Abstract

The effects of the added amount of sodium dodecyl sulfate, a surfactant, on the drainage rate on wire and the properties of foam-formed hardwood bleached kraft pulp sheet were evaluated to obtain the fundamental data for the development of foam-forming or foam-molding technology. It was discovered that when compared to the traditional papermaking method of water-based sheet manufacturing, the foam-forming technology can improve sheet bulk and formation while significantly reducing sheet strength. The highest bulk was obtained with a surfactant dose of 1 g/L. Formation improved with increasing dosage of surfactant. A surfactant dose of 1 g/L was sufficient to mostly lose the strength of the foam-formed sheet. Under conditions of high vacuum pressure above a certain value, foam-forming improved the drainage property of the wire section compared to the water-based forming, and the drainage was improved by increasing the added amount of surfactant. However, at low vacuum pressure, the drainage of foam-forming was poorer compared to the water-based forming, and the drainage was impaired by increasing the added amount of surfactant.
