Yarn and spinning technology is a complex process that is a combination of raw materials, machinery, and automation technology where continuous improvements, researches and innovations run progressively. For the evolution of spinning technology, academic publications, postgraduate theses, and technological contributions of related shareholders must be considered as adherent supplements. Aim of this study is to examine the accomplished 236 postgraduate theses related to conventional and novel textile fibre types, staple spun/filament yarn technology and machinery, yarn types with structural and functional varieties, and modified spinning technologies in Turkish Universities. Moreover, it is aimed to reveal any trend in theses on yarn technology and the regional textile clusters in Türkiye. The methodology of the pursuit is a quantitative assessment where postgraduate level, thesis subject, year of thesis defence, and raw materials used in the theses are concerned. The findings showed that researchers focussed on conventional spinning systems and yarns in parallel with the spinning capacity and import potential of the country. Other extractions of the study are; classical ring system is mostly studied by the researchers, modern spinning technologies are included in many theses, reflections of global circumstances are distinguished in theses with keywords of manmade/recycled fibres, and blended yarns.

Alginate, categorized as a natural-based biodegradable polymer, stands out for its inherently exclusive properties. Although this unique polymer is widely processed using film, coating, and membrane technologies for different usage areas, textile applications are still limited. This study aims to compile promising approaches that will pave the way for the use of wet-spun alginate filaments in textile applications. In this regard, this study provides information about the molecular structure of alginate, the gel formation mechanism, and cross-linking using different techniques. Our literature review categorizes parameters affecting the mechanical properties of wet-spun alginate filaments, such as the effect of ion source and spinning dope concentration, needle diameter, temperature, and coagulants. Following this, a detailed and comprehensive literature review of the various approaches, such as use of additives, preparation of blended filaments, and grafted nanocrystal addition, developed by researchers to produce composite alginate filaments is presented. Additionally, studies concerning the use of different cations in the coagulation phase are reported. Moreover, studies about the functionalism of wet-spun alginate filaments have been offered.

Fashion Industry Charter for Climate Action is consequence of a long-term international meeting chain, called the COP-Conference of Parties. The COP is an international climate conference that unites the signatory countries (195 countries + the European Union) of the United Nations Framework Convention on Climate Change (UNFCCC) since 1995. The goal of the consecutive meeting chain is to manage the interiorization of the Convention and negotiate new commitments. Fashion Industry Charter for Climate Action is prepared and launched by the patronage of UN Climate Change at COP24 in Katowice, Poland, in December 2018 and renewed at COP26 in Glasgow, UK, in November 2021. The stakeholder of the charter is the global fashion stakeholders including textile, apparel and clothing industries with a holistic commitment. The charter contains the vision to achieve net zero emissions by 2050 in line with keeping global warming below 1.5°C from pre-industrial levels defined in the COP 21 of Paris Agreement in 2015. In line with the launched charter, planned tasks of global fashion industry are focused on decarbonisation, reduction of greenhouse gas emission (GHG), renewable electricity utilisation across supply chains, implementation of tools and measures about broadening climate actions. Therefore, the paper is aimed to inform and increase the awareness about current climate actions of global fashion industry. [ABSTRACT FROM AUTHOR]
