Plastic Extrusion Research – Threads

Am starting to do some research for a sustainability project where recycled plastics would be used in clothing. Not looking at high fashion, but every-day, wearable items.
Basically, how thin/long can plastics be extruded, and can we create threads for weaving and sewing with the types of plastics we find in disposable water bottles and the such? I know nylon is a type of plastic, but how would other types do?


Plastic bottles can be recycled into polyester clothing. I think there is an additional chemical step involved, not just melting and extruding.

it could definitely be done, but the equipment required to make a uniformly sized thread would be very expensive. check this following video:
