Taffata or Taffety.
A fabric made of silk; at one time it was watered; hence Taylor says, No taffaty more changeable than they. Notre mot taffeta est formé, par onomatopée, du bruit que fait cette étoffe. (Francisque-Michel.)
The fabric has often changed its character. At one time it was silk and linen, at another silk and wool. In the eighteenth century it was lustrous silk, sometimes striped with gold.
