Constant add-on via wet-on-wet padding

Research output: Contribution to specialist publicationArticle


One common problem associated with wet-on-wet or prewet processing is that after padding several hundred yards of yarn/fabric, chemical add-on is considerably decreased, resulting in poor performance of the finished goods or decreased shade depth. This decrease is due to neglecting the impact of water being transferred from the prewet pad to the chemical pad in the process. This work investigated the water interchange in the chemical pad and developed a reconstitution method. The consistent shade depth and add-on developed in wet-on-wet pad/batch dyeing and wet-on-wet resin finishing indicated that the method could also be recommended for wet-on-wet padding processes.
