Research on Enzyme Boiling Out and Bleaching Technology Based on Flax Roving.

We adopt pectin compound enzyme to boil out flax roving. Use catalase to remove the residual oxydol left after bleaching with oxydol. Then adopt orthogonal table in mathematical statistics and variance analysis. States the affects brought by enzyme concentration, ph, temperature, time etc to boiling out and bleaching. The optimal technical parameter and technical route of enzyme boiling and bleaching are confirmed. The sought optimal technique: concentration of oxydol is 8 g/L, pH value is 9, temperature is 65?, duration is 50min, mixing speed is slow, and concentration of compound enzyme is 0.006g/L. 3. Catalase is used for removing the residual oxydol in flax roving after the bleaching with oxydol. Through variance analysis, the biggest influential factor is duration, and the next is the concentration of catalase, temperature, and pH value. The sought optimal technique: concentration of catalase is 0.06g/L, pH value is 7, duration is 20min, and temperature is 50?. Inspection analysis shows that boiling & bleaching liquid is of no pollution, which can realize clean production. [ABSTRACT FROM AUTHOR]
