  • Brazilian Cotton Jeans Recycling: Characterization of Shredded
           Pre-consumer Waste

    • Free pre-print version: Loading...

      Abstract: Abstract Brazil is the second largest producer of jeans in the world and most of the 100% cotton denim (jeans fabric). The most produced and consumed denim is characterized as lightweight (or under 12 OZ). The 12 OZ denim characteristics are: 400 g/m2 (12 oz/yd2) weight, 3 × 1 twill weave, 90 Tex (6.5 Ne) warp yarn count number and 65.6 Tex (9 Ne) weft yarn count number. For 100% cotton denim, specifically in the pre-consumption process, the waste generation comes from the cutting step, reaching almost 16% of the employed fabric in the production of jeans pants. After shredding, the defibrate textile material is constituted by cotton fibers and yarns’ segments. The present study aimed to investigate issues on recycling of pre-consumer jeans in Brazil; the determination of the yarn count number of weft and warp yarns present in shredded pre-consumer jeans fabric waste (100% cotton, from 10 to 11 OZ, 2 × 1 and 3 × 1 twill, open-end yarns); and the estimative of losses concerning the original waste material. A systematic review of the scientific literature and experimental determinations were carried out for the weft and warp of the shredded jeans material determining the count number, length, and thickness of the yarns. In the analyzed material from mechanical recycling, it was found that the yarns’ segments were thinner compared to the original ones, warp yarns lost near 62% of their original material after shredding, while the weft yarns lost near 53%. Furthermore, a fraction of the original waste material cannot be reinserted in a conventional textile process, but it is still possible to use it in other types of products, such as composites. It is concluded that the feasibility of reinserting recycled must be preceded by other characterization studies to be used correctly in industrial or artisanal processes, enabling the production of recycled articles with reproducibility of its characteristics, thus ensuring reintegration and maintenance in the market.

  • Cotton Weaving Waste Incorporation in PVC Composites

    • Free pre-print version: Loading...

      Abstract: Abstract The largest amount of solid waste from the textile industries is mainly derived from fabric manufacturing until the cutting stage: hard fibers (spinning waste), beaming and soft fibers (weaving yarn waste), and off-cuts (cutting process). This research aimed to (i) conduct an exploratory interview with a large Brazilian cotton textile manufacturer to identify its main solid waste and corresponding destinations; and (ii) produce and evaluate PVC composites reinforced with cotton textile residues from the weaving process. Cotton fibrous reinforcements in the proportion of 2.5% (w/w) presented the best results of tensile strength and elongation concerning the others. Briquette residue (2.5%) had better dispersion in the matrix and slightly higher tensile strength when compared to other residues. The composites presented different visual aspects, and their use in fashion products with sustainable appeal could be a viable alternative. Therefore, additional tests should be performed to ensure the appropriate mechanical properties for applications in this and other areas.

  • The Characterization of the Date Palm Tree Leaflet for Using That as Green
           Materials for Building House

    • Free pre-print version: Loading...

      Abstract: Abstract The objective of this work is to exploit the residue of the date palm leaflets of the Biskra region which is found in large quantities for the purpose of recovering it and using it as reinforcement in building materials and/or re-construction of house in the area. The characterization of the date palm leaflets (DPL) aims to better understand these components and better use it in its ideal position. The present study examined the physical and chemical properties obtained using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM) . Three types of Deglet Noors from different regions (Mekhadma, Bouchagroune and Lichana) are used as study samples named DN1, DN2 and DN3, respectively. The results of the XRD analysis show that the crystalline levels are respectively DN1 (42.9%), DN2 (62.12%) and DN3 (62.83%). Note that the crystallite size results show that the change in region of collected DPL changed its size dimensions as follows: DN1 (2035.9 nm), DN2 (2026.6 nm) and DN3 (2035.9 nm), respectively. The FTIR test showed the presence of cellulose, hemicelluloses and lignin in the three samples. The SEM images show that our samples are a mixture between fiber and particles with different diameters and lengths. Diameters are between 10 and 50 μm and lengths between 100 and 300 μm.

  • Natural Fibre Composites Manufacture using Wrapped Hemp Roving with PA11

    • Free pre-print version: Loading...

      Abstract: Abstract Hybrid yarn of reinforcement and thermo-plastic fibres gives the composite manufacturing process the advantage to dispense resin transferring task. The objective of this study is to make a hybrid yarn based on hemp and polyamide 11 (PA11) fibre for composite application. The weaveability of the manufactured hybrid yarn will be checked, and the tensile and flexural properties of the manufactured composite will be evaluated. The hybrid yarn is produced using the wrapping technique where a multifilament of polyamide 11 is wrapped around a low-twisted hemp roving. This wrapped yarn is woven; then, a composite plate is produced by the thermo-compression process. Textile and mechanical properties are characterised at each production scale: yarn, fabric and composite. Results from textiles and mechanical characterisation depend on several related parameters according to each scale, to the wrapping process and weaving process as well as to the manufacturing process of composite. At composite scale, the hemp content of these composites in volume is around 45%. The tensile strength of the produced composite from Hemp/PA11 reached 64 MPa, which is 18% higher than that of hemp/PA12 composite produced in the previous study (Corbin et al. 2020b).

  • Energy consumption, environmental impact, and implementation of renewable
           energy resources in global textile industries: an overview towards
           circularity and sustainability

    • Free pre-print version: Loading...

      Abstract: Abstract This study aims to review the energy consumption, environmental impact, and implementation of renewable energy in textile industries to enhance circularity and sustainability in the textile industry. Textiles and clothing are the fundamental needs of human beings; this sector consumes an abundant amount of fossil fuels as the main energy supply and has impacts on the environment. However, alternative clean sources of energy can be applied in the textile industry. Moreover, the gradual elimination of fossil fuels and the implementation of renewable energy resources in textile industries is essential. By this paper, fossil energy usage in textile industries and its impact, as well as the application of alternative energy in textiles, can be perceived. In this study, the background of the textile industry, energy consumption, environmental impact, alternative sources, and saving of fossil energy has been narrated tidily. In summary, generally, more than 50% of thermal energy and around 70% of electricity are used in various processes of the textile industry. Along with fossil fuels, it has some adverse effects on the environment. But alternative energy sources and improved energy efficiency can reduce this pollution. Nevertheless, currently, textile industries consume plenty of fossil fuel energy to produce end products; there are huge opportunities to implement renewable energy as well as applying BAT and advanced technology can also increase the existing energy efficiency in the textile industries. Since textile is the eternal demand of human beings, we must give extra effort to this sector and save the immediate vicinity of mankind as well.

  • Mechanical Characterization of Home Compostable Biopolymer Composites
           Reinforced with Organic and Inorganic Residues for Single-Use Plastics

    • Free pre-print version: Loading...

      Abstract: Abstract This work features composites developed with home compostable biopolymers reinforced with residues of organic and inorganic origin for use in single-use plastics. The masterbatches were produced in a twin-screw co-rotating extruder combining a home compostable biopolymer reinforced with 2.5, 10, and 20% w/w wood, coconut, slate, and slag residues. The tensile tests showed an improving trend in the Young’s modulus of the masterbatches made with cellulosic fibers, especially wood. In the masterbatch with 20% w/w wood, an increase, of 43%, in Young’s modulus was achieved. In the samples where mineral residues were the reinforcement used, the best results, in terms of Young’s modulus, were obtained for the percentage of 10% w/w. With the highest incorporation of mineral residues, the mechanical properties decreased. Further analysis was carried out with scanning electron microscopy (SEM) tests to evaluate the morphological microstructure of some of the samples produced. The SEM test results show the samples reinforced with wood and coconut fibers created stronger bonds, at the interface, with the polymer matrix than the samples with slag and slate.

  • Environmental Impacts of Polyester-Cotton Blend Compared to Cotton Fiber
           in Brazil

    • Free pre-print version: Loading...

      Abstract: Abstract Polyester in the textile industry is frequently mixed with cotton fibers to produce PET-CO blend fabrics, widely used in clothing and home textiles. However, polyester’s slow degradation (up to 400 years) and the production of cotton and PET are related to environmental impacts. Brazil is prominent in the cotton production scenario due to the quality and volume of its production, although of environmental damages and health issues to farmworkers. Blend fibers, being a junction between natural and synthetic ones, carry the impacts of both productions. This study aimed to compare the environmental impacts of pure cotton and PET-CO (blended polyester and cotton) productions. A bibliographic analysis of literature and reports from sectorial organizations was carried out, resulting in data and knowledge about the environmental impacts caused by textile and clothing production related to cotton and polyester-cotton blend and other actions turned to reduce or nullify these impacts towards the circular economy, with emphasis to textile recycling. The adoption of the circular economy needs to be deeply understood so that the textile waste returns to the beginning of the production cycle, as well as the need to improve the production processes to avoid polluting and losses of energy, water, and other resources through actions, such as the correct separation and disposal of waste.

  • Life Cycle Gap Analysis for Product Circularity and Sustainability—a
           Case Study with Three Different Products

    • Free pre-print version: Loading...

      Abstract: Abstract This paper aims to demonstrate the applicability and benefits of life cycle gap analyses for systematically integrating circular economy considerations into life cycle assessment. It presents life cycle gap analyses for three entirely different products (rechargeable batteries, T-shirts, plastic bottles), compares the applications and results, and draws conclusions on the usefulness of the method. The case studies reveal life cycle gaps of 54% (plastic bottles), 61% (rechargeable batteries), and 98% (T-shirts), indicating high potential for further circularity improvements in the current life cycle systems of different industries and product groups. At the same time, a potential weakness of the method is underlined. Even considering options to increase circularity, life cycle gaps of at least 45% still exist, raising the question of what measures are really needed in order to achieve product circularity and sustainability. The analysis demonstrates the general applicability of life cycle gap analyses and their contribution to the integration of circular decision-making and life cycle thinking.

  • Effects of Dry Etching Plasma Treatments on Natural and Synthetics Fibers:
           a Comparative Study

    • Free pre-print version: Loading...

      Abstract: Abstract Nowadays, natural and synthetic fibers are becoming a valuable resource for composite industry. The use of natural and synthetic fibers as reinforcement of polymeric matrices has many advantages: it betters mechanical properties per unit of weight, decreases the cost of manufacturing per unit of volume and, among other things, it is environmentally friendly. Despite all of this, the low compatibility between the constituents can result in a poor mechanical behavior. However, plasma treatments can modify the surface of the fibers used as reinforcement, so the bond between the phases of the composite can be improved by its use. In this work, we present the results of a comparative study of the effects produced by dry etching plasma treatments on Young’s modulus and surface morphology of Guadua angustifolia, Fique, and Nylon fibers. Natural and synthetic fibers were exposed to physical bombardment with argon ions during different time intervals. Scanning electron microscopy (SEM) analysis showed that all treated fibers exhibited rough surfaces and that the surface roughness augmented by increasing the bombardment time. The results of Young’s modulus as a function of bombardment time displayed a significant increment in Guadua and Fique fibers but did not change significantly in Nylon fibers. The serious damages produced in the natural fibers by ion bombardment as determined by SEM analysis could be considered as the main cause of the observed increase in Young’s modulus. Other causes, however, can not be ruled out as responsible for the increment in Young’s modulus in natural fibers and the almost null effect in synthetic fibers.

  • New Generation of High-Tech Nonwovens Through Nanotechnology

    • Free pre-print version: Loading...

      Abstract: Abstract Felting is a well-known process that allows obtaining a three-dimensional structure in which fibres are randomly dispersed. This type of process includes the steps mechanical agitation, heat, moisture and usually soap. Associating this type of conventional methodologies with nanotechnology is a high potential approach since with this conjugation is possible to obtain felts with specific functionalities that can be applied in very specific areas. In this scientific research, the main objective was to achieve a simplified and low environmental impact process of nanofunctionalization of wool-based felts (sheep and rabbit wool), produced from the conventional felting process. The objective of this functionalization at the nanoscale was to create a new generation of high-tech nonwovens, using zinc (Zn) and silver (Ag) nanoparticles (NPs), to obtain self-cleaning, antistatic and antimicrobial properties. So, different proportions of NPs were studied to obtain the ideal conditions that intensify the pretended functionalities. From the results obtained, Zn NPs presented themselves as the most effective in self-cleaning (5% w/w Zn) and antimicrobial properties (2.5% w/w Zn), whereas Ag nanoparticles in the antistatic behaviour (10% w/w Ag).

  • Brazilian Agro-industrial Wastes as Potential Textile and Other Raw
           Materials: a Sustainable Approach

    • Free pre-print version: Loading...

      Abstract: Abstract The Brazilian agro-industrial chain generates about 291 million/tons/year of wastes, which, if inadequately destinated, could originate social and environmental risks. There is a growing need for the use of alternative raw materials to replace that originated from fossil resources in the Brazilian industry. Renewable materials play an important role on the sustainability of ecosystems and materials’ circularity. The issue has acquired importance in light of recent bio-based agro-fiber development potential applications. Considering sustainability guidelines, this study aimed to analyze the main Brazilian agro-industrial waste crops (temporary and permanent) as important sources of natural fibers and other raw materials. A systematic review of the literature (SRL) about Brazilian researches, based on concepts of industrial ecology, and the creation of a bibliometric analysis network were carried out. The agricultural biomass related to the main crops presents characteristics making them suitable to be applied for textiles, as natural fibers and polymers, in biosorbents for industrial effluents, and cellulose obtention and reinforcement material in composites. Thus, scientific investment in researches on materials and technology development are necessary to provide applications that could meet current and future demands and expand the scope of new materials for sustainability.

  • Cellulosic Fabric-Reinforced Cementitious Matrix (FRCM): Ligaments,
           Treatments, and Employment

    • Free pre-print version: Loading...

      Abstract: Abstract Fabric-reinforced cementitious matrix (FRCM) with synthetic reinforcements has been employed in a wide of precast products in the current market. However, FRCM employing cellulosic fibers has been limited in civil engineering applications due to the absence of a well-established standardization. Cellulosic textile structures present many advantages to strengthen cementitious composites, which depend on the type of natural fiber, forms that are organized (e.g., bundle fibers or twisted yarns), and ligaments. This study aimed to develop an overview of FRCM to identify how cellulosic textile has been designed and processed in research, according to type, shape, properties, durability, and matrix formulations. The main findings were as follows: (i) bundle fibers and low entangled yarns presented potential to increase the tensile properties; (ii) woven canvas prevailed in the cementitious composite applications; (iii) 3 and 4 layers of fabrics presented better mechanical performance than few layer samples; (iv) the alkaline treatment is one of most employment to improve the adherence; (v) to prevent cellulose degradation, resin coatings (epoxy) or pozzolan additions (silica, metakaolin, nanoclay, ashes from agricultural wastes) are employed. Future investigations are necessary to improve cellulosic FRCM; opportunities for study in textile area are proposed: enlargement of fabric technologies, hybrid fibers, machinery technology (3D fabrics, complex knit) adaptation to use cellulosic fibers, and new architectural design for cellulosic FRCM applications (curved forms and sizes).

  • Food Security and Sustainability Through Solar Drying Technologies: a Case
           Study Based on Solar Conduction Dryer

    • Free pre-print version: Loading...

      Abstract: Anthropological activities along with increase in population over several decades engender several global environmental issues including climatic change and food security. According to FAO, the current rates of food insecurity prevalence (9.7%) and the food loss index (13.8%) show an alarming trend which invigorates food industries in working towards food security. Sustainable use of resources has become an issue in each food supply chain segment. Drying technologies are highly energy-intensive and are the most commonly encountered operations in food processing; the stakeholders must address this issue. Furthermore, integrating sustainable drying technologies in the food supply chain will substantially reduce post-harvest losses and leverage inventory management for food products. Sustainability could also be unified by utilizing sustainable raw materials, e.g., plant-based raw materials and millets. The solar conduction dryer is one of the recently developed sustainable technologies for dehydration. The design of this dryer and its variants embodies all three-heat transfer mode, making it one of the most versatile and energy-efficient solar dryers (e.g., 160% more efficient than conventional solar tunnel dryer) and cost-effective dryer (40% lower capital cost than conventional solar tunnel dryer). Under the plank of affordability, availability, and accessibility, such innovations can trigger the hopes for alleviation of poverty, opportunity for decent work, and economic growth and reduce inequality. Ensuring nutritious food in the rural sector of India and other parts of southeast Asia and Africa is critical to the survival of mankind. This paper presents some key outcomes of an in-depth study carried out in recent times various parts of India. Graphical abstract

  • Natural Fibre Insulation Materials: Use of Textile and Agri-food Waste in
           a Circular Economy Perspective

    • Free pre-print version: Loading...

      Abstract: Abstract Fibrous materials are among those most used for the thermal and acoustic insulation of building envelopes and are also suitable for a wide range of applications. In building construction, the demand for products with low environmental impact — in line with the Green Deal challenge of the European Community — is growing, but the building market is still mostly oriented towards traditional products, missing the many opportunities for using waste materials from existing industrial production. The paper presents the experimental results of new thermal and acoustic insulation products for building construction and interior design, based on previous experiences of the research group. They are produced entirely using waste sheep’s wool as a “matrix” and other waste fibres as “fillers”. The materials proposed originate from textile and agri-industrial chains in the Piedmont region and have no uses other than waste-to-heat biomass. The panels have characteristics of rigidity, workability, and thermal conductivity that make them suitable for building envelope insulation.

  • Development of Cotton-Based Compression Stockings for Class II Compression
           Requirements

    • Free pre-print version: Loading...

      Abstract: Abstract This work focuses on the development of class II medical compression stockings having improved tactile properties by the use of cotton components in their construction. Nine compression stockings having at least one cotton constituent yarn and three all nylon stockings as reference samples were produced. Irrespective of both the inlay elastane yarn count and ground yarn properties, the water vapor permeability of the compression stockings was mainly governed by the fiber types employed in the inlay yarns. The compression tests performed were promising since the pressure exerted by the compression stockings having cotton components covered the required pressure range.

  • Micromechanical Tests on Natural Fibre Composites with Enzymatically
           Enhanced Fibre–Matrix Adhesion

    • Free pre-print version: Loading...

      Abstract: Abstract Natural fibre–reinforced composites are more sustainable than other composites with respect to the raw materials. Their properties are attractive due to high specific properties, and especially so wherever high damping is valued. As the interphase between fibre and matrix is the region of highest stresses, a strong bond between fibre and matrix is essential for any composites’ properties. The present study compares two methods of determining the interfacial shear stress in natural fibre–reinforced composites: the single fibre fragmentation test and the single fibre pullout test. The studied composites are flax fibre reinforced epoxy. For a variety of fibre–matrix interaction, the fibres are treated with a laccase enzyme and dopamine, which is known to improve the fibre–matrix shear strength. In the observed samples, single fibre fragmentation test data, i.e. of fracture mode and fragment length, scatter when compared to pullout data. In single fibre pullout tests, the local interfacial shear strength showed a 30% increase in the laccase-treated samples, compared to the control samples. The method also permitted an evaluation of the frictional stress occurring after surface failure.

  • Influence of Fibre Diameter on the Wool-Based Felt Properties

    • Free pre-print version: Loading...

      Abstract: Abstract Felts are nonwovens formed by fibres with a random orientation. The felting process is a bonding process and usually it includes the steps mechanical agitation, heat, moisture and usually soap. Due to its three-dimensional structure, its applicability has been growing in areas such as musical instruments, industrial sound insulation and fashion. The current work aims to study the influence of the fibre diameter in the wool-based felt performance, mainly in terms of air permeability (AP) and mechanical properties, considering a range of felts prepared with blends of wool fibres with distinct diameters — namely 14, 16 and 18 µm. The felted structures were tested for physical characteristics (thickness, aerial mass), morphologically, AP, and tearing and tensile strength, in a comparative analysis to assess the effect of fibre diameter. The results show that the fibre diameter has implications in the structure of the three-dimensional structure. The obtained results showed that fibres with higher diameters have higher AP values, due to the empty spaces among the fibres.

  • Eco Printing of Linen and Tencel Substrates with Onion Skins and Red
           Cabbage

    • Free pre-print version: Loading...

      Abstract: Abstract Printing textiles with plant materials is considered a sustainable practice for the development of unique patterns. This work studied the eco printing technique, using onion skins and red cabbage to create prints on linen and Tencel substrates mordanted with tannin and potassium alum. The chromatic and visual effects of the patterns were analyzed according to the influence of different materials and process variables, namely, the fibers, plant materials, mordants types, and the printing and mordanting processes. The color fastness to lighting, washing, and dry and wet rubbing were also verified on a set of samples. A prototype of a garment was made with the set of variables that presented the best result in the color fastness tests, in order to demonstrate a possible application of an eco printed fabric on a clothing. From this investigation, it was possible to verify the processes that involve the practice of eco printing, as well as to understand the influence of the materials and methods used on the aesthetics of the patterns. In addition, the color fastness tests indicate whether the materials used and the processes carried out are feasible for application in fashion fabrics. This work contributes to designers’ knowledge on the eco printing method, as well as a comprehensive understanding of how the combination of set of materials and process variables interferes in the visual and chromatic effects of the prints. In addition, the development of a research prototype demonstrated the potential of this technique to produce creative and sustainable textile patterns.

  • Mechanical and Thermal Behavior of Recycled Low-Density Polyethylene
           Composites with Coal Mining Waste

    • Free pre-print version: Loading...

      Abstract: Abstract The mining process in a coal industry is responsible for a large environmental impact, 60% of the total extracted are discarded and sent to a controlled dam due to its potential toxicological effect when exposed to the environment. On the other hand, polymer consumption has grown at an annual rate of 5%, exceeding 300 million tons/year. Therefore, the main objective of this work is the preparation of a composite using recycled low-density polyethylene polymer and coal mining waste, aiming to improve mechanical and thermal properties and mitigate the environmental impacts. Composites in fractions between 20 and 80% wt coal mining waste were prepared and characterized. Formulations with up to 60% of coal mining waste showed properties of interest for the development of new materials in civil and architectural construction.

  • Biocomposites from Cotton Denim Waste for Footwear Components

    • Free pre-print version: Loading...

      Abstract: Abstract The materials’ production applied in the footwear industry corresponds to about 80% of the impacts generated in the total useful life of shoes. Cotton denim waste presents great opportunities for recycling. Logistical issues are the main point to industrial waste availability as raw material. This research aimed to describe the case study of denim wastes logistics from a clothes factory at Toritama city, Pernambuco state, Brazil (known as the “city of jeans”), and to develop biocomposites from cotton denim wastes (shredded and powder fibers) for application in the footwear components. A better destination could be provided for all denim wastes generation since it is easy to separate different denim composition wastes in the factory before the collection. However, blended fabrics are a complex issue for denim waste employment. The obtained biocomposite layers could be improved for applications in footwear components, mainly “soft” composites in insoles and “condensed” composites in toe-puffs and other shoe reinforcement components. Denim wastes employed in footwear components could reduce the amounts that end up in landfills and could replace certain petroleum-based components in shoes. Thus, the footwear industry could invest in future research and applications of biocomposites for sustainable manufacturing models.
