Method for manufacturing non buffing upper material of adhensive process with shorter adhensive process 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 capable of shortening the adhesion process, and to a non-buffing upper material in the adhesion process manufactured by this method, and more specifically, to a low-grade material without surface processing. By solving the problem of adhesion defects through control of nap and plasma treatment on the split leather of the product, the basic properties such as abrasion resistance, waterproofness, and fastness are improved, while buffing and primer are especially used in the bonding process. The adhesive strength with the shoe sole can have properties of 2.0kgf or more even without a treatment process, and as the buffing process and the primer treatment process are omitted in the bonding process as described above, the conventional 7-step bonding process is "applying adhesive → drying → It is possible to shorten it to a three-step process of the "pressing" process (see Fig. 1), and this allows the shoe manufacturing line to be drastically reduced to within 30m, as well as solving the problem of dust and noise in the workplace, and an easy space for the shoe manufacturing line A method of manufacturing a non-buffing upper material in the bonding process that can shorten the bonding process, which can shorten the process such as securing and realize uniform thickness, improve the workplace environment, improve quality, and increase productivity, and manufactured by this method. It relates to a non-buffing upper material in the gluing process.
