摘要：
The present invention provides a process for obtaining a fiber comprising the steps of:
melt extruding a mixture of a thermoplastic polymer and a hydrophilicity imparting compound A to form a plurality of filaments;
applying a spin finish to said filaments;
and spinning said filaments into a fiber;
characterised in that said spin finish comprises a fluorochemical oil and/or water repellent.
