TLDR
In this article, two separate natural colorants were extracted from watermelon (Citrullus lanatus) rind (WRS) and flesh (WFS) for polyester coloration.Abstract:
The practice of natural colorants for polyester fabric dyeing has been rampantly rising in our consumer fashion. In this study, two separate natural colorants were extracted from watermelon (Citrullus lanatus) rind (WRS) and flesh (WFS) for polyester coloration. The optical and colorimetric properties of saps and dyed fabrics, dye fiber bonding phenomena, chromophores diffusion behaviors, color-fastness, ecological and economic aspects were examined through various analyses and the corresponding mechanisms were proposed. A wide range of chromophores diffusion was noticed for several parameter variations and the resulting diffusions were ranging from 42.67 to 83.13 %. Interestingly, WRS and WFS robust the UV shielding properties into the dyed fabric and the recorded UPF rating was found to be above 50. All color-fastness properties including sublimations were very good to excellent (4 to 4/5) except lightfastness. Finally, the ecological and economic aspects of WRS/WFS dyeing were also compared with commercial disperse dyes.read more

Environmentally Benign Dyeing of Polyester Fabric with Madder: Modelling by Artificial Neural Network and Fuzzy Logic Optimized by Genetic Algorithm
Aminoddin Haji,Morteza Vadood +1 more
Abstract: In this study, polyester fabric was dyed with madder as an environmentally friendly natural dye. According to Box-Behnken experimental design, 46 samples were dyed under various levels of five parameters including dye concentration, dyebath pH, temperature, time, and liquor ratio, and the color strength (K/S) of the dyed samples was measured. To evaluate the effect of each parameter on the color strength, the data was evaluated using multiple analysis of variance. Then, the artificial neural network (ANN) and fuzzy logic models were used to predict the measured K/S values. As both models contain different parameters, the genetic algorithm was implemented to optimize the model accuracy. It was observed that the best obtained ANN and fuzzy models can predict the K/S values with mean absolute percentage error of 2.52 and 3.01, respectively. Also, the effect of each input parameter on ANN was determined according to the partial derivative method and it was found that the maximum and minimum effects on ANN corresponds to dye concentration and liquor ratio, respectively. Finally, the effects of each dyeing parameter on the color strength was investigated based on the established optimal ANN model.
