Abstract:
The present invention relates to a process for obtaining a spinnable and/or needlable Kapok fibre fraction, and/or Kapok fibre blend with one or more other fibres in a range of from 100% to 10% by weight, comprising the steps of: •a. sorting the longest and cleanest fibres for spinning, by subjecting the fibres to an air stream directed towards a deposition area with a sorting wall, whereby a longer fibre fraction is collected behind the sorting wall, to obtain a short staple Kapok fibre base having an average length of from 10 to 20 mm; •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, and, optionally •c. blending the moisture-and length-adjusted Kapok fibres with the second fibre base, to obtain a Kapok-comprising fibre blend.
