Optimization of the Dyeing Process and Prediction of Quality Characteristics on Elastic Fiber Blending Fabrics

This study aims to find the optimal conditions for dyeing polyester (PET) and Lycra®-blended fabric and predict the quality characteristics, where PET and Lycra®-blended fabric were taken as raw material with dispersed dyes using a one-bath two-section dyeing method, characterizing the color strength of gray fabric. Adopting the Taguchi method for parameter design, machine working temperature, dyeing time, dye concentration, and bath ratio, which have an influence on dyeing, were chosen as control factors to conduct experiments using orthogonal arrays, and analysis of variance was incorporated to determine optimal processing conditions, significant factors, and percent contribution. With the smaller-the-better characteristic for color strength of gray fabric as the target characteristic, calculations were conducted to confirm the reproducibility of the experiment. We found from experimental results that color strength for gray fabric dyed under optimal conditions was closer to the target value. In addition, we constructed a prediction system based on the factors significantly influencing dyeing performance by a integrating genetic algorithm (GA) with a back propagation neutral network (BPNN), so as to find optimal connection weight values. Hence, learning algorithm efficiency was enhanced with decreased dependency on initial conditions, together with a more robust learning algorithm, so as to predict color strength for gray fabric. Moreover, improvements of BPNN, which is most widely used at present, will be influenced by choice of initial learning parameters more often than not, hence there is a disadvantage in that it is probable that only local optimal solutions are found instead of global optimal solutions.

The effect of finishing on the mechanical and thermal properties of wool fabrics. Part1-the properties of piece-dyed fabrics

Changes in the handle-related deformation properties of wool fabric following piece dyeing were found to be related to the set imparted by the dyeing operation, and resulted primarily from dimensional changes in the fabric. When dyeing imparted large amounts of set to the wool, increased contraction during drying resulted in a heavier, more extensible fabric. Inhibiting set by dyeing at low pH, or by dyeing in the presence of an oxidising agent or cross-linker, reduced the effect. Objectively measured fabric surface properties and subjective assessment of smoothness were little affected by the conditions of dyeing and were far more dependent on the dry-finishing method used to set the fabric and, to a lesser extent, on the method used to pre-set the fabric prior to dyeing. The effect of extended dyeing on the mechanical properties of the fabric depended not only on the pH of dyeing but also on the nature of the dyeing machine.     

Applying the Taguchi method to examine the optimal parameters of cotton fabric dyeing by biodegradable surfactant

Wastewater from the cotton fabric dyeing process causes high levels of environmental pollution. In order to address this problem, this study used a series of biodegradable surfactants in cotton fabric dyeing and applied the Taguchi method to analyse the optimal parameters of cotton fabric dyeing by such surfactants. The test parameters included the hydrophobic group chain length of the surfactant, and surfactant concentration and the processing time. This study calculated the signal‐to‐noise ratio of the experimental results by the‐larger‐the‐better characteristic and applied analysis of variance to discuss its impact on the dyeing results. The results confirmed that the most important influential factor is processing time, followed by surfactant concentration. Moreover, the addition of surfactant could promote a dyeing effect during processing.

Carrier‐free dyeing of radiation‐grafted polyester fabrics with disperse dyes

Carrier‐free dyeing of radiation‐grafted polyester fabrics with disperse red dye was studied in the temperature range 283–363 K. 1‐vinyl 2‐pyrrolidone (NVP), acrylic acid (AA) or their mixture was used to graft poly(ethylene terephthalate) (PET) fabric. The effects of pH of the dye solution, graft yield (GY), dyeing time (t), dye concentration (C), and dyeing temperature (T) on the colour difference (CD) of PET fabric were studied. The best dyeing condition was achieved at pH 5.5. CD increases linearly with the increase in GY, with slopes depending on the type of grafted copolymer. CD increased rapidly as the dyeing time increased; this was followed by a relatively slow dyeing rate within a few minutes. The initial dyeing rate (R) was found to increase with an increase in C and T. The dyeing rates for all grafted samples followed 0.35‐order kinetics and are temperature‐independent. Average activation energy 9.26 kJ mol^?1 is calculated for the dyeing process and is independent of the fabric treatment. Pre‐exponential rate constants 1976, 1839, and 1579 (CD/GY) s^?1 were calculated for dyeing PET samples grafted with AA/NVP mixture, NVP and AA, respectively, while 1074 CD s^?1 was evaluated for carrier dyeing of ungrafted fabric. Analysis of the kinetic parameters and the dyeing mechanism revealed that dyeing PET fabric was diffusion‐controlled. Grafting PET fabric improved significantly the dyeing affinity of the DR dye over ungrafted samples dyed in solutions containing a carrier. Copyright © 2005 Society of Chemical Industry     

Dyeing of silk fabric with phenazine from Pseudomonas species

Phenazines, namely oxychlororaphin and pyorubin, were extracted from Pseudomonas sp., purified and their dyeing potential as colorants for silk dyeing were examined. The effects of the process variables, such as phenazine concentration, pH, temperature, time, type of mordant, relative colour strength and fastness properties have been studied. The results showed that the optimum condition for dyeing was 90 °C at pH 3 and dyeing time 90 min for oxychlororaphin, and 70 °C at pH 3 and dyeing time 60 min for pyorubin. The K/S value of a pre‐mordanted silk fabric with oxychlororaphin was high when compared to that with the pyorubin. The antimicrobial activity of a dyed silk fabric was tested against Salomonella paratyphi, Escherichia coli and Shigella flexneri.
