FLAME-RETARDANT MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a flame-retardant material having flamer retardancy without imparting a flame retardant. SOLUTION: The flame-retardant material is constituted of a spun-bonded nonwoven fabric which comprises a polylactic acid-based polymer and has a flame retardancy of≥26 oxygen index measured by JIS K 7201. The spun- bonded nonwoven fabric is preferably obtained by melt-spinning the polylactic acid-based polymer having 40-80 g/10 min melt flow rate. The crystallinity of a filament constituting the spun-bonded nonwoven fabric is preferably 10-20 wt.%. COPYRIGHT: (C)2004,JPO
