Water-repellent oil-repellent superfine fiber synthetic leather and preparation method thereof

Abstract

The invention discloses water-repellent oil-repellent superfine fiber synthetic leather and a preparation method thereof. The preparation method comprises the following steps of: (1) coating a chemical substance containing a water-repellent oil-repellent group on the surface of the superfine fiber synthetic leather; and (2) drying the product obtained in the step (1) through plasma gas, thus obtaining the water-repellent oil-repellent antifouling polyurethane superfine fiber synthetic leather. The prepared superfine fiber synthetic leather has excellent water-repellent oil-repellent effects and the characteristic of washing resistance. In addition, the preparation method has the advantages of low energy consumption and simple process.

Description

technical field

[0001] The invention relates to a polyurethane superfine fiber synthetic leather and a manufacturing method thereof. Background technique

[0002] With the increasing application fields of polyurethane microfiber synthetic leather (abbreviated as microfiber leather), the requirements for its water-repellent, oil-repellent and anti-fouling functions are becoming more and more intense.

[0003] Whether the material has the function of water repellency, oil repellency and antifouling is whether water or oil can wet the surface of the solid, and there are two ways to judge whether the water or oil can wet the solid surface: one is by comparing the surface of the solid Critical surface tension and interfacial tension between water or oil and solid. When the critical surface tension of solid surface is less than the surface tension between water or oil and solid, water or oil cannot wet the surface of the solid, indicating that the solid has water and oil repellenc...
