Methods of making and using elastic fiber containing an anti-tack additive

A process for using an elastic fiber comprising:

• (a) preparing a composition including at least one polyurethane, polyurethaneurea, or a mixture thereof;
• (b) adding to the composition about 0.1% to less than 0.5% by weight of a soluble anti-tack composition;
• and
• (c) preparing the fiber from the composition by a spinning process, wherein the yarn spinning breaks are reduced by about 20% or more relative to a fiber that does not include the anti-tack composition,
• wherein said soluble anti-tack composition includes a cellulose ester selected from the group consisting of cellulose acetate butyrate, cellulose acetate propionate, and a mixture thereof.
