Filament reinforced tapes useful as underwater pipe wrap

A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant yarns on one surface of the backing, and pressure-sensitive adhesive layer that coats the corrosion-resistant yarns and binds them to the backing.

Beamed elastomeric laminate structure, fit, and texture

The present disclosure relates to stranded elastomeric laminates (including bi-laminates and tri-laminates) comprising beamed elastics and may have inventive Dtex-to-Nonwoven-Basis-Weight-Ratios, Dtex-to-Spacing-Ratios, and/or Void-Area-to-Strand-Area-Ratios. The stranded laminates of the present disclosure may be used for disposable absorbent article components (including pant belts) and may comprise inventive bonding arrangements that yield inventive textures and texture arrangements. When the inventive stranded elastomeric laminates are used for pant belts, the pants may have inventive Application-Forces, Sustained-Fit-Load-Forces, and Sustained-Fit-Unload-Forces. Further, when absorbent articles are packaged under compression at inventive In-Bag-Stack-Heights, the stranded elastomeric laminates of the present disclosure maintain their inventive properties and characteristics, including their inventive textures.

Fibrous structures exhibiting improved whiteness index values

Fibrous structures, for example sanitary tissue products, containing a plurality of filaments that employ one or more filament-forming materials, such as one or more hydroxyl polymers, and one or more hueing agents, present within the filaments such that the fibrous structures exhibit a Whiteness Index of greater than 72 as measured according to the Whiteness Index Test Method described herein.

Spunbonded nonwoven with crimped fine fibers

The invention relates to a spunbonded nonwoven having crimped multicomponent fibers, wherein a first component of the multicomponent fibers consists of a first thermoplastic polymer material comprising a first thermoplastic base polymer and a second component of the multicomponent fibers consists of a second thermoplastic polymer material comprising a second thermoplastic base polymer that is different from the first base polymer. The at least one of the first polymer material or the second polymer material is a polymer blend that comprises, further to the respective base polymer, between 1 and 10 weight percent of a high melt flow rate polymer that has a melt flow rate of between 600 and 3,000 g/10 min. The fibers have a linear mass density of less than 1.5 denier. The average crimp number of the crimped multicomponent fibers is in the range of at least 5 and preferably at least 8 crimps per cm in the fiber. The invention further relates to a method for making such spunbonded nonwoven, a multilayer fabric wherein at least one layer comprises such spunbonded nonwoven and a hygiene product comprising such spunbonded nonwoven or multilayer fabric.
