AbstractEight types of structural deformities have been identified in cotton fibers by using the SEM, and their incidence has been quantified in four varieties grown in India. Although the total number of deformities per cm was found to be nearly equal in these four varieties, their number showed a wide spread when structural reversals (which constitute one class of deformity) were excluded. The correspondence found between the number of defects other than reversals and the drop in bundle tenacity with increase in gauge length seems to suggest that weak links other than reversals might strongly influence fiber strength.
