A discussion about influences of factors including temperature,time and solid-liquid ratio on the preparation of cellulose whiskers and an optimization of preparation conditions were made by hydrolyzing absorbent cotton with sulfuric acid(64%,mass fraction). The result shows that the best preparation con-dition is 55 ℃,30 min and 1 :12 g/mL,under this condition,the size of prepared cellulose whiskers has a uniform distribution,the overall length is 1~10 μm and the length-diameter ratios is from 1~10.
