Fiber bed core and preparation method thereof

Abstract

The invention discloses a fiber bed core. The 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 which comprises the following components in percentage by weight: 15-40% of low melting point fibers and 60-85% of raw bamboo fibers; and the middle layer comprises the following components in percentage by weight: 60-75% of hemp fibers and 25-40% of low melting point fibers. The invention further discloses a preparation method of the 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 fiber bed core. Through adoptions of the fiber bed core and the preparation method thereof disclosed by the invention, technical problems of easiness for layering and cracking, insufficient elasticity, poor ventilating property, mildews, insects, uneasiness for conveying and the like in the current mattres are solved.

Description

technical field [0001] The invention relates to a fiber bed core, in particular to a mattress filling core prepared by using bamboo fiber and hemp fiber and a preparation method thereof. Background technique [0002] At present, most of the filling cores of fiber mattresses are made of traditional coconut palm mattresses. Coconut palm mattresses need to be bonded with a large amount 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...

AI Technical Summary

Problems solved by technology

Although the above-mentioned polyester fiber coconut palm board solves the problems of using glue and hard quality of the coconut palm mattress, the coconut palm fiber itself is prone to moisture, mildew, insect deterioration, poor moisture absorption and antibacterial performance, and long-term use is harmful to human health. Moreover, the mattress is easily deformed and heavy, which brings great inconvenience to handling and transportation.

[0004] Combining hemp fiber and low-melting fiber to produce mattresses can solve both the problems caused by palm fiber and the use of glue, but because the hemp fiber is thin and soft, the applicant found in the research that The addition amount will directly affect the strength and elasticity of the mattress; the low-melting fiber is used as a binder, and the applicant finds that the addition amount is also very important. If the addition is too much, the mattress will be too hardened and the elasticity will be poor. If the addition amount is too small It will not be able to play a good bonding role, affect the strength, and easy to delaminate

Although some documents also disclose the addition of some low-melting-point fibers and hemp fibers respectively, on the one hand, the low-melting-point fibers and hemp fibers disclosed in these documents have a wide range. Obviously, this prior art has not considered low-melting-point fibers, hemp fibers, The effect of the addition of hemp fiber on the performance of the mattress; on the other hand, because the hemp fiber and the low-melting point fiber cooperate with each other, in view of the fact that the properties of the hemp fiber and the low-melting point fiber are quite different from those of the corresponding materials used in some literatures, Thereby those skilled in the art cannot know according to the above-mentioned documents how to match the low-melting point fiber and the hemp fiber and how to make a product whose performance meets the requirements

In terms of structure, most of the current mattresses adopt a single-layer structure. In order to achieve a good use effect of the mattress, it needs to have a variety of properties. For example, while ensuring strength and elasticity, it also needs good air permeability and comfort. Well, if you adopt a single-layer structure, you will not be able to take care of it, because to achieve sufficient strength, you must reduce the porosity, which will affect the air permeability. Good air permeability will affect the strength, and the structure will be loose if the air permeability is good. The middle of the mattress The hard fibers are easy to tie out and affect the comfort
