摘要：
To solve the problems of high energy consumption, hydrolysis of reactive dyes, high salinity and high discharge of wastewater in the conventional pad-dry-pad-steam process of cotton fabrics, a low-moisture content baking and steaming color fixation process for cotton fabrics was proposed using a sealed device. The changes of the fabric surface temperature in the sealing device were investigated, and the effects of moisture content on fabric heating and dyeing performance were discussed for theoretical analysis of low-moisture content baking and steaming color fixation for cotton fabrics. To determine the optimal technique, the effects of cotton fabrics baking and steaming temperature and time, and concentrations of substitute alkali and Na2SO4 were explored. Compared with the pad-dry-pad-steam process, the K/S value of the fabric dyed by low-moisture content baking and steaming color fixation process demonstrated an improvement. However, the rubbing fastness of cotton fabrics by the two processes was similar. Incorporating the sealing device in the pad-dye process offers a new method for improving reactive dye properties of cotton fabrics. © 2021, Periodical Agency of Journal of Textile Research.
