In Depth Assessment on Digital Textile Printing Environment as the Concrete Path of Making Indonesia 4.0

Textile-garment industry in Indonesia has been established as the primary industry and economy that becoming fundamental to nation’s wealth. Well known as a top 5 of global market supplier, this industry predicted to keep score and improving their productivity to reach better position. In last 2019, Government of Indonesia already announced the roadmap plan of Indonesia 4.0, which put textile-garment industry as the one of priority industry that will be essentially adopting digital equipment and workflow to keep competitive and becoming the backbone of national industry alongside with other 4 industries mentioned. With this initiative being deployed and how the road map plan already announced, Author want to elaborate, assess and analyse how ready is digital adoption on textile-garment manufacturers, specifically on digital printing workflow. So on, this research will be titled “In Depth Assessment on Digital Textile Printing Environment as the Concrete Path of Making Indonesia 4.0”. The main purpose of this research is to give the clear picture of how ready textile-garment industry Indonesia to fulfil both of extensive demand from domestic and global market by adopting digital equipment, in this research digital textile printing. By elaborating all the considerations and factor, we are hoping that there would be identified root issues beneath of this industry and directly formulating the best approach and solution for this industry.

Autotrophic nitrogen removal for decentralized treatment of ammonia-rich industrial textile wastewater: process assessment, stabilization and modelling

Digital textile printing (DTP) is a game-changer technology that is rapidly expanding worldwide. On the other hand, process wastewater is rich in ammoniacal and organic nitrogen, resulting in relevant issues for discharge into sewer system and treatment in centralized plants. The present research is focused on the assessment of the partial nitritation/anammox process in a single-stage granular sequencing batch reactor for on-site decentralized treatment. The technical feasibility of the process was assessed by treating wastewater from five DTP industries in a laboratory-scale reactor, in one case investigating long-term process stabilization. While experimental results indicated nitrogen removal efficiencies up to about 70%, complying with regulations on discharge in sewer system, these data were used as input for process modelling, whose successful parameter calibration was carried out. The model was applied to the simulation of two scenarios: (i) the current situation of a DTP company, in which wastewater is discharged into the sewer system and treated in a centralized plant, (ii) the modified situation in which on-site decentralized treatment for DTP wastewater is implemented. The second scenario resulted in significant improvements, including reduced energy consumption (− 15%), reduced greenhouse gases emission, elimination of external carbon source for completing denitrification at centralized WWTP and reduced sludge production (− 25%).

Digital Textile Printing: A New Alternative to Short-Run Textile Printing in Ghana

This paper is a part of a broader research into textile design technology and trends across the world and their reflection on the local Ghanaian textile industry. It places conventional manual screen printing and digital textile printing technologies side by side and discusses the various drawbacks of screen printing as against the advantages of digital textile printing to illustrate a path for a wider consideration of the latter in Ghanaian small to medium scale textile production. Short-run textile printing commissions are the main source of jobs for small to medium scale textile producers in Ghana. And manual screen printing is the main process employed by these small-scale textile printers. However, screen printing has various layers of limitations such as poor registration of the design, stains, pinholes, colour correctness, colour consistency, colour smear, dye migration, scorching, improper curing, amongst others. These layers of limitations negatively affect the overall outcome of the prints. So, as it stands now, short-run textile printing commissions are either produced manually, of course, with several inconsistencies or outsourced to China and other countries at a higher production cost. This is because, the large-scale textile factories in Ghana could print a minimum of 2400 yards due to their machine settings, calibration and running cost to make the least returns. This study highlights some of the milestones in the development of digital textiles print machines and examines some of the key aspects of their tremendous production aptitudes for short-run textile commissions. The case study research method is used because data comes largely from documentation, archival records, interviews and physical artefacts.
