Process for converting tropical plant material into fibers
First Claim
1. A process for converting a tropical plant material into naturally hydrophobic fibers, said process comprising the steps of:
- providing a naturally hydrophobic fibrous tropical plant material having an initial latex content, said fibrous tropical plant material selected from the group consisting of;
banana stalks, plantain stalks, Cavendish plant stalks and pineapple crowns;
reducing said fibrous tropical plant material to a form a plurality of separated fibers having a initial latex content;
washing said plurality of separated fibers in an aqueous solution to extract a first portion of latex and other hydrophobic natural juices therefrom;
pressing said plurality of washed separated fibers to remove a second portion of latex and other hydrophobic natural juices therefrom, wherein said pressed fibers retain sufficient latex and other hydrophobic natural juices to remain hydrophobic;
drying said plurality of pressed separated fibers; and
wherein said dried seperated fibers have a latex content less than 50% of said initial latex content of said fibers prior to washing.

Abstract
A process for converting tropical materials into fibers useful in paper-making, textiles, insulation, general fiber filler and the absorption of liquids. The tropical materials utilized in the process include, banana, plantain or cavendish plant stalks, pineapple crowns, coconut, palm or palmetto fronds, or the pinzote of palm. The process includes the steps of: reducing the raw fibrous plant materials to separated fibers by cutting, shredding or grinding; washing the separated fibers in a mild alum solution to extract latex and natural resinous substances; pressing the fibers to remove a high percentage of excess water and residual latex and natural resinous substances with the consumption of a minimum amount of energy; and drying the fibers to less than 10% by weight water content.
