IICRC Upholstery and Fabric Cleaning Technician (UFT) Practice Exam

Luster in fabrics refers specifically to the shine or reflectiveness of the material's surface. It describes how light interacts with the fabric, affecting its visual appeal and texture. Higher luster indicates a more reflective surface that can give the fabric a vibrant and polished look, while lower luster tends to create a more matte appearance. Understanding luster is essential for assessing the quality and appropriate use of fabrics, especially in upholstery and fashion, where aesthetics can significantly influence consumer choices.

The other terms, such as durability, color intensity, and thickness, relate to different characteristics of fabric. Durability pertains to how well the fabric can withstand wear and tear, color intensity deals with the richness or depth of the color, and thickness describes the physical dimension of the fabric. However, these attributes do not define the reflective quality associated with luster.
