摘要
针对纤维素纤维与锦纶纤维混纺针织物传统两浴两步法染色耗时长、耗能大、污染严重等问题,文中选用新型活性染料对其进行一浴一步法染色。介绍了纤维素纤维与锦纶纤维混纺针织物的前处理、染色及后整理工艺,并将一浴一步法染色与传统两浴两步法对比,测试了织物的色差、耐皂洗色牢度、耐水色牢度、耐摩擦色牢度、能耗及生产成本。结果表明,一浴一步法染色后织物的耐皂洗色牢度、耐摩擦色牢度、耐水色牢度与传统两浴两步法工艺相当,且色差值较小,符合行业优等品标准要求;一浴一步法染色生产效率高,处理1 t黏胶与锦纶混纺针织物节省用水50 t,节能250 k W·h,节汽0.8 m3,节约成本526元,具有节能减排的作用。
In view of large time-consuming, energy-consuming and pollution-intensive problems of the traditional two-bath and two-step dyeing of blended knitted fabrics of cellulosic and polyamide fiber, this paper adapted a new one-step and one-step dyeing process using a new type of reactive dye. It introduced the pretreatment, dyeing and finishing process of blended knitted fabrics of cellulose and polyamide fiber, and competed one-step and one-step dyeing process with the traditional two-bath and two-step method, and tested the dyed fabric properties, such as color difference, color fastness to soaping, color fastness to water, color fastness to rubbing, energy consumption and production cost. The results show that the color fastness to soaping, color fastness to rubbing, and color fastness to water of the fabric after dyeing with one-bath and one-step were equivalent to the traditional two-bath and two- step method, and the color difference was small, which can meet the industry＇s superior product standards. One-bath and one-step dyeing process has high production efficiency, which can save 50 tons of water, 250 kW-h of electric energy, and 0.8 m^3 of steam, and save 526 yuan in cost by dealing with one ton of blended knitted fabric, which has the effect of energy saving and emission reduction.
