Environmental news and technical  innovation in the nonwovens sector

CLEVELAND - Demand for nonwovens used in filtration applications is projected to climb by 2.7% per year to US$1.5 billion in 2024 driven, in part, by the ongoing development of advanced nanofibre technologies.

A new report from the Freedonia Group notes that nanofibre technologies, which offer finer filtration capabilities than microfibre and coarser materials, make nonwovens more competitive with alternatives such as membranes growth in manufacturing activities, which make use of nonwovens in both air and fluid filters.

Amongst the latest research in the sector is a recent development from Verdex Technologies, which has introduced a technology for spinning nanofibres using low-pressure air and no solvents. The technology provides nonwovens producers with the ability to offer a wide variety of functional enhancements to their products, particularly high-efficiency air filtration and liquid cartridge filtration products.

The growth in filtration applications will also be driven by continued regulation of air and water quality, requiring the filtration of outgoing air and wastewater in manufacturing applications; and increasing interest and awareness among consumers and homeowners in indoor air and drinking water quality, leading to new spending on filtration products.

While gains in key manufacturing sectors will support growth through 2024, the report also notes that gains will be limited in others due to the COVID-19 pandemic. For instance, motor vehicle production has fallen substantially in 2020 due to various stay-at-home orders across the US. However, demand for some end uses has increased, such as consumer water filters, with more consumer staying at home for longer periods. Additionally, sales of higher value filters that can provide better protection against airborne pathogens will help limit declines somewhat.

Over the long term, as smart technologies and reminders increase the replacement rate of disposable filters, particularly among consumers, sales of filters will benefit and, subsequently, demand for nonwovens used in those filters, the report says.
