Abstract: This study investigated the charging and discharging characteristics of charge-accumulating textile fabrics, especially those made of composite fibers, by measuring the voltage half-life, which is the time required for voltage to decrease to half of maximum value. Results demonstrated that composite textile fabrics exhibit significantly different electrostatic properties compared to conventional textiles such as cotton and polyester. A non-contact electrostatic measurement method was employed using corona discharge to apply positively charged ions to the material. It is shown that this method makes it possible to simultaneously measure the time-dependent surface voltage and charge accumulation during charging processes, as well as the surface voltage decay during the discharging processes.

Abstract: Waste materials (WAS) have recently been recycled into the environment and are materials that come to the fore in terms of both cost and environmental use. The waste material used in this study is a type of material classified as waste in a local textile factory due to the raising process, which cannot be converted back into textile. In this study, the effects of 5%, 10%, 15%, 20%, 25%, 30% and 40% waste raising on the mechanical and physical properties of the composite samples produced by combining them with epoxy were investigated. For comparison purposes, fabric reinforced samples made in previous studies were considered as reference samples. WAS 10 sample is the sample where the tensile strength value reaches its maximum. In the impact test results, the WAS 10 sample absorbed 1.63 times more energy than the WAS5 sample (1.3 J) that came after it, with 2.12 J. The WAS5 sample reached a hardness value of 205.067 in the microhardness test, 3.45% better than the WAS10 sample. Overall, it has been determined that the composite obtained from this waste material, which cannot be recycled into textile products, can be used as an alternative to interior plastics in the automotive industry.

Abstract: In recent years, the textile industry has increased its exports compared to previous years and produces thousands of jobs per year. However, some manufacturing companies in the textile industry experience low efficiency, such as the current textile company under study associated with unplanned machine downtime and idle time. In this sense, this study aims to promote the capacity, productivity, and efficiency of textile companies that manufacture garments. Therefore, a Lean Maintenance model supported by the integration of Lean Manufacturing instruments and techniques such as TPM, 5S, Kaizen is proposed in order to improve machine availability and quality through management metrics. After the implementation of the proposed tool integration, the activities of the operations were standardized, an increase in efficiency was generated, and a favorable change in maintenance metrics was achieved.

Abstract: The COVID-19 pandemic significantly impacted the textile industry's supply chain management leading to unprecedented disruptions in global trade and manufacturing operations. This paper presents an overview of the challenges faced by the textile industry during the pandemic and how supply chain management strategies are being restructured to mitigate risks and ensure business continuity. The pandemic highlighted the need for greater visibility and transparency in supply chains as well as the importance of diversification of suppliers and production facilities. Many new challenges in data quality were also exposed. This paper discusses the implications of these changes for the future of the textile industry and new thinking needed in managing supply chains.

Abstract: This project-based research examined the explorations of the Soekarno-Irian Barat Rupiah banknotes' visual element as textile motifs, which were then produced into a womenswear collection using the digital printing technique. The topic was chosen based on the phenomenon among the society that often sees money only as a payment tool, while actually, it bears more meanings for a nation, including historical, cultural, and political messages, which makes it eligible to be also known as a cultural heritage product that deserves to be preserved. One alternative to preserving the visual elements of a cultural heritage product is through textile and fashion products application. The project started with literature studies and interviews; explorations of motifs, designs, materials, and also style studies; and was completed with fabric and garments production. The considerations behind the aforementioned aspects in the methodology were made through a design thinking framework with mixed-methodological approach which combines qualitative and quantitative data collection and analysis. The intended impact of this practice work is to create a new perspective towards banknotes as a case study for cultural heritage artefacts whose design elements can be preserved through product application in the creative industry, such as textile and fashion products.

Abstract: Abstract: Improving the environmental impact of textile waste is essential for the good functioning of the planet, as it is not viable to prolong the recycling of textile materials indefinitely due to the loss of properties. The presence of dyes in fabrics is a key point to study from the perspective of biodegradability, as the presence of these dyes in effluents is widely studied due to their high polluting impact on water. This project has analysed whether the presence of dyes in fabrics affects their biodegradability process. In addition, it has been studied whether finishing with laccase enzyme, which is usually used to purify the wastewater from the dyes of the indigo blue dye used, influences the degradation of the fabric. For this purpose, dyed and undyed cotton fabrics impregnated with this enzyme were analysed. Following the proposed measurement protocol, it has been defined that fabrics dyed with the indigo blue dye (VAT BLUE I) have a positive influence on degradation, while the presence of small doses of compounds added to the fibres, such as the laccase enzyme studied in this case, can lead to the generation of deviations in the biodegradability of the sample. Although the efficiency and efficacy of this enzyme in dye degradation under anaerobic conditions has been demonstrated, under compost conditions its effectiveness decreases and negatively influences the biodegradability process. No ecotoxicity is shown in soil after the biodegradation process. Keywords: Sustainability; laccase; vat dye; textile; environment; burial.

Abstract: Bio-based textiles are an emerging area of cross-disciplinary research, involving material science and design and contributing to textile sustainability. An example of a bio-based textile is an orange-waste film, which is plant-based and biodegradable and possesses mechanical properties which are comparable to some commodity plastics. The research project presented in this article aimed to explore orange-waste film as a new material for textile and fashion design and highlights how experimental co-design processes and innovation involving orange waste film as a textile material adds a new layer of material understanding to both textile design and technology-driven material research. Material-development methods were used to develop the orange-waste film, as were textile design methods with a focus on surface design. The results show that material variables such as tensile strength and elongation are dependent on the grinding process and drying temperature used for the raw material, as these determined the quality and durability of the orange-waste film and its applicability to the field of textile design. The use of orange waste in the creation of textiles opens up for more ways of thinking about and working with materials, and orange waste could become a desirable raw material for textile design on the basis that it introduces certain aesthetic and functional possibilities through its visual and tactile expression and material behaviour, in addition to defining methods of producing textiles.

Abstract: Textile materials generally have intrinsic properties, such as flexibility, light volume density, strength, tenacity, comfort and softness. Based on these characteristics, the textile material is generally given a special additional function, such as hydrophobic or hydrophilic properties. The addition of these special functions to the textile industry is generally using conventional wet methods that require more energy and water as well as more chemicals need and expensive price. Plasma technology is one of the dry process technologies and it can reduce the use of chemicals that can pollute the environment. This article describes the application of atmospheric plasma corona discharge technology in the textile sector, especially its use in modifying wetting properties on the surface of polyester cotton (TC) 70%. The results showed that by varying the time of plasma treatment on 70% TC cotton polyester fabric with density of weft and warp respectively 70 strands / inch and 60 strands / inch we found that there was a change in the wetting properties of the fabric with increasing hydrophilic properties of the fabric. SEM images show the example of morphology of cotton polyester fabric surfaces treated with time of exposure by plasma at one minute (60 s) at 3 kV of output voltage as the optimal exposure time and applied voltage to enhance the wetting properties.
