Abstract

Bu makalede, uygulanan örgü yapısı ile çorabın üretiminde kullanılan zemin ve dolgu iplik numaralarının kompresyon çoraplarının esneklik ve patlama mukavemetine etkilerinin incelenebilmesi amacıyla yapılmış deneysel bir çalışma sunulmuştur. Bu amaçla işletme şartlarında diz altı tipte kompresyon çorapları üretilmiş, çorapların patlama mukavemeti ve esneklik değerleri ölçülmüştür. Testler sonucunda, kompresyon çorabının örgü raporunda yer alan dolgu ipliği sıra sayısı arttıkça çorapların sıra yönlü esneklik değeri azalmaktadır. Kompresyon çoraplarının bilek bölümlerinde, zemin ve/veya dolguda kalın iplik kullanılması durumunda patlama mukavemetinin daha yüksek olduğu görülmüştür. Dolguda kalın iplik kullanıldığı durumda çorapların sıra yönlü esneklik değeri daha yüksek çıkmaktadır. Esneklik testinden elde edilen kumaş yönlü deformasyon ile patlama mukavemeti testinden elde edilen deformasyon değerleri arasında yüksek korelasyon bulunmaktadır (korelasyon katsayısı 0.70)

THE EFFECTS OF INLAY YARN AMOUNT AND YARN COUNT ON EXTENSIBILITY AND BURSTING STRENGTH OF COMPRESSION STOCKINGS

Abstract

In this study, an experimental work is presented to determine the effects of body and inlay yarn counts and inlay yarn amount on the extensibility and the bursting strength of knitted compression stockings. For this purpose calf high compression stockings were produced, and then bursting strength and extensibility of these stockings were tested. The results reveal that, when the course number of inlay yarns at knit structure increases, there is a significant decrease in course way extensibility values ofcompression stockings. Bursting strength values of compression stockings knitted with coarse body and/or inlay yarns were higher than that of compression stockings with fine body and/or inlay yarn. The compression stockings with coarse inlay yarns have the highest course way extensibility values. As the result of correlation analysis, we confirmed that there was the strong correlation between “fabric way strain” which obtained by extensibility test and “the strain” which obtained by bursting strength test (correlation factor: 0.70)
