Flax fibre, pre-treated in a 2-step process with a chelating agent for calcium followed by a commercial pectinolytic enzyme preparation, was modified with either PVA (poly(vinyl acetate)) or PEG (poly(ethylene glycol)). After treatment the fibres were found to have undergone surface and bulk chemical changes, identified through near infra-red spectroscopy (NIR) and differential thermo gravimetry (DTG)...
The use of enzymes, chelators and enzyme/chelator systems was explored as an environmentally friendly means of improving the quality of flax fibre for composite applications. A commercial pectinolytic enzyme preparation and Ethylene Diamine Tetraacetic Acid (EDTA) were used separately and in combination on a commercial flax fibre. An improvement in fibre cleanliness and separation of the fibre bundles...
