Characterization of biobleaching of Cotton/Linen Fabrics

Abdelrehim A Ramadan


Environment protection is becoming a serious concern for textile industries. In recent years, there has been a tremendous growth in the use of enzymes in wet processing of textiles due to its ecofriendly images. Glucose enzyme suitable for textile applications, glucose oxidase enzyme is one of the most important. By blending linen (Hibiscus cannabinus L.) with cotton (Gossypium hirsutum L.), new high-end uses for kenaf have been identified. In this work the biobleaching of cotton, Linen and their blends with glucose oxidase enzyme (GOE) was optimized for enzyme concentration, D-glucose dosage, temperature, duration, and pH values and compared with conventional bleaching technique. The optimum conditions existed with 25 U/ml enzyme concentrations, 10 g/l D-glucose, 85oC-bleaching temperature, 90 minutes duration and pH value was 10. Biobleaching technique showed good results when compared to the conventional one with respect to the whiteness and yellowness indices, in addition a comparable mechanical behaviors to the conventional bleaching.
