3 important questions on Structuring of biopolymer products - Processing of dense biopolymer systems - Spinning
How are fibres formed with wet spinning?
Fibres are formed when the protein dispersion, often soy, is forced through a spinneret with many small holes into an acidic bath.
How are fibres formed with dry spinning?
Very thin protein fibres are formed. The protein solution can be solidified after elongation through solvent evaporation or by cross-linking the proteins.
Why is spinning not used industrially?
- High costs
- Large waste streams (water)
- High protein loss
