Lifleri bir arada tutmak ve mukavemetlerini arttırmak için büküm uygulanır. Birim uzunluk başına büküm, ipliğin ve kumaş yapısının mekanik ve performans özelliklerini değiştirir. Bu çalışmada polyester, viskon ve polyester-viskon elyaflardan boyanmamış ve boyalı formlarda Ne 10, Ne 25 ve Ne 40 numaralarında ve 3, 3,5 ve 4 büküm katsayılı ring iplikler üretilmiştir. Çalışmanın ilk bölümünde bu iplikler üzerinde kalite testleri yapılmış ve sonuçlar analiz edilmiştir. Daha sonra Ne 25 ve Ne 40 iplikler tek yataklı SDL yuvarlak örgü makinesinde süprem kumaşa dönüştürüldü. Kullanılan laboratuvar tipi örgü makinesinin inceliği Ne 10 ipliğe uygun olmadığından bu numaradaki iplik numuneleri kumaş numunelerine dönüştürülememiştir. Elde edilen örme kumaşlar, SDL Atlas hava geçirgenlik test cihazında hava geçirgenlik testine tabi tutuldu. Çalışmanın son bölümünde, üretilen kumaşlardan Ne 25'li gri ipliklerden artan basınç aralıklarında elde edilen numunelere hava geçirgenlik testi uygulanmıştır. Bu çalışma sonucunda, büküm katsayısının kumaşların hava geçirgenliğine etkisi belirlenmeye çalışılmıştır. Sonuçlar grafikler ve istatistiksel programlar aracılığıyla analiz edildi.
The curve is applied to keep the lifts together and increase their strength. The unit changes the mechanical and performance characteristics of the curve, thread and fabric structure per length. In this study, polyester, viscon and polyester-viscon fibers were not painted and painted in forms of Ne 10, Ne 25 and Ne 40 and 3, 3,5 and 4 curved ratio ring lines were produced. In the first part of the study, quality tests were performed on these wire and the results were analyzed. Then the Ne 25 and Ne 40 wire were converted into super fabric in the single-bed SDL round wire machine. The thinness of the used laboratory type wire machine is not suitable for the 10 wire, so the wire samples in this number are not converted into fabric samples. The obtained steam tissues were subjected to the air tolerance test in the SDL Atlas air tolerance test device. In the last part of the study, the air tolerance test was applied to the samples obtained in increased pressure intervals from produced weeds from Ne 25 grey wire. As a result of this study, it was tried to determine the impact of the curvature rate on the air permeability of tissues. The results were analyzed through graphics and statistical programs.
Twist is applied to the fibers to keep them together and to raise their strength. Twist per unit length changes the mechanical and performance properties of the yarn and the fabric structure. In this study, ring yarns were produced from polyester, viscose and polyester-viscose fibers in undyed and dyed forms and Ne 10, Ne 25 and Ne 40 counts and with 3, 3,5 and 4 twist coefficients. In the first part of the study, quality tests were performed on these yarns and the results were analyzed. Then, Ne 25 and Ne 40 yarns were transformed into single jersey fabric via a single bed SDL circular knitting machine. The fineness of the labaratory type knitting mill is not suitable for Ne 10 yarns therefore these yarns were not transformed into knitted samples. The obtained knitted fabrics were subjected to air permeability test in SDL Atlas air permeability tester. In the last part of the study, air permeability test was applied to the samples obtained from undyed yarns with Ne 25 from the produced fabrics at increasing pressure ranges. As a result of this study, the effect of twist coefficient on the air permeability of fabrics was tried to be determined. The results were analyzed through graphs and statistical programs.
