Following the various problems of the environmental pollution, new techniques
were examined as the method to decrease of the dyestuff and chemical agent
in the dyeing and finishing processes. In this study, the technique of
shrink proof finishing to the cellulosic fiber was investigated using
high pressure over 100MPa. The shrink of cellulosic fiber was controlled
by high pressure treatment. Furthermore, owing to adding a urea and a
thiourea, the ratio of shrink was reduced to half values. The results
of evaluation concerning to comfortableness property and handling property
of fabric showed that the water vapor permeability of fabric was little
affected by the high pressure treatment and the handling properties based
on pure bending and shearing stresses was affected by the high pressure
treatment.
