Interaction between the Surface Properties of the Textiles and the Deposition of Cationic Softener
Journal of Surfactants and Detergents, 2012Co-Authors: Gaurav Agarwal, Anne Perwuelz, Ludovic KoehlAbstract:In this study we categorised the surface properties of different knitted fabrics by their electro-kinetic behaviour and liquid up-take phenomena of the knitted textiles in order to understand the interaction of the surface properties of the textiles with Cationic Softener deposition. The electro-kinetic and liquid uptake properties of textiles were measured by their zeta-potential and liquid absorption ability. We also examined the influence of fabric Softener on the surface characteristics of the textiles. We used solvent extraction followed by Cationic titration to determine the Cationic Softener level present on the textiles. The major finding of this study was the different behaviour of individual loads and mixed loads in terms of Cationic pick up from the rinse cycle Softener. Fibre type plays the most critical role in determining the zeta potential of the fibre, filtration efficiency and water retaining capability of the fabrics, which in turn play the most important role in Softener deposition on the textile. The charge on the textile surface is negative; this plays a key role in the deposition of the Cationic Softener in both kinds of loading conditions. Capillary diffusion could be a key parameter only in the individual load condition. It was found that there is a significant reduction in the liquid adsorption weight when fabrics are treated with levels of Softener that are much higher than those associated with normal consumer use. As soon as the fabric comes into contact with the liquid, the fabric Softener molecules transfer from the fabric to the liquid and reduce the surface energy of the liquid. This results in an increase in the wetting weight of the fabric.

sensory study of knitted fabrics that have gone through washing cycles with domestic Softener part i establishment of a panel and assessment thereof
Fibres & Textiles in Eastern Europe, 2011Co-Authors: Gaurav Agarwal, Ludovic Koehl, Anne PerwuelzAbstract:This study involved the sensory evaluation of knitted textiles which have gone through different domestic laundering treatments with respect to whether their sensory attributes or a combination of different measured sensory attributes can best predict the preference of consumers in the aspect of comfort . The textile consumer always has specific preferences which are related to textile properties at the time of purchasing textiles and also to the perception of how long lasting these properties will be. In the large competitive market of Softeners, all Softener producers claim the improvement of fabric hand as well as the mechanical properties of textiles. The main aim of this study is to find the important sensory parameters enhanced by the use of Softener during washing and the impact of repeated washing on sensory attributes. The study is based on Cationic Softener (rinse cycle type). We also examined the change in the handle of fabric using the fabric life cycle. The change in the handle of fabric after washing is unavoidable because of strong mechanical action during washing, but it can be improved with the use of domestic Softeners during the rinse cycle. In Part I, we established a panel for the sensory evaluation of knitted fabrics that have gone through the ageing of washing cycles with/without the use of fabric Softener. The panel assessed the fabrics using criteria defined by the author. In part II, we will discuss the influence of ageing during the washing cycle and the use of fabric Softener on sensory properties.

the influence of constructional properties of knitted fabrics on Cationic Softener pick up and deposition uniformity
Textile Research Journal, 2010Co-Authors: Gaurav Agarwal, Ludovic Koehl, Anne PerwuelzAbstract:In this study we tried to find the influence of fiber type, fiber fineness and knit construction on the amount of Softener pick up by the fabric. Decision trees are developed to explain the Cationic Softener pick up depending upon the factors mentioned above. The influence of the type of load (mixed fiber load and individual fiber load) on the amount of Softener deposited on the fabric was also studied. We have also quantified the non-uniformity of Softener deposition. We used an image-processing tool to define non-uniformity of the Softener deposition. It evaluates the spatial uniformity of Softener deposition by evaluating the difference between observed patchy distribution and a random process which would lead to a uniform distribution.

novel Cationic Softener containing mct reactive dyes for cotton simultaneous dyeing and functional finishing
Fibers and Polymers, 2013Co-Authors: Marzieh S Javadi, Javad Mokhtari, Mahdi Nouri, Firouzmeh MazaheriAbstract:The Cationic Softeners containing MCT (monochloro-s-triazinyl) reactive dyes were employed on the dyeing of cotton fabrics. The substantivity, exhaustion, and fixation of the dyes were investigated. It was found that these functional dyes could be effectively introduced to cotton fibers to achieve simultaneous coloration and functional finishing effects. All the dyed fabrics exhibited softening efficacy. The dyes offered excellent washing fastness on cotton substrate. Light fastnesses of the dyes on the substrate were poor.

novel Cationic Softener containing mct reactive dyes for cotton synthesis and characterization
Fibers and Polymers, 2013Co-Authors: Marzieh S Javadi, Javad Mokhtari, Mahdi Nouri, Mohammad J MehdipouAbstract:Two novel Cationic Softener containing mono-s-chloro triazinyl reactive dyes together with their analogues were designed. The dyes were synthesized via reacting an N,N-dimethyldodecylamine with p-nitrobenzyl bromide. The resultant was reduced using stannous chloride and hydrochloric acid to produce the primary amine. The quaternary ammonium salt containing primary amine was then diazotized to produce diazonium salt part of azo dye. The diazonium salt was then coupled to H-acid/J-acid reacted with cyanuric chloride and sulfanilic acid. The analogue dyes were prepared via the same route without quaternary ammonium salt making stage. The chemical structures of the novel dyes were characterized by FTIR, 1H-NMR, and elemental analysis. The spectroscopic properties of the dyes were determined in terms of λ max and ɛ max in aqueous solution.
