Study on the Damaging of Dyed Cotton Fibers with Direct Dye in Spinning Processes and its Effect on the Properties of Cotton Mélange Yarn
The influence of dyeing and spinning on the characteristics of cotton fibers and its impact on the properties of cotton mélange yarn has been investigated. Grey cotton fibers with mean fiber length and fineness of 29 mm and 4.2 micronair were pre-treated and dyed. Three ring yarns were spun from 100 % grey cotton (R.R.Y), 50-50 % blend of dyed and grey cotton (M.R.Y) and 100 % dyed cotton fiber...
متن کاملApplication 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...
متن کاملThe analysis of colored acrylic, cotton, and wool fibers using Raman spectroscopy
There has been a resurgence in Raman spectroscopy for its application in forensic science. This method allows for the measurement of the inelastic scattering of light due to the vibrational modes of a molecule when irradiated by an intense monochromatic source such as a laser. The Raman technique presents advantages such as its non-destructive nature, its fast analysis time, and the possibility...
متن کاملWash Fastness of Textile Fibers Dyed with Natural Dye from Eucalyptus Wood Steaming Waste
Natural dyes are gaining interest due their expected low risk to human health and to the environment. In this study, the wash fastness of a natural coloring matter from the liquid waste produced in the steam treatment of eucalyptus wood in textile fabrics was investigated. Specifically, eucalyptus wood extract was used to dye cotton, nylon and wool in an exhaust dyeing process without the addit...
متن کاملpart a: application of n-(p-toluenesulfonyl) imidazole (tsim) and triphenylphosphine/carbon tetrachloride in several organic transformations part b: application of 8-bromocaffeine for synthesis of some novel 8-caffeinyl derivatives
بخش اول این پایان نامه به طور عمده بر توسعه کاربردهای جدید n-(پارا-تولوئن سولفونیل) ایمیدازول (tsim) و تری فنیل فسفین/ تتراکلرید کربن در تبدیل گروههای عاملی به یکدیگر استوار است. نظر به تنوع زیاد، دردسترس بودن، سمیت کمتر و نقل و انتقال آسان تر الکل ها نسبت به آلکیل هالیدها، تبدیل مستقیم گروه هیدروکسیل به گروه های عاملی دیگر مثل آزید، نیتریل و استر یکی از مهم ترین تبدیلات در سنتزهای آلی است. با ...
