Calico, calico after the official enriching scattered calico provided by the official enriching. Calico, after the official enriching cloth, calico dispersed after officials enriching Changyi City, Shandong Province Textile Co., Ltd. (www.fumintex.com) 2014 upgrade been newly introduced method of controlling the permeability of the whole water-based pigment printing system will often Calico scattered infiltration phenomenon occurs, the impact of the pattern contour finish. To this end, should adopt semi-emulsion pigment printing system, while in the printing paste printing paste is added to prevent the infiltration of improved rheological additives, such as Printrite PM (American BF Goodrich Company), to improve the use of synthetic thickeners original paste printing paste flow properties, to prevent the infiltration of printing paste, reduce the permeability of printing paste. Currently, the dyeing emulsion paste is also chosen as a coating cloth printing paste thickeners, as in the emulsion paste mechanical shearing force, which is lower than the static viscosity, when the shear force is removed, but also approximation quickly restored to the original, and therefore, a smaller emulsion paste thixotropic conducive clear outline printed pattern. However, it is with high boiling white kerosene, water, emulsifier formed under high speed stirring, not only costly, but also release large amounts of kerosene fumes after printing drying or baking process, the smell is serious, not only pollute the environment and waste of energy, but also easily lead to fires. Developed less solvent or solvent-free thickener is necessary, China from the late 1970s have begun to develop the impermeability of the special paste, such as silk, Zhejiang Institute of Science have developed a special paste impermeability of decentralized printing polyester cloth, can effectively prevent the penetration of printing paste. It uses a non-ionic emulsifier outlet cloth, can quickly dispersed into droplets 1μm or less, and narrow particle size distribution of the fine particles uniformly and help agent added, texture modifiers and the like additives, and finally adding low solids amount of electrolyte-resistant synthetic glue, dubbed the impermeability of the special paste. Knitted fabrics in the rapid development of printing in just ten years, it is difficult to control because of its dimensional stability during processing, such fabrics, in particular rotary screen printing cotton knitted fabric containing spandex difficult to develop, which in addition to cotton knit fabric itself The size of plasticity, into the outer fabric drape itself into the fabric frame weight and tension, but also by the speed of change in tensile strength, shape and size of the flowers more difficult to control, geometric pattern encountered more difficult to maintain the original flower Some spirit difficult to achieve satisfactory results. This must take the necessary control over the entire process, in order to be resolved.
