Harris Tweed any flaws. Once ready the cloth is finished. Dirt, oil and other impurities are removed by washing and beating in soda and soapy water before it is dried, steamed, pressed and cropped. The final process is the examination by the independent Harris Tweed Authority which visits the mills weekly, before application of their Orb Mark trademark which is ironed on to the fabric as a seal of authenticity. In 2012 the weavers and mills of the Harris Tweed industry produced one million metres of Harris Tweed, compared to 450,000 metres in 2009, which was the highest production figures in 17
Ceramic-impregnated fabric involve high temperatures. Ceramic-impregnated fabric Ceramic-impregnated fabric is a fabric that has been impregnated with ceramic. Nanometric bioceramic can be incorporated into the polymer from which the fabric is manufactured. Bioceramic nanoparticles are added to the fused polymer. Some types of ceramics show thermally-induced photoluminescence, emitting light in the far infrared (FIR) region of the electromagnetic spectrum. When in contact with the body heat, the thermoluminescence of the fabrics with embedded bioceramic is enhanced. Bioceramics presents high reflection coefficient for the infrared radiation. One way in which fabrics can be impregnated with ceramic is the process of electrophoretic deposition or
