Seamless 3D flat knit vamp and manufacturing method thereof

Abstract

The present invention relates to a seamless 3D flat knit vamp comprising a vamp body integrally woven by flat knitting machine, wherein the vamp body comprises an outer layer and an inner layer coupled to the outer layer; the outer layer comprises an outer toe portion, an outer shoe body portion, an outer heel portion and an outer shoe mouth portion; the inner layer comprises an inner toe portion correspondingly disposed in relation to the outer toe portion, an inner shoe body portion correspondingly disposed in relation to the outer shoe body portion, an inner heel portion correspondingly disposed in relation to the outer heel portion, and an inner shoe mouth portion correspondingly disposed in relation to the outer shoe mouth portion. It has the advantages of convenient to process, good integrity, and comfortable to wear.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a seamless 3D flat knit vamp and manufacturing method thereof.[0002]Woven vamp has become a new product line which has the advantages of light, breathable and stylable, thus is welcomed by the market. However, current woven vamps are formed by firstly weaving a planar woven fabric, laying out several extended shoe-shaped vamps on the planar woven fabric, forming jacquard or hollow patterns on corresponding parts of the shoe-shaped vamps, and thereafter cutting the vamps by laser machines. However, it takes a long time for the laser machines to cut the vamps; the costs of the machines are also high. For some vamps, after being embroidered or adhered to other fabrics, it is necessary to carry out second cutting operation by laser machines. The manufacturing process is complex, and a large amount of edges, corners and remaining fabric will be wasted. Precise sewing is required for combining the planar vamp and the sole, ...

AI Technical Summary

Benefits of technology

The present invention provides a seamless 3D flat knit vamp that is convenient to process and manufacture, better in stability, and comfortable to wear. The manufacturing method of the invention increases production efficiency and manufactures shoes that are comfortable to wear and have stable structure. The technical effects of this invention are improved stability, comfort, and efficiency in the production of seamless shoes.

Problems solved by technology

However, it takes a long time for the laser machines to cut the vamps; the costs of the machines are also high.

The manufacturing process is complex, and a large amount of edges, corners and remaining fabric will be wasted.

Precise sewing is required for combining the planar vamp and the sole, otherwise the size and shape of the shoe will be affected, resulting in inconsistent shoe size and jeopardizing comfortability and aestheticness.

All the aforementioned causes high manufacturing costs of the shoes.

Besides, common woven vamps are made of softer fabric, thus the vamps are not firm enough and easily collapse, affecting the outer appearance of the vamps.

The production efficiency therefore still needs improvement; besides, there are glitches at intersecting portions of the sewn parts, thus affecting comfortability.
