CONJUGATE FIBER HAVING LOW-TEMPERATURE PROCESSABILITY, NONWOVEN FABRIC AND FORMED ARTICLE USING THE CONJUGATE FIBER

摘要

while having the cold workability, and is also inhibited contraction, with good thermal adhesive, is further passing the card at the time of processing a non-woven fabric polarity fairness excellent, provides composite fibers which have bee kiseong the quality of the fiber to obtain a satisfactory nonwoven fabric. In addition, a low-temperature workability is excellent, having a bee kiseong, provides a good texture and non-woven fabric molded body. A melting point of 70 ~100 ethylene - olefin copolymer and a second component comprising at least 75 mass%, the second component comprising a crystalline polypropylene, a composite fiber made by configuring the parallel section, In the fiber cross section perpendicular to the fiber axis, the first component accounts for 55-90% of the fiber periphery, the boundary between the first component and the second component towards the first component side, and the curve that is curved in a convex and, the first component and the second component and the area ratio (first component / second component) is 70 / 30-30 / composite fibers in a range of 70; Non-woven fabric treated to the composite fiber nonwoven fabric obtained; And. Molded product obtained using the composite fibers ;
