Embodiment 1
[0034] A preparation method of a bamboo waste elastic cushion that fits the pressure distribution of human buttocks is as follows:
[0035] (1) Preparation of bamboo waste elastic unit:
[0036] (1-1) Screen out bamboo wastes with a width of 2 mm and a developed length of 150 mm from the bamboo wastes, and dry them for 24 hours at a temperature of 108±2° C. to obtain dried bamboo yellow fibers;
[0037] (1-2) Fully disperse and mix the dried bamboo yellow fiber and the opened low-melting point fiber according to the mass ratio of 50%, 60%, 70%, 80%, and 90%, to obtain a bamboo waste-based mixture;
[0038] (1-3) Weighing 18 g of the bamboo waste-based mixture and putting it into a metal mold with a side length of 60 mm, heating at 150° C. under normal pressure for 20 minutes, cooling naturally and post-processing to obtain the elastic unit of bamboo waste;
[0039] (2) bamboo waste elastic cushion preparation comprises the following steps:
[0040] (2-1) The elastic unit bod...

[0047] A preparation method of a bamboo waste elastic cushion that fits the pressure distribution of human buttocks is as follows:
[0048] (1) Preparation of bamboo waste elastic unit:
[0049] (1-1) Screen out bamboo wastes with a width of 5 mm and a developed length of 200 mm from the bamboo wastes, and dry them for 24 hours at a temperature of 108 ± 2° C. to obtain dried bamboo yellow fibers;
[0050] (1-2) Fully disperse and mix the dried bamboo yellow fiber and the opened low-melting point fiber according to the mass ratio of 50%, 60%, 70%, 80%, and 90%, to obtain a bamboo waste-based mixture;
[0051] (1-3) Weigh 22 g of the bamboo waste-based mixture and put it into a metal mold with a side length of 60 mm. After heating at 180° C. under normal pressure for 15 minutes, cool naturally and post-process to obtain the elastic unit of bamboo waste.
[0052] (2-1) The elastic unit body of bamboo waste obtained in different mixing ratios is divided into five grades according...
Embodiment 3
[0059] A preparation method of a bamboo waste elastic cushion that fits the pressure distribution of human buttocks is as follows:
[0060] (1) Preparation of bamboo waste elastic unit:
[0061] (1-1) Screen out bamboo wastes with a width of 4 mm and a developed length of 180 mm from the bamboo wastes, and dry them for 24 hours at a temperature of 108±2° C. to obtain dry bamboo yellow fibers;
[0062] (1-2) Fully disperse and mix the dried bamboo yellow fiber and the opened low-melting point fiber according to the mass ratio of 50%, 60%, 70%, 80%, and 90%, to obtain a bamboo waste-based mixture;
[0063] (1-3) Weigh 20 g of the bamboo waste-based mixture and put it into a metal mold with a side length of 60 mm. After heating at 160° C. under normal pressure for 18 minutes, cool naturally and post-process to obtain the elastic unit of bamboo waste.
[0064] (2-1) The elastic unit body of bamboo waste obtained in different mixing ratios is divided into five grades according to ...
