difference between dry and wet spinning
Dry spinning: Dry spinning is used for polymers that need to be dissolved in a solvent. Solvent spinning (dry spinning and wet spinning) are used by 30% of the fibers. Spinning process: â¶ In dry spinning, a volatile solvent is used to dissolve the raw materials and form a salutation. â· Then the solution is purified by filter.
In the bast and leaf-fiber 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. Open-end Spinning;
Wet spinning is required for polymers that require dissolving in a solvent to be spun. It is named wet spinning because the fibres are extruded directly into a liquid bath.
