PROBLEM TO BE SOLVED: To obtain a fiber which comprises a temperature-regulating and humidity-controlling highly hygroscopic fiber having controlled moisture absorbing and releasing rate, has regulating functions such as pH adjusting properties, flame retardance, antimicrobial properties, deodorizing properties, pilling resistance, antistatic properties, water retention, water sucking up properties, readily drying, etc., and also health/pleasantness/safety/sanitation/easy care. SOLUTION: This hygroscopic cross-linkable acrylic fiber has temperature- regulating and humidity-controlling function of 15-35wt.% saturated moisture absorption at 20 deg.C at 65% RH, 0.015-0.029 coefficient of moisture absorption rate K1 of the formula, W1 =We (1-e<k1t> ) [wherein W1 is moisture absorption ratio at time (t) from an absolute dry state; We is saturated moisture absorption ratio at 20 deg.C at 65% RH; K1 is coefficient of moisture absorption rate, and (t) is 0-30 minutes] and 0.005-0.015 coefficient of moisture releasing rate K2 of the formula, W2 =(Wa -Wb ) (1-e<-k2t> ) [W2 is moisture absorption ratio at time (t) form Wb ; Wa is saturated absorption ratio at 20 deg.C at 30% RH; Wb is saturated moisture absorption ratio at 20 deg.C at 80% RH; K2 is coefficient of moisture releasing rate, and (t) is 0-30 minutes]. |
