ANDRITZ announces that it will supply a new eXcelle batt forming line to Pratrivero s.
p.a. for their Maliwatt production facilities in Valdilana, Italy. Maliwatt products are used in furnishing, automotive, naval, medical, geotextiles, advertising, clothing, and packaging applications. Installation and start-up are scheduled for the third quarter of 2021.
Stitch-bond 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 fabrics. Among all the different nonwoven processes in which it operates, ANDRITZ is also a market-leading supplier of batt forming equipment for the stitch-bonding processes producing Maliwatt, Malivlies, and quilting.
Pratrivero has trusted in ANDRITZ once again because of its reputation regarding process expertise and the high level of carding and cross-lapping technology involved. The company already operates several ANDRITZ eXcelle batt forming units.
Pratrivero is an important player in the production of nonwoven fabrics using stitch-bonding technology. The company has several plants in Italy and the USA, producing different types of stitch-bonded products. The centuries-old tradition of the Italian company, founded in 1663, combined with modern technology, has enabled Pratrivero to bring stitch-bonding to a high-end quality level with unique characteristics.
The ANDRITZ batt forming line includes an eXcelle card and eXcelle cross-lapper, a ProDyn™ web profiling correction system, and a scanning gauge with a closed-loop.
The ProDyn system combines actions from the card doffers with dynamic speed variation at the cross-lapper. 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 stitch-bonding process.
