Abstract

The invention discloses a preparation method of an inorganic-organic composite inkjet printing paste. In the method, specially modified bentonite is adopted as a printing stock paste to completely or partially replace an organic stock paste in a traditional inkjet printing paste to prepare an environment-friendly inkjet printing paste. Compared with traditional organic inkjet printing pastes including sodium alginate and the like, printing wastewater generated by adopting the paste provided by the invention is greatly reduced in pollution degree because an organic paste is replaced by inorganic substances; and moreover, compared with an inorganic-organic composite paste of non-modified bentonite, a printed fabric produced by adopting the paste provided by the invention is higher in color yield and better in line sharpness. Therefore, the inorganic-organic composite inkjet printing paste is a low-pollution environment-friendly composite printing paste. The inorganic-organic composite inkjet printing paste disclosed by the invention not only is suitable for inkjet printing of natural fiber fabrics of silk, cotton, flax and the like, but also can be applied to flat and rotary screen printing of the natural fiber fabrics.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, and in particular relates to a preparation method of an inorganic-organic composite ink-jet printing paste. Background technique [0002] Digital printing is currently the highest-grade printing product recognized internationally. Compared with traditional printing, digital printing has four advantages: (1) Digital printing saves the process of making flower nets and patterns in traditional printing methods, which greatly speeds up the printing and proofing speed, and reduces the proofing cost. (2) Digital printing is not limited by the size of the flower circumference and color registration of the pattern. It has accurate flower alignment, rich layers, and good printing effects. It can be used for printing high-end textiles. (3) Digital printing production realizes small batches and quick response to customer needs, and can produce high-grade and personalized printing products. (4) D...
