Abstract

The invention discloses a high-elasticity natural fiber bed core. The high-elasticity natural fiber bed core comprises at least one intermediate layer and a surface layer arranged on the upper surface or the lower surface of the intermediate layer, wherein each surface layer is a non-woven layer consisting of the following components by weight: 15 to 40 percent of low-melting-point fiber and 60 to 80 percent of raw bamboo fiber; the intermediate layer consists of the following components by weight: 60 to 85 percent of bamboo palm fiber and 15 to 40 percent of low-melting-point fiber; the bamboo palm fiber consists of coconut palm fiber and raw bamboo fiber; and the content ratio of the coconut palm fiber to the raw bamboo fiber is (1-4):1. The invention further discloses a preparation method for the natural fiber bed core. The preparation method comprises the following steps: preparing the upper surface layer, the lower surface layer and the intermediate layer respectively; sequentially paving the layers; drying by using a drying oven; performing cold rolling; cooling; cutting; checking; and packaging. According to the natural fiber bed core and the preparation method thereof, the technical problems that the conventional mattress is easy to layer and break, has low elasticity and low air permeability, and is mildewed and verminous are solved.

Description

technical field [0001] The invention relates to a bed core, in particular to a bed core prepared from palm bamboo fiber and a preparation method thereof. Background technique [0002] At present, most of the fiber bed cores are made of traditional coconut palm mattresses. Coconut palm mattresses need to be bonded with a lot of glue. If they are used for a long time, they will cause harm to human health. , and easy to collapse, easy to break, and relatively hard, poor elasticity, narrow range of use, more suitable for hard mattress filling materials. [0003] Publication number is that the patent of CN102174729A discloses a kind of polyester fiber coir palm board, and it comprises three layers, and upper and lower two layers of material are identical, all are to adopt low-melting point two-component skin-core fiber and three-dimensional crimped round hollow fiber; The middle layer material is Low melting point bicomponent sheath core fiber and coir fiber. Although the above...
