An implantable medical article as well as an implantable fiber which is particularly useful for medical implants is disclosed. The fiber includes comprises a first component formed from a substantially resorbable material and a second component formed from a fiber-forming polymer.

Implantable fibers and medical articles

The invention is a side by side nylon/nylon bicomponent yarn with desirable stretch and recovery and retractive force characteristics, and the process for manufacturing this yarn.

Elastic nylon yarns

Heatset, textured (e.g. stuffer box textured), continuous filament, nylon carpet yarn useful for making textured carpets is disclosed. The yarn is made from nylon 66 copolymer. Textured carpets made from the yarns of the invention have improved aesthetics and/or appearance retention characteristics as compared to textured carpets made from nylon 66 carpet yarns.

Copolymeric yarns for textured carpets

Drawing performance of a conjugated elastomeric polyurethane-hard polymer yarn is improved by critical stoichiometry in preparation of the polyurethane polymer, which is made by reacting together a high molecular weight diol, a low molecular weight diol, and a diisocyanate so that the resulting polyurethane contains between 1 and 45 (preferably between 1 and 27) microequivalents of free isocyanate groups per gram of polymer at the time of melt spinning.
