PROBLEM TO BE SOLVED: To provide a method of processing for forced feed crimping of biodegradable fiber bundles reducing end breakage of single yarn caused by scraping with forced feeding rollers, and fusion by frictional heating between threads caused by the forced feeding rollers. SOLUTION: The method of processing for forced feed crimping of the biodegradable fiber bundles imparts forced feed crimping to the fiber bundles with single filament fineness of 1.1-6.6 dtex which comprises a biodegradable thermoplastic resin, by setting the single filament fineness (dtex) and the surface roughness (μm) of the forced feeding crimp imparting rollers satisfy following equation (1). Equation (1), the surface roughness (μm) of the forced feeding crimp imparting rollers/the fineness of the single filament (dtex)≤2.5. COPYRIGHT: (C)2003,JPO
