Damask, a fabric originally manufactured at Damascus, whence its name. It was made of silk, and was distinguished by its ornamental woven figures of fruits, flowers, animals, and landscapes. It is still distinguished by these ornaments, and by the mode in which they are introduced in the process of weaving, though the material of modern damask is often linen, sometimes indeed woollen, or even cotton, or a mixture of linen and cotton. The cotton fabric, from its want of durability and beauty, has little to recommend it for this manufacture, particularly as it is only by great care and frequent bleaching that it can be made to retain its whiteness. Its peculiar texture is that called tweeling or twilling, in which the warp and the woof cross each other, not alternately, but at intervals of several threads. These intervals being at every eight threads in damask, the stuff is called an eight-leaf twill. The linen damasks manufactured at Dunfermline in Scotland, and at Lisburn and Ardoyne in Ireland, are used chiefly for table cloths and napkins.

Diaper is a variety of damask, differing from it by the warp and the woof crossing each other at intervals of five threads.
