Change in Pore Structure of Woolen Fabrics under Finishing Process

Abstract

The effects of the conventional finishing treatments on the structure of woolen fabrics were investigated by the measurement of the change in the pore size distribution in the fabrics. The pore size distribution was estimated by a liquid absorption method using n-dodecane combined with a centrifugal liquid removal technique, which could cover a wide range of pore radius from 0.18 to 1722μm. By this procedure the changing behavior of the pore size distribution of sample fabrics on each step of finishing, such as scouring, fulling, raising, fluff shearing and decatizing, was clarified.
