Fiber bed core with good elasticity and preparation method thereof

Abstract

The invention discloses a fiber bed core with good elasticity which comprises at least one intermediate layer and surface layers arranged on the upper surface or the lower surface of the intermediate layer; the surface layers comprise the following components in percentage by weight: 15-40 percent of low-melting point fiber and 60-85 percent of polyester fiber; the intermediate layer comprises the following components in percentage by weight: 60-85 percent of brown hemp fiber and 15-40 percent of low-melting point fiber, wherein the brown hemp fiber consists of coconut fiber and fibrilia in ratio of (1-4):1. The invention also discloses a preparation method of the fiber bed core, which comprises the following steps of: respectively preparing all the layers, i.e. the upper surface layer, the lower surface layer and the intermediate layer, then paving all the layers in sequence and preparing the fiber bed core through the baking, cold-milling, cooling, cutting, inspecting and packaging processes. The fiber bed core and the preparation method thereof have the benefits that the technical problems of easiness in layered fracture, insufficient elasticity, bad air permeability, mustiness and insects existing in the existing bed mattress are solved; and due to the content ratio of the coconut fiber to the brown hemp fiber, the fiber bed core has better elasticity and certain hardness; and fiber bed core is particularly suitable for middle-aged and elderly people.

Description

technical field [0001] The invention relates to a bed core, in particular to a bed core with good rebound performance and certain hardness prepared by composite fibers and a preparation method thereof. Background technique [0002] At present, most of the palm 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. Long worms deteriorate, and are easy to collapse and break, and are relatively hard, poor in elasticity, and have a narrow range of use. They are mostly suitable as filling materials for hard mattresses. [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 m...

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
