Acoustical absorptive properties of spunbonded nonwovens made from islands-in-the-sea bicomponent filaments
Suvari, Fatih; Ulcay, Yusuf; Maze, Benoit; Pourdeyhimi, Behnam (Taylor and Francis Ltd., 2013)In this paper, we report on the acoustical absorptive behavior of spunbonded nonwovens that contain bicomponent islands-in-the-sea filaments. Nylon 6 (PA6) and polyethylene were used as the islands and the sea polymers, ... -
Comparing the Prediction Capabilities of Artificial Neural Network (ANN) and Nonlinear Regression Models in Pet-Poy Yarn Characteristics and Optimization of Yarn Production Conditions
Yıldırım, Kenan; Öğüt, Hamdi; Ulcay, Yusuf (Inda, 2017)In the manufacture of yarn, predicting the effect of changing production conditions is vital to reducing defects in the end product. This study compares, for the first time, non-linear regression and artificial neural ... -
Eriyikten katkılı antibakteriyel polyester filament ipliklerin karakterizasyonu
Çelen, Onur (Bursa Teknik Üniversitesi, 2013)Bu çalışmada, gümüş katkılı antibakteriyel tozların iplik çekimi sırasında polyester filament ipliğe katılabilmesi için gerekli masterbatch çalışmaları yapılmıştır. Hazırlanan masterbatchlerin üretim prosesinde polyester ... -
An experimental study and model development of poly(ethylene terephthalate) yarn morphology
Yıldırım, Kenan; Ulcay, Yusuf (Walter De Gruyter Gmbh, 2014)In this study, macromolecular arrangements in fibers were investigated and a novel approach based on model development for partially oriented (POY) polyethylene terephthalate (PET) yarn morphology was proposed. Differential ... -
