Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyester multifilament conjugated yarn thread simultaneously having satisfactory soft and dry feelings, having suitable puffiness and firmness, further having resilience, and therefore suitably used for women's wear. SOLUTION: This polyester multifilament conjugated yarn thread is formed by paralleling or combining (A) polyester multifilament undrawn yarn and (B) polyester multifilament drawn yarn, wherein the polyester multifilament undrawn yarn (A) has a degree of crystallinity (Xρ) of ≤ 20%, a shrinkage percentage on heating and drying (SHD) of less than 0%, and such characteristics measured by a dynamic viscoelastic method that a temperature (Tα) at which primary dispersion is observed is in a range of 90-125°C and a maximum dynamic dissipation factor [(tanδ)max] is in a range of 0.20-0.30, and the polyester multifilament drawn yarn (B) has a shrinkage percentage in hot water (SHW) of 5.0-60% and a SHD of 7.0-80%.
