CLOTH HAVING EXCELLENT MOISTURE ABSORPTIVITY AND COLOR FASTNESS AND ITS PRODUCTION

Japanese Patent JP3284851

B2

PROBLEM TO BE SOLVED: To obtain a cloth having a moisture-absorptivity, dry-touch and high color fastness sufficient for comfortable wearing by using a sheath-core conjugate fiber containing a moisture-absorbing polymer as the core and having a hollow part at the interface between the core part and the sheath part.
SOLUTION: A moisture-absorbing cloth having excellent color fastness is produced by forming a sheath-core conjugate fiber composed of a core part containing <20wt.% (based on the core part) of a moisture-absorbing polymer consisting of a polyether ester having a swelling degree of ≤3.2 in water at 20°C or a blend of the polyether ester and a thermoplastic polymer such as a polyester or a nylon and a sheath part composed of a polyester and having a thickness of ≥4.3μm, subjecting the conjugate fiber to dry-heat treatment at a temperature above the melting point of the core polymer and below the melting point of the sheath polymer to form a hollow part at the interface between the core part and the sheath part at a hollowness percentage of ≥1.4%. weaving or knitting the conjugate fiber and dyeing the produced woven or knit fabric.
