정련은 면에 있는 지방을 제거하는 과정으로 면섬유의 흡수성을 증가시키는데 그 처리 목적이 있는데, 현재 산업체에서는 그 뛰어난 효과 때문에 알칼리를 이용하여 고온에서 면섬유를 처리하고 있는 실정이다. 강한 알칼리 용액은 면섬유의 일차세포막을 공격하여 비셀룰로오즈 성분을 제거하게 되는데 이때 옥시셀룰로오즈의 형성에 의해 면섬유를 손상시키게 된다. 환경적인 측면에서도 알칼리 정련은 높은 BOD, COD, TDS을 유발하는 문제점을 갖고있다. (중략)

The effects of removal of lignin or hemicellulose on the cottonizing and pulping characteristics of kenaf fiber were studied by comparing the conditions of non-cellulosic material contents, fiber lengths and dyeability. And the effects of lignin or hemicellulose on dyeability of the kenaf fiber using CI Direct Green 26 and CI Direct Red 81 were investigated. The results were as follows. The lignin contents decreased and the kenaf fiber became shorter and finer as the reaction time with sodium chlorite increased. The hemicellulose could be removed by treating sodium hydroxide solution to the fiber from which the lignin partly removed. The 80% of hemicellulose could be removed by 5% of sodium hydroxide solution in 5 minutes. But if lignin were not removed at all, hemicellulose could not be removed. The fiber lengths proper for apparel were obtained after treating sodium chlorite for 10-20 minutes and those for pulping were obtained after treating sodium chlorite for 40 minutes. The kenaf fibers from which lignin and hemicellulose partly removed were dyed with CI Direct Green 26 and CI Direct Red 81. Their dyeability increased as the removal rates of lignin increased. The ${\Delta}E$ values of kenaf fiber dyed with CI Direct Green 26 were lower than CI Direct Red 81.
