RESPIRATOR MADE FROM IN-SITU AIR-LAID WEB(S)

摘要

A method of making a filtering face piece respirator, which method includes: providing a cup shaped mold 30; providing a forming chamber 24 where the mold 30 is located and where loose fibers 22 are introduced into air in the forming chamber 24; causing the loose fibers 22 to be accumulated 10 on the mold 30 in the forming chamber 24; and bonding 12 the accumulated fibers to each other at points of fiber intersection. The inventive method thus is beneficial in that it eliminates steps in the manufacturing process. The fibers also are uniformly distributed throughout the mask body, and because the webs do not have to be cut during respirator manufacture, less web waste is generated.
