Most "G. barbadense" production comes from cultivars that produce particularly long fiber, and most of that is made into clothing. Fine (thin) yarn requires long fiber. In turn, this thin yarn is required for intermediate products like lace and high thread-count cloth. The long-fiber cultivars also tend to have particularly strong fibers, making them useful for various industrial products. Historically, "G. barbadense" has been used for the cords of automobile tires and cloth for aircraft wings. It is also used for sewing machine thread.
