Abstract
The invention provides a method of treating fabrics containing polyetherester fibers so that the fabrics retain their basis weight, power, and stretch without edge curl. Fabrics containing polyetherester fibers are heat-set after dyeing, preferably in a temperature range of 160-180° C. (dry) or 115-140° C. (steam).
Claims5
A method of treating fabric comprising the sequential steps of:
- (a) preparing a fabric comprising polyetherester fiber wherein said polyetherester fiber is prepared from poly(tetramethylene-co-2-methyltetramethyleneether)glycol;
- 1,4-butanediol, and dimethyl terephthalate;
- (b) dyeing said polyetherester fabric;
- and
- (c) heat-setting said dyed polyetherester fabric;
- wherein said fabric is dry heat-set at 171-180° C. for 10-60 seconds.
