Pure bamboo fiber mattress and manufacturing method thereof

A method for manufacturing a pure bamboo fiber mattress, comprising the following steps:

• 1. trimming and cleaning bamboo comprising using fresh bamboo of 1-2 years old, removing branches and bamboo leaves of the bamboo, and cleaning an outer surface of the bamboo;
• 2. sawing comprising using a circular saw to saw the bamboo into a bamboo tube having a length of 2-4 m;
• 3. splitting comprising using a splitting machine to hit and split the bamboo tube into pieces, dividing the bamboo tube into 8-16 parts in a cross-sectional direction of the bamboo tube to form bamboo strips each having a width of 1-2 cm;
• 4. slicing the bamboo strips comprising using a slicer to slice the bamboo strips into three types of long bamboo laminations as a surface layer, a transition layer and a core layer;
• 5. weaving comprising putting the long bamboo laminations into a weaving machine, wherein a gap of 5 mm is kept between every adjacent two of the long bamboo laminations to form a bamboo mesh;
• 6. softening comprising using an alkaline solution to boil the bamboo mesh for 2-3 hours;
• 7. directional fiber opening comprising using a directional fiber opening machine to perform a directional fiber opening treatment for the softened bamboo mesh to obtain three types of bamboo mesh fabric of the surface layer, the transition layer and the core layer;
• wherein, the bamboo mesh fabric of the surface layer is defined as a first bamboo mesh fabric, the bamboo mesh fabric of the transition layer is defined as a second bamboo mesh fabric, and the bamboo mesh fabric of the core layer is a defined as third bamboo mesh fabric;
• 8. dry cleaning, drying and removing dust comprising putting the bamboo mesh fabric into a dry cleaning machine to remove impurities on a surface of a fiber;
• after drying the surface of the fiber naturally at room temperature, the bamboo mesh fabric being dried in a dryer at 50° C.-70° C.;
• 9. stacking comprising laying the surface layer, the transition layer, the core layer, another transition layer and another surface layer in sequence from top to bottom to obtain a blank;
• wherein
• the surface layer is formed by laying 3-5 layers of the first bamboo mesh fabric, the surface layer having a thickness of 6-10 mm;
• the transition layer is formed by laying 3-8 layers of the second bamboo mesh fabric, the transition layer having a thickness of 20-32 mm;
• the core layer is formed by laying 3-8 layers of the third bamboo mesh fabric, the core layer having a thickness of 40-60 mm;
• 10. sewing and packing comprising using a bamboo fiber rope for multi-layer dense sewing of the blank, cutting and edge banding, packing and storing.
