Over recent years the Aquafil division of the Italian-based Bonazzi group has been best known as a producer of polyamide and polyamide microfibres. However a policy change officially confirmed at the beginning of this year now puts the group firmly back into the polypropylene marketplace too. The decision rests on the launch of an innovative polyprop microfibre which will be marketed under the brand name Dryarn and which is particularly likely to appeal to producers of performance fabrics destined for use in work or sports wear, although Aquafil executives suggest that it could also have important applications for the lingerie and underwear trade.
