FINE FIBER BARRIER FABRIC WITH IMPROVED DRAPE AND STRENGTH AND METHOD OF MAKING SAME

摘要

A method of producing a fabric comprising producing a fine denier, using either meltblown or spunbond processes, or a combination of the two, followed by crimping, spotbonding using differential bond roll temperatures, and neck-stretching. Fiber having less than or equal to about 1.5 denier is preferred. Bond roll temperature differential is about 10-50 degree F. The mat produced has the unexpected result of improved strength, conformability and reduced stiffness.
