Calico (in British usage since 1505[1]) is a plain-woven textile made from unbleached and often not fully processed cotton. It may contain unseparated husk parts, for example. The fabric is far less fine than muslin, but less coarse and thick than canvas or denim, but it is still very cheap owing to its unfinished and undyed appearance.
A chlorofluorocarbon (CFC) is an organic compound that contains only carbon, chlorine, and fluorine, produced as a volatile derivative of methane, ethane, and propane.They are also commonly known by the DuPont brand name Freon.The most common representative is dichlorodifluoromethane (R-12 or Freon-12).s in simpler alkanes, carbon in the CFCs and the HCFCs is tetrahedral. Because the fluorine and chlorine atoms differ greatly in size and effective charge from hydrogen and from each other, the methane-derived CFCs deviate from perfect tetrahedral symmetry.
