英文摘要：

The surface of natural fibres were analyzed by scanning electron microscopy （SEM） and optical microscope. It was found that the surface of natural fibres have various forms of thorn knot, whose structure has unique application value. The longitudinal shape, formation and function of fibre thorn knot were studied to provide bionic basis for the production of chemical fibres.
