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 production method of stretch-resistant leather. Background technique [0002] Leather is a material commonly used in daily life. It is used in various aspects such as dressing and hats, furniture making and so on. [0003] With the continuous development of leather technology, its resistance has been greatly improved, but because leather is easily deformed during wearing, especially during the wearing of shoes and the use of leather bags, the existing leather is resistant to stretching. The ability is poor, and it is easy to deform during wearing and use. Contents of the invention [0004] The invention provides a production method of stretch-resistant leather. Due to the use of a special process formula in the base map flow, through the coordination and cooperation of the polishing machine and the roller polishing machine, the relevant technical parameters are st...
