The invention discloses a method for preparing natural color bamboo fiber high-water absorption lining paper for production of hygienic products. According to the method, bamboo is adopted as a raw material, and with the combination of physical and chemical methods, a product which is excellent in comprehensive quality and small in environment pollution is prepared. The physical property indexes of the natural color bamboo fiber high-water absorption lining paper are that the longitudinal tensile index is 12-15N-m / g, the transverse tensile index is 3-5N-m / g, the longitudinal wet tensile strength is 30-50N / m, the transverse wet tensile strength is 10-20N / m, the transverse water-absorbing quality is 45-65mm / 100s, the fixed quantity is 10-40g / m<2>, the whiteness is 35-50% ISO, the pentosan is 8% or less, the ash content is 1.0% or less, the bulkiness is 5.5-6.5cm<3> / g, the softness is 250mN or less, the bacteriostasis rate of staphylococcus aureus and escherichia coli is 99% or above, and the bacteriostasis rate of candida albicans is 98% or above.
