Abstract:
A heat-retaining, moisture-permeable, waterproof fabric having a highly moisture-absorbing and releasing organic fine particles immobilized on at least one surface of an unprocessed fabric (base fabric) with a moisture-permeable waterproof resin, said fabric (processed fabric) being capable of achieving a difference in the hygroscopic degree (.DELTA.A) as represented by the following equation (1) and a difference in the temperature of heat generated by absorption of moisture (.DELTA.T) as represented by the following equation (2):.DELTA.A=A (95)-A (20).gtoreq.3 (%) (1)wherein A (95) represents a moisture absorption ratio (%) of the processed fabric as measured after being left to stand for 24 hours at a relative humidity of 95% (20.degree. C.), and A (20) represents a moisture absorption ratio (%) of the processed fabric as measured after being left to stand for 24 hours at a relative humidity of 20% (20.degree. C.); and.DELTA.T=T (sample)-T (blank).gtoreq.0.5 (.degree.C.) (2)wherein T (sample) represents the surface temperature of the processed fabric as measured after the fabric is absolutely dried, adjusted to a temperature of 32.degree. C. in an absolute dry condition and held for 10 seconds in an environment of 70% RH and 32.degree. C., and T (blank) represents the surface temperature of the unprocessed fabric (base fabric) as measured after the fabric is absolutely dried, adjusted to a temperature of 32.degree. C. in an absolute dry condition and held for 10 seconds in an environment of 70% RH and 32.degree. C.
