Tensile Behaviour of Wool Fabric as a Function of Fabric PH
Wool fabric extensibility under a 5 N/cm load was observed to be greatest at the wool isoelectric point of pH 4.8 and lower at both pH 2.1 and pH 7.2.The impact of pH on fabric extensibility is similar to the variation in fabric hygral expansion previously observed.Fabric stress-strain curves at different pHs show that for a given fabric extension level,the work required to stretch a fabric was less at pH 2.1 than at pH 4.8.These results confirm the fact that the strength of wool fabric is at a maximum when the pH of the fibres is close to the isoelectric point.
