Abstract

The invention discloses a natural fiber health-care board which consists of a middle layer and a surface layer arranged on the upper surface or the lower surface of the middle layer. The surface layer is a non-woven layer comprising 5 percent to 50 percent of low melting point fibers. The middle layer is a non-woven layer which comprises the following components: bastose and 5 percent to 50 percent of low melting point fibers. In the natural fiber health-care board, the content of the bastose is within the range of 5 percent to 65 percent. The invention also discloses a preparation method of the natural fiber health-care board, which comprises the following steps of: respectively preparing the middle layer and the upper or lower surface layer; then sequentially paving the layers; and preparing the natural fiber health-care board by processes of processing by an oven, cold milling, cooling, cutting, inspecting and packaging. Due to the adoption of the natural fiber health-care board and the preparation method thereof, which are disclosed by the invention, the problem that the existing mattress is easy to affect with damp, mildew, breed worms and deteriorate, is easy to layer and has poor air permeability is solved.

Description

Technical field [0001] The present invention relates to a composite board, in particular to a natural fiber health board prepared from hemp fiber and a preparation method thereof. The natural fiber health board of the present invention can be used as a mattress material, and of course can also be used for other purposes. Background technique [0002] At present, the commonly used coconut palm mattresses use palm fiber as the filling material, and a large amount of glue is used to bond the coconut palm mattresses. Long-term use will cause harm to human health. Moreover, coconut palm mattresses are not only more susceptible to damp, mold, or insect deterioration, easy to collapse, easy to break, but also harder and less elastic, and their use range is narrow, and they are mostly suitable for hard mattresses. [0003] The patent document with the publication number CN201139289Y discloses a health-care mattress, including a mattress body and a jute fiber fabric covering layer covering ...
