Definition of Disperse Dyes s Compatibility by Principal Component Analysis Behnoush Yaraghi Yaraghi behnoush@royanchemie net Date of Submission 23th January 2013 Department of Textile Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor s Name Email Khalili@cc iut ac ir Abstract To research the behavioral conduct of dyes in a practical compound to achieve required leveling and confidence of requested shade repeat ability minimum amount of dye and consumable energy is essential During the recent years there have been tremendous changes in different industries and textile industry is no exception to these changes As the processing of dyeing become more complex due to decrease in its cycle control by computer to know more about the levels and methods seems to be necessary Therefore shorter dyeing cycles will increase production and decrease the level of chemical usage In addition to achieve leveling by adding chemical auxiliary increasing the temperature or maintain during long and additional hours has been kept a side and use of compatible dyes since rate of speed during the dyeing period there should be an equal percentage of exhaustion which is acceptable Incompatible dyes during different times of dyeing have attractive speed stroke and as a result produce an un level dyeing More over repeat ability can not be achieved The purpose of this research is a method to determine the compatibility of Disperse dyes in mixture based on the application of principal component analysis on the spectrum To achieve this purpose scalability of each dyes have been computed in different temperature and different time at highest temperature of dyeing cycle for three different shade according to standard depth of used dyes In order to eliminate the errors which originate from the non linearity of K S function against dyestuff concentration first the scalable region in the K S spectral data for used dyes has been determined as the priority by principal component analysis but the results did not limit to this region only Thereafter according to the quantity of absorbed dyes and rate of build up for disperse dyes toward used concentrated speed curve of dyes was achieved in pale medium and dark shade Afterwards speed curve of mixture samples were achieved in comparison on components dyes Finally by using principal component analysis on the K S spectral data the elements of data and eigenvalues have been PDF created with pdfFactory trial version www pdffactory com
