Abstract (en)
[origin: WO2015074651A1] The invention relates to a process for producing a friction-reducing coating made of a yarn produced from a synthetic polymer matrix chemically bonded with a polyfluorinated hydrocarbon and of a hardenable resin matrix with at least the following process steps: the polyfluorinated hydrocarbon is activated by means of high-energy irradiation with formation of reactive functional groups, the activated polyfluorinated hydrocarbon is reacted chemically with the synthetic polymer component in a reactive extrusion process to give a substrate in the form of granules, filaments are produced from the substrate by means of a spinning process, a multiplicity of filaments are spun to give a yarn, a resin-saturated textile product is produced from the yarn and the resin matrix, and is hardened to give a semifinished product, and the friction-reducing coating is produced from the semifinished product by subsequent final shaping.
