Selecting and optimizing of parameters of foam dyeing process of cotton fabrics

The goal of this study was to explore the optimal foam dyeing proces. It adopted PlackettBurman design,the steepest ascent experiment and central composite design( CCD) to investigate the impact of steaming temperature and time,stabilizer concentration,alkaline agent concentration,foam ratio,and wet pick-up ratio on the result of foam dyeing,using K / S values and soaping fastness as the response values. The results indicated that the steaming temperature, stabilizer concentration and steaming time were the significant factors that affected the foam dyeing effects. And when their values were set as 0. 92 g / L,147. 5 ℃ and 3. 97 min,respectively,K / S value reached the highest one and the washing fastness was up to rating 4.
