The oldest process, mercerising or stretching the fibres itt a bath of caustic alkali, produces an inferior gloss. In newer methods, the cotton fibres are practically covered with a coating of artificial silk, either by dipping them into solutions of cellulose similar to those from which artificial cellulose similar to those from which artificial silk is made, or by treating them with solvents of cellulose, and thus forming the silky coating out of the fibres themselves.
