Easton's 1897 Bible Dictionary:

Fuller
   The word "full" is from the Anglo-Saxon fullian, meaning "to
   whiten." To full is to press or scour cloth in a mill. This art
   is one of great antiquity. Mention is made of "fuller's soap"
   (Mal. 3:2), and of "the fuller's field" (2 Kings 18:17). At his
   transfiguration our Lord's rainment is said to have been white
   "so as no fuller on earth could white them" (Mark 9:3). En-rogel
   (q.v.), meaning literally "foot-fountain," has been interpreted
   as the "fuller's fountain," because there the fullers trod the
   cloth with their feet.
