Aqueous baodao sueded microfiber leather and preparation process thereof

Abstract

The invention discloses a preparation process of aqueous baodao sueded microfiber leather, and the preparation process comprises the following steps: aqueous baodao fiber is prepared by treatment of raw materials before spinning, blending yarn spinning and fiber post-spinning, a non woven fabric is prepared by a non-weaving process from the aqueous baodao fiber, and the aqueous baodao sueded microfiber leather is prepared by a base cloth processing process from the non woven fabric. The invention also discloses the aqueous baodao sueded microfiber leather prepared by the process. The aqueous baodao sueded microfiber leather can combine the advantages of both a super fiber material and a leather material, and adopts waterborne polyurethane to further meet the environmental protection needs, meanwhile reduction of the cost and shortening of the process time, the prepared finished product has dense structure, soft hand feeling, excellent mechanical properties and other physical properties.

Description

technical field [0001] The invention relates to a suede microfiber skin and, in particular, to a preparation process of a suede microfiber skin. Background technique [0002] At present, in the shoes, clothing, luggage and other industries, more high-end leather materials are used, but the leather materials are derived from animal leather, and the resources are very limited. Under the premise of vigorously promoting environmental protection and cherishing the environment, microfiber materials have physical properties comparable to leather, and even high-grade microfiber materials have better physical properties than genuine leather materials. Therefore, microfiber materials are recognized by consumers. and favorite. [0003] Although microfiber materials can partially replace leather materials and are widely used in various fields, it is difficult to completely recover the solvents used in the preparation of superfiber materials, and some of the solvents evaporate into the ...
