Abstract
Artificial silk spun on unyielding perforated bobbins is washed and after-treated, e.g. desulphurized, by the pressure or suction method using the perforations, and then, prior to drying, the perforations are rendered ineffective so as to prevent moisture from escaping through them. By this means irregularities caused by uneven contractions are avoided. The perforations may be rendered ineffective by closing the bobbins at the ends, or a number of bobbins may be superposed to form a column and the column closed, or the bobbins may be slid on a tube, or the inner surface of the bobbin may be covered by fitting an elastic sleeve. If desired, the drying of the artificial silk may be interrupted prematurely, e.g., when the water content is about 15, 20, or 25 per cent.
