发明名称 Diskette liner with film and web layers
摘要 A nonwoven media wiping material is provided by a thermal point bonding process which comprises the steps of combining a carded web of predominantly textile-length thermoplastic fibers having a higher melting temperature and a polymeric sheet having a lower melting temperature, and applying heat and pressure to the combination of film and fiber layers through thermal calendering. The polymeric sheet melts and becomes bonded to the carded fibers in discrete points to provide a soft and lofty outer media contacting finish.
