The Asante Kente is unquestionably the most popular and best-known of all African textiles. It has attracted the attention of many for centuries due to its uniqueness. The aesthetic appeal of Kente has been significantly improved over the years as a result of variations in design and production techniques. However, its design and production could be further improved and enhanced for the Asante Traditional Kente weaving industry to meet contemporary standards and market demands. Hence, this study sought to innovatively incorporate the Ikat technique – a patchy yarn dyeing decorative technique into the Asante traditional Kente weaving. The researchers utilized the studio-based research design under the qualitative research approach. The procedural steps in the Double Helix of Praxis-Exergesis Model which consisted of exploration, production, and evaluation, were adopted for the study. Personal interview was the principal data collection instrument used in collecting data from 12 purposefully sampled traditional Asante Kente weavers from six different communities in the Ashanti region of Ghana. The findings of the study revealed the possibility of fusing the two cloth production techniques to produce one common cloth that was named IKKente. The study recommends that this yarn decoration method should be encouraged among dyers and weavers to boost the local weaving industry in Ghana.

Recovering and reusing chrome from chrome effluent is critical for improving the mass balance of the tanning process and implementing the zero liquid discharge concept in the tanning industry. Conventional chrome recovery methods require a large amount of chemicals or energy to recycle the chromium. Chrome recovery by solar evaporation has not been implemented yet in the tanning industry. It is mainly practised in seawater salt extraction. In this study, we demonstrate the construction of highly efficient solar evaporators, using photothermal materials. Our focus is on efficient solar-to-vapour conversion and chrome recovery. The average evaporation rate was calculated and found 38.69 mL/hour, which remained almost steady within 2.5 months of data collection. The highest temperature observed during the process was 108 °C and 62°C in the focal region and condenser respectively. After collecting the solid chromium, basicity was measured at 85.02%, and treated with sulphuric acid to achieve 33% basicity. Recovered chrome and fresh chrome at 0:8, 5:3, and 8:0 were used for chrome tanning and tested for various chemical and physical parameters of tanned leather. The shrinkage temperature of the produced leather was found to be more than 100 °C. Physical characteristics such as tensile strength and percentage of elongation test, stitch tear strength, ball bursting strength and flexing endurance showed better results than conventional methods. This new kind of research offers a promising solution that can reduce the environmental impact of the tanning industry while also providing a sustainable source of chromium for a low-cost strategy and high-performance evaporation approach.

Designing the appearance of clothing can effectively enhance its attractiveness and expand its marketability. This paper briefly introduces the Convolutional Neural Network (CNN) and applies it to the recognition and evaluation of clothing pattern styles to assist in evaluating clothing appearance design. A case analysis was then conducted. Firstly, the CNN algorithm was compared with the traditional Back-Propagation Neural Network (BPNN) algorithm, and then the design scheme proposed in this paper, called "Sanduo and Jiuru", was evaluated. The results showed that, compared to the BPNN algorithm, the CNN algorithm not only converged faster during training but also demonstrated superiority after the convergence became stable. In addition, the test set also verified the accuracy of the CNN algorithm in recognizing and evaluating clothing pattern styles. The evaluation of the "Sanduo and Jiuru" design was also very similar to human evaluation, and its excellence was analyzed accordingly.

Chrome tanning is the most popular and widely used method utilizing basic chromium salts in leather processing. Only 60-70% of these salts react with collagen to form leather. The rest remains unreacted being released as toxic waste and causing severe environmental pollution in many developing countries. In the current study, a significant approach was made to utilize solid waste with a clean environment perspective. The chromium was extracted as basic chromium sulfate using H2SO4 from tannery waste and reused in the leather manufacturing procedure. Extracted solid sludge was examined by Atomic Absorption Spectrometry and elemental analysis before and after the separation of chromium (III). It revealed that 97% of chromium was extracted from tan yard sludge. Recovered chromium sulfate was reused in goat skin processing. Batch experiments were carried out by applying recovered basic chromium sulfate, and a combination of fresh and recovered basic chromium sulfate solutions separately. Fresh basic chromium sulfate was used as the control method. The structure and morphology of the final processed leather were characterized by Field Emission Scanning Electron Microscope (FESEM) and Thermogravimetric analysis (TGA). The identical structural morphologies of all processed leather were confirmed in the FESEM study. The physical and chemical characteristics of all finished leather were found very similar. The TGA analysis data proved that raw leather processed by recovered chromium is thermally more stable than others. These research findings signify a new potential effort of separating important chemicals from solid sludge and reusing them. This technique is simple, cost-effective, eco-friendly, and sustainable as it reduces environmental pollution from tannery chromium waste.

Spinning represents the foundational step in textile manufacturing, with yarn quality significantly influencing subsequent processes. Consequently, enhancing yarn quality remains a primary concern for spinners. Of various spinning techniques, ring spinning stands out for its blend of productivity and quality. The final ring yarn is produced by the ring frame, a machine encompassing multiple functional zones. A pivotal component within this frame is the spacer between the top and bottom aprons in the drafting zone. It modulates drafting pressure and fibre movement, directly affecting yarn quality. This research explored the impact of spacer size on yarn quality by employing seven distinct spacer sizes to produce 20 Ne cotton combed yarn. Results indicated that smaller spacer sizes often yielded inferior yarn quality. As the size increased, quality improved; however, after reaching an optimal size, further enlargement led to a decline in five key quality metrics: CVm (%), IPI, Hairiness, Tenacity, and Elongation %. This fluctuation can be attributed to changes in fibre movement and drafting pressure in the drafting zone. The study employed Interpretive Structural Modelling (ISM), a methodology grounded in expert opinions, to rank these quality parameters in importance. Through ISM calculations, yarn tenacity emerged as the most crucial quality parameter, aligning with its significance in producing woven fabrics. Furthermore, a Cronbach's Alpha score of 0.66 underscores the robust internal consistency and interrelation attesting to the study's reliability.

Wearable devices for gait measurement are devices worn on the body to measure the gait of the wearers. During gait measurement, several parameters are measured and the choice of parameters is influenced by the application and by extension the gait index. Two approaches have been adopted in this research. One is the provision of an overview of wearable devices for gait measurement with a bias towards textile-based “soft” smart wearable systems using information from varied academic sources and databases. The second approach is to map out key scientific research trends within the wearable device classes using the Web of Science database. The focus is to make a case for textile-based gait measurement devices and systems while exploring the key determinants of wearable gait sensor placements and application efficiency. These soft smart wearable systems describe flexible material sensor-based systems which have their sensing mechanisms based on material deformation after being subjected to stress or pressure. This study could therefore serve as an apt reference for the development of soft smart wearable gait measurement systems as it throws light on the various soft wearable gait measurement applications, the bottlenecks in soft wearable device design, opportunities for developing new devices and the merit that soft gait analysis systems possess over their hard gait measurement counterparts.

Tanning industries release chromium-based effluents directly into the environment putting the whole ecosystem at risk. As a result, the wastewater must be properly treated before being released. Reduced Graphene oxide (RGO), a graphene material having adsorption capacity, is prepared, characterized, and applied to Chromium (III) effluent (synthetic effluent-SE) to determine its efficiency and adsorption capacity (AC). RGO was characterized by TGA, SEM images, XDR, and FTIR analysis. It was a well-developed adsorbent because of its high thermal stability, wrinkled topology, the disappearance of broad peak at 2-theta angle 10.049° present in GO, and the presence of oxygen-containing functional group respectively. A batch experiment has been carried out at different adsorbent doses, contact times, and pH on the effluent. About 90.31% removal efficiency was found within 10 minutes when the absorption capacity was 180.61mg/g. Therefore, isotherm and adsorption kinetics of chromium ions on the RGO surfaces were studied to understand the different aspects of adsorption capability. The result showed that the process was favourable for adsorption. RGO suggested monolayer adsorption because it followed the Langmuir Isotherm more closely than the Freundlich isotherm model. Additionally, it was more compatible with the intraparticle diffusion (IPD) and pseudo-second-order (PSO) models. The findings demonstrated that RGO has great potential as an adsorbent for efficiently and swiftly removing chromium ions from wastewater.

Amidst mounting concerns regarding the health and environmental repercussions associated with synthetic agents, there has been a burgeoning interest in the exploration of natural dyes as a safer alternative. Derived from minerals, plants, and animals, these natural dyes have gained substantial traction due to their perceived eco-friendliness and reduced health risks compared to their synthetic counterparts. Notably, our study revealed significant enhancements in fastness properties across all mordanted samples, while those left un-mordanted exhibited notably inferior fastness properties. Among the mordants under investigation, potassium aluminium sulphate demonstrated appreciable stability characteristics, yet Citrus limon extract emerged as an even more effective mordant than potassium aluminium sulphate. The study also delved into evaluating the colour strength properties of the test samples, providing a comprehensive analysis of the Tencel fabric's overall dye performance and adherence to industry standards. In this research, a natural dye was extracted from the leaves of Azadirachta indica which was applied to Tencel fabric, which was then meta-mordanted with potassium aluminium sulfate and Citrus limon extract. The study explored various dyeing parameters, including diverse dye concentrations (7 g), dyeing temperatures (35, 50, and 65 °C) with a precision of ±1 °C, and dyeing durations (40, 55, and 75 minutes). The resulting samples were then subjected to testing against fastness properties, including washing fastness (ISO 106 C06), rubbing fastness (AATCC 8), perspiration fastness (ISO 105 E04) and Colour strength (K/S) of the Tencel fabric. The assessment of fastness properties was carried out using a grey scale.
