STUDIES ON HAIRINESS OF FABRICS AND YARNS BY LASER RADIATION SCATTERING METHOD

Abstract

Method and apparatus for a measuring of length and density of nap of fabric are presented. Method based on recording of laser radiation flux scattered by fibres that form nap. Experimental conditions provide unitary scattering of radiation by fibres and recorded light flux is proportional total length of fibres. It was found that total length of fibres in three samples of a heavy woolen cloth decreased exponentially as coordinate point recedes from cloth surface. The accuracy in the determination of the fibers total length in the nap is discussed. Modification of the method and the apparatus for a new goal is attained – the hairiness of yarns measuring is described.
