Non-woven material comprising polymer fibers using a mixture containing an amphiphilic block copolymer, as well as the manufacture and use these

摘要

This invention as a phase conversion medicine for blend manufacturing used the blend which includes parents crocking characteristic block copolymer, it possesses high expansion characteristic, it regards the production, and these productions and use of the nonwoven fabrics material which includes the polymer fiber. As for the said nonwoven fabrics material, being the nonwoven fabrics material which includes the polymer fiber of the blend which at least consists of the block copolymer of 1 where it becomes the polymer of the further 1 kinds which at least do not have the miscibility of the polypropylene, or the polypropylene of 1 kinds, and the phase conversion medicine for blend manufacturing kinds, the said block copolymer, at least hydrophobic block of 1 where essentially it consists of the isobutene unit kinds (A), and the hydrophilic block which consists of the oxy alkylene unit essentially includes (B).
