Abstract
A swellable polymer based fiber and a method of preparing the same optionally comprising glycol, lecithin and optionally an antimicrobial metal species suitable, for example, for medical applications including wound dressings. A method of manufacture may comprise fiber extrusion or spinning involving one or a plurality of in-series coagulation baths to add single or multiple antimicrobial metal species to the as-formed fiber.
Claims10
A method of forming a swellable polymer based fibre comprising:
- creating an aqueous dope solution containing a water soluble polymer;
- spinning or extruding the dope solution into a coagulation bath to form an extruded fibre;
- drawing the fibre from the coagulation bath;
- adding a glycol to the dope solution, the glycol having between two to fifteen carbon atoms;
- and
- adding a lecithin to the dope solution.
