Textile Sci. ii. 75 With the introduction of nylon an entirely new method of fibre spinning was established—so-called melt-spinning in which the polymer..is melted in a novel device above the spinneret so that it can..be extruded through the multi-holed spinneret into cold air. 1974 Encycl. Brit. Macropædia VII. 258/2 In wet spinning, the solution of fibre-forming material is extruded into a coagulating bath that causes the jets to harden. 1974 Encycl. Brit. Macropædia VII. 258/2 In dry spinning the fibre-forming substance is dissolved in a solvent before the solution is extruded. As the jets of solution emerge from the spinneret, a stream of hot air causes the solvent to evaporate from the spinning solution, leaving solid filaments. 1974 Encycl. Brit. Macropædia VII. 258/2 In melt spinning the fibre-forming material is melted and extruded through spinnerets, and the jets harden into solid filaments as they cool on emerging from the spinneret. wet spinning wet spinning n. (a) spinning of natural fibres when they are wet from passage through a water bath; (b) spinning of man-made fibres in which the spinneret extrudes the streams of liquid into a coagulating bath.

This is known as ‘wet-spinning’. 1927 T. Woodhouse Artificial Silk: Manuf. & Uses 28 The coagulation by means of liquid of any kind has given rise to the term ‘wet spinning’, whereas the term ‘dry-spinning’ has been applied in all cases where the solvent is vaporized. 1969 A.
