Abstract
Hole formation in cotton fabrics similar to that observed during the peroxide bleaching process and known as "catalytic damage" may be produced by exposing the fabric to an electrochemical process involving generation of oxygen at platinum anodes. A morphological study of an electrochemically damaged poplin fabric is de scribed. Several morphological fiber changes are identified, including crack formation consistent with granular and spiral splittings. A qualitative model is proposed high lighting a possible sequence of morphological changes that occur during oxidation and culminate in fiber rupture.
