Cleaning of spin packs, spinnerets

The gentle and repeatable cleaning of complete spin packs and spinnerets / spin nozzles is an important factor for fiber production, as this not only ensures a proper production process, but also a long lifetime for these key production tools.

Depending on the type of polymer (PE, PET, PA, PP, Spandex) and the design of the spin pack, the spin pack can be cleaned without requiring disassembly. Polymers are removed in a single step. Complete spin packs can be easily removed after cleaning. Inorganic remnants are removed using a select after-treatment method such as ultrasound.

The INNOVACLEAN cleaning system, for example, needs three to six hours to complete the cleaning process at temperatures between 450 °C and 480 °C. INNOVACLEAN can be used with most nozzle geometries and even with critical capillary sizes. The cleaning system eliminates any risk of thermal or mechanical damage to the spin nozzles.

CLEANING OF SPIN PUMPS

The gentle and repeatable cleaning of complete spin pumps is an important factor for fiber production and ensures a long lifetime for these machine components.

The spin pumps can be cleaned without requiring disassembly. Polymers are removed in a single step. Complete spin pumps can be easily removed after cleaning. Inorganic remnants are removed using a select after-treatment method such as ultrasound.

The INNOVACLEAN cleaning system, for example, needs three to six hours to complete the cleaning process at temperatures between 450 °C and 480 °C. INNOVACLEAN and VACUCLEAN can be used with most melt pumps – from small spin pumps to large booster pumps. The cleaning system eliminates any risk of thermal or mechanical damage to the pumps.

Cleaning of melt lines

Proper melt distribution in spinning systems is critical, as the pipes are often several meters long and have complicated geometries. The already difficult maintenance and servicing of these components, which are important for the quality of the product, is made even more difficult when integrated, static mixers are used.

The MAXICLEAN thermal cleaning systems made by SCHWING, featuring customer-specific cleaning chamber sizes and integrated afterburning, are just as efficient as they are effective. Polymers and their decomposition products are removed in a single step during the thermal cleaning process. Inorganic remnants are removed using a select after-treatment method. A thermally cleaned melt line is just like new in terms of its flow properties.

Of course, other components in the fiber production facility such as extrusion screws, melt pumps, etc. can also be cleaned with the MAXICLEAN cleaning system. The fluidized bed system INNOVACLEAN or the vacuum system VACUCLEAN are used for spin packs and nozzles guaranteeing optimal cleaning even with very critical capillary sizes or geometries.
