Book Description
With increased environmental awareness and rising costs, manufacturers are investing in real time monitoring and control of dyeing to increase its efficiency and quality. This book reviews ways of automating the dyeing process as well as ways of understanding key processes in dyeing, including dye transport in fluid systems. This understanding is then used to create models to simulate the dyeing process which can then be used to develop appropriate measurement and control systems. Control of variables such as temperature, pH, conductivity and dye concentration can then be used to ensure a more consistent and cost-effective dyeing process. - Reviews the dyeing process and dye house automation, and the factors that affect dyeing quality and common difficulties in the process. - Explains the principles underlying the dyeing process and provides a thorough understanding of the mathematical models that can be used to approximate it. - Discusses techniques for monitoring dyebaths and controlling the dyeing process.

Book Description
A project to develop a mathematical model capable of simulating the activities in a typical batch dyeing process in the textile industry is described. The model could be used to study the effects of changes in dye-house operations, and to determine effective guidelines for optimal dyehouse performance. The computer model is of a hypothetical dyehouse. The appendices contain a listing of the computer program, sample computer inputs and outputs, and instructions for using the model. (MCW).

Book Description
Fiber reactive dyes are important in dyeing textiles because they are unequally in their ability to confer bright wetfast shades on cotton fabric. While fiber reactive dyes are commonly employed for this purpose, the use of these dyes can introduce high costs and environmental concerns. For example, their fixation levels can be as low as 50% and high salt levels are typically needed to achieve desired shades. Thus, a mechanism for increasing fixation and exhaustion efficiencies in an economical way would enhance the value of these dyes to the textile industry. With these points in mind, researchers at North Carolina State University have studied a reactive dye modification that holds promise for achieving desirable exhaustion and fixation efficiencies. Specifically, the reactivity and affinity of some widely used dichlorotriazine (DCT) reactive dyes was enhanced using a straightforward 2-step process to convert commercial dyes to structures of types 1-4. In laboratory dyeing studying it was determined that type 2 dyes gave the best results in affinity and shade depth assessments. It remained to be shown that these dyes could be applied in an industrial dyeing setting. This thesis research focuses on applying the type 2 modified dyes in a commercial-scale manufacturing setting in order to further assess the benefits of the modified dyes. In preliminary studies, laboratory-scale dyeings were conducted to further investigate the color strength relationships between the modified and commercial dyes. As the main thrust of this research, dyeings were conducted in the pilot plant at North Carolina State University in order to simulate a production environment. An optimized batch dyeing procedure was developed for the application of the modified dyes, including optimal temperature, salt and alkali concentrations, time, and bath ratio. It has been found that level dyeings can be readily produced using industrial scale equipment, and there was no adverse change in fastness ar.

Book Description
Since process models are nowadays ubiquitous in many applications, the challenges and alternatives related to their development, validation, and efficient use have become more apparent. In addition, the massive amounts of both offline and online data available today open the door for new applications and solutions. However, transforming data into useful models and information in the context of the process industry or of bio-systems requires specific approaches and considerations such as new modelling methodologies incorporating the complex, stochastic, hybrid and distributed nature of many processes in particular. The same can be said about the tools and software environments used to describe, code, and solve such models for their further exploitation. Going well beyond mere simulation tools, these advanced tools offer a software suite built around the models, facilitating tasks such as experiment design, parameter estimation, model initialization, validation, analysis, size reduction, discretization, optimization, distributed computation, co-simulation, etc. This Special Issue collects novel developments in these topics in order to address the challenges brought by the use of models in their different facets, and to reflect state of the art developments in methods, tools and industrial applications.
