First-Order Parametric Model of Reflectance Spectra for Dyed Fabrics

Beer-Lambert-Law Parametric Model of Reflectance Spectra for Dyed Fabrics

Application of the Ratio Derivative Method in Quantitative Analysis of Samples Dyed with Ternary Dye Mixtures

In this study, a derivative method is applied for the determination of dye concentration in fabrics dyed with tricomponent dye mixtures. The reflectance of spectra of the samples were recorded between 400 and 700 nm. Initially, the obtained (K/S) spectra were divided by the spectrum of a standard sample dyed with two of the components in the ternary mixture and the derivative spectra were calcu...

Effect of Abrasion Process on Reflectance Factor and Color Change of Chenille Woven Fabrics

This paper focuses on effect of abrasion process on color and reflectance factor changes of dyed woven fabrics containing 100% acrylic chenille yarns in weft and cotton warp yarns. Three fabrics having 12, 14 and 16 weft per centimeter were dyed with three basic dyes in different hues. Four different abrasion levels, i.e. 50,200,400 and 650 were selected to abrade samples. The obtained results ...

Spectral Reconstruction of Blacks and Whites by Using the Statistical Colorants

In this paper, the spectral dimensions of two sets of samples including 457 black and 84 white fabrics are compared. White fabrics are treated with variety of fluorescent whitening agents and the blacks are fabrics that dyed with different combinations of suitable dyes and pigments. In this way, the reflectance spectra of blacks as well as the total radiance factors of whites are compressed in ...

Studies on UV-Visible, Fluorescent Spectral Properties and Solvatochromic behavior of Naphthalimide Compound Containing Quaternary Ammonium

This paper presents the results of absorption spectra, fluorescence properties and the effect of solvents on UV-Vis spectra of dye quaternized 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide. The fluorescency of the dye was evaluated and its Stokes shift value was 6140 cm-1 in DMF. The solvatochromism behavior of the novel compound is investigated by studying its spectra in pure organic...
