In textile finishing, singeing plays an important role in preparing fabric for the next stage of production. The process uses a controlled flame to burn off fine fibers and hairiness sticking out from the fabric surface. By removing these unwanted fibers, the fabric becomes smoother, cleaner, and more refined, giving it a more premium look and feel.
However, achieving consistent singeing results is not always easy. The flame needs to be strong enough to remove surface fibers, but also controlled enough to avoid damaging the fabric. Uneven flame distribution can lead to inconsistent results across the fabric width, while excessive heat may cause thermal damage. At the same time, maintaining good singeing performance without using too much gas remains a key challenge for textile manufacturers.
Advanced Burner Technology for Quality and Efficiency
Benninger SingeRay combines high-efficiency burners with a stainless-steel nozzle strip featuring two rows of high-velocity nozzles. This advanced design generates a high-energy-density flame that is evenly distributed across the entire burner width, supporting uniform singeing effects and consistent fabric quality. The high gas flow velocity also helps minimize nozzle clogging, reducing the impact of potential blockages on flame uniformity. By delivering efficient flame performance with lower gas consumption, the technology helps textile manufacturers reduce operating costs, minimize uneven singeing, and improve fabric finishing quality.
Smart Cooling and Heating for Reliable Burner Performance
Benninger SingeRay features an advanced preheating and cooling system with plate heat exchangers operating in two closed circuits. Its dual cooling system helps maintain uniform burner temperature from machine start-up to the end of production, preventing burner deformation under normal operating conditions. The system also helps prevent condensate formation on cooling rollers during start-up and scaling caused by calcium and magnesium deposits in the cooling rollers and circuits. In addition, heat recovery for process water is possible, helping improve utility efficiency. By maintaining stable operating temperatures and reducing maintenance requirements, the system supports consistent singeing quality, lower second-grade production, higher machine utilisation, and longer equipment life.
Automated Control for Customised Singeing Results
Benninger SingeRay features individual gas pressure adjustment for each burner, ranging from 2 to 20 mbar through separate gas-air mixing and regulating devices. This allows manufacturers to customise singeing intensity on the face and back sides of the fabric according to specific finishing requirements, such as applying less singeing to the back of fabrics intended for raising or stronger singeing on the face of satin fabrics.
Additionally, its automatic flame-width adjustment uses step motors to close unused burner sections based on the required fabric width, which can be set through the HMI or determined by a fabric-width detection sensor. This enables efficient processing of narrower fabrics, ensures the flame is applied only where needed, and helps achieve significant gas savings while maintaining consistent singeing performance.
With Benninger SingeRay, textile manufacturers can achieve consistent fabric quality through uniform flame distribution from high-velocity nozzles, improve gas efficiency and reduce operating costs with automatic flame-width adjustment, and minimize maintenance requirements through smart cooling that helps prevent burner deformation and supports longer product life. Automated process parameter settings and adjustable singeing intensity further enable repeatable operating conditions, while the high-velocity nozzle system is designed to support lower emissions.
These benefits help manufacturers address key production challenges while balancing finishing quality with operational efficiency and the result is a more controlled and efficient approach to fabric singeing.
