Dependence of wool fabric dimensions on temperature and pH
In wool dyeing and finishing processes, fabric is often subjected to a variety of physical and chemical environments. It is shown in this paper that measured dimensions of wool fabrics are dependent on fiber swelling which is influenced by both temperature and pH. In water at pH 2. 1, increasing temperature produced contraction of wool fabrics rather than expansion. The magnitude of the contraction was dependent on fabric structure and any permanent setting treatment to which the fabric had been subjected. At room temperature and the wool isoelectrie point of pH 4.8, wool fiber swelling was found to be at a minimum and increased at lower and higher pHs. Fabric contraction at low pH was observed and can be attributed to greater fiber swelling.
