Abstract

The invention relates to the technical field of leather production, in particular to a producing method for stretch-proof leather. The producing method comprises the sequential steps of taking soft leather materials, firstly coating the soft leather materials, drying the soft leather materials in a suspension mode, polishing the soft leather materials, lustering the soft leather materials and spraying color on the soft leather materials. Thus, the stretch-proof leather can be manufactured. In the first coat step, burned black wax and soft casein acrylic resin are dissolved into water to carry out roller coating treatment. In the polishing step, a polishing machine is used for polishing the soft leather materials. In the lustering step, a tumbling mill is used for lustering the soft leather materials. The stretch-proof leather obtained in the producing method is strong in stretch resistance and not prone to deforming in a using process.

Description

Technical field [0001] The invention relates to the technical field of leather production, in particular to a method for producing stretch-resistant leather. Background technique [0002] Leather is a commonly used material in daily life, and people use it in all aspects of clothing, hats, and furniture making. [0003] With the continuous development of leather technology, its resistance performance has been greatly improved, but because the leather is easily deformed during wearing, especially when wearing shoes and purses, the existing leather is resistant to stretching. Poor ability, easy to deform during wearing and use. Summary of the invention [0004] The present invention provides a method for producing stretch-resistant leather. Because a special process formula is adopted in the base drawing process, the relevant technical parameters are strictly controlled in the production through the coordination of the polishing machine and the roller polishing machine, so the produc...
