Fabric Definition:
Kapok is a soft, fluffy, and highly buoyant seed fiber harvested from the pods of the Kapok tree (Ceiba pentandra), prized for its hollow structure, exceptional lightness, and natural water-repellent properties.
Composition:
100% Cellulose (Plant Fiber) – unique hollow, tubular structure with a smooth, waxy surface (lignin and cellulose)
Texture:
Exceptionally soft, fluffy, silky, airy, with a smooth, slippery hand; not as compressible as cotton but very lightweight
Stretch Level:
None (No stretch; extremely fragile and brittle when dry)
Fabric Construction:
Nonwoven (Battings, Felts, Paddings) or Blended with cotton for spinning (though difficult to spin alone)
GSM Range:
100-300 GSM (Light for insulation, medium for fill layers, heavy for nonwoven pads)
Breathability:
Excellent – Highly breathable; the hollow tubes allow airflow
Moisture Management:
while trapping air for insulation
Durability:
Low (Hydrophobic – does not absorb water well, but absorbs oils and retains buoyancy)
Thermal Properties:
Low (Fibers are fragile, brittle, and short; not suitable for high-wear applications; blends needed for durability)
Key Usage Areas:
Washing, Bleaching (rarely), Anti-static treatments, Fire-retardant coatings, Water-repellent finishing (natural)
Insulated Outerwear, Sleeping Bags, Pillows, Cushions, Mattress Toppers, Pet Beds, Acoustic Wall Panels, Flotation Devices
