POLİPROPİLEN (PP) SPUNBOND DOKUNMAMIŞ KUMAŞLARIN ALANSAL AĞIRLIK, ÇEKME MUKAVEMETİ VE KOPMA UZAMASI ÖZELLİKLERİNİN GÖRÜNTÜ İŞLEME YÖNTEMİ KULLANILARAK HASARSIZ TESPİTİ

Görüntü İşleme Yöntemi, dokunmamış kumaşların boncuklaşma eğilimi ve dokuma ve örme kumaşlarda hasar tespiti gibi tekstil uygulamalarında yaygın olarak kullanılmaktadır. Görüntü işleme yöntemi ile kumaş ağırlığının tahmin edilmesi ile ilgili literatürde birçok çalışma bulunmaktadır. Fakat görüntü işleme yöntemi kullanılarak çekme mukavemeti ve kopma uzamasının kumaşlarda tahmini konusu çok az sayıda makalede işlenmiştir. Bu makalede, farklı ağırlıktaki polipropilen spunbond dokunmamış kumaşların (12g/m2, 20g/m2, 25g/m2, 30g/m2, 50g/m2) ağırlık, çekme mukavemeti ve kopma uzaması özelliklerinin görüntü işleme yöntemi ile tahmin edilmesi incelenmektedir. Deneysel sonuçlar ile makalede önerilen istatistiksel yöntemle tahmin edilen kumaş özellikleri karşılaştırılacaktır. Bu makalede incelenen bağıntılar yardımıyla, çekme mukavemeti cihazına sahip olmayan polipropilen spunbond dokunmamış kumaş üretim fabrikaları üretim sırasında kumaşların çekme mukavemetlerini ve kopma uzamalarını tahmin edebileceklerdir

NONDESTRUCTIVE PREDICTION OF AREAL WEIGHT, GRAB TENSILE STRENGTH AND ELONGATION AT BREAK OF POLYPROPYLENE (PP) SPUNBOND NONWOVEN FABRICS USING DIGITAL IMAGE ANALYSIS

Digital image analysis is widely used in textile applications including fabric pilling behavior of nonwovens and defect detections in woven and knitted fabrics to predict some properties and online control of the quality of nonwoven materials. The estimation of fabric weight using digital image analysis is well established in the literature. But little information could be found about the estimation of grab tensile strength and elongation at break using digital image analysis. This paper investigates the estimation of weight, tensile strength and elongation at break values of polypropylene (PP) spunbond nonwoven fabrics at various weights (12g/m2, 20g/m2, 25g/m2, 30g/m2, 50g/m2) using digital image analysis. The relationships between the experimentally measured material properties and statistical parameters computed using digital image analysis is introduced. With the help of the correlations provided in this article, PP spunbond fabric production companies, which do not have tensile testing device, could roughly estimate the grab tensile strength and elongation at break values of the PP fabrics
