Method for preparing stain release jacquard fabric

The invention provides a method for preparing a stain release jacquard fabric. The method is characterized by comprising the steps that firstly, finishing liquid is prepared, wherein modified SiO2 hydrosol, hydrophilic components and water are taken to be mixed according to the weight ratio of (3-5):(1-3):(92-96), stirring is carried out, and the finishing liquid is obtained; secondly, a jacquard fabric is finished in the finishing liquid and dried, then the jacquard fabric is baked for 1-3 min at the temperature of 150 DEG C to 170 DEG C, and the treated stain release jacquard fabric is obtained. The stain release finishing agent of the stain release jacquard fabric is prepared from fluoride-free superhydrophobic ingredients of the modified nanosilicon dioxide hydrosol, the hydrophilic components containing acrylic acid and water, and has good stability, excellent water repellency and good low-temperature film forming performance, the hardness of a film can be adjusted by changing the composition of a copolymer, and good adhesivity on fibers is achieved. The soil release finishing agent is applied to the jacquard fabric, a padding finishing process is adopted, the method is simple, the application range is wide, high operability is achieved, and the need for developing the high-grade jacquard fabric can be met conveniently.
