Figure 1. Drawing of a jigger, © Valdm. Henriksen A/S. 108 The machines were to be installed in a Danish dye-house and realistic trials were to be performed to document the possible savings when using the present technology. Jigger In 1995, the trial machine was installed in a dye-house, and extensive investigations were done by two engineer students as a graduate project. The principle provided the expected savings, and based on the good results, the machine was modified in such a way that further improvements could be achieved in respect to the rinsing efficiency and productivity. Result – Jigger Upon completion of the modification of the machine DTI Clothing and Textile carried out trials dated 95.10.03 and 95.10.05, report no. 350-4-0220.
Table 1. Documentation of savings in water consumption and process time on VH VACU-JIG 1200/2000 compared to conventional jiggers. Improved procedure Standard procedure Neutralization, 1 pass suction, spraying. Water consumption: 1030 L or 1,6 L/kg Time consumption: 17 min. Soaping 80°C, 1 pass suction, spraying. Water consumption: 820 L or 1,3 L/kg Time consumption: 20 min. Soaping 80°C, 1 pass suction, spraying. Water consumption: 470 L or 0,8 L/kg Time consumption: 19 min. Soaping 80°C, 1 pass suction, spraying. Water consumption: 80 L or 0,8 L/kg Time consumption: 19 min. Cold rinse, 1 pass suction, spraying. Water consumption: 740 L or 1,2 L/kg Time consumption: 18 min. Neutralization, 1 pass. Water consumption: 1560 L or 2,5 L/kg Time consumption: 17 min. Neutralization, 1 pass. Water consumption: 1560 L or 2,5 L/kg Time consumption: 17 min. Soaping 95°C, 2 passes. Water consumption: 1560 L or 2,5 L/kg Time consumption: 35 min. Soaping 95°C, 2 passes. Water consumption: 1560 L or 2,5 L/kg Time consumption: 35 min. Cold overflow rinse, 2 passes. Water consumption: 1400 L or 22,4 L/kg Time consumption: 35 min. Water consumption: 3540 L or 5,7 L/kg. Water consumption: 20240 L or 32,4 L/kg. Time consumption: 93 min. Time consumption: 139 min. Figure 2. Drawing of a jet. © Valdm. Henriksen A/S. As can be seen, the test passes resulted in water savings of 16.700 L or 82,5%. At the same time 3 passes were saved or 46 minutes or 33%. A copy of the report is available with Vald. Henriksen A/S. Jet A Dynawin jet was bought from Fong’s Nat. Eng. Co. Ltd. After fitting of a squeezing device at Vald. Henriksen A/S, the machine was installed in a dyehouse and trials were carried out. Result – Jet Trials were performed by DTI Clothing and Textile dated 95. 10. 10 report no. 350-4-0220. 109
