Fibers made a polyethylene composition, and method of making the same. The polyethylene composition comprises less than or equal to 100 percent by weight of the units derived from ethylene and less than 20 percent by weight of units derived from one or more &#x3b1;-olefin comonomers; wherein said polyethylene composition has a density in the range of 0.930 to 0.960 g/cm, a molecular weight distribution (Mw/Mn) in the range of 1.70 to 3.5, a melt index (I) in the range of 1 to 300 g/10 minutes, a molecular weight distribution (Mz/Mw) in the range of less than 2.5, a shear viscosity in the range of 20 to 250 Pascal-s at 3000 sshear rate measured at 190&#xb0; C., vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of said composition; and wherein the fiber is a monocomponent meltspun fiber.

A carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one olefin block copolymer, especially ethylene based block copolymers An olefin block copolymer is extrusion coated onto the back surface of a primary backing to provide an adhesive backing Additional steps and procedures can include washing or scouring the primary backing and fibers prior to the extrusion step, and utilizing implosion agents The preferred olefin block copolymer is an ethylene based block interpolymers The constructions and methods are suited for making tufted, broad-loom carpet having improved abrasion resistance.

Extensible bicomponent fibers and webs particularly adapted for disposable personal care product component applications. Sheath/core configurations providing desirable feel properties for elastic embodiments when compared with conventional elastic fibers and webs are obtained with specific olefin polymer combinations and sheath configurations.

Fibers that exhibit good elasticity or extensibility and tenacity, and low modulus are prepared from propylene-based copolymers. The propylene-based copolymers comprise at least about 50 weight percent (wt %) of units derived from propylene and at least about 8 wt % of units derived from one or more comonomers other than propylene, e.g., ethylene. Particularly preferred propylene copolymers are characterized as havingC NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In one aspect of the invention, fibers are subjected to stress-induced crystallization by subjecting the fiber to tensile elongation during draw.
