Disposable article that include fibers formed from compositions comprising thermoplastic polymers and waxes are disclosed, where the wax is dispersed throughout the thermoplastic polymer.

A sheet of material suitable for roofing or industrial wrapping applications has an anti-skid surface formed by ridges of twisted tapes. The sheet comprises a woven scrim of warp tapes and weft tapes. Some of the tapes are twisted about their longitudinal axis, for example about 25 to 400 revolutions per meter, to form ridges having a height substantially greater than the thickness of the tapes. The ridges impart an anti-skid surface to the sheet. The scrim is bonded to a coating or film to make the sheet waterproof.

A sheet of material suitable for roofing or industrial wrapping applications has an anti-skid surface formed by ridges of twisted tapes. The sheet comprises a woven scrim of warp tapes and weft tapes. Some of the tapes are twisted about their longitudinal axis, for example about (25) to (400) revolutions per meter, to form ridges having a height substantially greater than the thickness of the tapes. The ridges impart an anti-skid surface to the sheet. The scrim is bonded to a coating or film to make the sheet waterproof.

In a woven fabric all warp and weft yarns are elastic, all weft and warp yarns have a stretchable core comprising a first elastic fiber and a second fiber that is less elastic than said first fiber, and the elasticity of the fabric in warp direction is at least 25% and elasticity of the fabric in weft direction (E.sub.weft) is at least 30%, preferably at least 40%.

Provided are: a rubber-reinforcing fiber, in which adhesion between a rubber and a fiber is enhanced and which is thereby capable of further improving the durability than before when used as a reinforcing material; a rubber-fiber composite; and a pneumatic tire using the same. The rubber-reinforcing fiber includes a core-sheath type composite fiber whose core portion is composed of a high-melting-point resin (A) having a melting point of 150 C. or higher and sheath portion is composed of a resin material (B) having a melting point lower than that of the high-melting point resin (A). The resin material (B) includes an olefin-based copolymer composition (X) which contains two or more olefin-based polymers selected from a propylene--olefin copolymer (C1), a propylene-nonconjugated diene copolymer (C2), an ionomer (C3) whose degree of neutralization with a metal salt of an olefin-based copolymer containing a monomer of an unsaturated carboxylic acid or anhydride thereof is 20% or higher, and an olefin-based homopolymer or olefin-based copolymer (D) (excluding (C1) and (C2)).

Fabrics are provided that include mono-component staple fibers, a first group of split staple fibers comprising a first polymeric material, and a second group of split staple fibers comprising a second polymeric material that is different than the first polymeric material. The mono-component staple fibers, the first group of split staple fibers, and the second group of split staple fibers are physically entangled together to define a consolidated nonwoven. The fabrics may be physically entangled by hydroentanglement.

In one aspect, the present disclosure provides a method. The method may include placing an upper on a last, where the upper includes a lower perimeter edge secured to a lasting element, and where the last includes an opening for receiving the lasting element.
