    Abstract

    Methods for differentiating or identifying various fibers have been worked out in detail by the Textile Institute, Manchester [1]. Heyn [2,3] has suggested that refractive index and birefringence may prove useful in differentiating synthetic fibers; however, most of the work reported in the literature deals with differentiating one type of fiber from another. for fibers of only one type, presumed to be identical in chemical composition, only average values are given. Because all types of synthetic fibers except glass and Vinyon HH® are more or less birefringent, work was undertaken to investigate the significance, if any, of this property. Further, no data on fibers of Indian manufacture are available in the literature. The present paper reports the results of these studies on seven samples of Terene® (polyester) fibers manufactured by four factories in India.
