Cotton T400 hygroscopic, quick drying and easy-care elastic intertexture and afterfinish process

The invention provides a cotton T400 moisture-absorbing quick-drying non-ironing elastic mixed fabric and a finishing process thereof, which relates to introduction of a novel raw material T400 of cotton fabrics and a finishing process thereof. The finishing process comprises the following steps of desizing and then adopting concentrated caustic soda for mercerization, wherein the temperature of setting liquid is 100 DEG C; components in the setting liquid are 70g/l of resin, 35g/l of strength protecting agent, 50g/l of easy-decontamination finishing agent and 21g/l of catalyst; the damp containing rate after setting is 8.5 percent; the baking temperature is 160 DEG C; and the baking time is 3 minutes. The finishing process utilizes the concentrated caustic soda to treat cotton/T400 fiber, thereby expanding cotton fiber molecule, increasing luster, improving appearance, improving the fixation force of anti-ultraviolet finishing agent, increasing washing resistance, endowing the T400 with elastic function, high water absorption and high moisture removing property.
