CAMBRIDGE – Supramolecular chemistry company Aqdot will introduce its new AqFresh technology at the forthcoming Techtextil in Frankfurt from June 21-24.

AqFresh, which is supplied as a powder, has been proven to capture urine and sweat malodours when dry impregnated into nonwoven-based absorbent hygiene products (AHPs), as well as air filter media and other products, and is based on cucurbiturils – barrel-shaped molecules with hollow hydrophobic cavities and polar portals.

These enable the technology to capture and hold the malodours with extremely tight binding so they are virtually undetectable to the typical consumer.

AqFresh works in wet environments where AHPs are typically used, and does not rely on sensitising or allergenic fragrances or on antibacterials to which bacteria are becoming increasingly resistant.

Current odour-counteracting technologies are relatively ineffective and rely on fragrances to mask the odour.

AqFresh is a versatile odour and pollutant capture technology with the potential to be incorporated into nonwovens produced using a variety of methods, whether needlepunched, spunbonded, airlaid or meltblown, based on polypropylene, polyester and many other fibres.

UK-based Aqdot is at stand B80 in Hall 11 at Techtextil 2022.
