CURRENT PRACTICES, TRENDS, AND DEVELOPMENTS IN LABORATORY-TYPE WET SPINNING TECHNOLOGIES

Öz

The increasing interest in wet-spun filaments has also sparked enthusiasm for custom-designed wet spinning setups. Tailored laboratory systems are valuable both for exploring novel polymer compositions and for modifying the setup components in the future. In this study, a concise outline of current practices, trends, and developments in laboratory-type wet spinning technologies is provided. Also, a custom-designed laboratory-scale wet spinning setup is introduced in detail. The constructed setup combines the controllable syringe, traveller, and winding unit via a single digital interface. The modular needle holder of the setup provides air gap spinning and multiple injection angles. The speeds of both the traveller, which regulates filament winding, and the winding cylinder can be adjusted via the touchscreen monitor. Such an integrated, complex, and modular system enables precise control of process parameters. Also, it is possible to precisely examine the effects of process-related parameters on the filament properties. Moreover, multiple control systems with a single interface provide the ability to draw filaments under controlled tension. This system further offers an adaptable framework for new developments, such as data monitoring and module integration, offering considerable versatility and cost advantages in both research and production processes.

Laboratuvar Tipi Yaş Çekim Teknolojisindeki Güncel Uygulamalar, Trendler ve Gelişmeler

Öz

Yaş çekim teknolojisi ile üretilmiş filamentlere olan artan ilgi, özel olarak tasarlanmış yaş çekim düzeneklerine yönelik ilgiyi de beraberinde getirmiştir. Özel tasarım laboratuvar ölçekli düzenekler, hem yeni polimer sistemlerinin araştırılması hem de gelecekte düzenek bileşenlerinin modifiye edilebilmesi açısından oldukça önemlidir. Bu çalışmada, laboratuvar tipi yaş çekim teknolojisindeki mevcut uygulamalara, eğilimlere ve gelişmelere dair kısa bir genel bakış sunulmaktadır. Ayrıca, özel tasarım laboratuvar ölçekli bir yaş çekim düzeneği ayrıntılı olarak tanıtılmaktadır. Kurulan düzenek, tek bir dijital arayüz üzerinden kontrol edilebilir bir enjektör, gezdirici, ve sarım ünitesi ana bileşenlerinden oluşmaktadır. Modüler olarak tasarlanmış iğne tutucu, hem enjeksiyon mesafesinde hem de enjeksiyon açısında varyasyonlu üretim sağlayabilmektedir. Filament sarımını yöneten gezdirici ve sarım silindirinin hızları dokunmatik ekran monitörü aracılığıyla ayarlanabilmektedir. Bu tip bir entegre ve modüler sistem, proses parametrelerinin hassas bir şekilde kontrol edilmesine olanak sağlamaktadır. Ayrıca, prosesle ilişkili parametrelerin nihai filament özellikleri üzerindeki etkilerinin hassas bir şekilde incelenebilmesini de mümkün kılmaktadır. Ek olarak, tek bir arayüze sahip çoklu kontrol sistemi, kontrollü gerilim altında filament üretimini sağlamaktadır. Bu sistem, veri izleme ve modül entegrasyonu gibi yeni gelişmelere uyarlanabilir bir çerçeve sunarak, hem araştırma hem de üretim süreçlerinde önemli ölçüde esneklik ve maliyet avantajları sunmaktadır.
