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

Abstract

The invention discloses a composite natural fibre bed core, which comprises at least one interface layer and surface layers equipped on the upper surface or lower surface of the interface layer, and the surface layer is a nonwoven layer which is composed of the following components by weight percent: low melting point fiber 15-40% and fibriia 60-85%, and the interface layer is composed of the following components by weight percent composite natural fibre 60-85% and low melting point fiber 15-40%, and the composite natural fibre is composed of coconut fiber, bamboo fibril and fibriia, and the ratio between coconut fiber: bamboo fibril: fibriia is 1:1:1-3:2:1. The invention also discloses a preparation method of natural fibre bed core, which comprises the following steps: respectively preparing each layer containing the up and down surface layer and the interface layer, and then paving in sequence, drying by baking oven, cold rolling, cooling, cutting, examining and packing. The natural fibre bed core and the preparation method solve the technology problems such as easy layering and fracture, less elasticity, bad permeability, mildew and insect generation, etc. in the present mattress.

Description

technical field [0001] The invention relates to a bed core, in particular to a bed core prepared by using composite natural fibers 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. Althoug...
