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： 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.
