POLYAMIDE SHEATH-CORE CONJUGATED FIBER HAVING EXCELLENT OPACITY, UV LIGHT-SHIELDING PROPERTY, HEAT-SHIELDING PROPERTY, MOISTURE-ABSORBING OR RELEASING PROPERTY, AND COLOR-DEVELOPING PROPERTY AND COVERING ELASTIC YARN AND BULKY PROCESSED YARN USING THE SAME
POLYAMIDE SHEATH-CORE CONJUGATED FIBER HAVING EXCELLENT OPACITY, UV LIGHT-SHIELDING PROPERTY, HEAT-SHIELDING PROPERTY, MOISTURE-ABSORBING OR RELEASING PROPERTY, AND COLOR-DEVELOPING PROPERTY AND COVERING ELASTIC YARN AND BULKY PROCESSED YARN USING THE SAME
PROBLEM TO BE SOLVED: To provide a polyamide sheath-core conjugated fiber having excellent opacity, UV light-shielding property, heat-shielding property, and moisture-absorbing or releasing property, little worsening a color-developing property, when dyed, and having an excellent color tone.;SOLUTION: This polyamide sheath-core conjugated fiber comprising an opaque white polyamide polymer layer having a white pigment content of 6 to 30 wt. % and a transparent polyamide polymer layer having a white pigment content of 0 to 1 wt. % and a moisture absorbent content of 3 to 15 wt. % is characterized by having a fiber cross section conjugated structure in which the transparent layer is divided into three or more layers with the opaque white layers and occupies 50 % of the fiber surface and having a light-transmitting transparent layer portion at a rate () of 50 % based on the total area of the fiber cross section.;COPYRIGHT: (C)2006,JPO&NCIPI
