This is a technology to treat the fibre surface to make it has nano-crystallization. Its steps are: To use surface treatment nano-powder and disperser mix in remove-ion water, stir them evently to produce nano-surface-treatment solution; to mix lip idol into nano-meeker and stir them to produce nano-meek solution: To use benzophenone mix acetic ethylene lipid to produce nano-photosensitive solution. To put pre-treated fibre in the nano-pholosensitive solution, and irradiate them with ultra violet ray; put these fibres into the nano-treatment solution, adjust pH value after soak them. Then irradiate them with ultraviolet ray again; to treat them with nano-meek solution, washing, drying, produce the surface has nano-crystallization function fibre.
