Abstract: This study compared the tensile strength of chemically bonded nonwoven fabrics as a function of ionic charges of fibers and fiber finishes and of binders and binder emulsifiers. The binders were applied at normal (20%) and low (5%) concentrations; the low binder level was used to avoid possible masking of ionic interactions. In all, 70 different nonwoven fabrics were prepared for tensile measurements. The means and standard deviations of the tensile data were examined by analysis of variance. The tensiles varied significantly (.05) among the nonwoven fabrics. Multiple comparisons using Scheffé’s tests showed which binders differed significantly (.05) from each other. On the basis of rank ordering the results of Scheffé’s tests, it appeared that greater tensile strength resulted from ionic interaction between the binders and fiber finishes as well as between the binder emulsifie.rs and fiber finishes. There was no indication of ionic interaction between the binder and fiber or binder emulsifier and fiber.
