Despite the fact that textile waste is almost entirely recyclable, approximately 75% of it ends up in landfills worldwide. This has serious environmental and economic consequences. This review focuses on textile waste statistics, its contribution to pollution and recycling, as well as the benefits, barriers, types, and technologies of textile waste recycling. Textile production and textile waste generation have increased alarmingly as a result of fast fashion, which emphasizes low-cost production, frequent consumption, and short-term use of garments. This industry is distinguished by scarcity of resources, excessive consumption, and the generation of large amounts of waste. The frequency of consumer purchases is increasing, while the life span of clothing is drastically decreasing. Recycling does not occur as expected for a variety of reasons, so the environmental impact and economic losses from this waste grow over time. The textile industry currently contributes about 8% of the global carbon budget and 20% of industrial water pollution. Every year, $500 billion is lost to the system due to unused clothing and a lack of recycling. A paradigm shift is urgently required to implement an effective textile waste recycling system.

In this research, an industrially adaptable method is designed for antibacterial clothing. The essential oils of oregano and lavender were extracted using water vapor distillation, then they were spray-dried to form microcapsules. Comprehensive morphological analysis revealed the round shape of the microcapsules with smooth surfaces. The mean size of the optimum oregano and lavender microcapsules were 5.2 µm and 2.2 µm. The essential oils were detected in the polymeric matrix as peaks of microcapsules’ infrared spectra resembled both oils and polymer. Thermal analyses showed that encapsulation delays the degradation of the essential oil. The microcapsules were applied to six different fabrics used in sports and leisurewear by exhaustion. Scanning electron microscopy images indicated the existence of capsules after 10 washes. The antibacterial properties of cotton fabrics were assessed against Escherichia coli and Staphylococcus aureus in terms of the oil and washings. The developed products can serve as a long-lasting, natural antibacterial alternative to other products on the market.

Cigarette butts are one of the most discarded and littered items in the world, with a total amount of around 5.6 trillion, posing a grave threat to the environment and human health. This research seeks to recover cellulose acetate fibers from used cigarette filters and to evaluate the yarn-making capabilities of these fibers. The cigarette butts were gathered from various locations, and the fibers and coating were separated. The fibers were then treated with hydrogen peroxide and sodium hydroxide to eliminate the burned color and odor. Acetone and distilled water were used to filter and distill the material properly. The color coordinates of the chemically altered fibers, including reflectance value and color strength, were measured afterward. To assess the chemical, thermal, physical, morphological, and mechanical characteristics of the modified cigarette butt filter fiber, atomic absorption spectroscopy, Fourier transform infrared spectrometer (FTIR), thermogravimetric analysis, X-ray diffraction, scanning electron microscopy, and tensile properties were examined. Significant and appealing findings were obtained for the mechanical parameters, particularly the tensile strength of 1.2 gm/den for a single fiber, the fiber density of 1.2 dtex, and the effective length of 25 mm, all of which indicate the fiber’s suitability for yarn production. In addition, FTIR, thermogravimetric analysis, and X-ray diffraction measurements revealed that the cigarette butt filter fiber possessed the same characteristics as commercial cellulose acetate fiber. The preliminary results obtained on the recovered cellulose acetate fiber are encouraging for the application of this recovery material from cigarette butts to create a high-demand and value-added product, such as yarn for garment production.

In delayed-curing and non-iron finishing, the sensitized fabric after low-temperature drying should have good surface planeness before curing at high temperatures, which implies that the finishing agent has not reacted with the cellulose fibers during storage; therefore, a suitable non-iron finishing agent is essential for achieving the above objectives. Meanwhile, there are currently no mature and efficient evaluation methods for the storage stability of sensitized fabrics. In this article, the content of characteristic groups of the sensitized fabrics with different storage conditions was measured. The storage time can be shortened from 30 to 6 days with high-temperature storage (40–60°C). The reaction kinetics equation was established under high-temperature storage; then using this equation to predict the cross-linking degree of sensitized fabrics during long-term storage at low temperature, the storage stability of sensitized fabrics can also be evaluated. The relative error of 2.5% between the predicted value and the measured value of the reaction degree showed the accuracy and effectiveness of the established method. This article provided a basis for the stability evaluation of the sensitized fabric and the selection of the finishing agent, finishing process, and storage conditions for the delayed-curing and non-ironing finishing process.

Down jackets consume a lot of energy and water, and emit greenhouse gases, wastewater and other pollutants during the life cycle. For example, melt spinning polyester fibre production, spinning, weaving, fabric dyeing and finishing are high-energy consumption processes. Down processing, fabric dyeing and finishing are typical water consumption and wastewater pollutant discharge processes. Carbon and water footprints are practical tools for evaluating the environmental impact of a product in its life cycle. This article quantified and evaluated the carbon and water footprints of the life cycle of 100 down jackets – from raw material production to recycling and disposal without transportation activities. The results showed that the carbon footprint of the 100 down jackets production was 2544.1 kgCO2e with recycling. As for the water footprint, it showed that fabric production had a great impact on water eutrophication and water scarcity. The water scarcity footprint of 100 down jackets production was 27.46 m3H2Ot, respectively. The water eutrophication footprint generated by producing 100 down jackets in new industry was 1.91 kgPO43−eq. The comprehensive assessment of carbon footprint and water footprint with the life cycle assessment polygon method indicated that the raw material production phase of down jackets generated a more significant impact on the environment than the use phase. The impact on the environment during the use phase is primarily the environmental load on water resources.

In this study, the fabrication – that is, weaving and softening of linen fabric – was accomplished by on-loom integrated finishing on a handloom using a special attachment. The optimization of the process parameters (finish liquor concentration, temperature and curing time) for these on-loom integrated softening finished fabrics were investigated. The softened linen fabric was studied for their physical properties like softness, drapeability, wickability, water vapour permeability, air permeability, total crease recovery angle, tensile and tear strength against untreated fabric and also compared with similar finished market sample. Furthermore, chemical interaction of the softener with linen fabric and their morphology were studied by the Fourier transform infrared and scanning electron microscopy, respectively. The results showed that as the concentration of the finish liquor increased, the softening effect increased, while wickability decreased after the particular optimum point. It was observed that drapeability, total crease recovery angle, tensile and tear strength were increased till the optimum point with the increase in process parameters. However, water vapour permeability and air permeability were decreased. The Fourier transform infrared and scanning electron microscopy studies clearly proved the presence of softener chemical and a coating of a thin layer on the fabric. The optimum process parameters of concentration of the finish liquor, curing temperature and curing time were found to be 10 g/L, 60°C and 5 min, respectively, for softening of linen fabric using this integrated finishing method.

The influence of stitch length and knit structure on comfort characteristics of moisture management finish microdenier polyester knitted fabrics was determined to identify the suitable stitch length and knit structure. In order to study this effect, microdenier polyester filament yarn of 150 denier containing 108 filaments was taken. The yarn was converted to three knit structures such as single jersey, single airtex, and honeycomb, each containing three different stitch lengths of 2.6, 2.9, and 3.2 mm. The effect of stitch length and knit structure on comfort characteristics of moisture management finish knitted fabrics was significant. It was observed that single jersey fabrics showed quicker sinking times for the wetting test. In the wicking test, the wicking length increased continuously with stitch length for treated fabrics. In transverse wicking test for one drop of water and to reach saturation point, single jersey fabric shows a larger water spreading area. The time taken to reach saturation point is also shorter. In the moisture vapor transfer test for reduction in height and weight of water, single airtex fabrics show higher values. In the air permeability test, the single jersey structure exhibited higher air permeability values. It was observed that the single jersey structure with 2.9-mm stitch length had a superior performance with respect to comfort characteristics.

Travel, as one way to relax oneself, has become the first choice for people to enjoy their body and mind in modern society. However, while facing lots of information, how to help users make better decisions on their next travel goals through their historical interest spots is a direction that needs further research in big data recommendation systems. In this thesis, we proposed the deep convolution and multi-head self-attention position network model. First, it extracts the user’s historical interest point feature information by convolutional neural network method, and then performs horizontal and vertical filtering. Next, it interacts the obtained information with the candidate attraction information, and extracts the location information of the historical interest sequence by the multi-head self-attention mechanism. Finally, the model does the attention mechanism of the candidate attraction by fusing the feature information of the location information. The final model achieves a deep fusion of user sequence interest and location feature information. We conducted detailed comparison experiments with the very popular models in the industry on different public datasets, and the results showed that our deep convolution and multi-head self-attention position network model has good performance.

Lifestyle changes have altered the consumption behavior of people. As one of the most energy-intensive and energy-consuming activities in the apparel consumption process, laundry and clothes drying have a significant impact on the environment in terms of carbon emissions and water consumption. Undergraduates are a special category of people whose worldviews are in the developmental stage, and it is important to study and develop their beliefs and behaviors regarding environmental consumption. This study investigates and evaluates the relationship between undergraduates’ consumption behaviors and environmental impacts. The 125 undergraduates in Hangzhou, China are classified into three different washing modes: H-mode (hand-washing only), M-mode (machine-washing only), and HM-mode (hand- and machine-washing) on the basis of their washing behavior. The environmental impacts including water footprint and carbon footprint of undergraduates are calculated by the methods of direct consumptive carbon footprint ( CC F dir ) and direct consumptive water footprint ( CW F dir ). The results show that the factors leading to the environmental impacts of Hangzhou undergraduates’ apparel consumption behavior are: washing frequency, consumer knowledge, washing method, drying frequency and method and clothing purchase quantity. It also reveals that higher washing and drying frequencies can lead to more energy and water consumption, which ultimately result in more severe environmental impact. Besides, consumer knowledge, washing and drying method do have a significant influence on undergraduates’ CC F dir and CW F dir . Understanding the factors that influence undergraduates’ apparel consumption behavior can help cultivate their environmental awareness as well as provide guidance to the government and universities in identifying the environmental impact of undergraduates’ clothing consumption.
生活方式的改变改变了人们的消费行为。洗衣和烘干是服装消费过程中最耗能、最耗能的活动之一，对环境的碳排放和水消耗影响显著。大学生是一个特殊的群体，他们的世界观正处于发展阶段，研究和培养他们对环境消费的信念和行为具有重要意义。本研究对大学生消费行为与环境影响的关系进行了调查和评价。根据中国杭州125名大学生的洗涤行为，将其分为三种不同的洗涤模式:h模式(仅手洗)、m模式(仅机洗)和hm模式(手洗机洗)。采用直接消费碳足迹(CC F dir)和直接消费水足迹(CW F dir)方法计算大学生的环境影响，包括水足迹和碳足迹。结果表明，影响杭州大学生服装消费行为环境影响的因素为:洗涤频次、消费者知识、洗涤方式、烘干频率和方式、服装购买数量。研究还表明，更高的洗涤和干燥频率会导致更多的能源和水消耗，最终导致更严重的环境影响。此外，消费者知识、洗涤干燥方式对大学生的CC F指数和CW F指数有显著影响。了解大学生服装消费行为的影响因素，有助于培养大学生的环保意识，并为政府和高校识别大学生服装消费对环境的影响提供指导。

The 125 undergraduates in Hangzhou, China are classified into three different washing modes: H-mode (hand-washing only), M-mode (machine-washing only), and HM-mode (hand- and machine-washing) on the basis of their washing behavior. The environmental impacts including water footprint and carbon footprint of undergraduates are calculated by the methods of direct consumptive carbon footprint ( CC F dir ) and direct consumptive water footprint ( CW F dir ). The results show that the factors leading to the environmental impacts of Hangzhou undergraduates’ apparel consumption behavior are: washing frequency, consumer knowledge, washing method, drying frequency and method and clothing purchase quantity. It also reveals that higher washing and drying frequencies can lead to more energy and water consumption, which ultimately result in more severe environmental impact. Besides, consumer knowledge, washing and drying method do have a significant influence on undergraduates’ CC F dir and CW F dir . Understanding the factors that influence undergraduates’ apparel consumption behavior can help cultivate their environmental awareness as well as provide guidance to the government and universities in identifying the environmental impact of undergraduates’ clothing consumption.","PeriodicalId":6955,"journal":{"name":"AATCC Journal of Research","volume":"10 1","pages":"241 - 249"},"PeriodicalIF":0.7,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43620150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cotton fabric samples were treated with copper acetate mordant, in addition to green synthesized copper nanoparticles extracted from the Conocarpus erectus leaves, with two different concentrations of 10% and 20%, respectively. Two dyeing techniques, continuous dyeing and exhaust dyeing, were employed. X-ray diffraction confirmed the synthesis of copper nanoparticles with an approximate size of 30 nm. Scanning electron microscopy showed copper nanocrystals with a size range of 30–70 nm. The tensile strength showed an approximately 60% rise in the warp direction and an approximately 20% rise in the weft direction for both continuous and exhaust dyeing techniques. The color strength (ratio of absorption co-efficient (K) and scattering coefficient (S); K/S) showed an improvement of 100% and 20% for the exhaust and continuous dyeing techniques, respectively. Both the dyeing techniques showed a rising trend in color fastness to wash and color fastness to rubbing with an increment up to grade 5. The light fastness showed an improvement up to grade 6 for both the techniques. Fastness to rubbing showed an increment from 1 to 5 for both techniques.
