Light-color bamboo bundle, recombined bamboo and preparation method and application of light-color bamboo bundle and recombined bamboo

The invention relates to the technical field of new materials, in particular to a light-color bamboo bundle and a preparation method thereof, and a recombined bamboo and a preparation method and application thereof. The light-color bamboo bundle is characterized in that after an original bamboo bundle is subjected to alkali liquor splitting and hydrogen peroxide bleaching in sequence, at least 10% of polysaccharide in the original bamboo bundle is removed, and the light-color bamboo bundle has the whiteness of at least 29.0%. The light-color bamboo bundle provided by the invention can be used for preparing the recombined bamboo, the static bending intensity of the prepared recombined bamboo reaches 129MPa, the elastic modulus reaches 14064MPa, the recombined bamboo reaches a 120Eb superior product, and the mildew-proof grade can reach 0-1 grade. 本发明涉及新材料技术领域，特别涉及一种浅色竹束及其制备方法、重组竹及其制备方法和应用。一种浅色竹束，其特征在于，所述浅色竹束由原始竹束依次经过碱液拆分和双氧水漂白后，所述原始竹束中至少10％的多糖被去除且所述浅色竹束具有至少29.0％的白度。本发明所提供的浅色竹束可用于制备重组竹，所制备得到的重组竹静曲强度达到129MPa，弹性模
