GRAZ - International technology Group Andritz has developed a new system aimed at helping its customers optimize their raw material consumption.
As Andritz notes, the optimization of resource management, especially reducing the consumption of raw materials and other substances used and also keeping resources in use for as long as possible, are decisive factors in enabling nonwovens producers to offer competitive and sustainable products.
A key factor here is the need to maximize the evenness of the product across the entire production line. With this in mind, the weight profiling product range from Andritz, which consists of ProDyn and ProWid, has now been extended with the addition of ProWin.
This new development, which is a combination of the two existing systems ProDyn and ProWid, allows nonwovens producers to achieve optimum weight profiling at the crosslapper delivery and increase their process speed by up to 15% at the same time.
ProWin also combines the long-term process experience and in-depth knowledge Andritz has on needlepunch lines with new software to synchronize action across the line (the image below shows the impact of the ProWin system on fibre distribution(.
“We have developed a self-regulating, advanced technology to reduce fiber deposits at the edges of the web and eliminate the “smile” effect across its width," explained Guillaume Julien, head of Needlepunch Sales at Andritz Nonwoven. "ProWin enables producers to optimize the CV ratio autonomously and precisely while also generating significant fibre savings of up to 10% and increasing production speed. Thus, it also provides a faster ROI.
"When it comes to the spunlace process, a better product quality can be obtained by ensuring that the different equipment units in the production line are consistent with one another. The TT card, the Jetlace hydroentanglement unit, and the neXdry through-air dryer are the perfect combination to obtain premium visual quality and characteristics in the web. For an equivalent amount of fibers, this set-up is designed to produce an even web with significant bulkiness and an excellent MD:CD ratio without impacting the production capacity.
"Maximizing performance by minimizing the raw material input and the amount of waste produced is a real driver of cost optimization. This is why Andritz has created and integrated a solution that allows nonwovens producers to retrieve the wasted edges of their spunlace fabric and re-use it as recycled fibers. As a result, roll-good producers can even obtain the same web characteristics as when using virgin fibres, and most importantly, the exact same quality."
Under its Metris brand, Andritz also offers a number of digital solutions including several service apps for optimum customer benefit.
The Metris Cost Management app is used to track raw material consumption. It is an advanced system aimed at monitoring fibre consumption and allowing in-depth diagnoses to investigate raw material losses and savings grouped by different process areas.
