Production of fibers

Beside natural fibers (bristles, fiber, goat hair), there are also used synthetic fibers in Spojené kartáčovny. These are mainly produced directly in the company on the automatic extrusion line Technoplastic (IT).

Produced polypropylene (PP) or polyester (PET) fibers may be straight or wavy and fissionable or nonfissionable. Maximum length of a bunch is 1200 mm. Hue according to customer´s request.

It is possible to use for production crude or recycled material.

Procedure during the production of synthetic fibers

  1. plastic granulate is melted at high temperature and pressure
  2. with the help of a screw it is extruded in the form of fiber into a tub with coolant. At this stage, the fiber does not have required characteristics (strength, flexibility, etc.)
  3. to improve its qualitative characteristics, the fiber passes through a system of tensioning cylinders, which stretch the fiber (the fiber gets thinner irreversibly, and it is also extended). Links between molecules are oriented in one direction, what results in improved features of the fiber
  4. The fiber is wound up and divided into bundles of necessary length
