PURPOSE: An environment-friendly brush is provided, which can embody elasticity or suitable flexibility by micro sized precision-machining. CONSTITUTION: An environment-friendly brush comprises a plurality of brushes(21) arranged in the specified type. The brushes are manufactured by extruding or injecting a biodegradation property synthesis polymer melting liquid selected among PCL(polyε-caprolactone), PLA(polylactic acid), PCL(polyε-caprolactone), PLA(polylactic acid), diol/diacid aliphatic polyester, PG(polyglycolic acid), polyphosphate ester, and polyphosphazene. |
