Andritz Showing Innovative Nonwovens Solutions At Techtextil

International technology group Andritz will be presenting its innovative nonwovens production and textile solutions at Techtextil in Frankfurt in Hall 12, Stall B-93.

Andritz technologies cover air-through bonding, airlay, airlaid, needlepunch, spunlace, spunbond, wetlaid/Wetlace, converting, textile finishing, recycling, and natural fibre processing.

At Techtextil, Andritz will emphasise on technologies for textile sorting and recycling, bast fibre processing, needlepunch, airlay, wetlaid for technical fibers, and life-cycle service.

The latest development in the textile recycling area is the Andritz automated textile sorting process.

This process is the result of an ambitious partnership between textile recycling company Nouvelles Fibres Textiles, waste sorting specialist Pellenc ST, and Andritz, a specialist in textile recycling machinery and processes.

Capable of automatically sorting garments by composition and colour, the line meets the needs of both post-consumer and post-industrial waste markets.

In addition, Andritz is also focusing on processing ecofriendly bast fibres such as hemp, kenaf, jute, and others.

The company offers sophisticated solutions for decorticating bast fiber straw for further cottonising and respinning processes.

Another special focus area at Techtextil will be technologies for durable nonwovens. Andritz offers comprehensive processes in this market segment, such as needlepunch, airlay, and wetlaid.

For all these processes Andritz has dedicated technical centers, where customers are welcome to conduct trials and develop new products.

One highlight in the needlepunch sector is the new neXloom Elliptica-type DF-4 needleloom.

This machine makes it possible to process very lightweight nonwovens of 40 gsm at high-speed (>25 m/min) while at the same time ensuring that visual quality is given top priority.

Available in large widths, it provides optimised pre-needling consolidation to ensure an even visual appearance by reducing the drafting ratio by 30-50 percent in a first needleloom when producing very light felts.

Moreover, airlay technology also plays a major role in durable nonwovens, such as in the automotive industry, building insulation, carpet underfelt, the mattress industry, and furniture applications.

This process includes blending, fine opening, the airlay process, and finally mat consolidation, by needling, thermobonding, a combination of the two, and spunlacing.

It allows customers to process all types of fibres from virgin, recycled fibres to non-fibre particles such as foam, shredder paper, and straw.

This technology can guarantee homogeneity and mat regularity for a large range of weights from 300 to 1,200 gsm.

The airlay has optional 3D web forming equipment capable of producing multiple density web that is mostly adapted for the automotive industry.

In addition, Andritz wetlaid technology can efficiently process technical fibres such as carbon, metal, aramid, glass, and micro glass fibres or fibre blends for technical applications.

These types of fibers require gentle and customised treatment in the forming process.

For this reason, Andritz develops tailor-made wetlaid production lines for technical fibers and products, including a dedicated forming process.
