Abstract

The invention provides flame-retardant anti-dripping high-moisture-permeability artificial leather and a preparation method thereof. The TPU (thermoplastic polyurethanes) artificial leather is formed by compounding of a TPU foaming layer and a TPU leather film face layer on a flame-retardant base cloth layer, wherein the leather film face layer and the foaming layer as well as the foaming layer and the base cloth layer are adhered through a low-melting-point TPU adhesion layer. Each of the leather film face layer, the foaming layer and the adhesion layer realizes film formation by casting after phosphorus-nitrogen intumescent flame retardants and anti-dripping agents are doped into TPU resin particles, and a protein ultrafine powder pore-foaming agent is especially doped into the leather film face layer and the adhesion layer to improve moisture permeability. The high-moisture-permeability artificial leather for clothes is long in flame retardation time, generates no or few molten drops in combustion and can be applied to clothing articles such as clothes, shoes, caps, gloves and the like and used as a fabric for high-temperature-resistant protection garments.

Description

technical field [0001] The invention relates to the technical field of artificial leather, in particular to a flame-retardant, droplet-resistant, high-moisture-permeable thermoplastic polyurethane garment leather and a manufacturing method thereof. Background technique [0002] Polyurethane synthetic leather (PU leather) has the advantages of high strength, wear resistance, cold resistance, breathability, aging resistance, solvent resistance, soft texture, beautiful appearance, and easy processing. It is an ideal imitation leather product to replace natural leather and is widely used in clothing. , shoes and hats and other apparel fabrics. Among them, solvent-based polyurethane PU leather is mainly processed by dry and wet processing of polyurethane solution (organic solvent or water) and woven fabrics, non-woven fabrics, knitted flannelettes, etc. Whether it is PU artificial leather produced with organic solvents or water as a solvent, the production process is relatively ...
