ÖgeDevelopment of biodegradable poly(butylene succinate) based nanofibrous webs via solution-blow spinning technology for N95 respiratory filters(Springer, 2024)As a result of the COVID-19 outbreak, millions of people are wearing face masks (including disposable surgical face masks), and many used masks, particularly disposable masks, are entering the environment and increasing pollution. The applicability of nanofibers in the field of filtration is considerable, and it has replaced environmentally friendly materials in research in this area. Solution-blown spinning (SBS) is an efficient and straightforward method for creating micro and nanofibers that allow quick fiber deposition on any substrate. Poly(butylene succinate) (PBS) is an environmentally safe biopolymer with unique properties, such as processability and flexibility, that has piqued the interest of industry and researchers. Hence, an eco-friendly air filter based on PBS nanofibers was fabricated using SBS. This solution-blown spun PBS filter was demonstrated as an air filter for the first time. The findings demonstrated that a weight of around 19.3 g/m2 PBS webs with a mean diameter of 199 nm was adequate to produce a filtering performance of 95.26% with a pressure drop of 251 Pa at a flow rate of 85 L/min. The fast and economic features of the SBS process, as well as the environmentally friendly nature of the PBS polymer, may be a considerable contribution to the development of green filters.

ÖgeInternational Textile and Fashion Congress, ITFC 2023 : proceeding book(İTÜ Yayınevi, 2023)We have organized international & national congresses and R&D days for our community through-out 40 years in irregular sequences up-to-now, neverthless hereafter, our purpose is to commence a new bi-annual international textile congress series at ITU starting from year 2023 for our distinguished community in view of the fact that year 2023 is an extremely significant year for us: 250th anniversary of Istanbul Technical University, 100th anniversary of Turkish Republic and 40th anniversary of Textile Engineering Department, ITU. In the core of Istanbul, our aim is to organize a meeting point for all textile & fashion/retail researchers as well as fashion designers around the world at the Department of Textile Engineering at Gumussuyu/Beyoglu. We are expecting to strengthen connections with our colleagues, industry members and professionals from across the world, along with sharing our knowledge and experience on innovative textiles and fashion trends tackling global challenges at a new era after pandemics. Thus, we aim to mention the importance of textile in all global struggles that have affected the whole world since 2019 and to witness the latest developments in textile & fashion.
