Abstract: The disclosure relates to pre-moistened webs and wipes having visible compressed sites that provide the perception of a cloth-like texture. The disclosure also relates to a nonwoven web made of non-thermoplastic fibers with at least one compressed site on the surface of the web that remains visible when the web is pre-moistened.
Abstract: Hemicellulose fibers, more particularly to non-naturally occurring fibers incorporating hemicellulose, processes for making same and fibrous structures incorporating same are provided.
Abstract: The present invention relates to a starch composition comprising starch, a polymer that is substantially compatible with starch and has a weight-average molecular weight of at least 500,000 such that the polymer forms effective entanglements or associations with neighboring starch molecules, and preferably at least one additive to improve melt flow and melt processability. The additive may be a hydroxyl plasticizer, a hydroxyl-free plasticizer, a diluent, or mixtures thereof. The composition is melt processable on conventional thermoplastic equipment. The composition is especially suitable for uniaxial and biaxial extensional processes to make fibers, films, foams and like products.

Abstract: A method for making a fibrous structure including a plurality of synthetic fibers disposed in a predetermined pattern and a plurality of cellulosic fibers generally randomly distributed throughout at least one layer of the fibrous structure. The method includes depositing an aqueous slurry including synthetic fibers and an aqueous slurry including cellulosic fibers onto a fluid-permeable forming member having a pattern of channels. The slurries are dewatered to form a fibrous web, wherein the at least some of the cellulosic fibers are randomly distributed throughout at least a portion of the fibrous web and a plurality of synthetic fibers are at least partially non-randomly distributed in the channels.
