Abstract

The invention discloses a tatami bed core. The tatami 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/or hemp fibers; and the middle layer comprises the following components in percentage by weight: 5-85% of alpinia fibers, 15-40% of low melting point fibers and the balance of other fibers. The invention further discloses a preparation method of the tatami 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 tatami bed core. Through adoptions of the tatami bed core and the preparation method thereof disclosed by the invention, technical problems of mildews, insects, easiness for layering and cracking, insufficient elasticity, poor ventilating property and the like in a current bed mattress are solved.

Description

Technical field [0001] The invention relates to a bed core, in particular to a tatami bed core and a preparation method thereof. Background technique [0002] At present, most of the bed cores are made of traditional coconut palm mattresses. Coconut palm mattresses need to be glued with a lot of glue. If used for a long time, it will cause harm to human health. Coconut palm mattresses are not only more susceptible to damp, mold, and insect deterioration. Moreover, it is easy to collapse and break, and it is harder and less elastic, and has a narrow range of use. It is mostly suitable for hard mattress filling materials. [0003] The patent with publication number CN102174729A discloses a polyester fiber coconut palm board, which includes three layers, the upper and lower layers have the same material, and both use low-melting two-component sheath-core fibers and three-dimensional crimped round hollow fibers; the material of the middle layer is Low melting point two-component core-...
