摘要： The present invention relates to processes for softening cellulose pulp using chemical softening agents or debonders, which include compositions comprising lower alkyl acid esters or cyclic esters of polyhydroxy compounds, without adversely affecting the absorbency of the cellulose fiber products thereof, and products thereof. The process of the invention may also be used in combination with plasticizing agents for cellulose such as glycerol, mono- and di-saccharides, glycols, and oligomers thereof. The process of the invention provides cellulosic fiber which is easier to fluff (refiberize) and to subsequently densify airlaid pads formed from the resulting individualized fibers, without adversely affecting absorbency.

摘要： Processes for rendering a polyamine-epihalohydrin resin storage stable, including processes that prepare a storage stable resin and/or processes that treat resins. A composition containing a polyamine-epihalohydrin resin with a solids content of at least 15 wt % treated with at least one enzymatic agent under conditions to at least one of inhibit, reduce and remove the CPD-forming species to obtain a gelation storage stable reduced CPD-forming resin so that the composition containing the reduced CPD-forming polyamine-epihalohydrin resin when stored for 24 hours at 50null C., and a pH of about 1.0 releases less than about 250 ppm dry basis of CPD for wet strength polyamine-epihalohydrin resin and less than about 100 ppm dry basis of CPD for creping polyamine-epihalohydrin resin. A process for treating polyamine-epihalohydrin resin, to reduce the level of the nitrogen-free organohalogen compound by adding at least one microorganism, or at least one enzyme isolated from the at least one microorganism to an aqueous composition containing a solids content of at least 15 wt %, under conditions to dehalogenate the nitrogen-free organohalogen compound so as to reduce a level of the nitrogen-free organohalogen compound while leaving the polyamine-epihalohydrin resin substantially intact. A process for rendering a polyamine-epihalohydrin resin storage stable by treating the resin of less than 15 wt % with at least one enzymatic agent under conditions to at least one of inhibit, reduce and remove the CPD-forming species to obtain a gelation storage stable reduced CPD-forming resin that when stored for 24 hours at 50null C., and a pH of about 1.0 releases less than about 250 ppm dry basis while simultaneously treating the polyamine-epihalohydrin resin by contacting with at least one microorganism, or at least one enzyme isolated from the at least one microorganism, in an amount, and at a pH and temperature effective to dehalogenate residual quantities of organically bound halogen. A paper product containing the storage stable polyamine-epihalohydrin resin, when corrected for adding at about a 1 wt % addition level of the resin, contains less than about 250 ppb of CPD.

摘要： Absorbent wetlaid paper containing at least 1% by weight, calculated on the dry weight of the paper, of an absorbent polymeric material having a thermo-reversible liquid uptake capacity, which has a cloud point, Cp, in water within the temperature interval 30-60 null C., preferably 35-55null C., at which the polymer has a substantially higher liquid uptake capacity at temperatures below said cloud point as compared to at temperatures above the cloud point. The thermo-reversible polymer will then be inactive during the papermaking process and be activated to its swelling and absorbent form when it is brought into contact with a liquid, the temperature of which is below the cloud point, Cp, of the polymer.
