SYNTHETIC FIBER CAPABLE OF ABSORBING AND DISABSORBING MOISTURE, ENTANGLED AND MIXED YARN USING THE SAME, KNITTED AND WOVEN FABRICS USING THE SAME, AND NONWOVEN FABRICS USING THE SAME
SYNTHETIC FIBER CAPABLE OF ABSORBING AND DISABSORBING MOISTURE, ENTANGLED AND MIXED YARN USING THE SAME, KNITTED AND WOVEN FABRICS USING THE SAME, AND NONWOVEN FABRICS USING THE SAME
A synthetic fiber capable of absorbing and disabsorbing moisture comprising a component capable of absorbing and disabsorbing moisture and a fiber-forming polymer. The fiber of the present invention has a moisture absorption of 1.5% or more when it is allowed to reach a moisture equilibrium under the circumstance of 25 DEG C x 60%RH and then is allowed to stand for 30 min. under the circumstance of 34 DEG C x 90 %RH, and has a moisture disabsorption of 2% or more when it is allowed to reach a moisture equilibrium under the circumstance of 34 DEG C x 90%RH and then is allowed to stand for 30 min. under the circumstance of 25 DEG C x 60%RH. The fiber also has a value of -1 to 5 in terms of b value in the CIE-LAB color system when it is allowed to stand for 30 days.
