Abstract

Nearly all the textile synthetic fibres now available are industrially produced by bringing a spinnable material into liquid state, molten or concentrated solution, and forcing it through a small die to form a free liquid jet at the exit. This solidifies as it proceeds along the spinning path and the solid fibre is collected on a rotating drum. Solidification is due to cooling in the melt spinning, to evaporation of solvent in the dry spinning or to precipitation of polymer from solution in wet-spinning.
