Abstract

The invention discloses solvent-free ultrafine fiber mirror synthetic leather. The solvent-free ultrafine fiber mirror synthetic leather comprises an ultrafine fiber Base fabric layer as well as a first sizing agent layer, a second sizing agent layer and a bonding layer which are transferred onto the ultrafine fiber Base fabric layer through mirror release paper, wherein the bonding layer is bonded with the ultrafine fiber Base fabric layer. A preparation method comprises steps as follows: step 1, the mirror release paper is coated with a prepared sizing agent for the first sizing agent layer and the sizing agent is dried; step 2, the first sizing agent layer is coated with a prepared sizing agent for the second sizing agent layer, and the sizing agent is dried; step 3, the second sizing agent layer is coated with a prepared sizing agent for the bonding layer, and the second sizing agent layer is attached to the ultrafine fiber Base fabric layer and dried; step 4, the mirror release paper is removed, and the synthetic leather is obtained. The production process is simple, the production cost is low, and the crease-free and environment-friendly mirror synthetic leather produced with the process and having good rebound effect and physical property can be widely applied to shoe leather, bag leather, decoration and the like.

Description

technical field [0001] The invention relates to a kind of synthetic leather, more specifically, relates to a kind of non-solvent superfine fiber mirror surface synthetic 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. [0003] A plastic product that simulates the composition and structure of natural leather and can be used as a substitute for it. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Its front and...
