| Abstract | ||
| Wet strength is one of the most important properties of tissue papers and presently the polyamideamine-epichlorohydrin (PAE) resin is widely applied to develop and conserve wet strength in paper products. In this study, the combined effect of PAE, retention aid (RTN) and carboxymethyl cellulose (CMC) on softness and wet and dry strength properties of tissue paper were investigated. The results showed that combined application of CMC, RTN and PAE significantly improved wet strength and softness of papers, as compared to single application of PAE. Application of 0.2 % RTN with 1% PAE or 0.4% CMC with 1% PAE enhanced wet tensile strength by 10% and 68%, respectively. The combined application of 0.4% CMC, 0.2 % RTA and 1% PAE improved wet tensile strength by 124%, compared to sheets treated with only the 1%PAE. The positive effect of combined application of CMC, RTA and PAE depends on the application ratio of the chemicals. | ||
