Cool Black applications in synthetic fibers

Grafe has recently launched a new combination of colourants that will significantly reduce the heating up of PA and PET surfaces caused by the thermal absorption of carbon pigments. This temperature minimizing effect is also known under the name "cool black".
The solution is available as masterbatch and can dye PA and PET yarns with a dark colour. The special colouration guarantees that thermal radiation (in the near infrared area) can only be absorbed up to 700 nm.
The reduced thermal absorption means that the product's surface is perceived as much cooler and more pleasant to touch. Due to the chemical compatibility of the colourants used in PA and PET, company's experts have also found a way to create an alternative formulation for PP with the same effect.
The new product development has been created for manufacturers of textiles and other semi-finished products made of synthetic yarns who are interested in a simpler and more economical and cost-effective alternative to existing cool black products. Applications are in the field of smart-textiles, covers, floor mats and upholstery fabrics for seats in the automotive industry as well as in building interiors with increased exposure to sun.
