first polymer surrounded by the compatibilizer that is dispersed in the polymer matrix of the second polymer in a practical implementation a so called master batch including granulate of the first polymer and the compatibilizer is formed the master batch may also be referred to as a u201c polymer mixture u201d herein the granulate mix is melted and a mixture of the first polymer and the compatibilizer is formed by extrusion the resulting strands are crushed into granulate the resultant granulate and granulate of the second polymer are then used in a second extrusion to produce the thick fiber which is then stretched into the final fiber the melt temperature used during extrusions is dependent upon the type of polymers and compatibilizer that is used however the melt temperature is typically between 230 u00b0 c and 280 u00b0 c a monofilament which can also be referred to as a filament or fibrillated tape is produced by feeding the mixture into an fiber producing extrusion line the melt mixture is passing the extrusion tool i e a spinneret plate or a wide slot nozzle forming the melt flow into a filament or tape form is quenched or cooled in a water spin bath dried and stretched by passing rotating heated godets with different rotational speed and or a heating oven the monofilament or type is then annealed online in a second step passing a further heating oven and or set of heated godets by.
