Eco-PALF

on Tuesday, January 4, 2011
We had a finale presentation last Tuesday. Our group presentation was about ECO-PALF!!
'eco-friendly pineapple leaf fibre'. Other groups also presented their own unique products.

Some information on ECO-PALF:



Constituents of ECO-PALF:

            α-cellulose
74.44%
            Hemicellulose
13.39%
            Lignin
7.12%
            Pectic matter
2.89%
            Aqueous extract
0.58%


Natural fibre which environmentally friendly:
        Biodegradable
       Recycling agricultural waste
       Reduce the emission of CO2
       Cheap alternative and compatible to already existing synthetic fiber
       Natural-based product- not harm to human
       Low cost (abundantly available), low density (higher specific strength and stiffness) and low energy type of fibre (low carbon released).
       Can be easily process for industrial purposes without any additional cost (raw material is highly abundant).
       Make use of the undesirable part of pineapple (leaf)à good waste management practice.
       The composites containing long fibre PALF were stronger than the short fibre composites.
       The unidirectional arrangement of the long fibers à good interfacial bonding between the PALF and polymer.
       Reduction in crystallinity of the composites àreinforcing effect of PALF enhancing mechanical strength.
       The strength of the composites was found to be higher by 5.1%.
       Eco-PALF + silk or polyester = textile fabric.
       End fabric is lightweight, easy to care and has an elegant appearance similar to linen.
       More delicate in texture than any other vegetal fibre.
       The non-structural composites are suitable to use for low cost housing, civil structures such as doors, windows, furniture, etc.
