棉织物泡沫染色工艺的筛选和优化

泡沫染色是一种低给液、高节能的染色技术，其成熟发展能改变传统染色方式高能耗，高污染的现状，顺应节能环保的时代潮流。本文利用上海誉辉化工有限公司生产的泡沫染色中试设备，通过Plackett-Burman实验，最陡爬坡实验和Central Composite Design(CCD)实验，以K/S值和皂洗牢度作为染色效果响应值，研究了汽蒸温度、汽蒸时间、稳定剂浓度、碱剂浓度、泡比、带液率六个因素对泡沫染色效果的影响。实验研究表明：汽蒸温度、泡沫稳定剂浓度、汽蒸时间为显著影响因素，当汽蒸温度为147.5℃，稳定剂浓度为0.92g/L，汽蒸时间为3.97min时，K/S达到最大，水洗色牢度达到4级。

Selecting and optimizing of parametersof foam dyeing process of cotton fabrics

As a new kind of low water consumption and energy-saving continuous dyeing process, foam dyeing caused an upsurge of research interest in the world. In this study, K/S value and soaping fastness as the response values were used to evaluate the foam dyeing effect. The influences of dye foam ratio, wet pickup, stabilizing agent concentration, alkaline agent concentration, steaming temperature and steaming time on the foam dyeing effects were studied by Plackett-Burman design, steepest ascent experiment and Central Composite design experiments. The results indicated that the steaming temperature, stabilizing agent concentration and steaming time were the most crucial factors that affect the foam dyeing effects. When their values were set as 0.92g/L, 149.5℃ and 3.97min respectively, K/S value got to the highest value and the washing fastness was up to 4 level.
