Abstract: The present invention relates to nonwoven webs or fabrics. In particular, the present invention relates to nonwoven webs having superior abrasion resistance and excellent softness characteristics. The nonwoven materials comprise monocomponent fibers having a surface comprising a polyethylene, said nonwoven material having a fuzz/abrasion of less than 0.7 mg/cm3. The present invention is also related to fibers having a diameter in a range of from 0.1 to 50 denier, said fibers comprising a polymer blend, wherein the polymer blend comprises: from 40 weight percent to 80 weight percent (by weight of the polymer blend) of a first polymer which is a homogeneous ethylene/?-olefin interpolymer having: a melt index of from about 1 to about 1000 grams/10 minutes, and a density of from 0.870 to 0.

Abstract: A nonwoven web made from a polymeric fiber blend comprising at least one elastomeric polyolefin and at least one nonelastomeric polyolefin useful as the elastic base sheet for a nonwoven laminate is disclosed. Preferably, the polymeric blend will comprise a nonelastomeric resin in the range of from about 10 to about 90 percent by weight, and an elastomeric resin of from about 90 to about 10 percent by weight. The elastomeric polyolefin will have a density of less than about 0.885 g/cm3 and the nonelastomeric polyolefin will have a density of at least about 0.890 g/cm3. In one particular embodiment, the polymeric blend may comprise about 50 percent to about 90 percent by weight of a narrow molecular weight distribution polyethylene and about 50 percent to about 10 percent by weight of a nonelastomeric polyolefin such as a linear low density polyethylene.

Abstract: A concrete article comprised of concrete having therein a reinforcing fiber, where at least about 50 percent of the reinforcing fibers are frayed only at an end or ends of the reinforcing fibers, may be made by mixing concrete, water and a reinforcing fiber for a sufficient time to fray the ends of at least 50 percent of the fibers and curing the mixture to form the concrete article. The fiber may be a reinforcing fiber comprised of at least two filaments bonded together and the filaments being comprised of a polymeric core and a polymeric sheath comprised of a fusing-fraying polymer, such that the reinforcing fiber, when mixed with inorganic particulates, frays predominately only at an end or ends of the fiber.
