Abstract

The invention provides a water-based shoe lining leather bass and a preparation method thereof. The method comprises the following steps of providing a base cloth, coating the base cloth with a coating to obtain a wet bass, and adopting an aqueous solution of a water absorbent for wetting the wet bass to obtain the shoe lining leather bass. The lining leather bass prepared by means of the method has excellent water absorption and air permeability, organic solvents are not used in the whole production and preparation process, a spunlace non-woven fabric is adopted as the base cloth, and the prepared shoe lining leather is soft in hand feeling and high in air permeability.

Description

technical field [0001] The invention relates to the technical field of water-based polyurethane synthetic leather, and specifically discloses a water-based shoe lining and a preparation method thereof. Background technique [0002] At present, most of the leather used for shoe materials in the market are solvent-based products, which are not environmentally friendly, and have problems such as poor moisture permeability and air permeability. Solvent-based products have different degrees of solvent environment during the production process, which has a greater impact on the environment. The shoe lining bass developed by the present invention does not use organic solvents in the whole production and processing process. The materials and processes are environmentally friendly. The body improves the water absorption of the slurry, and the product avoids DMF, toluene, VOC and other harmful volatiles from the source, and the product has good water absorption and air permeability. ...
