Abstract
PURPOSE: To obtain a covered elastic yarn which alternately has blended portions and interlaced portions free from irregular thickness in the longitudinal direction and further has the interlaced portions exhibiting twisted inflection points under a tension-free condition by blending and interlacing a false-twisted crimped yarn with an elastic yarn having a specific draft rate. CONSTITUTION: An elastic yarn (preferably a polyurethane yarn) 3 is drafted at a draft rate of 5-70% between draft rollers 8 and 9 and at a draft rate of >=100% between the draft rollers 9 and a draft roller 10, subjected to draft rate reduction of >=5%, and then fed into an interlacing nozzle 11. In the interlacing nozzle 11, the fed elastic yarn 3 is blended and interlaced with an independently fed false-twisted crimped yarn (preferably a nylon filament yarn) 4 to form the covered elastic yarn. The covered elastic yarn does not have irregular thickness in the longitudinal direction, alternately has blended portions and interlaced portions, has the interlaced portions each exhibiting a twisted inflection point 1 which is generated by the integral behaviors of the elastic yarn 3 with the false-twisted crimped yarn 4 under a tension-free condition, and has an uniform appearance, an improved interlacing number and an improved interlacing strength.
