From the Sector

International technology Group ANDRITZ has received an order from Pratrivero s.p.a. to supply a new eXcelle batt forming line for their production facilities in Valdilana, Italy. The line will be dedicated to the production of Maliwatt products, used in furnishing, automotive, naval, medical, geotextiles, advertising, clothing, and packaging applications. Installation and start-up are scheduled for the third quarter of 2021.

The ANDRITZ batt forming line includes an eXcelle card and eXcelle crosslapper, a ProDyn™ web profiling correction system as well as a scanning gauge with a closed loop. The ProDyn system combines actions from the card doffers with dynamic speed variation at the crosslapper. This will result in substantial fiber savings and reduction in CV%, providing improved weight evenness in the final product. The ProDyn closed loop will ensure the best possible self-regulation for the equipment and thus enable Pratrivero to produce one of the best product qualities on the market. Pratrivero will be the world’s first company to use the ProDyn technology in the Maliwatt stitchbonding process.

Stitchbond is a nonwoven process made by mechanically interlocking fiber webs with continuous filaments, thus imitating textiles. Stitchbonded products are used in many applications due to their lower production costs compared to woven textiles. Among all the different nonwoven processes in which it operates, ANDRITZ is also a market-leading supplier of batt forming equipment for the stitchbonding processes producing Maliwatt, Malivlies and quilting.

Pratrivero is an important player in the production of nonwoven fabrics using stitchbonding technology.

International technology Group ANDRITZ has always been at the forefront in providing innovative and sustainable solutions for the global nonwovens industry. 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.

As a world market leader for nonwovens production equipment and services, ANDRITZ offers a full range of products to meet these challenging demands.

Maximizing 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 ProDynTM and ProWidTM – has been extended by ProWinTM. This new development is the combination of the two existing systems ProDynTM and ProWidTM. It 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 combines the long-term process experience and in-depth knowledge ANDRITZ has on needlepunch lines with innovative software to synchronize action across the line. Guillaume Julien, Head of Needlepunch Sales at ANDRITZ Nonwoven, explains,

“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. ProWin enables producers to optimize the CV ratio autonomously and precisely while also generating significant fiber 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 fibers, 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 fiber 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 optimize their system’s consumption of raw materials.

All these innovations are available in ANDRITZ’s technical centers, where ANDRITZ process experts will be glad to welcome customers in order to discuss and define their product expectations.

International technology Group ANDRITZ has received an order to supply four new needlepunch lines for nonwoven production from Chongqing Double Elephant Microfiber Material Co., Ltd., China. These lines are scheduled for installation and start-up in the fourth quarter of 2021.

The needlepunch lines by ANDRITZ are designed to process islands-in-the-sea fibers dedicated mainly to the production of high-quality synthetic leather products. Once completed, the lines will produce 30 million meters a year of microfiber nonwoven materials.

The production lines are equipped with an ANDRITZ carding machine and the newly developed Profile® crosslapper as well as the advanced-technology ProWid closed-loop system from ANDRITZ. The system can monitor the weight uniformity (CV%) of the entire product online and predict the weight distribution changes caused by the bonding process. In addition, the web weight can be reduced by controlled stretching, which solves the issue of fiber accumulation at the edges caused by traditional crosslapping methods. Both the weight and the uniformity of the product can be automatically adjusted via the closed-loop function as set on the ANDRITZ gauge.

Chongqing Double Elephant Microfiber Material Co., Ltd., wholly owned by listed Wuxi Double Elephant Microfiber Materials Co., Ltd., is located in the Changshou National Economic and Technological Development Zone of Chongqing City. The company is active in the research, development and manufacture of microfiber materials, polyurethane synthetic leather and polyurethane resin.

International technology Group ANDRITZ has received an order to supply a neXline spunlace eXcelle line to Minet S.A, based in Ramnicu Valcéa, Romania, for processing various fibers from 25 to 70 gsm to produce a wide range of hygiene products. Start-up is expected during the second quarter of 2022.

ANDRITZ will deliver a complete line, from web forming to drying. The line will integrate one high-speed TT card, the robust Jetlace Essentiel hydroentanglement unit equipped with a neXecodry S1 system for energy saving, and a neXdry double-drum through-air dryer.

The close collaboration between ANDRITZ and Minet in needlepunch was an important consideration in the choice of supplier for the spunlace line as well as the fact that ANDRITZ is recognized as the benchmark for production of premium spunlace roll goods.

Just recently, ANDRITZ successfully completed the commissioning of a neXline needlepunch eXcelle line for Minet. This line is dedicated to the production of automotive products made from a large variety of fibers. For this contract, ANDRITZ delivered a complete line from fiber preparation to end-of-line, also integrating card, crosslapper, batt drafter, two needlelooms and a Zeta felt drafter with a working width of more than 6 m. The line is also equipped with the unique ProDyn web profiling system, operating as a closed-loop control system in order to ensure perfect evenness of the products.
