Based on the wide selection of domestic and foreign coating binders, thickeners and their adjuvants, this project has developed and developed adhesives suitable for the printing of silk and silk multi-fiber interwoven or blended lightweight fabric coatings. Softeners and wet rubbing fastness improvers for thickeners, crosslinkers and coatings. In-depth study of the relationship between the performance of the discharge agent and the performance of the color coating, focusing on the new high-efficiency no/low formaldehyde discharge agent and stable silk dye printing and printing super soft special composite pulp, high-resistance color coating, Developed a direct printing technology for high-grade silk and silk multi-fiber lightweight fabrics and environmentally-friendly high-color fastness paint printing technology. The production of silk and silk-containing multi-fiber paint printing fabrics that are close to or reach the level of fuel printing and dyeing, realizes the processing of light and thin fabrics such as water-free silk. The developed waterless paint printing technology has reached the international leading level, and the auxiliary additives have reached the international advanced level of similar products.
Technical indicators that can be achieved in this project: product color fastness: washable ≥4～5 grade, sweat resistance ≥4～5 grade, dry friction ≥4 grade, moisture resistance ≥5 grade, lightfastness 5 grade; feel close to or reach Dye printing and dyeing level; direct printing formaldehyde detection <20mg/kg, carved formaldehyde detection amount 58.9mg/kg; no detectable dye, extractable chromium content (<1.0mg/kg), water extract The ecological indicators such as pH value (7.1) meet the requirements of international textile environmental protection standards; the APEO detection amount is 0mg/kg; the deepening effect is ≥20% (based on polyester-cotton as the standard fabric); the water consumption per unit of output is 30% lower than conventional printing and dyeing. , energy saving 35%. The results of this project have been maturely applied to large-scale production, with significant economic and social benefits, and broad application prospects. (Zhejiang University of Technology)
