Abstract:
1. A non-woven composite comprising: (i) a plurality of strength-imparting fibers, the strength-imparting fibers being present in an amount of between about 20% and about 40% of the weight of the non-woven composite; (ii) a plurality of binder fibers, the binder fibers having a low-melt component and being present in an amount of between about 50% and about 70% of the weight of the non-woven composite; and (iii) a plurality of flame retardant fibers, the flame retardant fibers being present in an amount of between about 5% and about 20% of the weight of the non-woven composite, wherein at least a portion of the strength-imparting fibers have a denier that is at least twice the denier of the binder fibers, wherein the strength-imparting fibers, binder fibers, and flame retardant fibers form a single homogeneous layer, and wherein the low-melt component of the binder fibers forms a skin on both sides of the non-woven composite, wherein the strength-imparting fibers, binder fibers, and flame retardant fibers are comprised of the same thermoplastic material.
