Investigation of Methods for Determining the Filling Power of Feathers
Abstract
The laboratories at the Philadelphia Quartermaster Depot have been faced on more than one occasion with a multiplicity of tests designed to measure a single property of textile fibers. Before standardization of any given test method it has been the practice to investigate thoroughly the characteristics of each technique to establish its sensitivity, variability and ease of operation and the general availability of the apparatus in the industry concerned with production of the material to be evaluated. The study reported here is concerned with establishing the optimum method for determining the filling power of feather and down mixtures both as a research tool and as an acceptance quality control measurement. Similar studies have been carried out during the war on water repellency, air permeability, breaking strength, stiffness, and thermal conductivity tests. Results of such investigations will be discussed in future reports in this series.
