Disclosed herein are spun yarns comprising melt spun staple fiber comprising a first polymer and a second polymer, wherein the first polymer comprises poly(trimethylene terephthalate) or poly(butylene terephthalate) and the second polymer comprises poly(ethylene terephthalate) or Co-PET, wherein Co-PET is a poly(ethylene terephthalate) copolymer comprising isophthalic acid monomer; and wherein the first polymer comprises poly(trimethylene terephthalate) and the weight ratio of the poly(trimethylene terephthalate) to the second polymer is in the range of from about 80:20 to about 10:90; or the the first polymer comprises poly(butylene terephthalate) and the weight ratio of the poly(butylene terephthalate) to the second polymer is in the range of about 90:10 to about 10:90. The spun yarn may further comprise a second staple fiber such as cotton or wool. The spun yarn is useful in preparing fabrics having advantageous properties.
