Focus Nonwovens a specialist arm of Courtaulds Research supports Courtaulds Fibres Ltd in the development of new nonwoven products. Courtaulds sees hydroentanglement as an important development in the nonwovens sector, and Focus Nonwovens is extending its hydroentanglement facilities. It has ordered a high-pressure pilot line from the French company Perfojet which is capable of bonding a wide variety of webs. Courtaulds' Viscose staple entangles well, as does the solvent-spun cellulosic fibre Tencel. Under high water pressure Tencel has been shown to split into microfibres which it is considered may offer some benefits.
