light spots in dyed cotton fabrics can be caused by immature cotton. the spots can occur when clumps of immature fiber have reduced dye affinity. they can be caused when the flattening of the clumps during processing result in the formation of small, highly reflective surfaces. or they can be caused by poor dye penetration that leaves undyed areas if the clumps of loosely attached immature fibers change position after dyeing. the dye affinity of immature cotton can be improved by treating the fiber with a swelling agent such as caustic soda. 8 refs
