Natural fiber composite health-care cushion and preparation method thereof

Abstract

The invention discloses a natural fiber composite health-care cushion which comprises a middle layer. A surface layer is arranged on the upper surface or the lower surface of the middle layer. A block layer is arranged between the middle layer and the surface 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. The block layer is a non-woven layer comprising 5 percent to 100 percent of low melting point fibers. In the natural fiber composite health-care cushion, 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 composite health-care cushion, which comprises the following steps of: respectively preparing the middle layer, the upper or lower surface layer and the block layer; then sequentially paving the layers; and preparing the natural fiber composite health-care cushion by processes of processing by an oven, cold milling, cooling, cutting, inspecting and packaging. Due to the adoption of the natural fiber composite health-care cushion 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, has poor air permeability and is discomfortable to use due to protruded hard fibers in the middle of the mattress is solved.

Description

technical field [0001] The invention relates to a composite pad, in particular to a natural fiber composite health care pad prepared from hemp fiber and a preparation method thereof. The natural fiber composite health care pad of the invention can be used as a mattress material or other purposes. Background technique [0002] Coir palm mattress commonly used at present is to adopt palm fiber as filling material, and coconut palm mattress will use a large amount of glue to bond during preparation, if long-term use can cause harm to human health. Moreover, the coconut palm mattress is not only easy to be damp and moldy, or worms to deteriorate, easy to collapse, easy to break, but also hard and poor in elasticity. Its use range is narrow, and it is mostly suitable for hard mattresses. [0003] The patent document whose notification number is CN201139289Y discloses a health-care mattress, including a mattress body and a jute fiber fabric covering layer wrapped outside the mattr...

Problems solved by technology

The patent document whose publication number is CN102174729A discloses a kind of polyester fiber coconut palm board and its preparation method. The coconut palm board in this patent document adopts a three-layer structure, but the addition of low melting point fiber is not made in this document. Obviously, it does not take into account the impact of low-melting fiber additions on air permeability, so those skilled in the art cannot solve the problem of ensuring both air permeability and strength and elasticity according to this prior art; the applicant found that in The needle-punched non-woven layer on the surface can improve the air permeability of the mattress, but because the needle-punched non-woven layer is limited by its process, it cannot be made too thick, so it cannot provide a good barrier to the hard fibers stuck in the middle of the mattress. , once the hard fiber is pulled out, it will make the user very uncomfortable, and the thickness of the surface layer in the patent document with the publication number CN102174729A is adjustable, and there is no problem that the hard fiber cannot be prevented from being pulled out because the surface layer is too thin; Those skilled in the art cannot solve the problem of how to avoid affecting comfort due to sticking out of hard fibers when the thickness of the surface layer is limited according to the prior art
