New finishing line for airbags at UTT
The challenge here is to implement the multiple technical requirements of the line concept. The aim of this project was the production of a high-performance airbag OPW fabric. Therefore a new process for the multi-stage in-line finishing of OPW fabric was developed. For continuous production, the line is equipped with the necessary elements for non-stop fabric change over. Brückner's stenter system is equipped with a newly developed indirect gas heating system. This system completely separates the circulating air of the dryer from the hot burner exhaust gases so that no contact between the sensitive fabric can occur. In addition, the system has an integrated heat-recovery system for heating up fresh air in order to achieve the highest possible energy efficiency. This heat-recovery system enables a saving of approx. 30 m³ of natural gas per hour for the entire system and significantly reduces CO2 emissions compared to other systems.
