Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a high-efficiency and rapid steaming printing process of reactive dyes. Background technique [0002] Direct printing is one of the printing methods, which is named after printing the printing paste directly onto the fabric. This printing process is the simplest and most common of several printing methods. According to different pattern requirements, it is divided into three types: white ground, full ground and colored ground: the area of ​​white ground printing is small, and the area of ​​white ground is large; the area of ​​full ground printing is large, and most of the fabric is printed with patterns; the direct printing of color ground It means that the ground color is dyed first, and then the pattern is printed, which is commonly called "overprint". However, due to the overlapping colors, the same color is generally used, and most of the similar colors or light...
