\Mer"cer*ize\, v. t. [imp. & p. p. {-ized}; p. pr. &
vb. n. {-izing}.] [From (John) Mercer (1791-1866), an English
calico printer who introduced the process + -ize.]
To treat (cotton fiber or fabrics) with a solution of caustic
alkali. Such treatment causes the fiber to shrink in length
and become stronger and more receptive of dyes. If the yarn
or cloth is kept under tension during the process, it assumes
a silky luster. -- {Mer`cer*i*za"tion}, n.
