Composite health care pad and manufacture method thereof

Abstract

The invention discloses a composite health care pad, which comprises a middle layer, wherein an upper surface layer and a lower surface layer are respectively arranged on the upper surface and the lower surface of the middle layer, a layer of blocking layer is respectively arranged between the middle layer and the upper surface layer and / or between the middle layer and the lower surface layer. The upper surface layer and the lower surface layer are non-woven layers containing 5%-50% low-melting-point fibers, and the middle layer is a non-woven layer containing the following components: fibrilia and 5%-50% of low-melting-point fibers. The blocking layers are non-woven layers containing 5%-100% of fibrilia, and the content of fibrilia in the composite health care pad ranges from 5% to 65%. The invention further discloses a manufacture method of the composite health care pad, which includes the following steps: respectively manufacturing the middle layer, the upper surface layer, the lower surface layer and the blocking layers, sequentially overlaying all the layers, and carrying out procedures including drying in a drying oven, cold rolling, cooling, cutting, inspection and packing. The composite health care pad and the manufacture method thereof solve the problems that the existing mattress can become damp and mildewed easily, can be damaged by worms, is apt to be layered, and is poor in ventilation and inconvenient to use caused by the fact that hard fibers in the middle of the mattress prick out.

Description

technical field [0001] The invention relates to composite materials, in particular to a composite health-care pad prepared from hemp fiber and a preparation method thereof. The composite health-care pad of the invention can be used as a mattress 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 mattress body, wherein the mattress bo...

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
