Modern Stretch Bengaline is a blend of rayon, nylon and spandex with an interesting weave. The weft contains stretchy thinner threads and the warp threads are somewhat thicker and stable. The result is a very stretchy woven fabric, up to 40%, but on the lengthwise grain (parallel to the selvedge). There is no stretch on the crossgrain. Therefore most people prefer to use the crossgrain as the straight of grain so that the stretch goes around the body.Stretch Bengaline is often used in ready-to-wear for pull-on pants because it has great stretch and recovery, reducing bulk for a more streamlined look. And it is a little dressier than denim or cargo twill. Stretch Bengaline is comfortable and easy care with fewer wrinkles.
