Abstract

In order to improve runnability of the production process of combustible cartridge case (CCC), the effects of pre-mixed complexes of polyamideamine-epichlorohydrin (PAE) and polyvinyl alcohol (PVA) on wet-web strength and dry strength of nitrocellulose fibers (NC) - softwood bleached kraft pulp (SwBKP) sheets were investigated in terms of types of PVA. It was found that the addition of PAE or PAE-PVA complexes increased wet web tensile strength and dry strength of NC-SwBKP sheets. In order to improve the wet web tensile strength, the PVA with a higher degree of saponification and with a higher molecular weight had to be chosen for the PAE-PVA pre-mixed complexes. For the dry strength of NC-SwBKP sheets, the PVA with a higher degree of saponification resulted in a higher strength. Concerning the strength improvement of NC-SwBKP sheets, the degree of saponification of PVA was more important factor than the molecular weight of PVA. It is speculated that PAE-PVA pre-mixed complexes improved wet web tensile strength and dry strength of NC-SwBKP sheets by increasing interactions between fibers and by improving formation of sheets.
