Crib mattress and manufacturing method thereof

Abstract

The inventional discloses a crib mattress comprising at least one intermediate layer, upper surface layers and lower surface layers, wherein the upper surface layers and the lower surface layers are arranged on the upper surfaces or the lower surfaces of the intermediate layers. Each surface layer is a non-woven layer comprising, by weight, 15-40% of low-fusion-point fibers and 60-85% of polyester fibers. Each intermediate layer comprises, by weight, 60-75% of jute fibers and 25-40% of low-fusion-point fibers. The invention further discloses a manufacturing method of the crib mattress. The manufacturing method includes steps of manufacturing the upper surface layers, the lower surfaces and the intermediate layers and sequentially performing drying in a drying oven, cold rolling, cooling, cutting, checking and packaging. The crib mattress and the manufacturing method thereof solve the technical problems that an existing mattress is easy to mildew and have worms, prone to layering and breaking, poor in elasticity and breathability and not easy to carry, and the like. As the surface layers made of polyester fibers is high in resilience and the intermediate layers made of jute fibers are fine and soft, the crib mattress is quite applicable to infants.

Description

technical field [0001] The invention relates to a bed core, in particular to a bed core specially suitable for babies and a preparation method thereof prepared by using hemp fiber and polyester fiber. Background technique [0002] At present, most of the filling cores of hemp fiber mattresses are made of traditional coconut palm mattresses. Coconut palm mattresses need to be bonded with a large amount of glue. Long-term use will cause harm to human health. Coconut palm mattresses are not only prone to moisture and mold , long worms deteriorate, and are easy to collapse and break, and are hard, poor in elasticity, and have a narrow range of use. They are mostly 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 ...

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
