This study aims to investigate into the adsorption mechanism of heavy metal ions Pb²⁺ and methylene blue (MB) dyes on an adsorbent-web formed from kapok fibres (KP) and polypropylene fibres (PP).

Initially, the KP underwent pre-treatment with NaClO₂ solution, and their morphology and structure changes were examined through scanning electron microscope images. Subsequently, the KP fibres were blended with PP fibres at a ratio of 70 / 30 and processed through a laboratory carding machine to form a fibre web, which was then secured using a heat press to fabricate the adsorbent-web. The resultant adsorbent-web was subjected to evaluation for the adsorption process.

The findings revealed that the adsorbent-web produced via the dry-laid method exhibited promising attributes, and the adsorption process conformed to the pseudo-second-order model and the Langmuir isotherm model. Parameters such as adsorbent-web porosity, solution pH, and adsorption thermodynamics exerted notable influences on the adsorption capacity of the adsorbent-web. Notably, the adsorbent-web demonstrated remarkable reusability and desorption capacity. In the fifth cycle, the adsorption capacity of adsorbent-web for MB and Pb²⁺ ions only decreased by 9.13% and 11.48%, respectively, compared to the first cycle. The desorption efficiency of the adsorbent-web exceeded 90% for MB and over 73% for Pb²⁺ ions.

This study makes a significant contribution to the practical application of KP as an adsorbent-web for treating waste from the textile dyeing industry.

In the apparel industry, suppliers play a significant role, directly affecting customer service levels and business profits. Integrating sustainable requirements into supplier selection not only aligns with global environmental goals but also enhances business performance, social responsibility and overall industry well-being. This study aims to design a multi-criteria model to evaluate and select the most sustainable suppliers in the fashion industry, trying to balance the conflicts in the set of sustainable development criteria.

The integration of analytic hierarchy process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) offers advantages in sustainable supplier selection within the apparel industry. The AHP plays a crucial role in engaging multiple decision-makers with conflicting criteria to reach a consensus during the decision-making process. Conversely, the TOPSIS is used to compute alternative ratings. By simultaneously determining criteria weights and incorporating stakeholder preferences, hybrid models enhance decision-making strength and overcome limitations observed in classical multi-criteria decision-making techniques.

This research identified and classified 16 critical criteria impacting the selection of apparel industry suppliers, focusing on sustainable development. The criteria were weighted, providing a robust statistical foundation for the selection model. The results indicated that the most influential criteria were staff training, production capability, flexibility and practice of recycling. The proposed sustainable supplier selection model explains to decision-makers how criteria influence supplier ranking results compared to traditional models, supporting managers in making informed and sustainable supply chain decisions through continuous updates and enhancements.

This research provides new insight into the weighted impact of factors related to sustainable supplier selection in the apparel industry. The combination of a precise process and scientific knowledge will improve the quality of sustainable supplier selection.

Kapok was well-known for its oleophilic properties, but its mechanical properties and morphology impeded it from forming suitable absorbent materials. This study aims to demonstrate the process of creating an oil-absorbent web from a blend of treated kapok and polypropylene fibers.

Kapok fibers were separated from dried fruits, then the wax was removed with an HCl solution at different concentrations. The morphological and structural changes of these fibers were investigated using scanning electron microscopy images. The blending ratios of kapok and polypropylene fibers were 60/40, 70/30 and 80/20, respectively. The fiber blends were fed to a laboratory carding machine to form a web and then consolidated using the heat press technique. The absorption behavior of the formed web was evaluated regarding oil absorption capacity and oil retention capacity according to ASTM 726.

The results showed that the HCl concentration of 1.0% (wt%) gave the highest wax removal efficiency without damaging the kapok fibers. This study found that oil absorbency is influenced by the fiber blending ratio, web tensile strength and elongation, porosity, oil type and environmental conditions. The oil-absorbency of the web can be re-used for at least 20 cycles.

This study only looked at three types of oils: diesel, kerosene and vegetable oils.

When the problem of oil spills in rivers and seas is growing and causing serious environmental and economic consequences, using physical methods to recover oil spills is the most effective solution.

This research adds to the possibility of using kapok fiber in the form of a web of non-woven fabric for practical purposes.

This study proposes a serial mediation model to investigate the factors influencing hospitality and tourism (H&T) students' destination choice intentions in an experiential learning context. By extending the theory of planned behavior (TPB) model to include extended variables and the stimulus-organism-response (S-O-R) theory, this study explores pathways in which experiential learning involvement (IEL) and destination emotions (DE) interact with attitude (ATT), subjective norms (SN) and perceived behavioral control (PBC) to predict H&T students' intentions (ITT). This work also examines the moderating role of destination familiarity (DF) on relationships between destination emotions and attitudes, subjective norms and perceived behavioral control.

The conceptual model and research hypotheses were each assessed using partial least squares structural equation modeling (PLS-SEM). Paper-based surveys were used to collect data from 715 students majoring in tourism and hospitality training at schools in Vietnam and applying experiential learning activities during their training.

Research results confirm a serial mediation model wherein IEL and DE promote the formation of intention to choose a specific destination through various pathways: IEL? PBC? ITT; IEL? DE? SN/PBC? ITT and DE? SN/PBC? ITT. In addition, the results show that destination familiarity dampens the relationship between emotions and attitudes as well as with perceived behavioral control.

This study offers practical recommendations for destination management organizations (DMOs) seeking to increase the intention of H&T students to choose their particular destination. These recommendations include: forming strategic alliances with H&T educational institutions; implementing preferential policies like discounted or free admission to attractions and corporate discounts for students; launching targeted digital marketing campaigns on social media platforms and promoting the destination through youth-oriented media such as television shows and music videos.

From addressing the research gap by developing and testing a serial mediation model of destination choice intention of H&T students in an experiential learning context, this study offers new insights into developing scales of constructs in the research model associated with the context of experiential learning and highlights the importance of IEL and DE as a stimulus to achieve ATT, SN and PBC, all of which serve to increase H&T students' intention to choose a destination through different paths under the moderating lens of destination familiarly.

This research aims to investigate the relationship between value orientations, attitude, behavioral intention and usage behavior of electric ride hailing service in Vietnam through the moderating role of social influences.

In total, 552 valid questionnaires were collected using the survey questionnaire to analyze the effects of value orientations on attitude toward electric ride hailing and behavioral intention. Besides, this study investigates the mediating effect of attitude toward electric ride hailing and behavioral intention in the relationship with the behavior usage of electric ride hailing service as well as the moderating effect of social influence.

Three types of value orientations stimulate attitude toward electric ride hailing service and behavioral intention. In addition, attitude toward electric ride hailing service and behavioral intention play the mediating role in the effect of value orientations on behavior usage. Specifically, social influence plays a negative moderating role in the linkage between attitude towards and behavioral intention of electric ride hailing service and between intention and the behavior usage.
