DIMENSIONALLY STABLE BONDED NONWOVEN FIBROUS WEBS |
摘要 |
A method for making a bonded nonwoven fibrous web comprising extruding melt blown fibers of a polymeric material, collecting the melt blown fibers as an initial nonwoven fibrous web, annealing the initial nonwoven fibrous web with a controlled heating and cooling operation, and collecting the dimensionally stable bonded nonwoven fibrous web is described. The bonded nonwoven fibrous web shrinkage is typically less than 4 percent relative to the initial nonwoven fibrous web. |
