Abstract
IR-emitting or reflecting polymer fibers are formed by blending a high concentration of IR-emitting or reflecting particles with a thermoplastic polymer and meltblowing fibers which have an average diameter of 20 μ or less. The meltblowing process allows for inclusion of a high concentration of the IR-emitting or reflecting particles, yet allows fibers to be formed. These can be formed into a soft, air-permeable, nonwoven web. The fibers can be monocomponent or bicomponent or multicomponent and can be textured or shaped.
