Abstract:

This study aims at Scotched flax and flax roving, besides, the weight loss, strength and the degree of fiber splitting as a measure of the standard for different enzyme treatment process. In the conditions of the enzyme treatment: pH 4.0 , 0.1 mol/L Citric acid - sodium citrate buffer ,40 ℃, 180 r / min with shock treatment ,4h. The results suggested that the tenacity and fineness of fiber after using mixing enzymes is 663 Nm and 1.03 tex, which is higher than the traditional scouring process. In addition, scanning electron microscopy(SEM)and FTIR spectra was used to evaluate the removal of gummy materials on the fiber bundles. SEM showed that the surface of hemp fiber is more smoother by enzyme treatment; and the FTIR spectroscopic results suggested the gum decreased.
