Abstract:
A blended yarn comprising:a first set of fibers selected from the group consisting of cotton, rayon, polypropylene and polyester having 0% to about 2% polyethylene glycol; and polyester staple fibers formed from a polyester composition consisting essentially of; polyethylene terephthalate; and polyethylene glycol in an amount sufficient to increase the wetting and wicking properties of a filament made from the composition to a level substantially similar to the wetting and wicking properties of cotton but less than the amount that would reduce the favorable elastic memory properties of the polyester composition, said amount being greater than about 4 percent up to about 20 percent by weight based upon the weight of the composition; and pentaerythritol in an amount that raises the melt viscosity of the polyester composition to a level that permits filament manufacture with said amount of said polyethylene glycol and under conditions that are substantially the same as those under which filament can be formed from unmodified polyethylene terephthalate.
