摘要

Cleaning granulates from Dreychem are being used by IFG Asota to clean its extrusion equipment to help ensure that it produces high-quality fibres from biopolymers. IFG Asota of Linz, Austria, is a research and development (R&D) centre operated by Industrial Fibres Group (IFG; see also, page 11, which has its headquarters in Danderyd, Sweden, and manufactures meltspun staple fibres from polypropylene (PP), polyethylene (PE) and polyamide (PA). The products manufactured on the pilot plant installed at IFG Asota change often, meaning that the extruders need to be cleaned frequently between production runs. R&D Manager at IFG Asota, Andreas Weinberger, says: "With the fibre diameters down to less than 20 μm, even the tiniest contaminants in the melt can cause production problems. Especially when the machine has been idle for a certain time, rinsing with the usual polymer is not enough to reliably remove all the deposits and agglomerates". He adds that this is particularly the case if biopolymers, such as polylactic acid (PLA), are being processed, as they tend to degrade rapidly at elevated temperatures. Weinberger uses Dreyclean LT cleaning granulates from Dreychem of Moormerland, Germany, for the task. He says that they have proved to be so efficient that, "since we started using them, we have had significantly fewer problems such as fibre breakages. Apart from that, our experience shows that, following their use, processing temperatures in the extruder of up to 20°C lower are sufficient for achieving the same throughput. This improves the quality of the bio-based fibres and lowers the energy consumption."
