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.

摘要： There is provided a thermally stabilized polypropylene melt-blown microfiber acoustical insulation web which has a resistance to thermal degradation at a temperature of 135.degree. C. for at least 10 days. The polypropylene has a thermal stabilizer uniformly distributed within the melt-blown microfiber polymer which polymer when produced is subject to thermal and/or catalytic degradation in the absence of significant levels of thermal stabilizer or antioxidant.
