The printing of knit fabrics for advertising shirts has developed rapidly in just ten years, but due to the difficulty of controlling its inch stability in the processing process, it is difficult to develop knitwear, especially rotary screen printing containing spandex knitted fabrics, except for the cotton knitted fabric itself. The size and plasticity of the pattern are large. In addition to the drape weight and the tension of the cloth feeding frame when the cloth is inserted, it is also affected by the stretching force of the speed change. Some spirits can hardly achieve satisfactory results. This must be solved by taking necessary control over the entire processing process. Printing process of Poly Spandex fabric. Weaving open-width rolling + loose cloth + (6 steaming)-pre-shaped one + pre-treatment-+ (dying) → printing-+ steaming-→ washing> dehydration> drying → shaping. The processing method of color separation design draft. Computer color separation drafts must first be based on the type of fabric, the size of the elasticity, the number of sets, the number of sets, the printing method (direct printing, pull printing, anti-printing), deep and light levels of multicolor, and the scale of the draft to meet the production requirements specification. Scale of printing size. Under the conditions allowed by the return. Generally, when the spandex content in cotton spandex is between 3% and 5%, the condition design of the entire printing process must be considered. Various parameters of rotary screen printing have been formulated while drafting. The printing speed of the above data is controlled between 30 and 40m/min. If the printing speed is above 50m/min, the warp elongation ratio of the flower shape is required to be greater, but the general printing speed is below 40rn/min, regardless of the flower shape Still the quality is easier to control.
