Which fabric finish adds weight and stiffness to a material?

The finish that adds weight and stiffness to a material is known as weighting. This process involves applying a substance to the fabric that increases its density, thereby enhancing its drape and giving it a more substantial feel. Weighting is commonly used in textiles to improve the overall handling characteristics of the fabric, making it more suitable for certain applications, such as in garments where a structured appearance is desired.

In contrast, while finishing refers to a broader range of processes that enhance a fabric's appearance or performance, it does not specifically entail the addition of weight and stiffness. Coating involves applying a layer to the surface of the fabric, which may provide water resistance or durability but does not intrinsically enhance weight or stiffness. Texturing, on the other hand, typically alters the surface pattern or feel of the fabric without significantly changing its weight or rigidity. Therefore, weighting is the specific term used for processes that add both weight and stiffness, making it the correct choice in this context.
