  • Patent number: 8785714
    Abstract: Disclosed herein are nonwoven fibrous structures for use as body fluid acquisition/distribution elements in personal care products. Such structures comprise natural and/or synthetic fibers wherein the fibers have been consolidated by application thereto, and by cross-linking of, a certain type of cross-linkable, vinyl acetate-ethylene (VAE) emulsion copolymer latex binder. The VAE latex binder is one which also comprises an added organic acidulant such as citric acid. Consolidation of the structures with VAE-based binders to which the organic acidulant has been added imparts to the resulting structures the ability to lower the pH of body fluids such as urine passing through the structures. This effect, in turn, provides odor control and skin care benefits to the absorbent articles, e.g., diapers and adult incontinence products, using such structures as acquisition/distribution elements.

  • Patent number: 7931780
    Abstract: A wet paper web transfer belt comprises a base body 30, a paper side layer 20, and a machine side layer 23. The paper side layer 20 is composed of a paper contacting side batt layer 21 made of hydrophilic fibers 41 and a base bode side batt layer 22 without the hydrophilic fibers 41, at least the paper contacting side batt layer 21 being impregnated with a high molecular weight elastic body 50 and at least a part of the hydrophilic fibers 41 being exposed on the surface of the paper contacting side batt layer 21. The water contained in the wet paper web remains within the paper contacting side batt layer 21 made of the hydrophilic fibers 41 with only a small amount of water moving into the base body side batt layer 22, thereby reducing dimensional changes of the belt.
