Abstract

The disclosed preparation method for nano-polymer microemulsion in ink-jet printing comprises: using soft monomer butyl acrylate as main polymonomer for well film-forming flexible; adding comonomer with cross-linkging group to form three-dimensional space network structure and fix the color particle hard on textile fabric to prevent film tacky and endow the fabric with well resistance ability; adding polymerisable surfactant to let the polymer microemulsion have super stability even with much soft monomer and average size less than 100nm hard to agglomeration. This invention can obtain the product with small size and narrow distribution.

Description

technical field [0001] The invention relates to an adhesive for textile printing, in particular to a nanoscale polymer microemulsion for textile inkjet printing and a preparation method thereof. Background technique [0002] Inkjet printing technology is a brand-new textile printing technology. It sprays the ink containing pigment (dye or pigment) onto the substrate to be printed through the nozzle of the inkjet printing machine, and is controlled by the computer to form a pattern according to the design requirements. According to the performance of the ink, the printed fabric with certain fastness and vividness can be obtained through proper post-processing. Compared with traditional printing methods, inkjet printing has many advantages such as printing high-precision personalized patterns, meeting the production requirements of small batches and multiple varieties of textiles, quick response, saving time and space, and environmental protection. [0003] One of the core te...
