The wool fibers have a natural crimp and they hold onto other fibers strongly which makes the fabric aslo very strong. Third, when the steel wool stopped burning, I noticed that it had changed colors. A pad of steel wool was torn up into many small pieces and then crumbled so very short filaments would fall into a test tube. The mixture was mixed for 10 min, 12 min, 15 min or 20 min respectively, and then samples were prepared with a gyratory compactor. AATCC 99 Dimensional Changes of Woven or Knitted Wool Textiles - Relaxation, Strengthening and Felting; . The metal strips are massed together in a sheet, folded, and turned into pads that are easily held in the hand. The main results show that short and thick fibers disperse very well in the mixture, while long and thin fibers produce clusters. Wool fibers can bend back on themselves more than 20,000 times without breaking - this makes it resistant to wear and tear.
