Method for manufacturing non buffing upper material of adhensive process having improved adhesion strength and non buffing upper material of adhensive process manufactured by this method

摘要

The present invention relates to a method of manufacturing a non-buffing upper material in an adhesion process with improved adhesion strength, and to a non-buffing upper material in an adhesion process produced by this method, and more specifically, to a low-grade split leather without surface treatment. (Split leather) by adjusting the napping properties and applying a fatliquoring agent to solve the problem of adhesion failure, while improving the basic physical properties of abrasion resistance, waterproofness, and fastness, especially in the bonding process, In addition, as the adhesive strength of the adhesive can have properties of 2.0kgf or more, and the buffing process and the primer treatment process are omitted in the bonding process as described above, the conventional 7-step bonding process is used as the 3rd step of the "adhesive application → drying → compression" process. It is possible to shorten it to a step-by-step process (see Fig. 1), which not only allows the shoe manufacturing line to be drastically reduced to within 30m, but also solves the problem of dust and noise in the workplace, easy space for the shoe manufacturing line, and uniform thickness A method of manufacturing a non-buffing upper material in a bonding process with improved adhesion strength, which enables the implementation of process reduction, workplace environment improvement, quality improvement, productivity increase, etc., and a non-buffing upper in the bonding process manufactured by this method It is about the subject matter.
