Abstract
Polymer fibers having therein at least one infrared attenuating agent is provided. The infrared attenuating agent is at least substantially evenly distributed throughout the polymeric material forming the polymer fibers. In exemplary embodiments, the infrared attenuating agents have a thickness in at least one dimension of less than about 100 nanometers. Alternatively, the polymer fibers are bicomponent fibers formed of a core and a sheath substantially surrounding the core and the infrared attenuating agent is at least substantially evenly distributed throughout the sheath. The modified polymer fibers may be used to form insulation products that utilize less polymer material and subsequently reduce manufacturing costs. The insulation products formed with the modified polymers have improved thermal properties compared to insulation products formed of only non-modified polymer fibers. Additionally, the insulation product is compatible with bio-based binders. Methods of forming the modified polymer fibers and insulation products are also provided.
