SUNLIGHT DEGRADATION OF VARIOUS TYPES OF RAYON STAPLE

(II) SUNLIGHT DEGRADATION OF RAYON STAPLE FABRICS

Abstract

Standard muslin (No.9 standard structure) was woven with each of high tenacity rayon staple, regular rayon staple and cotton. All fabrics were exposed to the sunlight for five month under the same conditions and results are compared.
Studies of the change in the dry and wet tenacity, dry and wet elongation, tear strength and flexing abrasion for the irradiated samples, when considerations are given primarily to their absolute values and secondary to the relative ones, showed a considerable superiority from practical standpoint of high tenacity rayon staple over cotton and regular rayon staple.
