PROCEDE D'OBTENTION DES FIBRES POLYESTERIQUES PEINTE EN MSSE

The process comprises filtration of the pigmented PTFE granule melt e.g. in the polycondensation state. The pigment : granule ratio is 1-3/100, and the polymer filaments are drawn at 88+-5 per cent m/minute, with antistatic treatment. Further treatment is followed by drawing at 4.20-4.40, at a press...

Zusammenfassung:	The process comprises filtration of the pigmented PTFE granule melt e.g. in the polycondensation state. The pigment : granule ratio is 1-3/100, and the polymer filaments are drawn at 88+-5 per cent m/minute, with antistatic treatment. Further treatment is followed by drawing at 4.20-4.40, at a pressure of 250-350 kg, with fixing using hot air at 145-155 degrees C over a distance of 16 m.
