Method of forming a fine fiber barrier fabric with improved drape and strength

摘要

A method of producing a fabric comprising producing fine denier fibers, 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. The bond temperature differential is about 10 DEG -50 DEG F. The mat produced has the unexpected result of improved strength, conformability and reduced stiffness.
