摘要： A degrading agent composition for use in manufacturing a tissue product generally includes a degrading agent, a degradation inhibiting carrier, and a non-ionic surfactant. The non-ionic surfactant stabilizes the viscosity of the composition as a function of time. The degrading agent composition can be used in combination with a temporary wet strength agent to produce a tissue product exhibiting high initial wet tensile strength and desirable decay properties. Processes for forming the tissue product and pumpable fluids containing the degrading agent composition are also disclosed.

摘要： Compositions comprising a blend of two or more paper strengthening agents have improved stability compared with previously known paper strengthening agents. One component is a polymeric paper strengthening agent, preferably a wet strengthening agent. The other component is a stabilized glyoxalated polyacrylamide prepared by (1) reacting a first portion of glyoxal with a polyacrylamide having pendant amide groups to form a first reaction mixture comprising glyoxalated polyacrylamide; (2) adding an acid to the first reaction mixture to form a second reaction mixture having a reduced pH and comprising the glyoxalated polyacrylamide; and (3) adding a second portion of glyoxal to the second reaction mixture to form the stabilized glyoxalated polyacrylamide. If desired, an aldehyde scavenger can be included in one or more of step (1), step (2), step (3), or the stabilized glyoxalated polyacrylamide. Such compositions can be used to enhance the strength of paper, particularly the wet strength of paper.
