A kind of preparation method of high-strength packaging chemical fiber paper

Abstract

The invention belongs to the technical field of a novel paper making industry, and provides a preparing method of high-strength wrapping chemical fiber paper. The method is characterized by comprising the steps of coating the surface of chemical fiber with fatty acid salt to make hydrophily and wettability of the fiber improved, and then adopting a laser surface coating method to coating the surface of the chemical fiber with acrylic resin so as to form an even, orderly and compact thin film on the surface of the chemical fiber; the strength of the chemical fiber paper is improved during paper making, the problems are solved that average chemical fiber has a smooth surface, and is poor in wettability of water and low in surface activity and ideal combination is hard to achieved among different units of fiber, and the shortcomings are overcome that fiber is difficult to disperse and the combination strength is low among different units of paper fiber during mixed paper making with chemical fiber and other fiber raw materials. Besides, the application space of the chemical fiber is expanded. The preparing method of the high-strength wrapping chemical fiber paper is simple in operation, environmentally friendly in the process, low in cost and capable of achieving scale production.
