It is important for researchers developing dyeing technology to improve the dyeing techniques of polyester micro fiber fabrics in terms of the time efficiency. The empirical observations have led to the deploying of the O-type dualnozzle flow dyeing machine developed by Asia Kingdom Machinery Industry Co., Ltd. to serve such purpose. The economic advantages include reducing the liquid ratio to 1: 8 and reducing the water volume required by 20~40%. The electricity required by 48~80% less compared to conventional upward or downward type dyeing machines. Therefore the CO2 production is decreased by 60%, demonstrating energy efficiency and environmental friendliness. The nozzle pressure of a single nozzle machine is 1.6~3.0 kg/cm 2 , whereas by adjusting the flux passing front and back nozzles, the dual nozzle pressure is maintained in the range of 0.2~1.6 kg/cm 2 . The reduced pressure decreases the frequency of yarn hairness occurrence, thus improving the dyeing quality. The low liquid ratio results in dye exchange increase by 1.3~1.66 fold, significantly increasing the uniformity. Despite 40 times fewer contacts between the nozzle and the fabrics (total 244 times) compared to conventional machines, similar results were observed.
In this study, improvement of the polarizer plate bubble in the thin lm transistor liquid crystal display process, especially where the polarizer plate is attached to the black matrix area at the end of the glass substrate, is presented. This study proposed temperature control functions during the attaching process using the preheating operations of pressure sensitive adhesives and a pre-existing warp polarizer plate. The polarizer plate is softened evenly, and, then, the bubbles can be discharged smoothly in the attaching process. Three main control factors are used in the polarizer plate attachment process, using an experimental design method, to determine the best combination of parameters. By applying optimal parameters in the experiments, bubble width can be decreased by 60.49%, compared with that of the previous process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
