ABSTRACT:
A method of ascertaining relaxation and shrinkage behavior of textile fabrics and textile products where a sample is separately submitted to a short complete washing cycle in a whirling hot washing bath and to a few short complete treatment cycles in a whirling hot water bath, each cycle being finished by a short hydroextraction of the sample and drying in a hot air stream, the method being performed during incessant movement of the yarns at cross-over points and flexing of the yarns in the textile structure of the sample. An apparatus for performing the method of the invention which comprises a vertical perforated drum (1) containing at least (2) radially arranged partitions dividing the drum into two or more chambers and rotatable in two directions, arranged in a heat insulated protecting casing (7), covered by a lid (8), a means which can give the drum alternately a rotational motion or an oscillating motion, an air heater (11) connected over inlets (12) to the inside of the casing (7), above each chamber, and a water heater (15) connected to the casing via a water inlet and outlet pipe (18).
