Subject: Mechanical stretch is: Date: 11/29/10 11:58 AM
It's made on a stretching machine at the factory done by the manufacture. There's no Lycra or Spandex in it to make it stretch, but the machine gives it a stretch even though it's 100% poly. Mechanical stretch is a simple process by which the fabric is woven to a wider width and in the finishing, the fabric is shrunk creating a stretch when pulled. These are fabrics that utilize their memory and bounce back to their original state.
