One-Step Dyeing of Polyurethane Fibers

The effect of bulk density on the tensile strength and air permeability of a nonwoven needle-punched fabric based on polyester fibers with a linear density of 1.7 tex is investigated. The bulk density of the fabric was varied by processing in the clearance between a heated roller and a conveyor belt. A twofold increase in tensile strength was achieved with a relatively small decrease in air permeability.
