gram resulting in a basis weight of approximately 60 g m 2 the sheets were conditioned under standard recommendations for temperature and humidity tappi method t 402 and evaluated for tensile strength following tappi method t 220 tensile results are tabulated in table ii and again show that the industry standard products arosurf u00ae pa 777v and 842v provided good debonding of the sheets oppositely the nonionic surfactant rewopol e0 70 and the cationic coagulant 8108 plus when dosed by themselves provided minimal or no debonding of the sheets however when the individual nonionic surfactant and cationic coagulant components were combined together as in softener formulations 1 2 and 3 then significant tensile index reductions occurred thus demonstrating the utility of present invention in this example softener formulation 4 was compared to industry standard products arosurf u00ae pa 777 and rewoquat u00ae we 15 dpg available from evonik industries in handsheet debonding experiments handsheets were produced using a messmer model m 153 former according to tappi method t205 the furnish was a 50 50 blend of hardwood and softwood dry lap pulp the softener formulations were added to the furnish at doses of 1 3 and 5 kg mt of dry fiber the diameter of the sheets was 15 9 cm and the corresponding sheet weights were approximately.
