Electrically conductive thermoplastic fibers are made by spinning a fiber having an electrically conductive sheath of thermoplastic polymer formulated with carbon black and a non-conductive core from the thermoplastic polymer; quenching the fiber after said spinning to a temperature below the melting point of the thermoplastic; drawing the quenched fiber at a draw ratio between about 2. 0 and about 3. 2; and, after drawing, relaxing the fiber at a temperature below the melting point of the thermoplastic but above its glass transition.

A napped textile product is prepared by supplying a polyethylene terephthalate homopolymer yarn having an elongation of from about 20% to about 80%, a tenacity of from about 2. 5 to about 3. 5 grams/denier, and a boiling water shrinkage of from about 2% to about 15%; (b) forming a fabric from the yarn, so that substantially all yarn is the polyester yarn supplied in step (a); and (c) providing the fabric prepared in step (b) to a napping machine.
