Abstract: A wellness and/or heat blanket has autonomous, optically conductive fibers which are present in a proportion of 40 g/m2 or less, preferably 37 g/m2 or less and in particular approximately 35 g/m2 and/or which constitute a weight proportion of less than 15%, preferably less than 10% and in particular 8% or less.

Abstract: A piece of woven fabric cut to production size for the manufacture of articles of work clothing for protection from heat, flames, and electric arc effect is characterized by a 3/1 frame casing having approximately 36 threads per centimeter of chain and approximately 23 threads per centimeter of weft. The overall mixtures of chain yarn and weft yarn are approximately 41 percent viscose, approximately 30 percent to 41 percent meta-aramide, approximately 17 percent to 29 percent paramide, and approximately 1 percent polyamide with a carbon core, and by doubled yarns with count No. 40/2.
