20170232278 · 2017-08-17 ·

A method of making a filtering face piece respirator, which method includes: providing a cup shaped mold 20; providing a forming chamber 24 where the mold 20 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 20 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.

NON-WOVEN FABRIC AND FILTER USING SAME

A non-woven fabric body (11) that forms a non-woven fabric (1) is formed by integrating composite polyester fibers (2) and flame-retardant acrylic fibers (3) which serve as the other fibers of the rest. The composite polyester fibers (2) have a core-sheath structure in which a sheath portion (4) is formed of a low melting point polyester and a core portion (5) is formed of a high melting point polyester having a higher melting point than that of the low melting point polyester. The composite polyester fibers (2) are contained in an amount of 15% to 80% by weight in a total of 100% by weight of the non-woven fabric body (11). Further, an apparent density of the non-woven fabric body (11) ((a basis weight of the non-woven fabric body)/(a thickness of the non-woven fabric body)) is 0.005 g/cm.sup.3 to 0.040 g/cm.sup.3.
