Serisizing

SERISIZING

A process which is based upon the application of a solution of silk to the surface of a cotton thread, very similar to the application of a sizing mixture, only of a considerably thinner consistency. Silk dissolved in alkalis is readily thrown out of solution by the addition of acid. When such a solution has been applied to a cotton thread, and the thread afterwards passed through a weak acid bath, the sericin of the silk is deposited upon the fibres in an insoluble form which then permits the cotton to be washed and dried.
