Nonwoven chitosan - preparation and properties

This article focuses on preliminary investigations of the manufacture of nonwoven chitosan from a 38-mm chitosan staple fibre and fibres containing silver nanoparticles. The nonwoven chitosan is built of several needle-punched layers of fleece, with a lengthwise arrangement of chitosan fibres. Estimated were mechanical and sorption properties, apparent density, thickness and air permeability of the nonwoven chitosan.
