Patent number: 8410006Abstract: The present invention is directed to a high surface area fibers and an improved filter composite media made from the same. More specifically, the composite media preferably comprises a winged-fiber layer having high surface area fibers for increased absorption and strength and a meltblown layer for additional filtration. In one preferred embodiment the high surface area fibers have a middle region with a plurality of projections that define a plurality of channels, which increases the surface area of the fiber. In one preferred embodiment, the high surface area fiber has a specific surface area of about 140,000 cm2/g or higher and a denier of about 1.0 to about 2.0. The high surface area fiber of the present invention is made using a bicomponent extrusion process using a thermoplastic polymer and a dissolvable sheath.Type: GrantFiled: June 12, 2007Date of Patent: April 2, 2013Inventors: Walter Chappas, Behnam Pourdeyhimi
