Abstract:
1. An electrically conductive elastic composite yarn comprising: at least one elastic member having a relaxed unit length L and a drafted length of N×L, wherein N is in the range of about 1.0 to about 8.0, at least one conductive covering filament surrounding the elastic member, the conductive covering filament having 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, and a stress-bearing member surrounding the elastic member, and wherein the stress-bearing member has a total length less than the length of the conductive covering filament and greater than, or equal to, the drafted length (N×L) of the elastic member, such that a portion of the elongating stress imposed on the composite yarn is carried by the stress-bearing member.
