Oil-free compressed air means more efficient production, reduced repair and maintenance costs, and improved product quality with less wastage.
Compressed air is blown through fine nozzles to transport the weft. Oil in the air blocks the nozzles, leading to production stoppages and costly nozzle replacements. Fabric staining will also result, causing product rejections.
Exhaust air from the nozzles blows over the air-jet weaving machines. Any oil present deposits on the reeds. It attracts dust and fibres causing the reeds to stick together and break. Resulting production losses and reed replacements are very expensive.
Cotton is spun into yarn using compressed air through fine nozzles. Oil in compressed air will lead to nozzle clogging. It will also stain the yarn, which is in direct contact with the compressed air. Expensive nozzle replacements, production losses and product rejections will result.
In this process, yarn is intermingled using a jet of air through a nozzle. Blockage due to oil will cause uneven intermingling and destroy the yarn. Staining of the yarn will also result.
The production of manmade raw materials for use in textiles also uses compressed air. One of the applications is the pneumatic transport of PVC, PTA or DMT chips. Oil contamination can cause substandard products besides being a fire hazard. Oil may also damage controls and instrumentation components, resulting in breakdowns.
