Natural fiber bed core and preparation method thereof

Abstract

The invention discloses a natural fiber bed core. The natural fiber bed core comprises at least one middle layer and a surface layer which is arranged on the upper surface or the lower surface of the middle layer, wherein the surface layer is a non-woven layer prepared by the following components in percentage by weight: 15-40% of low melting point fibers and 60-85% of hemp fibers; the middle layer comprises the following components in percentage by weight: 60-85% of bamboo palm fibers and 15-40% of low melting point fibers; the bamboo palm fibers comprise coconut palm fibers and raw bamboo fibers; and the content ratio of the coconut palm fibers and the raw bamboo fibers is 1-4:1. The invention further discloses a preparation method of the natural fiber bed core; and the preparation method comprises the following steps: respectively preparing each layer including an upper surface layer, a lower surface layer and the middle layer; laying the upper surface layer, the lower surface layer and the middle layer in sequence; drying the upper surface layer, the lower surface layer and the middle layer in a drying box; and coldly rolling, cooling, cutting, inspecting and packaging the upper surface layer, the lower surface layer and the middle layer to obtain the natural fiber bed core. According to the invention, through adoptions of the natural fiber bed core and the preparation method thereof, technical problems of easiness for layering and cracking, insufficient elasticity, poor ventilating property, mildews, insects and the like in the current mattress 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...

AI Technical Summary

Problems solved by technology

Although the above-mentioned polyester fiber coconut palm board solves the problem of using glue and hard quality of the coconut palm mattress, the coconut palm fiber itself is susceptible to moisture, mildew, and long-term insect deterioration. Long-term use is harmful to human health, and the mattress is easily deformed, and the air permeability and Elasticity is also poor
