During the manufacturing of monofilaments, polymers are plasticized and pressed through a die. The resulting continuous filaments are stretched to achieve the desired properties. The development from raw material to monofilament takes place on a monofilament production line. Some of the finished products can be artificial turf, tennis strings, brushes or fishing lines.
In this process heat is needed, because of this water or cooling liquids are also needed to clean and cool down the filaments.
Cellulose sponge is used at the end of the line to absorb and wipe off the excess liquids.
