摘要： 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.

摘要： A paper product and a method of making a paper product with a glabrous surface and adapted for use either dry or for use in a manually pre-moistened condition. The paper product having temporary wet strength exhibiting an initial normalized CD wet tensile strength of at least about 75 g/3 inch strip, preferably 105 g/3 inch strip as measured by the Finch Cup Test 5 seconds after immersion and a subsequent CD wet strength of less than 1/2 as measured 10 minutes after immersion. A temporary wet strength agent comprising uncharged chemical moieties such as aldehydes, and aldehydes containing polymers, polyols and cyclic ureas or mixtures thereof in the range of from about 2 pounds per ton to about 30 pounds per ton is added to the web. Optionally starch and a cationic nitrogenous softener/debonder is added. The starch and softener/debonder are added to assist in tailor making the desired paper product having temporary wet strength. The dry CD tensile strength of the paper product is from at least about 399 g/3 inches up to about 801 g/3 inches, and the tensile modulus is from about 10 to about 32 g/% strain while the GM MMD friction is from about 0.26 to about 0.10. When rubbed against a skin-like surface in a moistened condition, the paper product remains substantially free of pilling.

摘要： Non-aqueous solvents are removed from a web material, e.g., paper, by contacting the material with a condensable, heat transfer vapor, e.g. saturated steam, in countercurrent fashion. The heat transfer vapor is employed in the process in amounts of at least 50% by weight of the solvent to be removed. The process allows effective and efficient total removal and recovery of the solvent without damage to the web material. The condensable heat transfer vapor, as well as being the source of energy for evaporating the solvent, acts as a solvent vapor carrier. Condensation of the mixture in a recovery apparatus, e.g., condenser or still, allows easy recovery of the solvent.
