 note = {Drawing behavior. flow drawling and neck drawing, was studied for i-PP fibers in CO2 laser drawing system, and the characteristics of drawing fibers were analyzed. In a certain drawing condition, flow drawing of PP was possible up to draw ratio 19.5. Neck-drawing was performed from draw ratio (DR) 4 to 12. Simultaneous development of structure and properties were observed with increasing draw ratio. DR 10 and 12 were visibly white and their SEM images provide evidences of fibril formation.The highest tensile strength of 910 MPa and Youngk modulus of 8.8 GPa were obtained by laser-heated neck-drawing., Article, 先進ファイバー工学研究教育拠点研究成果報告書 11: 112-113(2005)},
