摘要：

以亚麻打成麻及其粗纱为研究对象，以质量损失率、强度和细度（分裂度）作为评定标准，对生物酶处理工艺进行了研究。结果表明：在pH为4的柠檬酸-柠檬酸钠缓冲液中，温度40 ℃，180 r/min震荡处理4 h下，果胶酶、木聚糖酶和甘露聚糖混合处理后的原麻和粗纱分裂度和强度最优，分裂度663 Nm和1.03 tex,强度分别17.07 cN/tex和34.02 cN/tex，纤维强度均比化学方法处理后的高。采用扫描电镜、红外光谱对纤维上胶质的去除情况进行了分析，结果显示：酶处理后的麻纤维表面更加光滑，胶质含量下降。

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.

Key words: flax, prctinase, gemicellulase, scetched flax, flax roving
