IMMATURE FIBRES IN THE YARN , DEAD COTTON IN THE YARN
Immature fibres in the yarn:
If the yarn has many immature fibres in it, then these immature fibres appear in the form of small balls on the fabric surface.
These immature fibres have very poor dyeing affinity and do not pick up the colour in dyeing. These immature fibres can be dissolved in the mercerisation process up to the maximum extent. These immature fibres become a much serious issue when yarn dyed fabric is woven. The immature fibres can be removed during dyeing package preparation by adopting close setting of slub catcher blades up to some extent. These fibres appear in the form of undyed fibres on the fabric surface. These fibres can be removed by bio polish (enzyme wash) up to some extent. Please note, there is always a chance of change in the shade during this process.
