The intelligent fibers have an important position and special usefulness in the materials field.In this paper

the train of thought for designing intelligent fibers was reviewed

including bionics

moleculear design and complex technology;the preparing technolegy of intelligent fibers was described

including the direct spinning of intelligent polymer-forming fiber

graft copolymerizion

crosslinking

blending and addition

composite sipinning and hybridization

chemical reaction of polymer as well as post-treatment and so on;it was suggested that the research and development of intelligent fiber should be paid more attention in China.
