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/cm. 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/&#x3b1;-olefin interpolymer having: a melt index of from about 1 to about 1000 grams/10 minutes, and a density of from 0.870 to 0.950 grams/centimeter, and from 74 to 20 percent by weight of a second polymer which is an ethylene homopolymer or an ethylene/&#x3b1;-olefin interpolymer having a melt index of from about 1 to about 1000 grams/10 minutes, and preferably a density which is at least 0.01 grams/centimetergreater than the density of the first polymer.

Fibers for polyethylene nonwoven fabric

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/cmand the nonelastomeric polyolefin will have a density of at least about 0.890 g/cm. 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.

Laminates of elastomeric and non-elastomeric polyolefin blend materials

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.

Concrete and process to make same

The subject invention is directed to fibers and polymer blend compositions having improved bonding performance. In particular, the subject invention pertains to a multiconstituent fiber comprising a blend of a polypropylene polymer and a high molecular weight (i.e. low melt index or melt flow) ethylene polymer. The subject invention further pertains to the use of the fiber and polymer blend composition which has improved bonding performance in various end-use applications, especially woven and nonwoven fabrics such as, for example, disposable incontinence garments and diapers. The fibers have good spinnability and provide fabrics having improved bond strength and elongation.

Multilayer thermoplastic stretch wrap film having substantial one-sided cling properties is made without the use of polymers with high levels of n-hexane extractables, dissimilar polymer chemistries, or low molecular weight tackifiers. The reverse or cling layer comprises at least one homogeneously branched ethylene polymer composition having a density of about 0.90 g/cc or less and the obverse or non-cling layer comprises an propylene or ethylene polymer composition having a density greater than 0.90 g/cc. The multilayer film is particularly useful for load palletization end-use applications.

Stretch cling film and fabrication method

The subject invention provides a polymer mixture having high heat resistivity, low hexane extractive and controllably lower or higher modulus. The mixture is comprised of at least one first substantially linear ethylene polymer, Component (A), and at least one second ethylene polymer which is a homogeneously branched polymer, heterogeneously branched linear polymer or a non-short chain branched linear polymer. When fabricated into film, the mixture is characterized by a heat seal initiation temperature which is substantially lower than its Vicat softening point as well as a high ultimate hot tack strength. When fabricated as a molded article, the mixture is characterized by high microwave warp distortion while maintaining a lower modulus. The polymer mixture is particularly well-suited for use in multilayer film structures as a sealant layer for such applications as cook-in packages, hot-fill packages, and barrier shrink films. In molding applications, the mixture is well-suited as freezer-to-microwave food storage containers and lids which maintain good flexibility at low temperature to allow easy openability of such containers.
