The present participle of the verb ‘to spin’ used verbally, adjectivally, or as a noun, meaning process or the processes used in the production of yarns or filaments.
Note 1: The term may apply to:
(i) the drafting and, where appropriate, the insertion of twist in natural or staple man-made fibres to form a yarn;
(ii) the extrusion of filaments by spiders or silkworms; or
(iii) the production of filaments from glass, metals, fibre-forming polymers or ceramics.
Note 2: In the spinning of man-made filaments, fibre-forming substances in the plastic or molten state, or in solution, are forced through the holes of a spinneret or die at a controlled rate. There are five general methods of spinning man-made filaments, but combinations of these methods may be used (see dispersion spinning, dry spinning, melt spinning, reaction spinning, and wet spinning)
Note3: In the bast and leaf-fibre industries, the terms ‘wet spinning‘ and ‘dry spinning‘ refer to the spinning of fibres into yarns in the wet state and in the dry state respectively.
