Benefits of technology

The present invention is about providing a non-sewing material for a footwear upper that has incorporated the base portion of fabric that has hitherto been disposed of, which helps in maximizing the use of material. Additionally, the invention provides a wing portion on the outer portion of the upper that acts as a support portion, minimizing the waste of material for forming the support portion and improving economic efficiency. Furthermore, the bottom portion of the upper is easily formed on the extending wing portion, thereby improving the process efficiency and minimizing the defective rate of a product.

Problems solved by technology

However, the support portion occupies a large area of the fabric, thus causing a waste of the fabric, and besides, the formation of the support portion leads to an inefficient process.
Particularly, portions of the fabric other than a portion on which the upper is formed are disposed of, thus resulting in the loss of the fabric and consequently the waste of the material.
Such an operation requires highly skilled workers and increases a defective rate.

Abstract

A material for a footwear upper, includes a first side corresponding to an inner foot top and an inner side of a foot, a second side corresponding to an outer foot top and an outer side of the foot and extending outwards from an end of the first side to face the first side, a first wing portion extending outwards from the first side in a wing shape, and a second wing portion extending outwards from the second side in the wing shape. The first side and the second side, the first side and the first wing portion, and the second side and the second wing portion are integrated with each other, respectively so that a loss of the material may be reduced and manufacturing efficiency may be improved.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS AND CLAIM OF PRIORITY[0001]The present application claims the benefit of Korean Patent Application No. 10-2014-0045058, filed Apr. 15, 2014 in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates, in general, to a non-sewing material for a footwear upper, a footwear upper and footwear using the material, and, more particularly, to a non-sewing material for a footwear upper, a footwear upper and footwear using the material, in which a wing is provided on each of an inner side and an outer side, thus reducing a loss of the material and improving manufacturing efficiency.[0004]2. Description of the Related Art[0005]Generally, footwear includes two main members, i.e., an upper and a sole structure. The upper is secured to the sole structure and defines an opening in the footwear to receive the foot comfortably and safe...
