Abstract

In this study effect of aminated polyacrylamid (PAa), glyoxylation of aminated polyacrylamid (G-PAM), and commercial polyamide-epichlorohydrin (PAE) RESINs on dry and wet strengths of dried paper as well as wet web strength of paper was investigated. Eexperiments showed that application of PAa improved PAPER STRENGTHS, and G-PAM produced by glyoxylation of PAa increased favorable effects of PAa on PAPER STRENGTHS. Wet strength of untreated paper and treated papers with 0.4% (based on dry weight of paper) of PAa, G-PAM and PAE were determined 0.09, 0.3, 0.65 and 0.53 N.m/g, respectively, which indicated higher improvement obtained by G-PAM relative to the PAa and commercial PAE. Also, dry strengths of paper improved more significantly by G-PAM in comparison to the PAa and PAE, while application of 0.4% G PAM increased tensile and burst strengths and tensile energy absorption (TEA) by 21.7%, 29.2% and 69%, respectively. Surprisingly, G-PAM improved tensile strength of wet web of paper by 13.4% which could be attributed to the higher reactivity of residual glyoxal in the ambient temperature.
