Abstract: The present invention is generally directed to single ply scrim-like wiping products having great softness and strength. The wiping products are made from a paper web containing softwood fibers in combination with bicomponent fibers. Once formed, the paper web is treated on each side with a bonding agent in a preselected pattern. Both sides of the paper web are also creped. In order to create a wiping product with a scrim-like appearance, a reticular pattern is then embossed into the paper web. Specifically, the pattern is permanently imprinted into the product by compressing and fusing together the bicomponent fibers contained within the lines of the pattern.

Abstract: A soft, absorbent nonwoven fibrous web, such as a wet wipe, capable of dispersing in an aqueous environment into unrecognizable pieces, made by a method comprising the steps of forming a wet-laid nonwoven web from an aqueous slurry of fibers; hydraulically needling the wet-laid nonwoven web; partially drying the hydraulically needled web; applying a binder composition to one side of the web; creping the web such that interfiber adhesion is disrupted and z-direction fiber orientation is introduced; optionally applying a binder composition to the second side of the web; recreping the web; drying and curing the web; and, converting the dried and cured web into a wet wipe, dry wipe, or other absorbent article. In the case of a wet wipe, a solution containing about 100 ppm of calcium ion is applied to the web, such as in a preserving solution. In the case of a dry wipe, the calcium ion is added after the binder is added to the web, and the final product is stored in a dry state.

Abstract: The improved creped non-laminar singular web structure comprising long fibers and short fibers demonstrated by high TWA and Z peeling. Creping causes a certain portion of long synthetic fibers and short fibers to substantially be oriented in a predetermined vertical or Z direction across the thickness of the web structure. In particular, when a stratified preparation containing wet stiff CTMP fibers is used, the vertically oriented CTMP fibers increase the total water absorption (TWA) of the web structure without collapsing. The high TWA print/double-creped paper products manufactured from the above web structure are suitable for heavy wipe and dry uses.

Abstract: An improved method, and resulting product, for creping a web of papermaking fibers by adhering the web to a creping dryer and with a creping blade removing the web from the creping dryer which provides increased absorbency with less reduction in strength. The improvement comprises reducing the cohesive forces between the fibers to a greater extent than reducing the adhesive forces between the web and the creping dryer accomplished by applying a fluid at least primarily comprising water overall to the side of the web away from the creping dryer in sufficient quantity and at a position to accomplish the improved results. The method is particularly useful in the practice of wet creping wherein the web is creped from the creping dryer at a dryness of from 45% to 60%.

Abstract: Moisture-resistant, polyurethane-based, pressure-sensitive adhesives.

Abstract: In U.S. Pat. Nos. 3,437,622 and 3,761,307 and U.S. Pat. application Ser. No. 323,944, filed January 15, 1973 and now abandoned, are disclosed pressure-sensitive adhesives, the required cohesive strength of which is provided by a polyurethane polymer in place of the natural or synthetic rubber of the prior art. However, some of such polyurethane-based adhesives are not highly resistant to moisture unless special procedures are used. For example, they may lose 20 to 75% of their adhesiveness after exposure for 3 days or less to 90% relative humidity at 150.degree.F. This invention discloses means of overcoming this problem by combinations of excluding moisture, adding minor proportions of the reaction-products of hydroxylated elastomers or of hexamethylene tetramine.
