    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 method of making a belt-creped absorbent cellulosic sheet. A paper making furnish is compactively dewatered to form a dewatered web having an apparently random distribution of papermaking fiber orientation. The dewatered web is applied to a translating transfer surface that is moving at a transfer surface speed. The web is belt-creped from the transfer surface at a consistency of from about 30% to about 60% utilizing a generally planar polymeric creping belt having a plurality of perforations, under pressure, in a belt creping nip defined between the transfer surface and the creping belt. The belt travels at a belt speed that is slower than the speed of the transfer surface. The web is creped from the transfer surface and redistributed on the creping belt to form a web having a plurality of interconnected regions of different local basis weights. The web is then dried.

    摘要: Certain substituted phenolic compounds when used with or without 1,2-epoxides as the sole stabilizer components are very effective in stabilizing n-propyl bromide (NPB). In a standard commercially important 60° C. stability test, representative substituted phenolic compounds used pursuant to this invention, can enable NPB to pass the test even though present at levels of about 50 ppm (wt/wt) or less in NPB containing no other stabilizer additive component. In fact, amounts as low as 1 ppm have been found effective with various substituted phenolic compounds. In addition, it has been found that one of the preferred stabilizers of this invention—2,6-di-tert-butyl-p-cresol—even though higher boiling than NPB, left inconsequential amounts of residue at least throughout the range of 1 to 30 ppm (wt/wt). Also, it has been found that certain other preferred stabilizers of this invention can provide synergistically improved stability in passing the 60° C. stability test when used with at least one 1,2-epoxide, notably butylene oxide.

    摘要: A multi-ply absorbent sheet includes at least a first and second ply bonded together. In one construction, the first and second ply are provided with from about 90% by weight to about 25% by weight pulp-derived papermaking fiber and from about 10% to about 75% by weight fibrillated regenerated cellulosic microfiber having a characteristic CSF value of less than 175 ml; the sheet having a caliper of from 180-250 mils/8 sheets and exhibiting a wipe-dry time of less than 20 seconds, an SAT capacity in the range of 350-500 g/m2, an SAT rate in the range of 0.05-0.25 g/s0.5, a CD wet tensile in the range of 400-2500 g/3″ and a wet/dry CD tensile ratio of from 35% to 60%. The multi-ply sheets are efficient, high capacity wipers and have enough absorbent capacity to be used as ordinary paper towels. Preferred wiper towel products exhibit a differential pore volume for pores under 5 microns in diameter of at least about 75 mm3/g/micron.
