High speed method of making plastic film and nonwoven laminates |
摘要 |
Laminates of thermoplastic films and nonwoven fibrous webs are made at high speeds on the order of about 700 fpm to about 1200 fpm. Bond strengths of film and nonwoven laminates are effectively controlled to make breathable laminates at high speeds. Air cooling devices cause the air to flow substantially parallel to the extruded plastic web during drawdown and provide a plurality of cooling air vortices to effectively cool the web. Film gauge control is also achieved by the method.
