摘要
PURPOSE: To provide a sheath-core type composite short fiber eliminating the waxy touch of an ethylenic polymer because of having a specific ethylenic copolymer in the sheath part, having a small fineness and a high strength, and suitable for a hot-adhesive non-woven fabric due to the highly oriented fiber having a low thermal stress. ;CONSTITUTION: A sheath-core type composite short fiber is characterized in that the sheath part and the core part of the fiber comprise a propylene- copolymerized ethylenic polymer and a propylenic polymer, respectively, and that the sheath part/core part composite weight ratio is 3/1 to 1/3.;COPYRIGHT: (C)1995,JPO
