  • Patent number: 8673117
    Abstract: 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.

  • Patent number: 8444812
    Abstract: The invention provides a composition of matter used to produce very soft high grades of tissue paper. The composition of matter comprises a PAE resin acidified with a multifunctional acid. The multifunctional acid includes but is not limited to carboxyl and sulfonyl. The acid has a functional group selected from carboxyl and sulfonyl and a functional group selected from carboxyl, sulfonyl, hydroxyl, lactone, phenol, amine and heterocycle. The PAE resin facilitates the use of an adhesive in a Yankee Dryer apparatus that is durable when the adhesive is wet but remains soft when the adhesive becomes dry. These properties allow the adhesive to be strong and remain engaged to the dryer apparatus when wet but be easily removed by the creping blade when dry.

  • Patent number: 8101045
    Abstract: The invention provides a composition of matter useful for producing very soft high grades of tissue paper. The composition of matter comprises an adhesive composition that includes a glycerol-based polyol. The glycerol-based polyol prevents the composition from becoming brittle and is non-volatile. This allows the composition to become rewetted after creping and allows for strong levels of adhesion even at high temperatures.
