The invention discloses a bamboo
fiber composite material bed core and a preparation method thereof, the bamboo
fiber composite material bed core comprises a
surface layer, a core layer and a protective layer, the
surface layer is arranged on the upper surface of the core layer, the protective layer is arranged on the lower surface of the core layer, the
surface layer is composed of 40-60% of
polylactic acid bi-component
low melting point fiber, 15-30% of spinnable bamboo fiber and 20-30% of
phase change fiber, and the protective layer is arranged on the lower surface of the core layer. The core layer is composed of 30-45% of
polylactic acid bi-component low-melting-point fiber, 30-60% of bamboo fiber crude fiber and 20-30% of antibacterial fiber, and the protective layer is composed of 45-55% of
polylactic acid bi-component low-melting-point fiber, 20-30% of non-woven bamboo fiber and 20-30% of Shuelan fiber. The problem that an existing mattress is poor in heat preservation effect is solved, the
moisture absorption and dissipation performance cannot be affected, the antibacterial fibers in the core layer are used for improving the bacterium resistance and bacteriostasis of the mattress, and the comfortable elastic fibers of the
protection layer further guarantee the constant-temperature performance; the mattress disclosed by the invention has multiple functions of
moisture absorption,
perspiration,
antibiosis, deodorization, constant temperature and
static electricity prevention at the same time.
