In the shoemaking industry, in order to rationally use shoemaking materials, correctly control the production process, objectively evaluate the quality of shoes in process and finished products, develop new products and conduct scientific research, it is inseparable from analysis and testing. Many raw and auxiliary materials are used in shoemaking, such as leather, artificial leather, textiles, adhesives, sole materials and so on. In order to use these raw materials reasonably and ensure the smooth production, it is often necessary to analyze and test them before use to see if they meet the production process and use requirements.
For example, by testing the physical and mechanical properties of leather, such as tensile strength, elongation, crack strength, air permeability, moisture permeability and water absorption, the durability and applicability of leather materials in shoemaking can be judged. The measurement of leather shrinkage temperature can determine whether leather will shrink and deform due to high temperature during the manufacturing process of vulcanized shoes. Through the measurement of adhesive force, it can be judged whether it can be used in the manufacture of adhesive shoes and whether it will open after being made into shoes. Through the appearance inspection and analysis of physical and mechanical properties of finished shoes, we can judge whether the quality of shoes is good or not and whether they meet the relevant standards. The results of finished product analysis and inspection can also guide and control production and make product quality stable.
