Table 2 Mean differences in fabric hand and fabric smoothness by three combinations of washer and dryer used

From: Comparisons of fabric care performances between conventional and high-efficiency washers and dryers

  Washer/dryer used F

Mean SD Mean SD Mean SD
Fabric hand 2.82b .36 3.03a .36 3.14a .36 8.32***
Fabric smoothness 2.35b .05 2.70a .05 2.83a .05 14.39***
  1. Fabric hand was evaluated by a rating of 1 to 5. “5” indicates “much softer than the standard unwashed fabric,” “3” indicates “as the standard unwashed fabric,” and “1” indicates “much rougher than the standard unwashed fabric”
  2. Fabric smoothness was evaluated by a rating of 1 to 5. “5” indicates the best performance (i.e., smooth without any wrinkle)
