Problems solved by technology

Drawing lasts based on experience in the market is not accurate. The lasts obtained by drawing lasts are only the appearance but not the essence of a good last. We can only hold back the high-end foreign lasts.

Abstract

The invention provides a shoe last manufacturing method based on exclusive oil sludge through a leather shoe inner cavity. The method comprises the following steps that step one, formula raw materialsare blended to make the oil sludge; step two, the oil sludge is baked; step three, the oil sludge is arranged in an inner cavity of a sample leather shoe in a filling mode; step four, the oil sludgeis filled and applied; and step five, the oil sludge is refined. According to the shoe last manufacturing method with the exclusive oil sludge, the exclusive oil sludge is used as the raw material andis matched with a pure handmade manufacturing method to solve the problems of an existing method that the shoe last can not be drawn accurately according to the shoe and based on experience, and according to the drawing method, only the appearance of the shoe last is obtained and the quintessence of a good shoe last is not acquired. The shoe last manufacturing method based on the oil sludge is anovel method, according to the converse shoe last manufacturing method of filling the oil sludge into the shoe cavity, a shoe last similar to or the same with an original shoe last is obtained. According to the converse method, advantages of the original product are kept, an original shoe last manufacturing period is shortened, the cost is lowered and the better shoe last is obtained.

Description

technical field [0001] The invention designs a manufacturing process of a shoe last, specifically, a process method of imitating a shoe last through a leather shoe inner cavity by using special sludge. Background technique [0002] A shoe last is a model for shoemaking. The structure and shape of the shoe tree determine the shape and wearing comfort of the shoe. With the development of social economy, people pay more attention to the comfort of shoes. In the market, it is not accurate to draw shoe lasts based on experience. The lasts obtained by drawing lasts are only the appearance but not the essence of a good last. We can only hold back the high-end foreign lasts. Therefore it is necessary to improve this. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies of the prior art, the present invention provides a method for making lasts through the inner cavity of leather shoes based on special sludge. This method can obtain shoe lasts...
