Abstract
The object of the present invention is to provide a monofilament which has sufficient mechanical strength to be practically used also as a string for rackets and which is excellent in workability. Disclosed is a monofilament which is formed by extruding a material prepared by blending mainly a polylactic acid type polymer (A) and an aliphatic polyester (B) other than polylactic acid, and drawing the extruded material. This could be used as a racket string which has a tenacity-elongation curve similar to that of natural gut and is excellent in water resistance and heat resistance.
