The TPU monofilament of this invention has high tenacity, high modulus, low tensile elongation, and low thermal shrinkage and its intended application is in industrial fabrics, especially in paper machine clothing (PMC). To ensure good adhesion properties of the silver layer, the PEEK mono filament surface is treated with an atmospheric pressure plasma. The flexibility of FDM makes it an attractive manufacturing technique. 1 depicts the non-limiting preferred procedure followed in producing the inventive thermoplastic monofilament fibers.
