| titleOfInvention | Process for the manufacture of flame-resistant and hydrophilic polyester fibers |
| abstract | Polyester fibers containing an oxalate complex of the general formula n n Me.sub.n [Z(C.sub.2 O.sub.4).sub.m ] n n are obtained by transesterification of terephthalic acid with ethylene glycol where, in addition to conventional transesterification catalysts, such as bivalent zinc, calcium, magnesium and manganese salts, salt formers are added which form a sparingly soluble salt or a complex with the cation of the transesterification catalyst. Preferably, used salt formers are: pelargonic acid, potassium hydrogen sulfate, potassium dihydrogen phosphate, potassium hydrogen phthalate, potassium oxalate, potassium carbonate, potassium hydrogen oxalate, and oxalic acid. In this way, the increase in pressure before the spinneret is considerably slowed down. |
