Abstract

Trademark fabric was prepared with the water polyacrylate as a coating agent and a compound of kaolin and CaCO₃ as filler to study the fabric’s digital inkjet printing performance. Results showed that a 7:5 ratio of kaolin and CaCO₃ in the fabric produced uneven pores; the best ink absorption, quick-drying performance and the best printing sharpness and the highest colourfastness to crocking. The coating slurry included 100 g water, 25 g EC-507 modified styrene acrylic emulsion, 75 g compound filler (kaolin and CaCO₃ according to mass ratio 7:5), 1.5 g dispersant and 0.375 g crosslinking agent. The optimised coating process was a baking temperature of 150 °C and a baking time of 90 s. The fabric was printed upon using an Epson label printer, producing a printing pattern with good printing sharpness (e.g. lines had no bleeding phenomenon, text and patterns were clear, colours were better and printed two-dimensional codes were scannable).

摘要

以水性聚丙烯酸酯为涂层剂，以高岭土和CaCO ₃的化合物为填料制备商标织物，研究织物的数码喷墨打印性能。结果表明，织物中高岭土和CaCO ₃的比例为7:5时，会产生不均匀的孔隙；最佳的吸墨性、快干性能和最佳的印刷清晰度和最高的耐摩擦色牢度。涂料浆料包括100克水、25克EC-507改性苯丙乳液、75克复合填料（高岭土和CaCO ₃按质量比7:5)，分散剂1.5克，交联剂0.375克。优化后的涂层工艺为烘烤温度为 150 ℃，烘烤时间为 90 秒。织物采用爱普生标签打印机进行打印，打印出的打印图案具有良好的打印清晰度（如线条无渗色现象，文字和图案清晰，色彩较好，打印的二维码可扫描）。
