- Sizing agent — A chemical substance or macromolecular colloidal preparation (based on starch, gelatin, synthetic resins, or cellulose derivatives) used in the industrial or household finishing of fabrics; it also defines the protective film resulting from applying this substance, serving to provide textile materials with structural stiffness, luster, smoothness, and resistance to dirt or wrinkling.
- Starch — To subject a textile material, fabric, or shirt collar to the finishing process by applying a layer of sizing agent or starch.
