摘要
采用酸性纤维素酶、酸性果胶酶和木聚糖酶复配对亚麻粗纱纤维进行煮练,通过正交试验确定酶处理的最佳工艺条件为酸性纤维素酶用量7.5%(omf),酸性果胶酶用量1.0%(omf),木聚糖酶用量2.0%(omf),反应时间70 min,反应温度40℃,p H=5.0,氯化钙用量0.5%(omf).对生物酶煮练和未处理的亚麻纤维进行红外光谱、X-射线衍射和扫描电镜表征,结果表明:生物酶处理后的亚麻纤维表面光滑无麻点,结晶度下降,无定形区增加,对果胶、木质素等杂质有一定程度的去除.
Acidic cellulase, acidic pectinase and xylanase were compounded and applied in scouring of linen roving. The optimum technology conditions of enzymes scouring were determined by orthogonal test： acidic cellulase usage 7.5%（omf）, acidic pectinase usage 1.0%（omf）, xylanase usage 2.0%（omf）, treated at 40 ℃for 70 min under pH=5.0, and calcium chloride usage was 0.5%（omf）. Flax fibers treated with enzyme and control flax fibers were characterized by X-ray diffraction, infrared spectroscopy and scanning electron microscopy. The results showed that the surface of the fibers after enzymatic treatment was smooth without pitting,the crytalinity decreased, the amorphous region increased, part of pectin, lignin and other impurities were removed.
