International technology Group Andritz has extended its weight profiling product range – comprising ProDyn and ProWid – by ProWin. This is one of the steps the company has taken towards optimisation 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.

These are decisive factors in enabling nonwovens producers to offer competitive and sustainable products. As a world market leader for nonwovens production equipment and services, Andritz offers a full range of products to meet these challenging demands.

Maximising the evenness of the product across the entire production line is one of the key success factors. The weight profiling product range of Andritz – consisting of ProDyn and ProWid – has been extended by ProWin. This new development is the combination of the two existing systems ProDyn and ProWid. It allows nonwovens producers to achieve optimum weight profiling at the crosslapper delivery and increase their process speed by up to 15 per cent at the same time. ProWin combines the long-term process experience and in-depth knowledge Andritz has on needlepunch lines with innovative software to synchronise action across the line.

Guillaume Julien, head of Needlepunch Sales at Andritz Nonwoven, explains, “We have developed a self-regulating, advanced technology to reduce fibre deposits at the edges of the web and eliminate the “smile” effect across its width. ProWin enables producers to optimise the CV ratio autonomously and precisely while also generating significant fibre savings of up to 10 per cent 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 fibres, this set-up is designed to produce an even web with significant bulkiness and an excellent MD:CD ratio without impacting the production capacity.

Maximising performance by minimising the raw material input and the amount of waste produced is a real driver of cost optimisation. 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 fibres. 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.

Andritz also offers – under the brand Metris – Andritz digital solutions – a variety of 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. Thanks to this Metris application, Andritz customers are able to optimise their system’s consumption of raw materials.
