Abstract

The invention relates to an artificial leather and a manufacturing method thereof. The manufacturing method of the artificial leather comprises: providing thermoplastic polyurethane (TPU) ester pellets; heating and melting the thermoplastic polyurethane (TPU) ester pellets; melt-blowing the melted thermoplastic polyurethane to form a first thermoplastic polyurethane fiber net layer; thermoplastic polyurethane, to form a second thermoplastic polyurethane fiber web layer on the first thermoplastic polyurethane fiber web layer, and form a multi-layer thermoplastic polyurethane (TPU) fiber web layer structure; and heat press the multi-layer thermoplastic polyurethane fiber web Layer structure to make artificial leather.

Description

technical field [0001] The invention relates to an artificial leather and a manufacturing method thereof. Background technique [0002] Existing manufacturing of multi-layer artificial leather generally adopts a variety of different processes, and some processes require the use of solvents, such as impregnating resin or fiber dissolution. However, the above manufacturing method not only makes the manufacturing process more complicated, but also does not meet the requirements of environmental protection. [0003] Therefore, it is necessary to provide an innovative and progressive environmentally friendly artificial leather and its manufacturing method to solve the above-mentioned deficiencies in the prior art. Contents of the invention [0004] The present invention relates to an artificial leather. In one embodiment, the artificial leather includes: multiple layers of thermoplastic polyurethane (TPU) fiber net layers, and the fiber fineness of these thermoplastic polyure...
