[0006] In view of the related technologies mentioned above, the inventor believes that there is an existing shoe upper filling material which is made by mixing leather filling powder and adhesive, but after a period of time, the adhesive is easy to use due to various properties of the adhesive. Failure, such as the aging, oxidation, and insufficient tensile strength of the adhesive, etc., make the shoe upper filling material easy to deform, resulting in short durability of the three-dimensional maintenance of the leather upper, and even causing abnormal deformation of the shoe upper.

Abstract
The invention relates to the field of leather, and particularly discloses a method for preparing women's shoes capable of keeping three-dimensional for a long time by utilizing natural leather. The preparation method comprises the following steps of: preparing a leather shoe preparation material; taking a natural leather material, performing cutting, carrying out hot press molding on the cut natural leather, forming an inner concave surface on the inner upper surface of the leather shoe, forming an outer convex surface on the outer upper surface of the leather shoe, and cutting redundant leather; taking natural leather filling powder and an adhesive to prepare a vamp filler; filling the inner concave surface with the vamp filler, after the vamp filler is molded stably, polishing the innerupper and the outer upper of the leather shoe to manufacture the upper part of the leather shoe; bonding the upper part of the leather shoe with a sole to form a prefabricated leather shoe; drying, pulling and cleaning the prefabricated leather shoe, and shaping the leather shoe at a high temperature; sequentially subjecting the surface of the vamp to waxing, glue brushing, drying and cooling shaping treatment; and mounting a heel and an insole to obtain a finished product. The preparation method disclosed by the invention has the advantage that the female shoes can keep stereoscopic impression for a long time.
Description
technical field [0001] The present application relates to the field of leather, more specifically, it relates to a method for preparing women's shoes that can maintain a three-dimensional shape for a long time using natural leather. Background technique [0002] With the development of China's economy and the continuous improvement of people's living standards, people's demand for daily necessities such as clothing, shoes and hats has become increasingly strong, especially the women's shoes industry has ushered in new development opportunities, and leather shoes are a kind of clothing commonly used in life. Articles, leather shoes can increase a person's temperament and image, and are also a status symbol, which are very popular among women. [0003] Leather shoes are mainly made of leather materials. Leather is divided into two categories: natural leather and non-natural leather. However, people prefer leather shoes made of natural leather. With great development, in order...
