Sweet Potato Starch as a Sizing Agent in the Textile Industry

Abstract

An intensive study to determine the possibilities of sweet potato starch as a warp sizing agent in the textile industry has been made in the laboratories of the Engineering Experiment Station of the Alabama Polytechnic Institute in cooperation with the Bureau of Standards and the Bureau of Agricultural Chemistry and Engineering of the Department of Agriculture at Auburn. Various tests were developed for the evaluation of starches as a sizing agent and sweet potato starch was evaluated by means of these and other tests. As a ,result of this work it was found that sweet potato starch has the qualities of a good warp sizing agent and in some respects it is superior to a high-grader commercial starch.
