  3. 3. OBJECTIVES To identify the potential natural fibers (Kapok). To study the suitable method on processing the Kapok fibers. To do fiber identification test to determine the Kapok fiber properties. To identify the end-use of the Kapok fiber.
  4. 4. INTRODUCTION Kapok tree does not grow wild in Malaysia and it comes from the tropical America's. Kapok fibres on their own are not suitable for spinning into yarn. (as they are too smooth, slippery and brittle) Kapok fiber's essential attributes are many: buoyant, resilient, moisture resistant, vermin resistant and smooth, kapok possess powerful performance in a lightweight package. When kapok fibers are put under tension they completely return to their original length when the tension is removed. The conventional end uses of kapok include mattress/pillow
  5. 5. Microscopic view of cross-section of Kapok
  6. 6. Kapok sheds its leaves in the dry season, revealing hundreds of 15 cm long leathery pods and small flowers that are pollinated by bats. When mature, the pods burst open revealing a whitish fibre surrounding round brown seeds which are dispersed by the wind. The seeds can be oils Kapok trees bring a lot of significant to human, as their wood are lightweight and porous which are very suitable for making carvings, coffins and canoes. The silky fibres are suitable for making stuffing and life jacket. Oil in the seeds can be made as soap and other parts of the tree are used as medicines to treat fever, asthma, kidney disease and dysentery.
  7. 7. METHOD OF PROCESSING KAPOK
  8. 8. Kapok harvesting process requires a lot of manpower, as each step is done mostly by hand. The process starts with: Harversting The ripe unopened pods are normally harvested by knocking them off the tree, but they can also be cut from the tree or harvested when they fall to the ground.
  9. 9. Sorting dry cottonwood logs Sorting kapok weather it is wet or dry. If wet kapok will be dry under the sun rays until it really dried.
  10. 10. Then it was dried in the middle of the scorching heat to dry skin. The best time for processing the kapok is early in the morning when the weather and the air were still moist and not dry. If done in the afternoon, kapok fibers become flying.
  11. 11. removing Kapok hulls the fruits are hulled and seed and fibres were removed from the pods by hand. This process is done by using hand
  12. 12. DRYING Kapok fibre is dried under the sun for 3 to 5 hours for complete drying.
  13. 13. Seed removing The seeds lie loose in the floss and, with the help of some beating they fall to the bottom of the container where they are easily separated. In this process, kapok pith removed.
  14. 14. Packing The seed-cotton was inserted into the container barrel. Then a device called a bow inserted in the container bins and scrub process is done.

  16. 16. NO. TITLE EXPLANATION 1. Fiber length  About 2.5 cm long  All natural fibers are staple fiber 2. Burn test Plant based fibers that are suitable for dyeing with fiber reactive dyes will • Ignites and burns quickly, may flare, leaves a glowing ember after flame is extinguished. • Smoke is white or light colored and • Smells like burnt paper or leaves. • Ash is light gray or white and very soft.  Highly inflammable.  Burns with light grey smoke when in flame.  Then burn with ember after flame is extinguished.  Ignites and burn quickly.  Leave whitish ash residues. 3. Surface contour • Smooth surface contour when touch. 4. Color • White or pale yellow in color 5. Care • Natural biodegradable fibres

  19. 19. • Clothing. The natural wax coating of the fibre only allows a low level of moisture absorption – an advantage that promises excellent wearing properties for clothing textiles.
  20. 20. Conclusion The conventional end uses of kapok include mattress/pillow stuffing, upholstery and thermal insulation. The market for kapok in these traditional uses has declined considerably over the past 30 years, due to the developments in synthetic materials, such as foamed plastics, which have almost replaced kapok in most of its traditional end uses. Attempts to use kapok fibre for producing textile yarn were not successful due to the slippery nature of the fibres and its brittleness. The fibre yarn resulting from blending kapok with cotton is potentially suitable for producing woven textile fabrics. In addition to its potential use as clothing material, the fabric is being considered for suitability as reinforcement to thermosetting polymeric materials such as polyester and phenolic resins
