Abstract

The heat and mass transfer model developed in Part I has been further modified to evaluate the steaming of blended and interleaved fabric-wrapper assemblies. Various conditions relating to the batch decatizing of a wool fabric with a cotton, nylon, or polyester wrapper have been examined. Results of the computations show that cotton wrappers produce a constant and uniform increase in the regain of wool fabric, but a high fabric temperature may result when steaming a low-regain assembly. With nylon or polyester wrappers, fabric regain increases significantly with steaming time, while fabric temperature remains close to the steaming temperature. The effects of initial temperature, moisture content, and wrapper fiber type on the wool fabric are greater at higher wrapper-to-fabric weight ratios.
