Card

v. t.
  1. To comb with a card; to cleanse or disentangle by carding; as, to card wool; to card a horse.
  2. To clean or clear, as if by using a card.
  3. To mix or mingle, as with an inferior or weaker article.

In the manufacture of wool, cotton, etc., the process of carding disentangles and collects together all the fibers, of whatever length, and thus differs from combing, in which the longer fibers only are collected, while the short straple is combed away. See Combing.
