英文摘要：

The goal of this research is to provide theoretical basis for developing lotus fiber fabric. An elementary study on the mechanical properties of lotus fiber is carried out, including the single tensile properties, the elastic properties under constant load and friction properties. The conclusion shows that the initial modulus of lotus fiber is 146.81 cN/dtex, and is superior to cotton, wool and silk, and is close to ramie; the breaking tenacity of lotus fiber is 3.44. cN/dtex, and is superior to wool, and is close to cotton and silk, and is next to ramie; the elongation at break is 2.75 %, and is close to ramie, and is smaller than cotton, wool and silk. Under small stress, lotus fiber has good elasticity; the static and dynamic friction factors of lotus fiber are 0. 554 1 and 0. 320 3 respectively, which shows that lotus fiber is unsmooth fiber.
