The abilities of four chelators to separate bast fibers of non-retted oilseed flax from each other and the core and cuticle have been investigated at different pH level. EDTAand DTPA separate fibers efficiency at pH 10. Addition of a strong detergent (Sodium dodecyl sulphate, SDS) or sodium chloride further increased the fiber separation and so delignifying compounds hydrogen peroxide and sodium sulfite. A mixture of EDTA, SDS and hydrogen peroxide gave a complete fiber separation within 2 h at 70 degrees and pH 10. The fibers in the woody core of the flax straw did not separate under these conditions. The mechanistic background to fiber separation is discussed.
