Abstract

The invention discloses suede nap ultra-soft protein leather which comprises a suede nap base fabric, a wet base layer and a dry veneering layer, wherein raw material ingredients of the wet base layerinclude ultra-soft polyurethane resin, soft polyurethane resin, N,N-dimethyl formamide, a cell regulation assistant, color paste, ramie fibers, chitin powder, a dispersing agent and a waterproof assistant; and the dry veneering layer is formed by a surface material layer and a bottom material layer. The suede nap ultra-soft protein leather disclosed by the invention is prepared by ramie fiber processing, wet base layer preparation, dry veneering layer preparation, finished product leather preparation and post-stage processing; the wet ultra-thin polyurethane resin of the suede nap ultra-softprotein leather contains a special material, and the special material is exchanged with water in the solidifying and washing process to form cells, so that the product is soft and air-permeable; and by combining the advantages of a suede nap base fabric, when the suede nap ultra-soft protein leather is machined into a garment, the garment is comfortable in touch sense, soft, exquisite, wrinkle-resistant, overhung and crisp and a user is extraordinary in demeanour.

Description

technical field [0001] The invention belongs to the field of synthetic leather, in particular to a suede supersoft protein leather. Background technique [0002] Natural leather is widely used in the production of daily necessities and industrial products due to its excellent natural characteristics. However, with the growth of the world population, the human demand for leather has doubled, and the limited amount of natural leather has long been unable to meet this demand. In order to solve this contradiction, scientists began to research and develop artificial leather and synthetic leather decades ago to make up for the deficiency of natural leather. The research history of more than 50 years is the process of artificial leather and synthetic leather challenging natural leather. [0003] The composition and structure of synthetic leather and plastic products that can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, a...
