Abstract
The composite elastic yarn may be made from a wide, stretchable textile fabric or stretchable knitted fabric. A composite elastic yarn is obtained by drawing an elastic yarn 11 at a first draft rate to prepare a precursor composite elastic yarn with an inelastic yarn 31 and further drawing the precursor composite elastic yarn at a second draft rate of a value smaller than that of the first draft rate to make a composite with the removable inelastic yarn 31; and stretchable textile fabric and stretchable knitted fabric fabricated using this composite elastic yarn.
