Towards circular economy in the textiles and clothing value chain through blockchain technology and IoT: A review

The textile and clothing industry sector has today a big environmental impact, not only due to the consumption of water and the use of toxic chemicals but also due to the increasing levels of textile waste. One way to reduce the problem is to circularise the, currently linear, textile and clothing value chain, by using discarded clothes as raw material for the production of new clothes, transforming it into a model of circular economy. This way, while reducing the need to produce new raw materials (e.g. cotton), the problem of textile waste produced is also reduced, thus contributing to a more sustainable industry. In this article, we review the current approaches for traceability in the textile and clothing value chain, and study a set of technologies we deem essential for promoting the circular economy in this value chain – namely, the blockchain technology – for registering activities on traceable items through the value chain, and the Internet of Things (IoT) technology, for easily identifying the traceable items’ digital twins.

The Psychological Profile of Tunisian SMEs Founders Amid the COVID-19 Crisis

The purpose of this paper is to determine the psychological profile of the Tunisian SMEs founder amid the COVID-19 crisis. The results of this research demonstrated that their psychological profile in times of COVID-19 crisis is quadridimensional and that each of these four dimensions (tolerance for ambiguity and uncertainty, attitude towards risk, self-confidence and locus of control) are unidimensional. This research was conducted in three Tunisian industries (textiles and clothing industries, agro-food industries and industries of ceramic and glass building materials) via the administration of a questionnaire via LinkedIn (between March, 15 and May, 15 2020) to more than 400 SMEs’ founders. The critical contributions of this research are the clarification of the role of psychological factors in the field of entrepreneurship, which remains unclear, by enriching previous research on entrepreneurial personality. The main findings of this study: (1) the four key psychological traits correspond to the “specific traits” of an entrepreneur; (2) these “specific traits” are more suitable to study the profile of the SME’s founder profile at the time of crisis than the more “stable traits” — the Big Five traits; (3) the psychological profile of the SME’s founder in a hyper-turbulent environment (namely the COVID-19 crisis) correspond to the psychological entrepreneurial profile.

TURKISH TEXTILES DESCRIBED IN PAINTINGS BY MILITARY PAINTER HALIL PASHA

During the Ottoman Empire, which was established in Anatolia after the Seljuks, many developments were made in the name of art for 600 years. Especially thanks to the Ottoman Empire's value to the artist and art, very good works have been produced in many fields. In addition to branches such as calligraphy, illumination, miniature and marbling, fabrics, carpets and rugs, which attract the attention of the whole world in the field of textile, were also woven. The art of weaving experienced its brightest period in terms of weaving technique, color and pattern in the Ottoman Empire. It is understood that weaving, which continued to be produced traditionally in Ottoman cities, continued its existence as an important cultural element and sector. The clothes of the Ottoman sultans kept after their death and the qualities of the fabrics used in the palace convey very important information at the point of understanding the importance of weaving. The diversity and richness of the weavings and textiles produced in many documents belonging to the period can be clearly seen. In this context, this rich weaving and textile diversity has taken an important place in Turkish culture. Especially this rich variety of weaving and textiles has been painted by many painters in almost every period and has gained an important place in terms of conveying information about their periods. In this study, some of Halil Pasha's paintings in which he displayed an objective and objective approach with a realistic style, some of which are in an orientalist style, are discussed as subject. In the study, will focus on Halil Pasha's life, his understanding of art and the textiles and clothing he depicted in some of his paintings. The textiles and clothes in the paintings were discussed in terms of characteristics such as color, pattern, and texture. Key Words: Textile, weaving arts, clothing, painting, carpet.

Research status and prospect of intelligent fibres and textiles

Intelligent fibre is a kind of fibre that integrates sensing and information processing. It is similar to biological materialsand has intelligent functions such as self-perception, self-adaptation, self-diagnosis, and self-repair. Intelligent textilesrefer to textiles that have sensing and responding functions to the environment. Intelligent fibres and their textiles notonly have the ability to perceive and respond to external stimuli but also have the ability to adapt to the externalenvironment. In recent years, the research on intelligent fibres has achieved many results in the world, and it is widelyused in textiles and clothing industry. Therefore, this paper summarized the research status of intelligent fibre andintelligent textile worldwide, and put forward the research direction in the future. This paper introduced the propertiesand research status of five kinds of main intelligent fibres, including phase change fibre, shape memory fibre, smarthydrogel fibre, optical fibre and electronic intelligent fibre, and summarized their application in textiles. This paper alsointroduced the research status of five important intelligent textiles, including intelligent temperature control textile, shapememory textiles, waterproof and moisture permeable textile, intelligent antibacterial textile and electronic intelligenttextile. Moreover, it forecasted the development prospects of intelligent fibres and textiles, and pointed out developmentdirection in three aspects of performance optimization, green and safety, industrialization. It provided research referenceand guidance for future intelligent fibre and intelligent textile.

DESIGNING THE BASIS OF THE SHOULDER PRODUCT USING THE TECHNOLOGY OF ECOLOGIKAL PROCESSING OF TEXTILE MATERIALS

In condition of nowadays, it raises the question of life and professional realization of the individual, the ability to use and acquire knowledge throughout life, to build own professional path, while having a high level of general and professional culture. Future specialists of professional education (Technology of light industry goods) acquire object and professional competencies in the process of educational and research activities, including the mastering of the method of clothing design that is decisive. The development of general competencies is no less important, especially awareness of the values of sustainable development of society, including environmental culture, which is formed in the process of education. The improvement of this training helps students to do creative projects on the technology of ecological processing of textile materials, which corresponds to the introduction of the principles of sustainable fashion into the educational process. The article also describes the technology of "upcycling", which expects the reuse of textiles and clothing. It is the process of creating a new thing from another one that is not used any more. Its potential is the formation students’ environmental culture and the relevant skills of resource conservation. Since the amount of material is limited, there is a need to build an accurate design of the product base, which can be used further modeling a new product without extra elaboration. The article presents the substantiation of one of the methods of constructing the basis of the shoulder product – dip transfer welding, which is one of the effective one when students do creative projects on the manufacture of garments using the technology of ecological processing of textile materials. Involving students in such projects contributes to the formation of environmental culture, forms an idea of sustainable fashion, and it is an effective way to slow down fashion. The creating of an algorithm for building the basis of the shoulder product on a non-standard figure will contribute to the formation of object competencies of students during doing creative projects using the technology of ecological processing of textile materials.

Digitalization of garment in the context of circular economy

One of the principles of the circular economy is to recycle used or unused materials, in order to reuse them in the creation of new objects or the restoration of old ones. But due to the fragility, some of these materials, such as old textiles and clothing, are quite difficult to handle. This study presents a completely digital method with the help of which two pieces of clothing of different ages and physical properties, have been restored and stylized; the two pieces are made up of a traditional Romanian women’s shirt about 100 years old and a modern sports t-shirt. For the application of the principles of the circular economy, the restoration-stylization processes of the pieces were based on the material and ornaments collected digitally from a series of old Romanian towels, which are currently no longer used. For this we considered the creation of 3D models of all the materials considered by the method of photogrammetry in Agisoft Metashape 1.6.2 Professional Edition and their processing in MeshLab 2020.2, as well as the vectorization of traditional motifs in ArcGis 10.6. Such an approach limits to the minimum the numbers of attempts that the restores have at their disposal while also allowing the obtaining, storage and transmission of information about traditional textiles, aimed at capturing the imagination of modern artists and designers to restore them for future generations.

The circular economy in the textile industry

In recent years, there has been an increase in the production of textiles and clothing, which is the result of an increase in the global population and an improvement in living standards. The consequence of this fact is the unlimited use of resources for the needs of the production process of textiles and clothing, as well as an increase in the amount of generated textile waste, which is currently not treated adequately. For the textile industry to have a chance in the future to take advantage of environmental, economic and social opportunities that it is currently unable to do, it is necessary to transform the current, linear system into a circular system. The paper presents the possibility of implementing the basic principles of the circular economy in the textile and clothing industry. According to the principles of the circular economy, the textile industry is based on the realization of four activities: elimination of unwanted substances and release (emission) of microfibers, increasing the utilization of clothing, improving the recycling sector, efficient use of resources and switching to renewable sources.
