Abstract

The invention discloses a memory foam material containing a natural fiber and application of the memory foam material. The product comprises a memory foam material body, wherein the memory foam material body contains the natural fiber of which the content is 15-80 percents of the total volume of the memory foam material body. The natural fiber is one or more of bamboo fiber, hemp fiber, wood fiber, chitosan fiber, natural palm fiber and natural desiccated coconut. The natural fiber replaces the most of space occupied by air bubbles originally, so that the gas phase volume fraction of the foam body is reduced, and the thermal conductivity is increased; thus, the heat dissipation capacity and permeability of the product are greatly improved, and the problems of low thermal conductivity and poor heat dissipation of the traditional memory foam are solved. The higher the content of the natural fiber is, and the higher the heat dissipation capacity and permeability of the prepared memory foam are.

Description

Technical field [0001] The invention relates to a high molecular polymer material, in particular to a memory foam material containing natural fibers and its use. Background technique [0002] The memory foam is composed of many small particles. After contacting the body temperature, it will naturally soften and sink with the body shape, and evenly distribute the compressed area, so that the human body can be comfortably supported. Memory foam is a functional polymer material and a new branch of polymer material research, development and application. With the deepening of the understanding of polymer structure and characteristics, and the development of polymer synthesis technology, it has become a reality that polymer materials can obtain the expected structure and performance through molecular design. [0003] Memory foam is the use of modern polymer physics and polymer synthesis and modification technology to carry out molecular combination and modification of general polymer ma...
