Determination the capabilities and limitations of the Beer Lambert s Law Exhoustion Prediction of Dyes and Using Spectral Data for calculation Mehdi Azad Khankandi Mehdiazadkhankandi@gmail com Date of Submission 2013 1 21 Department of Textile Engineering Isfahan University of Technology Isfahan 8415683111 Iran Degree M Sc Language Farsi Supervisor H Khalili khalili@cc iut ac ir Abstract In textile industry dye behavior such as Exhaustion Rate of dyeing and consistency dyes are highly regarded It should be noted that the factors to be measured somehow Hence classical methods absorptiometry in the textile industry has been particularly important Despite the usefulness of capabilities method classical absorptiometry this approach also has limitations which can cause errors in trials and reviews Classic absorptiometry methods commonly when high concentrations of dye in dyeing disperse dyes and fluorescent properties are dyes be used or when the solution of air bubbles or Non uniformity is created with errors and the results are false Hence the use of other methods such as spectroscopic method is used Unlike absorptiometry methods in the study of materials solutions are used in textile dyeing technique spectroscopic studies have been focused on It is worth noting that despite spectroscopic method also has the capabilities limitations that are caused by errors in reviews This study examines the capabilities and limitations of the Beer Lambert Law and compare this method with spectroscopic results are discussed Factors that are examined include classical methods absorptiometry The designated maximum wavelength of each dye the calibration curve for each dye textile dyeing wool and nylon with single and blend color and dual dye concentration estimates and determine the equation of rate dyeing and repeatability tests The molar absorption coefficient of each dye method absorptiometry Classic must be determined by using the least squares technique To estimate the concentration of dye uptake in textile dyeing single colors and estimate and measure the draw caught on concentration and Equation to determine the rate of dyeing techniques and least squares calibration curve is used In order to estimate the concentration and decisive moments in the drawing binary combination dyeing dye only the least squares technique is used The tests are performed in survey absorption spectrophotometry also be repeated with slight differences Differences in testing and calculation methods of absorption spectroscopy is a classic survey include How do changes in speed test dyeing the K S instead of the molar absorption coefficient using a technique the technique of least squares the estimated concentration instead of the two techniques least squares techniques and calibration curve In both methods with the help of MATLAB and Excel calculations have been carried out Finally this study conducted experiments to compare the results of two polls absorption spectroscopy and classical and error factors are also studied Studies show that some dyes and other dyes absorption spectrophotometry survey results have been good Key words Classic absorptiometry The Beer Lambert Law The spectral data Acid dyes Disperse dyes
