Fabric pretreatment and finishing processes lead to or emphasize dyeing defects. Such woolen fabric dyeing defects as uneven fabric center and selvage colors arise from such treatment processes as desizing, carbonizing, kier decating, open width washing, drying, raising, shearing, and calendering. Uneven heat distribution in a dryer provokes differential yellowing between the fabric center and selvage. Uneven raising results from over tensioned or relaxed fabric selvages. Irregular machine geometry leads to uneven shearing. Such treatments as open width desizing, open width washing, mercerizing, and bleaching can cause irregular dye absorption in cellulosic fabrics. Dyeing emphasizes texturing defects in polyester fabrics. Oligomeric elements in polyester fibers precipitate as sports of intense color during fabric dyeing.
