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.

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. < as lemmas |
