a woven fabric selected from the group consisting of plain, twill and satin construction, comprising:

a plurality of weft yarns and a plurality of warp yarns,

wherein from about 15 to about 55 weight percent of the warp yarns are polyester bicomponent continuous filaments comprising poly(ethylene terephthalate) and poly(trimethylene terephthalate) and having an after-heat-set crimp contraction value from about 20% to about 80%, and polyester bicomponent continuous filaments are present in both the warp yarns and the weft yarns.

2. A fabric comprising:

a woven fabric selected from the group consisting of plain, twill and satin construction, comprising:

a plurality of weft yarns and a plurality of warp yarns,

wherein from about 5 to about 60 weight percent of the fabric weight comprises polyester bicomponent continuous filaments comprising poly(ethylene terephthalate) and poly(trimethylene terephthalate) and having an after-heat-set crimp contraction value from about 20% to about 80%.

3. The fabric of claim 2 , wherein said fabric comprises polyester bicomponent continuous filaments from about 20 to about 40 weight percent of the fabric weight.

4. The fabric of claim 2 , wherein both of said weft yarns and said warp yarns comprise polyester bicomponent continuous filaments.

5. The fabric of claim 2 , wherein from about 15 to about 55 weight percent of the warp yarns are polyester bicomponent continuous filaments.

6. The fabric according to claim 2 , wherein from about 22 to about 33 weight percent of the warp yarns are polyester bicomponent continuous filaments.

7. The fabric of claim 2 , comprising from about 13 weight percent to about 19 weight percent polyester bicomponent yarns, based on total fabric weight.

8. A fabric comprising:

a woven fabric comprising a plurality of weft yarns and a plurality of warp yarns, wherein said warp yarns and optionally said weft yarns comprise about 15 to about 55 weight percent polyester bicomponent continuous filament in the form of a corespun multi-component yarn; said polyester bicomponent filament comprising poly(ethylene terephthalate) and poly(trimethylene terephthalate).

9. The fabric of claim 8 , wherein said polyester continuous filament has an after-heat-set crimp contraction value from about 20% to about 80%.

10. The fabric of claim 8 , wherein both said warp yarns and said weft yarns comprise bicomponent polyester continuous filaments.
