The invention provides polypropylene compositions for producing soft nonwoven fabrics, consisting of at least three propylene-based copolymers differing in content of alpha-olefin comonomers. The provided fabrics are soft and pleasant to touch.

Methods and (articles of manufacture therefrom) including forming an elastic film from a polymer composition; tensioning the elastic film to a stretch ratio of between 2 and 6 in the MD; laminating the elastic film to an extensible facing to provide an elastomeric laminate having a CD hysteresis loss of 70% or less and an MD hysteresis loss of 50% or less.

A woven geotextile fabric utilizes a plurality of yarns including machine direction field yarns, cross machine direction field yarns, machine direction rib yarns, and cross machine direction rib yarns. The plurality of yarns is integrally woven together. The machine direction rib yarns and the cross machine direction rib yarns cooperatively define an integrated geotextile grid integrally within the woven geotextile fabric. The machine direction field yarns and the cross machine direction field yarns cooperatively define fabric areas in a field of the integrated geotextile grid generally between the machine direction rib yarns and the cross machine direction rib yarns.

The present invention is directed to a three-dimensional composite fabric including a three-dimensional woven fabric, and a nonwoven fabric arranged on a first, on a second side, or on both sides of the three-dimensional woven fabric, wherein the composite fabric retains at least 15% thickness at a compression of about 200 pounds per square foot (psf) to about 1000 pounds per square foot. Further, the present invention is directed to a method of making a three-dimensional composite fabric and a method of installing the three-dimensional composite fabric in a landfill.

The improved multifilament structure is a low denier, heat treated multifilament structure that provides for advantageous mechanical properties, including fray resistance, low shrinkage, high tensile strength and low elongation.

[Problem] To provide a nonwoven fabric (pasting mat) that does not undergo bonding between the nonwoven fabrics (pasting mats) even under severe conditions (a pressure in winding and a high temperature and a high humidity in transportation, storage, and production).

[Means for Resolution] A pasting mat for lead acid batteries, containing a microglass fiber and a heat-fusible binder fiber, the pasting mat having a thickness under a pressure of 20 kPa of 0.1 mm or more and 0.5 mm or less, and having a bonding strength between the pasting mats after being left for 48 hours under a pressure of 5 to 10 kPa in an environment of a temperature of 70 to 90° C. and a humidity of 75% of less than 0.05 N.

A macro-synthetic fiber includes three or more partially fused filaments made of a polymer composition including at least one polypropylene, wherein the fiber has a multi-lobal cross-sectional shape with three or more lobes. A method produces macro-synthetic fibers, a cementitious material includes a binder and macro-synthetic fibers, and a method for forming a concrete surface uses a concrete mixture modified with the macro-synthetic fibers.

The present invention provides a chargeable sheath/core-structured fiber that contains a polypropylene-based resin as a main resin, wherein the sheath part contains (a) a carboxylic anhydride-modified polyolefin and (b) at least one antioxidant selected from the group consisting of a combined antioxidant a phenolic antioxidant and a phosphorus-based antioxidant, and sulfur-based antioxidants; and (c) an oil containing a polyoxyalkylene alkyl ether represented by the general formula (I) as a finishing oil is deposited on the outer surface of the sheath part, and that can satisfy heat resistance and charge retainability. (In the formula, R.sup.1 represents a saturated or unsaturated aliphatic hydrocarbon group having 10 to 30 carbon atoms; R.sup.2 represents a hydrogen atom or a methyl group; and k is an integer of 1 to 4.)

An example debriding pad includes a support layer, a first region, and a second region. The first region includes a first material defining a plurality of first loop piles arranged on the support material. The second region includes a second material defining a plurality of second loop piles arranged on the support material. The second material is stiffer than the first material to provide more aggressive debridement of a wound.

Provided is a composite sheet material having a first layer and an airlaid nonwoven layer overlying the first layer wherein the airlaid nonwoven layer includes a blend of bamboo derived staple fibers and non-cellulose staple fibers, and in which the airlaid nonwoven layer includes a first surface disposed towards, and thermally bonded, to a surface of the first layer, and a second surface defining an outer surface of the composite sheet material.
