Synthetic fibre, another name of plastic monofilament, including PP, PBT, PET, PE, PA monofilament. They are polyvinyl chloride, polyethylene, polypropylene or polyamide and other plastic melt extrusion from the extrusion die, after cooling, drafting, heat setting and winding the smaller diameter of the monofilament.
Polyester monofilament (PET): because the crystallinity is high, so monofilament is relatively white, relatively high strength, relatively speaking, relatively hard.
Nylon monofilament (PA): relatively low degree of crystallinity, the color is a bit transparent, but placed a long time will be high strength.
Polypropylene monofilament (PP): low crystallinity, color transparent, low strength, not hard.
