Abstract

The invention relates to the technical field of leather processing, in particular to a production technology for processing a suede leather material with a silk-like hand feeling by using a waste leather material. The production technology comprises the steps of (1) selecting a material, specifically, adopting a split waste two-layer sheepskin leather material as a leather blank; (2) laminating, specifically, laminating a layer of cloth on the bottom surface of the leather material; (3) spraying, specifically, spraying a layer of a hand feeling agent with the silk-like hand feeling on the surface of the leather material; and (4) attaching a film, specifically, attaching a layer of a nano-film on the surface of the leather blank through a transfer printing mode and obtaining the suede leather material. The production technology for processing the suede leather material with the silk-like hand feeling by using the waste leather material has the advantages that the steps are simple, operation and control are convenient, the quality is stable, the production efficiency is high, the raw material is cheap and easy to obtain, the utilization rate of the leather material is high, the production cost is low, and large-scale industrial production can be realized; and the quality of the produced finished leather material is close to that of a top layer leather material, the additional value of the finished leather material is greatly improved, the application range is wide, and the economic benefit is high.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to a production process for processing waste leather into suede leather with a silky feel. Background technique [0002] Leather is widely used on the surface of daily necessities, such as tables and chairs, sofas, shoe materials, clothing, etc., to add texture, beauty or durability to daily necessities. Leather can be broadly classified into artificial leather and natural leather. Natural leather refers to taking animal fur and drying, cleaning, softening, dyeing, trimming, cutting and other production processes to form a smooth surface and tough texture. [0003] Due to the insufficient fineness and poor glossiness of the existing discarded two-layer sheepskin leather, it can only be used to make the inner lining of the leather material, and cannot be used as the surface layer material of the product. The application range is limited, and the obtained leather material ...
