WICKING NONWOVEN MAT FROM WET-LAID PROCESS

摘要

Examples of the present technology may include a method of making a nonwoven fiber mat. The wet nonwoven fiber mat may include a first plurality of first glass fibers and a second plurality of second glass fibers. The first plurality of first glass fibers may have nominal diameters of less than 5 µm, and the second plurality of second glass fibers may have nominal diameters of greater than 6 µm. The method may further include curing the binder composition to produce the nonwoven fiber mat. The nonwoven fiber mat have a wick height of between about 1 cm and about 5 cm according to method ISO8787, and the nonwoven fiber mat may have a total normalized tensile strength greater than 2 (Ibf/in)/(Ib/sq) for a sq (100 ft 2 ).
