Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2023 / V.35,no.4,Dec Title Printing Performance Evaluation of Water-dispersed Pigment Ink according to Additive Conditions of Film Substrate Surface Coating Agent Authors Hyeok-Jin Kim, Hye-Ji Seo, Eun-Ha Kang, Min-Woo Han1, Dong-Hyeon Lee2, Dong-Jun Kwon2, and Jin-Pyo Hong Institution/Affiliations 1DYETEC, 2Gyeongsang National University Pages/Total page pp.196 ~ 205 / 10 Language Korean Abstract Water-dispersed pigment is on-going study for without air pollution in the textile and print industry. Primer treatment is essential for the substrate to improve the printing quality of eco-friendly water-dispersed pigment ink. Otherwise in the case of untreated primer, the water-dispersed pigment ink will dry onto the surface and cause defective images. This study was conducted on film substrate coating (primer) to fix eco-friendly water-dispersed pigment ink on film substrate. The drying, bleeding, and color strength of the pigment ink were examined depending on the composition and mixing ratio of the coating solution. The mixing ratio of silica gel in the coating film is increased to 0, 0.5, 1, 2 and 3 and results that DK-1-3 of silica gel ratio of 1 showed the lowest bleeding such as 52%, the letter thickness of 0.76mm and DK-1-5 of SG ratio of 3 showed the highest bleeding such as 304%, the letter thickness of 2.02mm. The mixing ratio of SPA in the coating film is increased to 2.5, 5, 7.5, SPA ratio of 7.5 has a bleeding ratio of 9% and letter thickness of 0.544mm. It showed the closest value to 0.5mm. According to the result, the optimal mixing ratio of binder, polymer coagulant, silica gel is 100:7.5:1.
