What kind of fabric finish is used to impart a resistance to soil and water?

The correct choice involves back coating, which is a technique used in the textile industry to apply a layer of resin, latex, or other coatings onto the back side of a fabric. This treatment enhances the fabric's performance by making it more resistant to soil and water. The added layer not only helps repel moisture but also makes cleaning stains easier, thereby extending the life and appearance of the fabric.

Calendering, while it involves pressing fabric between rollers to create a smooth finish, does not inherently confer soil and water resistance. Glazing, which gives a shiny finish to fabrics, also does not offer the same type of protective qualities against moisture and dirt. Fulling is a process that shrinks and thickens wool fabrics but does not specifically relate to enhancing water or soil resistance. Recognizing these distinctions is essential for understanding how different fabric finishes affect performance and application in interior design.
