Shoe upper material is a material inspection body, is particularly important. The main test upper folding (including low note folding), yellowing resistance, color fastness friction, cracking strength. 1. Upper material folding test GB4689.9 country has developed a standard in 1984, sets out the conditions for the upper material at room temperature, the folding test, the method is more reliable. However, as China's vast, when worn under low temperature conditions, the upper sometimes cold cracking (split pulp or crack faces), so the shoe industry need to select low temperature flex materials for shoes, snow shoes and shoes etc. into the shoe production; 2.
