It's interesting to think about the importance of mechanical stretch fabrics as a technology because it's so common in today's world. Whether it's a knitted tee or a delicate tie design, stretch fabrics are an essential part of most garments in everyone's wardrobe today.

    Spandex fibers are very elastic and can be mixed with other fibers in different ratios to create the desired stretch percentage. The blended fibers are then spun into yarn for knitting or weaving into fabrics.

    The tensile properties of spandex come from the chemical composition of the fiber. Fiber bundles contain two types of segments—short structural segments and long, soft, invisible segments. When you stretch the fiber, the long sections straighten out, extending the length of the fiber. When the force is removed and the stretch is restored, the long segment retracts to the fiber's natural state defined by the bond of the structure and the short segment.

    Spandex is a key ingredient in most modern stretch fabrics, making garments more resistant to stretch by improving recovery.

    Some natural fibers may have inherent elasticity that facilitates recovery, but it may not make a significant difference compared to the effect of yarn and fabric structure on fabric stretch. However, if you are curious about the elastic qualities of natural fibers, such as wool, there can be some natural recovery because the fibers are curled or wavy. Think about how human curly hair works - when you pull the next curl, it elongates and then springs back into shape; this is consistent with wool fibers but on a smaller scale.
