Impact of Environmental Factorson Supply Chain Practices in Textile Sector

In today's era, supply chain functions play a significant role in every business model, whether service-based or product based. Effective and efficient supply chain practices help the business grow, provide value to its buyers, and help make rational decisions that encompass the nation's economic, social, and environmental benefits. These supply chain functions can only be implemented and provide sustainable benefits if no direct or indirect disruption is inferred due to internal or external environmental factors. Our nation's textile manufacturers and exporters are the primary sources that propel the nation's economy. In short, the textile industries drive ninety per cent of the economy. Eventually, their supply chain practices are surrounded by many factors, which lead them to run or halt their operations. If we enlighten the past, a major global environmental factor, significant supply chain disruptions occur and especially strikes our country's primary economy-driven sector. It is a cross-sectional study. The present study was conducted in the urban areas of Karachi, Pakistan. Data collection will be through questionnaires and surveys. It is designed for information collection so it can use to determine the impact of this factor in significant supply chain functions, including procurement, warehousing, logistics, and import & export.

Environmental friendly pollution free bio-dyeing of wool with haar singhar (Coral Jasmine) flower extract.

The world's move towards revival of eco-labelled products has created a huge urge to explore new means which are healthier for the global community. Among such means, plant-based bio-pigments for coloration of matrix are gaining worldwide fame, particularly in the textile sector. For the purpose of appraising new source of eco-friendly dyes, using microwave irradiation techniques, Coral Jasmine flowers have been explored for the bio-dyeing of wool. The colorant was extracted in acidic medium owing to nature of fabric, and both stuffs have been exposed to microwave treatment up to 5min. Bio-coloration of MW irradiated and unirradiated wool was done using MW irradiated and unirradiated extract for observing high yield. Central composite design (CCD) as statistical method was utilized to see the significance of dyeing parameters chosen for mordanting to develop colorfast shades. Different concentrations of sustainable chemicals and bio-mordants as per weight of fabric were employed to introduce new shades with improved colorfastness properties. International standard textile methods determining shade permanency (fastness) have been employed onto selected dyed-mordanted fabrics. Good yield of colorant was observed when MW irradiated wool fabric was dyed at 75°C for 45min with extract of 7pH, having 1.5g/100mL of salt solution; the promising color yield was observed. As per gray scale ratings observed after ISO standard methods, pine nut as bio-mordant and iron salt as chemical mordant have developed colorfast shades. Conclusively, it can be recommended that methods for the isolation of colorants from new dye yielding plants, MW heating method as suitable clean technology and medicinal-based bio-mordants should be employed for getting permanent gamutes.

Bacillus subtilis: As an Efficient Bacterial Strain for the Reclamation of Water Loaded with Textile Azo Dye, Orange II

The azo dye orange II is used extensively in the textile sector for coloring fabrics. High concentrations of it are released into aqueous environments through textile effluents. Therefore, its removal from textile wastewater and effluents is necessary. Herein, initially, we tested 11 bacterial strains for their capabilities in the degradation of orange II dye. It was revealed in the preliminary data that B. subtilis can more potently degrade the selected dye, which was thus used in the subsequent experiments. To achieve maximum decolorization, the experimental conditions were optimized whereby maximum degradation was achieved at: a 25 ppm dye concentration, pH 7, a temperature of 35 °C, a 1000 mg/L concentration of glucose, a 1000 mg/L urea concentration, a 666.66 mg/L NaCl concentration, an incubation period of 3 days, and with hydroquinone as a redox mediator at a concentration of 66.66 mg/L. The effects of the interaction of the operational factors were further confirmed using response surface methodology, which revealed that at optimum conditions of pH 6.45, a dye concentration of 17.07 mg/L, and an incubation time of 9.96 h at 45.38 °C, the maximum degradation of orange II can be obtained at a desirability coefficient of 1, estimated using the central composite design (CCD). To understand the underlying principles of degradation of the metabolites in the aliquot mixture at the optimized condition, the study steps were extracted and analyzed using GC-MS(Gas Chromatography Mass Spectrometry), FTIR(Fourier Transform Infrared Spectroscopy), 1H and carbon 13 NMR(Nuclear Magnetic Resonance Spectroscopy). The GC-MS pattern revealed that the original dye was degraded into o-xylene and naphthalene. Naphthalene was even obtained in a pure state through silica gel column isolation and confirmed using 1H and 13C NMR spectroscopic analysis. Phytotoxicity tests on Vigna radiata were also conducted and the results confirmed that the dye metabolites were less toxic than the parent dye. These results emphasize that B. subtilis should be used as a potential strain for the bioremediation of textile effluents containing orange II and other toxic azo dyes.

Exploring the mediating role of knowledge management practices to corporate sustainability

This study aims to elaborate and recognize a model in which knowledge management practices affect corporate sustainability via corporate structure, corporate culture, corporate leadership style, and a unique variable social capital, used for the first time. Knowledge management is now used as a mediating variable for corporate sustainability. Creating long-term sustainable strategies emphasizes the need for a distinctive model of knowledge management practices in a rapidly changing business environment. Therefore, this paper delivers insights on how an organization can sustain its performance by addressing new dimensions due to the changing socio-economic environments and the pursuit of incessant improvement of competition. The authors used a quantitative research approach. Data is collected through a well-designed questionnaire from 130 respondents from Dhaka's textile sector, a significant sector of Bangladesh's economy and the world's second-largest ready-made garment (RMG) manufacturer and exporter. The result revealed that corporate sustainability is significantly related to corporate structure, culture, social capital, and corporate leadership styles. The mediated role of knowledge management in the link between organizational culture and sustainable performance is also crucial, and the relationship between leadership style and sustainable performance is also vital. A new variable known as social capital is also identified. Giving value and novelty to the academic literature also confirmed knowledge management and corporate sustainability theories that governments and regulators should follow.

Technical Education in Nara Japan: Text and Context of the Yōshi kangoshō (ca. 720)

Abstract The Yōshi kangoshō (Notes on Chinese Words by Master Yako, ca. 720) is a bilingual Sinitic-Japanese dictionary, now lost and surviving only in indirect transmission thanks to quotations in the Wamyōruijushō (Categorized Notes on Japanese Nouns, ca. 934) by Minamoto no Shitagō (911–983). The lexical domains covered by the Yōshi kangoshō deal with technical knowledge, such as terminology for anatomy and medicine, archery, constructions, shipping and shipbuilding, the textile sector (clothes, belts, shoes, sewing, weaving, sericulture, dyeing, etc.), hippology and stock-breeding, agriculture, cooking, carpentry, sea and earth products, kinship. In this paper, I propose a reconstruction of the Yōshi kangoshō, furnishing the complete list of its quotations. I would therefore like to propose that the Yōshi kangoshō should be reconsidered as an educational tool for learning terminologies, and that it was particularly useful for the technical education of clerks.

Circular Economy Guidelines for the Textile Industry

The production of textiles has a strong impact on the environment due to both over-consumption and the practice of production processes requiring the use of substances to manufacture, treat, and dye fabrics. In this context, finding new ways and solutions to transform used textiles into by-products or inputs for production is a trump card for the future of the textile sector. This may be accomplished by developing a circular economy policy, which involves large investments with a payoff only in a medium to long-term perspective. The main aim of the present work is to provide a set of guidelines to guide textile industries in the transition from traditional production processes to a systemic approach in consideration of the circular economy. This could leverage the efficient use of regenerated wool, the reduction (or lack) of waste production, and the management of the end-of-life of the product.

Sustainable collection development towards greener future: Earthsavers

Nowadays, environmental awareness is more important not to damage the living environment. Sources of the Earth have been decreasing day by day due to many natural and human-induced reasons such as global warming, waste disposal, urbanization, deforestation, etc. Harm of the textile sector on the environment is high and it needs control and awareness. Raw material production, raw material selection, water usage amount, sustainability of processes, refining of wastes, recycle and reuse strategies of textile companies have a very significant effect on the environment. With this awareness, sustainable fashion is created because customer behaviors affect both design and production. In this view, all ingredients and processes turn to the most sustainable forms as much as possible. While being environmentally friendly, required performances of garments should be met to prepare the required end product. In this study, a sustainable collection whose name is Earthsavers is prepared by using recycled raw materials, natural dyestuffs, etc. Their physical and chemical performances are tested. Results of the collection are suitable for acceptance levels and it shows that a collection can be prepared with minimum harm to the environment with at least the same performances as conventional alternatives.

Metallization of PET fibers in supercritical carbon dioxide and potential applications in the textile sector

The high dissolving power of supercritical carbon dioxide (scCO2) and its toxicological safety are used industrially in many technical areas. These include, above all, extraction processes such as the industrial decaffeination of coffee and the extraction of hops. Here, the range of applications was expanded for textile finishes. Specifically, the process engineering fundamentals were developed for the metallization of polyester fibers from scCO2 using organometallic compounds in order to impart electrical, antibacterial and catalytic properties to the modified textiles. The obtained results can be used for antistatic textiles (clean rooms, electrical shielding), for flexible heating elements (sportswear, wellness), textiles with antibacterial properties (wound dressings, outdoor textiles, sailcloth) or, in the long term, for new types of textiles with catalytic properties (e.g., for chemical industry). In addition, the basic combinability of properties was worked out using the example of dyeing/antibacterial finishing, which further expands the economic potential of this water-free high-pressure technology for the textile sector.

Human resource issues and challenges prevailing in Indian textile & garment industry

The textiles and garment sector is a major source of export earnings, government revenue and employment for India. The sector also contributes significantly to the gross domestic product of Indian economy. Indian textile sector is facing many challenges around the globe, especially post-COVID economic recession and rising cost of production. Therefore, mapping of the human resource requirements and their enhancement to facilitate skilled labour is required for the entire gamut of the textile industry. The shortage of skilled manpower is a major constraint affecting the growth of the Indian textile industry which needs a lot of augmentation and technical and financial assistance from both governments and foreign development partners. To overcome the huge skill gap Integrated Skill Development Scheme has been launched to train workers in various segments - textiles, apparel, handlooms, handicrafts, sericulture, jute etc. and sophisticated HRD strategies for better performance. With the objectives of sustainable HRD and promoting R&D to improve productivity across the entire textiles value chain, the Strategic Plan (2011-16) of the Ministry of Textiles focused on skill promotion of all textile workers and creation of new employment opportunities. Integration of sustainability in HRD has become a new central organizing focus for apparel and textiles higher education. Today’s textile trainees are prospective human resources for textile and apparel industry. Our textile education institutes require producing most efficient, highly competitive, technologically updated, resourceful, creative, environment friendly, skilful managers. The HR engaged in T&G industry must be acquainted with the impact of all of the production, distribution, consumption and disposal activities on physical, social, ethical and economic environment, including total quality management, eco-textiles, waste control, recycling, product life cycle analysis, CSR, labour laws, social welfare and healthy labour practices etc. The challenges like sweatshops, child labour, low wages, unhealthy work environment, lack of social capital for technology adaption, need of quality and creativity led policies rather than increasing the quantity of workforce, lack of academia and industry linkage and many more must be treated appropriately for better development of human resources in textile and garment industry. The proper strategy of curriculum designs and models can play a key role in the textile and apparel industry and institutions for generating better resourceful, eco-efficient, cost-efficient, customer-friendly, ethical and socially responsible human resources and by this means nurturing the fascinating dream of sustainable lifestyle of the people around the globe.

A systematic study of cellulose-reactive anionic dye removal using a sustainable bioadsorbent.

Cellulose-reactive anionic dyes are one of the dominant colorants used in textile finishing. Unfortunately, they also produce large quantities of wastewater that must be treated before discharge, demanding low-cost and sustainable adsorbents that can easily be implemented, especially for developing countries with thriving cotton-based textile sectors. In this study, a high specific surface area (670m2/g) water hyacinth root powder (WHRP) bioadsorbent that is neither carbonized nor activated was prepared to remove cellulose-reactive anionic blue dye from an aqueous solution. The effect of adsorption pH (pH=2-8), adsorbent dose (1g/L-6g/L), dye concentration (50mg/L-500mg/L), adsorbent particle size (50μm-1000μm), mixing speed (100rpm -200rpm), and adsorption temperatures (22°C-60°C) were systematically studied. It was found that the protonation of lignin polyphenols in WHRP at pH=2 was responsible for the observed high (∼99%) adsorptive removal of reactive blue dye. The maximum equilibrium adsorption capacity was 128.8mg/g when 1g/L WHRP and 500mg/L dye concentration were used. In addition, adsorption isotherms, kinetic models, and adsorption thermodynamics were investigated. Increasing adsorbent dose, decreasing adsorbent particle size, increasing mixing speed, and lowering temperature favored the adsorption of reactive dye to WHRP adsorbent. The batch adsorption data were best fitted with both Langmuir and Temkin models, especially at 22°C, while the adsorption kinetic behavior was described best using pseudo-second-order kinetics. Adsorption of cellulose-reactive blue dye to WHRP was spontaneous as characterized by the negative Gibbs energy (-11kJ/mol to -24kJ/mol) and exothermic with negative enthalpy (-13kJ/mol to -23kJ/mol). The overall adsorption process was controlled by more than one mechanism since the intraparticle diffusion was not the only rate-limiting step under our experimental conditions. Taken together, the abundantly available and sustainable WHRP is an efficient adsorbent that could be scaled up for treating cellulose-reactive dye-contaminated water.

Crude oil futures to manage the price risk of textile equities: An empirical evidence from India

The textile sector in India is the oldest manufacturing sector. As the raw materials for this sector are sourced from the petrochemical industries, the earnings of Indian textile companies are dependent on the crude oil price. The crude price in the international market has become more volatile and hence, the equity price of Indian textile companies has become more volatile. This study aims to develop two price risk management strategies for Indian textile equities. Using the vector autoregressive (VAR) model, a price forecast model, further the possibility of cross hedge for textile equities with the help of crude futures is examined using the Granger causality test and Pearson correlation statistics. The results of the study showed that crude futures price in India is one of the price determinants of textile industry stock prices.

Due to rising environmental concerns, green innovation has become a familiar and appealing topic worldwide in recent years. In addition, population growth, globalization, urbanization, and industrialization have given rise to many problems, such as damage to the environment, the economy, and the living conditions of society. This paper aims to evaluate and prioritize aspects of green innovation, taking into account sustainability performance indicators. FUCOM-MARCOS hybrid methods were used. The experimental results of the proposed method showed that management technological innovation (C1) is the most influential part for adopting green practices in the textile industry in Nigeria. The study also showed that greening the supplier (C6) and product technology innovation (C5) are the second and third most important aspects of green innovation. Furthermore, it analyzed the sustainability performance indicators using the MARCOS method. The findings reveal that social performance (SPI-3) was the most sustainable and vital indicator in terms of green innovation practices in the textile sector in Nigeria. Sensitivity analysis was also conducted using five other methods, and the results obtained showed stability in the order of the indicators. 

Integrating LCA and blockchain technology to promote circular fashion – A case study of leather handbags

The textile sector accounts for the fourth-highest usage of primary raw materials and water (after food, housing, and transport), the second-highest usage of land, and the fifth highest Green House Gases (GHG) emissions (EEA, 2017). While Life Cycle Assessment (LCA) has been widely used to assess the environmental impact of fashion, most studies are constrained by the lack of reliable data. Blockchain technology may enable better traceability by making origin and journey more transparent. The potential to integrate LCA and blockchain has been discussed in other sectors, but specific protocols in the fashion sector are largely missing. This study aims to address this by a) exploring the use of LCA to measure the impact reduction potential of circular strategies and b) proposing a protocol for the integration of LCA and BC to accurately assess circular practices. Using leather handbags as a case study, an LCA study is conducted comparing two circular scenarios against a baseline to quantify potential benefits from circular strategies. Subsequently, it builds a blockchain-based LCA framework to unleash circularity opportunities through enhanced traceability and data sharing. Results point to substantial environmental benefits from the circular strategies, for example, circular scenario 2 (reuse markets/second-hand leather bag) was estimated to cause between 34.8% and 53.8% lower impacts while circular scenario 1 (leather alternative) contributed to impact reduction of more than 35% of the impacts in most impact categories (10 out of 18). The results also highlight the contribution of blockchain technology to enable traceability and reliable data for identification of environmental hotspots and accurate quantification of circular potential.

Impact of organizational health-oriented strategies on employees' job performance, perceived medical mistrust as a moderator: A COVID-19 perception-based view.

After experiencing the COVID-19 pandemic, employees' health and well-being become a priority for firms. Organizational health-oriented strategies assist them in coping with health-related crises. Based on the social exchange theory, the present study attempts to determine the role of organizational health-oriented strategies in promoting employees' job performance. This study hypothesized that the organizations' health-oriented strategies positively correlate with employees' job performance. This study also assessed the mediating role of employees' psychological wellbeing and trust and moderating role of perceived medical mistrust. For the empirical examination, data of the present study was gathered from the textile sector in China. This study analyzed data through partial least square structural equation modeling (PLS-SEM). For this purpose, Smart-PLS software was used. The outcomes revealed that organizational health-oriented strategies positively enhance the employees' psychological wellbeing, trust, and job performance. Moreover, the results revealed that employees' psychological wellbeing and trust positively mediate the proposed relationships. This study found that perceived medical mistrust moderates the relationship between employees' psychological wellbeing and job performance. However, the findings revealed that perceived medical mistrust does not moderate the relationship between employees' trust and job performance. In addition, the present study's findings provide insights to the firms about the importance of health-oriented strategies. Moreover, this study's findings also serve the literature by providing important theoretical and practical implications.

Contribution of Patch Tests with Occupational Handled Products in the Diagnosis of Occupational Contact Dermatitis: A 10-year Review.

Introduction Allergic contact dermatitis (ACD) is a common occupational disease. Its diagnosis is essentially based on interrogation and patch tests. However, commercially available batteries are sometimes not appropriate for the working conditions and the handled products, which must then be tested. In Tunisia, no previous study has focused on the contribution of patch tests with handled products in the workplace. The objective of this study is to establish the sociodemographic and occupational profile of the patients benefiting from patch tests with handled products in the workplace to identify the characteristics of these products as well as to evaluate the relevance of their positivity and their contributions in terms of aetiological diagnosis of occupational ACD. Methods This is a retrospective descriptive epidemiological study conducted for a period of 10 years from January 1st, 2006, to December 31, 2015, among patients exercising a professional activity and consulting the Dermato-Allergology Unit of the Occupational Medicine ward of the University Hospital Farhat Hached of Sousse for the exploration of ACD. Results During the study period, 113 patients received patch tests of handled products in the workplace with a prevalence of 7.3% of patch-tested patients during the same period. The mean age was 35.79 ± 9.45 years with a male predominance (sex ratio = 1.35). The most represented activity sectors were the health sector in 30.1% and the textile sector in 21.2%. The majority of patients were professionally active (61.9% of the study population) with an average professional seniority of 10.28 ± 8.49 months. In total, 138 patch tests with handled products were carried out of which 46 tests were positive (33.3%). After the analytical study, variables independently significantly associated with the positivity of patch tests with handled products in the workplace were the male gender and the working in the plastics industry. An occupational disease was declared to the National Health Insurance Fund for 8 patients, i.e., 7.1% of cases. Conclusion Patch tests with handled products in the workplace can provide strong arguments for the professional origin of the ACD.
