Preparation method of palm fibril nonwoven sound absorption material
2015
The invention relates to a preparation method of a palm fibril nonwoven sound absorption material. The palm fibril nonwoven sound absorption material comprises at least one palm fibril nonwoven material layer, wherein the palm fibril nonwoven material layer comprises palm hollow fibrils, and the hollowness of the palm hollow fibril is greater than or equal to 45 percent. By adopting the method, the problems of the prior art that the palm fibers are hardly used and the raw materials are wasted can be solved; moreover, the biological degradability problem of the sound absorption material is solved, and an excellent sound absorption effect also can be realized.
