FIELD OF THE INVENTION

The present invention relates to a method for forming a textile article, and in particular to a method for forming a textile article that enables three-dimensional formation by including a textile having thermoplastic property.

BACKGROUND OF THE INVENTION

A conventional textile, after having being completely made, is generally a flexible article, which shows no strength for erection and is thus incapable of forming a three-dimensional article. On the other hand, a leather article, such as a shoe and a bag, is generally made by being divided into several individual and separate pieces of leather, which are then sewn or coupled together by other means to form a complete shoe or bag. Such a process requires first applying cutting operations to form those individual and separate pieces of leather according to a design drawing. The larger the number of the individual pieces is, the more the operation steps will be and thus the higher the cost will be.
Thus, it is desired to provide a method for making a textile structure that can be formed as a three-dimensional article, in order to overcome the problem of large number of operation steps and waste of cost.
