The present invention relates to polymeric compositions comprising the use of additives having the emission and / or absorption properties of radiation in the long wavelength infrared region, and also to articles made using the compositions. The present invention further relates to polymer compositions containing said additives and to methods of making yarns, and also to textile articles such as fabrics or knits made using said yarns, and also to their use. More particularly, the composition comprises an organic additive or inorganic filler having the ability to absorb / emit radiation in the infrared region in the wavelength range of 2 μm to 20 μm, and also a polymeric substrate, wherein the inorganic filler comprises oxides, sulfates, One or more types of inorganic fillers selected from carbonates, phosphates and silicates, with an average particle size of less than 2 μm. |
