Starch, gelatin, glue, and wax added to fabrics in the finishing state to improve touch or weight and to help fabric lying in the cutting phase. Sizing is also applied to reinforce warp yarns during weaving. Most common starches used are corns in the United States, rice in Asia, and potato in Europe, or PVOH and other chemical substances. Look out for fabrics containing P.C.P., a highly toxic chemical still used sometimes as sizing agent.
