Microscopic Tracking of White-Speck Defects from Bale to Fabric

W.R. Goynes, B.F. Ingber, P.D. Bel-Berger, D.P. Thibodeaux, P. Dastoor


Structures of materials that compose "white speck" defects on cotton fabrics are the same as that of undeveloped cotton fibers that contain only primary wall, or primary wall and very thin layers of secondary wall. Bundles of these unseparated, very immature fibers are found on undeveloped seed, or motes. Such undeveloped seed and fibers are harvested along with normal seed. Microscopic examinations were made of samples from various stages of processing to determine whether the compressed fiber bundles were removed during any process or were carried with the normal fibers through yarn and fabric production. Samples were examined from bale cotton, chute cotton, card sliver, yarns, and fabrics to determine the presence of undeveloped fiber bundles. In lots where defects were found in bale cotton, they were also abundant in all samples.
