<p>PURPOSE:To improve the adhesion of bacteria, by using a nonwoven fabric prepared by mutually bonding polyolefinic fibers with high m.p. by the melting of polyolefinic fibers with low m.p. CONSTITUTION:A web consisting of 70-30% of polyolefinic fibers 1 with 50-100 denier having high m.p. and 30-70% of polyolefinic fibers with 3-20 denier having low m.p. is subjected to punching processing to form a long nonwoven fabric 3 brought to such a state that fibers 1, 2 are irregularly entangled with each other and this long nonwoven fabric 3 is wound spirally to form a wound body 4. This wound body 4 is heat-treated by a processing apparatus 5 and cut into a predetermined length to form a bacteria adhering carrier. As the high m.p. polyolefinic resin, there are polypropylene and high density polyethylene and, as the low m.p. polyolefinic resin, there are an ethylene/ propylene copolymer, etc.</p> |
