Design of fluorine-free superhydrophobic silk fabrics with mechanical durability and self-cleaning properties for oil-water separation

The separation of oil and water can be effectively addressed through the application of superhydrophobic coatings. This method, known for enhancing the self-cleaning, anti-corrosive, and friction-reducing properties of materials, typically employs fluorine reagents to ensure the durability of the coating nanostructure. However, the use of fluorine reagents raises concerns related to health and the environment. We present a straightforward and efficient approach to fabricate a robust, fluorine-free superhydrophobic composite coating. The coating solution, comprised of hydrophobic silica nanoparticles and polydimethylsiloxane (PDMS), is formed through sonication. The resulting superhydrophobic coating is effortlessly applied to silk fabric through immersion and subsequent drying/curing. micrograph confirms the creation of porous micro/nanostructures on the silk fabric's surface. Exceptional superhydrophobicity is demonstrated with a water contact angle (WCA) of 161 °±1.5 ° and a small sliding angle (SA) of 5 °±0.5 °. The coating's firmness, durability, and UV resistance are assessed through 20 cycles of sandpaper friction (load 200 g) and repeated tape peeling tests. Furthermore, the modified silk fabrics exhibit excellent capabilities in oil-water separation. This fluorine-free superhydrophobic coating, characterized by its robustness, environmental friendliness, and ease of manufacture, holds promising applications in the textile industry.

Analysis of Research and Development in the Textile and Footwear Industry

Introduction. Rethinking the operational models of textile and footwear industry companies, transforming their organisational structures and marketing strategies, necessitates research and development to create new samples and materials that are most demanded in the new conditions. Methods. The research concept is based on the axiomatic method and system-logical analysis, the method of formalising the model of modern directions of research and development in the textile and footwear industry, the method of summarising results, the method of comparative analysis in processing economic information, and the hypothetical method of the necessity of digital design of new products using the "House of Quality" approach. Results and Discussion. Current research and development in the textile and footwear industry are directed towards creating new goods (samples, products), new technologies and equipment, and new types of production raw materials. In the textile and footwear industry, automation and digitalisation stand out as key tools for research and development, enhancing the efficiency of design and production processes, particularly for custom orders and small-scale production. Conclusion. Despite the advent of numerous innovations in textile materials, fibers, garments, and footwear, the level of research and development activities in specific companies is inadequate, which poses a significant threat to the economic security and the ability to meet societal needs for industry products. The proposed resulting indicator for research and development is the innovation saturation coefficient, which measures the efficiency of research and development expenditures. To enhance the effectiveness of the project phase in research and development within the textile and footwear industry, it is suggested to use the "House of Quality" tool.

Причины стачечного движения на текстильных предприятиях Владимирской губернии в 1905–1907 годах

The article is devoted to the study of the reasons of the strike movement of textile workers in the Vladimir province in 1905-1907. This period of time was marked by the first Russian revolution, which determined the development of Russian history in the next few decades. During the two years revolutionary ideas were popularized in the working environment, making workers to join parties and seek their rights by means of struggle, which resulted in numerous strikes in all regions of the Russian Empire. This phenomenon hasn’t spared the Vladimir province, in particular, a large proportion of the strike movement falls on workers in the textile industry. This is due to the fact that this industry took the first place in terms of the number of enterprises in the province. Each of these enterprises had its own characteristics and problems, which, one way or another, could be the reasons of the strike movement among textile workers. Both general reasons that are characteristic of all enterprises, as well as specific ones that could only occur at individual enter-prises in the textile industry are considered in detail. The methods of synthesis and analysis were used as a research method in order to establish the relationship of all the causes of the strike movement among textile workers in the Vladimir province. It was revealed that the foundation for the emergence of all strikes was the difficult socio-economic situation in which not only the Vladimir province, but the whole country was then located.

Influence of heat treatment and water absorption on mechanical properties of cotton-glass fiber reinforced epoxy hybrid composites: An eco-friendly approach for industrial materials

The effect of the heat treatment and the water absorption of the glass-fiber and recycled cotton fabric-reinforced hybrid composites on the mechanical and physical characteristics were examined in the research. The heat treatment at 80 °C significantly improved G-C-G's tensile as well as flexural strengths by 21% and 28%, respectively. However, due to the improved bonding among the matrix and fiber, G-C-G layer fiber hybrid composites performed better mechanical characteristics than the other alternative composite layers. However, after water absorption, the tensile, and flexural strength of all types of composites diminished from the as-cast samples. In this instance, the flexural and tensile strengths of the G-C-G hybrid composites decreased by 12.87% and 19.11%, respectively, and the bonding between the fiber and matrix degraded was evaluated by SEM images. The maximum amount of water absorption (23.15%) is found for C–C–C composites due to the porosity presented in the cotton fiber. The study evaluated optimal ratios of glass fiber to cotton-reinforced composites, considering both practical and financial aspects. In this case, the G-G-G composites always show better mechanical properties, but the variation among the strength of G-G-G as well as G-C-G is marginal. G-C-G fiber-based hybrid materials are more acceptable because of their affordable cost as well as biodegradable properties than G-G-G composites. Cotton/glass fiber reinforced composites have been proposed as an alternative to appealing elements in the building, automotive, and textile industries.

A novel composite (BiVO4/TiS2) presenting an excellent Z-scheme photocatalytic degradation for Rhodamine B dye under the visible light irradiation

Dye pollutant in the water is the most challenging problem in the textile industries. Novel composites photo-catalysts (BiVO4/TiS2@3%, BiVO4/TiS2@6%, and BiVO4/TiS2@9%) have been prepared to solve this problem. These composites proved promising materials as they have high photocatalytic performance and excellent electro-conductivity properties. Novel BiVO4/TiS2@3%, BiVO4/TiS2@6%, and BiVO4/TiS2@9% composites nanomaterials characterized by Photoluminescence Spectroscopy, UV–visible Diffuse Reflectance Spectroscopy (DRS), Raman Spectroscopy, Energy dispersive X-ray Spectroscopy, Scanning Electron Microscopy, Transmission Electron Microscopy, Fourier Transform Infrared Spectroscopy (FTIR), and X-ray Diffraction Techniques. BiVO4/TiS2@6% shows superior photocatalytic activity and removed RhB molecules (97%) in a very short time of 70 min when irradiated underneath visible light. Compared to pure BiVO4 and TiS2, the average photocatalytic efficiency of composite materials (BiVO4/TiS2@3%, BiVO4/TiS2@6%, and BiVO4/TiS2@9%) was high. Photo generated carrier's transmission becomes smooth due to the very small resistance of BiVO4/TiS2@3%, BiVO4/TiS2@6%, and BiVO4/TiS2@9%. The photoluminescence spectrum (PL) shows that photo-generated carriers of BiVO4/TiS2@6% have the highest separation efficiency. Focusing on a capturing experiment for the degradation of RhB, a good photocatalytic process was presented. It was unexpected to see how quickly the rate of degradation of a new BiVO4/TiS2@6% composite photocatalytic material could still be up to 90% after six cycles. Finally, proposed an excellent photo-catalyst BiVO4/TiS2@6% for wastewater treatment on an industrial scale.

Organisation of the production of shells, mines and cotton pulp at the enterprises of the people’s commissariat of the textile industry of the USSR in the first half of 1943

This article examines the organisation of the production of shells, mines and parts for them, as well as cotton pulp at the enterprises of the People’s Commissariat of the Textile Industry of the USSR in the first half of 1943. Importance and attention is paid to solving the issues of providing them with metal, fuel, electricity, chemicals and other materials. The enterprises were required not only to produce, but also to fully ship the specified products to the equipment factories. Thanks to well-coordinated management and production cooperation, despite numerous problems, most of the factories and factories of the People’s Commissariat not only steadily fulfilled, but also significantly exceeded production tasks. The article presents the monthly dynamics of the implementation of the ammunition production plan, which was generally positive. Its receipt became possible as a result of the analysis of the orders of the People’s Commissariat stored in the fund No. 1689 of the State Archive of Ivanovo Region, introduced into scientific circulation for the first time. Examined in chronological order, they allow us to get an idea of the growing needs of the acting army in ammunition and gunpowder during and in anticipation of the key battles of the East Front of World War II. Categorical demands from the People’s Commissariat to the heads of the main departments and directors of enterprises about the need for unconditional fulfillment of the established plans complement it emotionally. The article is addressed to specialists in the field of the history of the Soviet textile industry, graduates, masters and undergraduates of higher educational institutions.

Indigo dyes: Toxicity, teratogenicity, and genotoxicity studies in zebrafish embryos

Wastewater released by textile dyeing industries is a major source of pollution. Untreated wastewater released from indigo dyeing operations affects aquatic ecosystems and threatens their biodiversity. We have assessed the toxicity of natural and synthetic indigo dye in zebrafish embryos, using the endpoints of teratogenicity, genotoxicity, and histopathology. The zebrafish embryo toxicity test (ZFET) was conducted, exposing embryos to ten concentrations of natural and synthetic indigo dyes; the 96-hour LC50 values were approximately 350 and 300 mg/L, respectively. Both dyes were teratogenic, causing egg coagulation, tail detachment, yolk sac edema, pericardial edema, and tail bend, with no significant difference in effects between the natural and synthetic dyes. Both dyes were genotoxic (using comet assay for DNA damage). Real-time RT-PCR studies showed upregulation of the DNA-repair genes FEN1 and ERCC1. Severe histological changes were seen in zebrafish larvae following exposure to the dyes. Our results show that indigo dyes may be teratogenic and genotoxic to aquatic organisms, underscoring the need for development of sustainable practices and policies for mitigating the environmental impacts of textile dyeing.

Valorization of sugarcane bagasse for high-yield production of laccase through Aspergillus terreus for effective azo dye decolourization

Synthetic dyes such as azo dyes are significant pollutants in the wastewater released from various textile industries. The low biodegradability and production from synthetic sources with high shelf life make azo dyes a challenging material for degradation. This study used chemically mutated Aspergillus terrus in the laccase production under solid-state fermentation using sugarcane bagasse. Initially, the wild-type strain produced a laccase activity of 4.12 U/mL. Later, the alkaline pretreatment of sugarcane bagasse showed a significant increase in laccase activity by 38.9%. Further, random mutagenesis treatment with 100 mM EMS generated a hyper laccase-producing strain with a 2.3-fold increment in laccase activity compared to the wild-type strain. The enzyme displayed optimal activity at pH 6.5 and 35 °C. The metal ions such as Fe3+ (29.4 U/mL), Fe2+ (20.8 U/mL) and Cu2+ (18.05 U/mL) showed positive effects on laccase activity. The crude laccase was used to bioremediate Congo red, a prominent azo dye used in textile and pharmaceutical industries. The preliminary studies with a crude enzyme displayed 68.86% dye decolourization after 24 h of incubation. Additionally, with Taguchi orthogonal array optimization experiments, the maximal dye decolorization of 78.24% was achieved by maintaining crude enzyme concentration (20 U), dye concentration (25 mg/L) and pH 4.5.

Impact of research and development expenses on the profitability of assets: The case of textile and clothing industry in Portugal

The study aims to examine the financial efficiency of the textile and clothing industries in Portugal using official statistical data. The main objective is to assess the relationship between spending on research and development and return on assets. The study analyzes the performance of various subsectors of the textile and clothing industries, presenting the relationship between investments in research and development and the operating return on assets over various economic periods. The study adopted data envelopment analysis, classifying decision-making units based on average efficiency levels. The results highlight sectors of manufacture of textiles for technical and industrial use, manufacture of other textiles, production of outerwear, and manufacture of workwear as the most efficient. In contrast, sectors of manufacture of clothing and accessories, manufacture of knitwear, and leather clothing show lower levels of efficiency. From 2003 to 2022, the textile industry exhibited the highest levels of financial efficiency, with an above-average ratio between spending on research and development and return on assets. However, sectors of knitwear manufacturing and textile finishing have maintained a more or less constant level of financial efficiency. The analysis highlights the need for targeted interventions to increase the financial efficiency of different subsectors within the textile and clothing industries. It is evident that there are varying levels of financial efficiency across these sectors, and the need for benchmarking periods can help identify areas for improvement and set achievable goals.

Water Quality Modelling with Industrial and Domestic Point Source Pollution : a Study Case of Cikakembang River, Majalaya District

Rapid industrial development is one of the leading causes of environmental degradation. The textile industries and the domestic activities in Majalaya District produce wastewater directly discharged into the Cikakembang River. As a result, the Cikakembang River’s water quality has decreased to the point that the water quality cannot be used for daily needs. This study modeled three main parameters in water quality modelling, namely Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), and Chemical Oxygen Demand (COD). Using MATLAB, the three-water quality governing equations originating from the Advection-Dispersion Equation were solved using the Runge Kutte-4 discretization scheme. The numerical modelling was carried out along 2.36 km of the Cikakembang River. All water quality coefficients, such as the DO Saturation (DOsat), the Reaeration Rate (ka), the Dispersion Coefficient (D), the Deoxygenation Rate (kd), and the Decomposition Rate (kc), for the Cikakembang River were estimated using equations developed by existing studies. The estimation of ka and D coefficients requires hydraulic parameters, which in this study were estimated using the HEC-RAS simulation. Meanwhile, kd and kc values were obtained from the calibration and verification process. The Relative Root Mean Square Error (RRMSE) objective function was used to evaluate the results of water quality modelling at three sampling points. In the calibration process, the resultsof water quality modelling produced RRMSE values for the DO, BOD, and COD parameters of 1.99%, 0.36% and 0.92%, respectively. Meanwhile, for the verification process, the RRMSE values for the DO, BOD, and COD parameters are 1.95%, 1.02% and 1.86%. All water quality parameters produce small RRMSE values in the calibration and verification processes. Hence, the water quality model created has good accuracy and stability.

A new strategy for structural color fabrics: Transfer of photonic crystal coatings from slides to fabrics

The construction of three-dimensional photonic crystals on textile surfaces has emerged as a highly effective method to create fabrics with structural color, generating significant interest among researchers. However, the strict requirements of the substrate fabrics and the challenges associated with patterning coatings for bright structural colors have hindered the widespread application of photonic crystal materials in the textile industry. In this study, we present a strategy for obtaining patterned structural color coatings on fabrics made of different materials. Pre-crystallized poly(styrene-methyl methacrylate-acrylic acid) (P(St-MMA-AA)) liquid photonic crystals (LPCs) are used as raw material for the rapid preparation of solid photonic crystals (SPCs). These SPCs with structural colors are used as templates and transferred to various fabrics through transfer printing techniques. Importantly, the SPCs maintain an ordered face-centered cubic structure both before and after transfer. Such a feature ensures that the processed structural color fabrics exhibit vibrant and iridescent structural colors. This result is achieved by modification of the substrate fabric with viscous polymer and the intact retention of SPCs. The sandwich structure formed by the adhesive polymer on the base fabric and the encapsulation of the film-forming material on the SPCs imparts good stability to the structural color fabric. It is worth noting that patterned photonic crystal coatings can be easily obtained on the fabrics made of different materials (cotton, linen, wool, and silk fabrics) by manipulating the shape of the viscous polymer. Additionally, a wide range of common materials, such as paper, wood, steel, and others, can be used as target substrates. This novel dyeing strategy not only offers new ideas for preparing patterned structural color fabrics but also further promotes the application of photonic crystal materials in textile printing or display.

Exploring indigenous fungal isolates for efficient dye degradation: A comprehensive study on sustainable bioremediation in the total environment

Synthetic dyes used in textile industries are hazardous and toxic to the environment, as some of the dyes used in these industries are non-biodegradable. Sustainable technologies using microbes are an eco-friendly and economical approach. Fungal decolorization processes are gaining much importance as biomass absorbs enzymes used in biodegradation. In the current study, six samples of dye wastewater were collected from different industries in the Faisalabad industrial area in Pakistan. The physiological characteristics of these samples were analyzed, and various parameters, including pH, temperature, BOD, COD, and electric conductivity, were investigated. Among six different (sample A-F) wastewater samples, the maximum reduction in BOD was observed in sample E, i.e.,1.3.In contrast, the maximum reduction in COD of sample C, i.e., 30, was observed. These samples' hydrogen ion concentration (pH) was mainly in an alkaline ratio, and a maximum electric conductivity of 8810 µS/cm of sample A was observed. In contrast, a minimum sample E (540 mg/L) was observed. Three indigenous fungal strains were screened and purified from dye wastewater for detoxification of dyes and were identified morphologically and on a molecular basis as Aspergillus iranicus, Penicillium crustosum, and Aspergillus terreus. A comparative analysis of two methods, the tube overlay method and the liquid medium method, were conducted to biodetoxification synthetic dyes, including malachite green, methylene blue, and nigrosine. Spectrophotometric analysis showed that indigenous fungal strains, i.e., Penicillium crustosum decolorizing methylene blue at about 93%, followed by Aspergillus iranicus decolorizing malachite green at about 80% and Aspergillus terreus decolorizing about 90% of malachite green have good potential for degradation of dyes. These strains can be a potential source for treating textile dye effluent.

Objective: This paper investigated the incidence of COVID-19 contraction, signs and symptoms, treatment, pandemic-related anxiety, and related factors in factory workers.
 Methods: This was a descriptive study conducted in a factory operating in the textile industry. No sampling was performed. The sample consisted of 287 volunteers. Data were collected using a sociodemographic characteristics questionnaire and the Coronavirus Anxiety Scale Short Form.
 Results: Less than half the participants tested positive for COVID-19 (41.1%). They were treated at home (68.6%) or in a hospital (19.5%). The most common symptoms were fatigue, joint pain, change in the sense of taste, and headache. The mean duration of home and hospital treatment was 7.00±0.00 and 12.49±6.14, respectively. Participants had a mean anxiety scale score of 7.65±3.71. Less than half the
 participants (31%) had high COVID-19 anxiety levels. The incidence of COVID-19 infection and anxiety was higher in participants who were on medication for chronic illnesses. Age and BMI were correlated with hospitalization for COVID-19.
 Conclusions: The incidence of COVID-19 infection is high among factory workers. Therefore, authorities should consider them a priority group for vaccination and provide them with training on COVID-19 risk factors and preventive measures.

THE STATE OF PLAY: SYMBIOTIC CULTURE OF BACTERIA AND YEASTS (SCOBY) IN TEXTILE INDUSTRY

The fermentation of Kombucha tea produces SCOBY, or Symbiotic Culture of Bacteria and Yeast, as a result of the interaction between bacteria and yeast. In order to fully explore the potential of employing this cellulose as a viable raw material in many applications of industry, numerous studies on the Kombucha SCOBY are now being done. According to studies, Zygosaccharomyces and Acetobacter xylinum are the most frequent bacteria found throughout the SCOBY fermentation process. At the air-liquid interface, these microorganisms help produce cellulose fibrils extracellularly, resulting in a biofilm. An overview of the favourable conditions for SCOBY manufacture is provided in more specific, as well as the aspects that may influence the product, and its suitability for textile and fashion sector applications is appraised. The advantages of this biofilm are being explored, including in several industries especially in textile and fashion industry. The microbial consortium's tea fermentation process was able to demonstrate an increase in specific biological activities that had previously been researched. However, there are some limitations in the applications of SCOBY in the textile that need to be highlighted. Thus, this review focuses on the SCOBY properties, challenges and potential available to make it feasible in textile industries.

Tapered optical fiber sensor coated with carbon nanotubes containing functional groups or Fe nanoparticles for sensing applications

Anthraquinone dyes are the second largest group of synthetic dyes that are widely used for dyeing textiles. As an anthraquinone dye, Alizarin Red S (ARS) has been widely used in the textile industry; however, it is extremely resistant to standard degradation due to its structural peculiarities and it can cause a serious threat to aquatic ecosystems and human health. Previous studies on theoretical calculations of single-wall carbon nanotubes (SWCNTs) and multi-wall carbon nanotubes (MWCNTs) demonstrated that SWCNTs and MWCNTs can serve as adsorbents, with their highly active sites and large specific surface area, and they exhibit great performance. In the present work, the detection of ARS by the SMF28e single-mode fiber optic-based sensor was investigated. For detection of ARS, multiwall carbon nanotubes with -COOH and -OH functional groups and Fe nanoparticles were applied on the optical fiber. The effects of contact time, adsorbent dose, pH and temperature on the adsorption were studied. The study evaluated the feasibility of detecting and removing ARS from aqueous solutions using MWCNTs with the -COOH and -OH functional groups and Fe nanoparticles.

Optimizing manufacturing firm performance in Indonesia through strategic orientation and servitization

This study aims to investigate factors influencing servitization and firm performance within Indonesian national manufacturing companies, focusing on export-oriented entities such as automotive, electronics, textile, and food processing industries. Strategic orientations – market, technology, service, and learning – are investigated as key dimensions guiding firms’ strategic decisions amidst dynamic business environments. A comprehensive survey involving 100 companies representing a diverse spectrum of the Indonesian manufacturing sector is conducted. These companies encompass a range of statuses, including joint ventures (12%), multinational companies (2%), and national companies (86%). Through a purposive sampling strategy, representation across different company types is ensured to capture the breadth of perspectives within the industry. The quantitative approach involves surveying managers across various organizational levels, including top-level executives, middle managers, and front-line supervisors. Input from different managerial tiers is solicited to understand strategic orientations and their impact on firm performance. Data analysis, employing validation, descriptive statistics in MS Excel, and inferential statistics using Smart PLS yields significant insights. Market, service, and learning orientations emerge as influential factors in both basic and advanced services (p < 0.05), while technology orientation lacks statistical significance. Notably, market orientation significantly impacts advanced services (p < 0.05). Furthermore, the findings underscore the significant influence of service provision on firm performance across both basic and advanced services (p < 0.05). The critical role of strategic orientations, encompassing technology adoption, market positioning, service delivery, and organizational learning, in driving servitization and enhancing firm performance in Indonesian manufacturing is emphasized.

Adsorption and photocatalytic degradation activities of a hybrid magnetic mesoporous composite of α-Fe2O3 nanoparticles embedded with sheets-like MgO

Crystal violet (CV), identified as a potential carcinogen, is a synthetic dye prevalent in wastewater from textile and paint industries. Therefore, the current study demonstrates that the hybrid composite of mesoporous magnetic α-Fe2O3 nanoparticles @ sheet-like MgO (Fe2O3@MgO) can be employed as a potential effective sorbent and photocatalyst for CV-removal from polluted water. A comparative study was systematically performed on the CV-removal using MgO and Fe2O3@MgO composite. The physicochemical, textural, and structural properties, morphological features, and elemental composition of mesoporous Fe2O3@MgO composite were intensively investigated. Batch trials were performed to optimize the sorption conditions. The highest CV-uptake efficiency was detected at pH 9 within the adsorption equilibrium time of about 30 min, where the maximum capacity of Fe2O3@MgO was 50.8 mg/g. Under UV irradiation, the Fe2O3@MgO photocatalyst exhibited a high efficiency and fast response toward CV-removal. The mechanism of CV removal was researched through zeta potential (ZP), bandgap, and density functional theory (DFT) calculations. The outcome demonstrated that mesoporous Fe2O3@MgO sorbent/photocatalyst could be recycled and reused ten times, making it a cost-effective solution for removing CV-dye from wastewater. This manuscript suggested that mesoporous Fe2O3@MgO composite is an efficient adsorbent/photocatalyst for fast, affordable, and efficient decontamination of CV-dye from wastewater.
