摘要:
An absorbent sheet of cellulosic fibers with upper and lower sides includes (i) a plurality of fiber-enriched hollow domed regions on the upper side of the sheet having a relatively high local basis weight, (ii) connecting regions of relatively lower local basis weight forming a network interconnecting the relatively high local basis weight domed regions of the sheet, and (iii) transition areas with upwardly and inwardly inflected consolidated fibrous regions transitioning from the connecting regions into the domed regions.

A soft and resilient, cold-water dispersible polyurethane foam suitable for disposable personal care products is produced by the combination of corn syrup, glycerin, polyether diamine, PEG, a diisocyanate, water and a catalyst. The formulation and reaction conditions for forming the inventive foam are judiciously selected and carefully controlled to achieve water dispersibility and the desired mechanical properties. The characteristic resiliency, or percent rebound for the foams was generally over 75% and the foams are readily produced as soft foams, exhibiting a relative compression value of from 20% to 150% of that of a commercial polyurethane foam cosmetic pad which is not water dispersible. The foam may be incorporated into webs or stackable products or nestable three-dimensional products.

A high efficiency disposable cellulosic wiper includes (a) pulp-derived papermaking fiber; (b) up to 75% by weight regenerated cellulosic microfiber having a characteristic CSF value of less than 175 ml, the microfiber being selected and present in amounts such that the wiper exhibits a Laplace pore volume fraction at pore sizes less than 15 microns of at least 1.5 times that of a like wiper prepared without regenerated cellulose microfiber. The wipers of the invention exhibit remarkable residue removal efficiency.
摘要:
An absorbent paper sheet includes cellulosic papermaking fiber and up to about 75 percent by weight fibrillated regenerated cellulose microfiber which may be regenerated from a cellulosic dope utilizing a tertiary amine N-oxide solvent or selected ionic liquids. Fibrillation of the microfiber is controlled such that it has a reduced coarseness and a reduced freeness as compared with unfibrillated regenerated cellulose microfiber from which it is made and provides at least one of the following attributes to the absorbent sheet: (a) the absorbent sheet exhibits an elevated SAT value and an elevated wet tensile value as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (b) the absorbent sheet exhibits an elevated wet/dry CD tensile ratio as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (c) the absorbent sheet exhibits a lower GM Break Modulus than a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber; or (d) the absorbent sheet exhibits an elevated bulk as compared with a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber.

摘要:
An absorbent cellulosic sheet is formed by belt creping a nascent web at a consistency of 30% to 60% utilizing a generally planar perforated polymeric creping belt to form a sheet with fiber-enriched higher basis weight hollow domed regions on one side of the sheet joined by a network of lower local basis weight connecting regions forming a network where upwardly and inwardly inflected consolidated fibrous regions exhibiting CD fiber orientation bias form transition areas between the connecting regions and the domed regions. When formed into roll products, the cellulosic sheets exhibit a surprising combination of bulk, roll firmness, absorbency and softness. The consolidated fibrous regions are preferably saddle shaped and exhibit a matted structure on both their outer and inner surfaces.

摘要:
A container for holding pourable contents includes an exterior surface, an interior surface, an interior for holding contents and a reclosable pour spout mounted on the container. The pour spout includes a flange member having oppositely positioned first and second sides. An aperture extends through the flange member and the second side of the flange member is secured to the outer periphery of the wall of the container. An extension is connected to and extends axially away from the outer surface of the container and the extension has an aperture extending therethrough that communicates with the aperture in the flange member. A stem is connected to and extends axially away from the second side of the flange member. The stem has an aperture extending therethrough that communicates with the aperture in the flange member and the pour spout is positioned on the container such that the stem extends through the opening in the wall of the container and into the interior of the container. At least a portion of the stem is turned outwardly and toward the interior surface of the wall to which the flange member is secured to produce a mechanical engagement between the turned stem and the container which tends to resist any tendency of the pour spout to be pulled from the container.
