Nonwovens from the dust fractions of mechanically opened fibres

The aim of the demo was to utilise fine fibre fraction from mechanical opening process in nonwovens.

Two fine fibre fractions from LSJH`s mechanical opening line, cellulosic mix and synthetic mix, were processed with air laying and foam forming into nonwoven webs. The webs were bonded either by adding bi-co fibres and pulp into the webs.

Both short fibre fractions were suitable in air- and foam laying processes.
