Abstract
A functional elastic composite yarn comprises an elastic member that is surrounded by at least one functional covering filament(s). The functional covering filament has a length that is greater than the drafted length of the elastic member such that substantially all of an elongating stress imposed on the composite yarn is carried by the elastic member. The elastic composite yarn may further include an optional stress-bearing member surrounding the elastic member and the functional covering filament.
