PURPOSE:To obtain a nonwoven fabric, having high strength and bacterial barrier properties and further hygroscopicity and printability by heat bonding a netlike fibrous web composed of a polyethylenic polymer and a polyvinyl alcoholic polymer all over. CONSTITUTION:This netlike nonwoven fabric is obtained by carrying out the flash spinning of high-density polyethylene (A) and a polyvinyl alcoholic polymer (B) so as to satisfy 1<=BX100/[A+B]<=25 (A and B are respectively wt.%), providing netlike fiber, containing the polyvinyl alcoholic polymer finely dispersed in the high-density polyethylene and having at least 10m<2>/g specific surface area, forming the netlike fiber into a web and then subjecting the formed web to hot-pressing treatment all over with a hot calender. |
