PA3000 elliptical cylinder pre-needler among recent developments.

Innovation in Textiles  |  Graz, Austria

At ITME 2022 in Greater Noida, India, from December 8-13, Andritz will present its full product portfolio.

This now covers both nonwovens and textile production technologies, including air-through bonding, airlay, needlepunch, spunlace, spunbond, wetlaid/Wetlace, converting, textile finishing, recycling and natural fibre processing.

With the acquisition of Laroche, Andritz has expanded its product portfolio to include airlay and recycling technology as well as bast fibre processing technologies. Complete recycling lines for post-consumer and industrial textile waste to produce fibres for respinning and/or nonwoven end-uses are one focus of this product range. Customer awareness and regulations are forcing clothing brands to recycle their textile waste in their products. Recycled fibres can also be used in several nonwoven processes such as airlay in the automotive industry, for insulation, mattresses, and furniture felts.

The strong increase of nonwovens in the automotive sector in recent years has also opened up new opportunities in the filtration industry. Based on decades of experience, Andritz develops cost-efficient and reliable turnkey needlepunch and airlay lines.

The recent boom in the market for durable nonwoven products led Andritz to develop its PA3000 elliptical cylinder pre-needler to meet the demand for higher capacities and lighter products. It consists of an optimised cylinder pre-needler for the production of light batts in up to 6.75 metre widths and provides greater speed – up to 18m/min depending on the desired width. As a result the web layers are stitched together with optimum cohesion to maintain the web surface evenness, minimising the risk of cloud formation, as is the case with other pre-needler designs.

In addition, the automotive industry is shifting its focus to sustainable technologies, and this has a direct impact on the properties of nonwoven parts in vehicles. Andritz SDV2+2 double velour needleloom process composite velour fabrics that are latex free.

Airlay technology also plays a major role in durable nonwovens.

Lines have been designed to form mats from all types of fibres, from short and recycled fibres to long and coarse natural fibres,

Andritz offers various nonwoven processes to produce the best and most cost-effective wipes, like spunlace, Wetlace and Wetlace CP. Andritz also accompanies nonwoven producers in the move to sustainability with the aim of reducing or eliminating plastic components while maintaining the high quality of the desired product properties. This applies to all types of sustainable wipes, such as flushable, biodegradable, bio-sourced, carded-pulp or standard carded wipes. The latest development in this field is the Andritz neXline wetlace CP line, which integrates the card-pulp (CP) process. This is a fully engineered production line combining the benefits of drylaid and wetlaid technologies to produce a new generation of biodegradable wipes.

The Andritz teXcal Raconip TT calendar meanwhile sets new standards in textile processing for technical textiles, such as sportswear, workwear, canvas and parachute fabric,. It is aimed at customers who require versatility and operator-friendly handling along with excellent process stability in addition to constantly high manufacturing quality.

Its deflection-controlled roll – the Raconip – offers maximum flexibility thanks to unrestricted profiling across the entire fabric width by hydrostatic pistons. This guarantees the highest quality, such as absolute flatness and precise air permeability.
