Abstract

PURPOSE: To obtain a fibrous material having irregular weak spots in the long direction of the fiber bundle, by bending and bringing an undrawn thermoplastic filament bundle into contact with hot friction bodies, by drawing at a draw ratio below the natural draw ratio, and by heat shrinking the bundle at a restricted shrinkage.
CONSTITUTION: The undrawn thermoplastic filament bundle Y(multifilaments, tow or subtow), wherein the S-S curve has no monotonous incnease and a constant tension part or a decreasing tension part with increasing elongation, is bent and brought into contact with the one or two or more friction bodies 15 and 16 at a specific temperature selected from the propenties of the bundle, drawn at a draw ratio below the natural draw ratio (the draw ratio at which the tension reaches the point B the same as the primary yield point D of the monotonous increase zone of the S-S curve), and shrunk at a restricted shrinkage to give a fiber bundle wherein thick parts remain randomly in the long direction or lateral direction of the bundle 20.
