large amount of sewage is generated in the manufacturing process of leather, and the sewage is organic wastewater with complex components and high concentration, contains a large amount of salts, grease, ammonia nitrogen, sulfides, chromium salts, and toxic and harmful substances such as wool, leather residue, silt and the like, and is extremely harmful to the environment and the health of people. Therefore, the use of less leather on the vamp, even without leather, is a measure for green production.

Therefore, the function of adopting a structure on the vamp to replace a hot melt film and leather has great significance.

In view of the above, the present inventors have made extensive studies on the composition and structure of shoe uppers, and have made this disclosure.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail with reference to the accompanying drawings and specific embodiments.

The utility model relates to a vamp with TPU yarn, as shown in fig. 1 to 3, this description describes with the position that fig. 2 shows. The utility model relates to a vamp with TPU yarn includes integrative vamp body of weaving, and the vamp body includes lower floor 1, middle level 2 and upper strata 3 by supreme setting down, and the bottom surface of upper strata 3 interweaves on middle level 2, and lower floor 1 arranges that middle level 2 corresponds upper strata 3 department, and the top surface of lower floor 1 interweaves on middle level 2's bottom surface, and upper strata 3 is the structural layer that forms behind the TPU yarn hot pressing. The upper layer 3 is a structural layer formed after the TPU yarn is hot-pressed, so that the upper layer has stronger texture, and the texture difference with the middle layer 2 is larger, so that the vamp with the TPU yarn has strong third dimension and layering; because the structural layer that the TPU yarn formed after the hot pressing has the wearability of preferred again, thereby makes the utility model relates to a vamp with TPU yarn still possesses the wearability of preferred in upper 3 departments. Set up the junction that lower floor 1 can protect upper strata 3 and middle level 2, avoid human foot direct and upper strata 3 and middle level 2 junction contact and friction, further increase the wearability.

The molecular structure of the TPU is formed by alternately reacting a rigid block obtained by reacting MDI or TDI and a chain extender and a flexible chain segment obtained by reacting diisocyanate molecules such as MDI or TDI and the like and macromolecular polyol. Has the characteristics of excellent high tension, toughness and aging resistance, and belongs to a mature environment-friendly material. Compared with other plastic materials, the TPU has higher strength and better toughness, and is different from other plastic materials under the excellent functional performances of wear resistance, high temperature resistance, cold resistance, oil resistance, hydrolysis resistance, aging resistance, UV resistance, high waterproof and moisture permeability, wind resistance, cold resistance, antibiosis, mildew resistance, heat preservation and the like.

After the TPU yarn is embroidered at the local position of the middle layer 2, the TPU yarn is melted by hot pressing, and an upper layer 3 with a protection effect is formed on the surface of the middle layer 2. The upper layer 3 is able to enhance the wear resistance of the middle layer 2 and to a further limited extent retain the softness of the middle layer 2. Upper strata 3 contrast leather and hot melt film, TPU yarn layer is more lightweight, can alleviate user's heavy burden. In addition, the thickness of the upper layer 3 or the number of the gaps on the upper layer 3 can be changed by adjusting the density of the embroidery texture of the TPU yarn, and then the utility model relates to an air permeability of a vamp with the TPU yarn. Through the matching of TPU yarns with different colors and the embroidering of patterns with different textures, the TPU yarn layer can present richer and more novel appearance effects than leather and hot melt films, and is more fashionable.

The middle layer 2 is provided with a positioning hole 21 for positioning the vamp on the mold. Thus, the positioning of the vamp in the mold is convenient, and the stable upper layer 3 structure is formed.

The upper layer 3 is provided with a plurality of first grooves 31 which are concave downwards, and the upper layer 3 is provided with convex edges 32 between the first grooves 31. The structural hierarchy of upper strata 3 has been deepened in the setting of first recess 31 and protruding edge 32, thereby makes the utility model relates to a vamp with TPU yarn has more the third dimension and the hierarchy.

A second groove 33 is opened on the groove bottom of each first groove 31. Set up second recess 33 and can deepen upper strata 3's structural level, further enhancement the utility model relates to a vamp with TPU yarn has more the third dimension and stereovision.

The middle layer 2 is interlaced on the upper surface of each ledge 32 and the middle layer 2 is partially exposed on the upper surface of the ledge 32. Make the decorative pattern of middle level 2 can show out partly at upper strata 3, increase the change of outward appearance, make the utility model relates to a vamp with TPU yarn has more novelty and fashion sense.

The bottom surface of the lower layer 1 is provided with a compensation groove 11 corresponding to the convex edge 32 in an upward concave mode, the structure in the compensation groove 11 extends upwards to the convex edge 32, and the convex edge 32 can be formed without adding materials.

The part of the contour line of the upper layer 3 interlaced with the middle layer 2 penetrates the middle layer 2 and is interlaced with the lower layer 1. So make the connection between lower floor 1, middle level 2 and upper strata 3 more stable, and then make the utility model relates to a structure of vamp with TPU yarn is more reliable.

The middle layer 2 is a fabric layer in the shape of a vamp. The lower layer 1 is a padding yarn layer with the same contour shape as the upper layer 3.

The above embodiments and drawings do not limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should be considered as not departing from the scope of the present invention.
