Abstract

PURPOSE: To produce a thick and thin textured yarn for clothes comprising polyester incompletely drawn fibers having thick parts and thin parts in the longitudinal direction, having a difference in light and shade of dyeing and excellent in bulkiness and quality. CONSTITUTION: This thick and thin textured yarn comprises polyester incompletely drawn fibers prepared by drawing an undrawn polyester yarn having 20 to 35×10<-3> birefringence ratio at 45-55% of the maximal draw ratio A=[(breaking elongation + 100)/100]×1.05 of the undrawn yarn while bringing the undrawn yarn into contact with a heating unit at 50-150 deg.C and then subjecting the drawn yarn to simultaneous draw false twisting and having 3-5% U%, 10-22C index (a value obtained by dividing the number of points crossing the center line C counted for 4 m yarn length in a chart in measurement with an evenness tester by 4) and 40-60 S index a value obtained by determining an area S of a part indicating deep color parts for 25 cm in a U% chart and further obtaining the ratio [S/(L×1)] in percentage). The yarn has deep colored parts and light-colored parts in a ratio of the same extent and providing a moire finish with a moderately calm difference of light and shade as a thick and thin yarn.
