Abstract

The invention relates to the technical field of leather production, in particular to a production method for crease resistant leather. Soft leather is taken, and the crease resistant leather can be obtained after base coating, tumbling ironing, middle coating, top coating, ironing and drum milling in sequence. In the base coating step, a cationic wax agent and acrylic resin are dissolved in water for spraying treatment; in the tumbling ironing step, a tumbling mill is used for tumbling ironing; in the middle coating step, leather adhesive resin is dissolved in water for spraying treatment; and in the top coating step, acrylic resin ISN, acrylic resin JS, leather cracking resin and leather colorants are dissolved in water for spraying treatment. By the adoption of the production method, the obtained finished leather is resistant to flex and marks are not prone to leave on the leather in the use process of the leather.

Description

[0001] This application is a divisional application of "a production method for crack-resistant leather". The application number of the original application is 201310495083.1, and the filing date is 2013.10.21. technical field [0002] The invention relates to the technical field of leather production, in particular to a production method of twist-resistant leather Background technique [0003] 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. [0004] With the continuous development of leather technology, its bending resistance has been greatly improved, but because the leather is prone to creases during wearing, especially during the wearing of shoes and the use of leather bags, the existing leather resistance Poor bending ability, easy to crease during wearing and use. Contents of the invention [0005] The invention provides a production method of tortuosity-resistant leather. Becaus...
