Summary: Considering the importance of natural colorants and sustainable products, researchers focused on new color resources, identification, and standardization of natural dyes. They extracted natural colorants from Ziziphus bark using ultrasound technique and applied them to wool yarn to produce antioxidant and antibacterial fibers. The optimum conditions for extraction were determined, and the effects of temperature, dye concentration, dyeing time, pH, and L.R ratio on the wool yarn were investigated. The Ziziphus dye showed a significant reduction in Gram-negative and Gram-positive bacteria and exhibited antioxidant properties on the wool yarn.

Summary: This study investigated the microwave-assisted isolation of Alkannin dye from Alkanna tinctoria and its application in dyeing bio-mordanted silk. Different extracts and microwave treatment times were used to observe the dyeing effects. The use of bio-mordants ensured an eco-friendly and clean dyeing process. The acid solubilized extract showed higher color strength under specific conditions. Colorfastness tests indicated that bio-mordants outperformed chemical mordants in terms of color depth and fastness. The study demonstrated that microwave-assisted dyeing improved the dyeing performance, and the use of bio-mordants enhanced the color characteristics of silk fabric dyed with Alkanna tinctoria extract.

Summary: The textile industry, known for its materials and chemical processes derived from petroleum and the environmental issues it poses, seeks new possibilities for more sustainable alternatives. This study explores the use of natural dyes in the dyeing of Alanya silk, utilizing plants like crocus sativus, Helichrysum arenarium, and Glycyrrhiza glabra L. grown in the Alanya region. Quercus aegilops L. from the region, known for its high tannin content, was used as a natural binder instead of chemical mordants for a more environmentally friendly approach. The study concludes that dyes made with Glycyrrhiza glabra L. performed the best in terms of color fastness and efficiency.

Summary: This study optimized the dyeing parameters for wool using Berberis thunbergii DC leaves as a natural dye source, aiming to introduce a new sustainable coloration process. The results showed that increasing dye concentration and dyebath temperature increased color strength (K/S), while increasing dyebath pH and mordant concentration decreased K/S. The optimal pH, dye concentration, dyeing temperature, and mordant concentration for achieving the highest K/S were 5, 146%owf, 76°C, and 3.8%owf, respectively. The samples dyed under the optimal conditions exhibited good color fastness properties.

Summary: Recent trends show an increase in the use of natural dyes, despite the high production cost. This study focuses on converting waste from saffron flowers into an eco-friendly dye for wool fabric. Through various analyses, it is found that saffron flower extract (SFE) is stable under acidic conditions and suitable for textile dyeing processes. By optimizing dyeing conditions, a range of colors with good color fastness are obtained, showing the potential of SFE as a natural textile dyestuff.

Summary: In this study, pomegranate peel extract was used to dye cotton fabrics. Air atmospheric plasma treatment was applied to lower the concentrations of mordants and enhance dyeability. The outcomes showed a decrease in residual metallic ion concentrations. ATR-FTIR and SEM analysis evaluated the effect of plasma modification on the surface chemistry and topography of the fibers. Color fastnesses were good to very good. Plasma treatment is an efficient strategy for reducing toxic metallic mordant concentrations.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
