The application of starch to fabric imparts stiffness and smoothness. This process involves coating fibers with a thin layer of a polysaccharide derived from plants, most commonly corn, wheat, or rice. Once applied and dried, it forms a semi-rigid film. For instance, a dress shirt treated in this way will maintain a crisp, wrinkle-free appearance even after prolonged wear.
Its importance lies in providing a more polished and professional aesthetic to garments. Historically, it served as a crucial element in maintaining the desired silhouette and formality of clothing, especially in eras when wrinkle-resistant fabrics were unavailable. Beyond aesthetics, it can also offer a degree of protection to fabrics by reducing the absorption of dirt and grime, potentially prolonging the lifespan of frequently worn items.
