The authors discuss the results of their study on the identification, quantification and reduction of white speck defects on dyed cotton fabrics. Using scanning electron microscopy (SEM), the white speck defects were found clinging to a fabric surface and have structures that look similar to that of fibers from mote seed. The defects increased in dyed fiber from chute feed and bale but were reduced by single carding. The tandem carding process showed extended mass when a yarn that contained the white speck was separated from the fabric. The study also found that vat dyes do not demonstrate cellulase activity on cotton while hydrolysis of the substrate occurs during subsequent color removal. |
