METHOD FOR PLEATING KNIT OR WOVEN SILK FABRIC

摘要

PURPOSE:To readily enable pleating in a knit or woven silk fabric excellent in hand and crease resistance by irradiating the knit or woven silk fabric with a low-temperature plasma and then pleating the fabric or irradiating a pleated knit or woven silk fabric with the low-temperature plasma. CONSTITUTION:A knit or woven silk fabric composed of 100% silk yarn, degummed, dyed and finished after knitting or weaving is irradiated with a low-temperature plasma (the plasma gas is preferably oxygen gas under 5X10<-1>Torr partial pressure for about 1-5min irradiation time) to etch the material surface region within the range of several to thousands of Angstrom . The resultant fabric is then pleated (normally at 90-160 deg.C for about 20sec to 6min in the case of dry heat conditions in heat treatment) or a pleated knit or woven silk fabric is irradiated with the low-temperature plasma to readily carry out pleating.
