Abstract
Changes were evaluated in water absorbency after softening treatment in hydrophilic and hydrophobic fabric specimens. Two household softening agents containing conventional type DSDMAC or improved water absorbency type DODMAC as the primary component were used. The Bilec method showed a marked decrease in water absorbency in cotton toweling cloth treated with DSDMAC but a considerable increase in polyester taffeta, treated with DODMAC. The present method using a heat flowmeter to measure absorption limited to water drops showed slight effects of softening on hydrophilic cotton specimens but improvement in water absorbency and rapid drying in hydrophobic polyester specimens that are structurally slightly water absorbent.
