  • the mass percentage of the kapok fibres 14 in the mixture of fibres 14, 16 constituting the non-woven body 12 may be between 10% by mass and 30% by mass, advantageously between 10% by mass and 20% by mass, advantageously between 10% by mass and 19% by mass.
  • the mass proportion of cellulose fibres other than kapok 16 in the mixture of kapok fibres 14 and cellulose fibres 16 other than kapok of the non-woven body 12 is between 90% by mass and 70% by mass, advantageously between 90% by mass and 80% by mass, advantageously between 90% by mass and 81 % by mass, the total of the mass percentage of the fibres 14 and the mass percentage of the fibres 16 being 100%.
  • Such a content of kapok fibres allows a very soft feel to be obtained, with production of the non-woven bodies being kept simple, even if the kapok fibres are of small size.
  • the softness is further obtained in a surprising manner even with a small quantity of kapok fibres, which allows the production cost of the non-woven bodies to be reduced.
