AbstractSpectacular changes in structure and properties of cotton have been found to result from swelling and stretching treatments in water. Fibers from one variety of cotton (Sudan) were swollen in water and stretched to their limit. While one lot was dried in the stretched state, another was allowed to dry in the slack condition after being subjected to stretch. The two types of treatments produced considerable changes in structural and physical properties, the stretch drying being more drastic. Enhancement of breaking load and tenacity without much loss in extensibility improved fibrillar orientation without change in crystallinity; reduction in ribbon width wall thickness and number of convolutions, etc. are some of the changes resulting from the treatment
