Whether you are restoring a classic truck, re-trimming a fleet of delivery vans, or starting an auto upholstery business, the materials underfoot and around you define the quality of the finished work. This handbook explains how carpet and upholstery are actually made: the polymers, fibers, backing materials, and adhesion systems that determine durability, appearance, and comfort. It gives you the specifications that matter, such as fiber density, face weight, tuft bind, and abrasion ratings, and shows you how to test them in the real world.
