Kapok fibre spinning process

A process for obtaining a spinnable and/or needable Kapok fibre fraction, and/or Kapok fibre blend with one or more other fibres in a range of from 100% to 5% by weight, the process comprising the steps of:

• a. sorting the longest and cleanest kapok fibres for spinning, which comprises volatizing opened and unsorted Kapok fibres by subjecting them to an air stream, whereby the fibre-containing air stream is directed towards a deposition area comprising a sorting wall, whereby fibres of different lengths are deposited in the deposition area and/or against the sorting wall at a position commensurate with their length, weight and the resulting respective flight time, whereby a longer fibre fraction is collected behind the sorting wall, to obtain a short staple Kapok fibre base having an average length of at least 10 mm;
• and
• b. adjusting the average moisture content of the kapok fibre base to an average measured moisture content in the range of from 8% to 12% moisture, to obtain moisture- and length-adjusted Kapok fibres.
