Örme Kumaşların Elektrik İletkenliğinin Araştırılması

Son zamanlarda, elektronik tekstillerin kullanımı elektromagnetik kalkanlama, biyomedikal aletler, alan etkili transistörler, enerjidönüşümü ve depolama vb. gibi birçok alan için araştırılmaktadır. Bu çalışmada, iletken kumaşlar paslanmaz çelik iplik kullanılarakörme tekniği ile üretilmiştir. Örme kumaşlar düz, haroşe, 1x1 rip, ve 2x2 rip olmak üzere dört farklı konstriksüyonda üretilmiştir. Örmeişleminden sonra numunelerin ilmek iplik uzunluğu, ilmek yoğunluğu, gramjı, kalınlığı, gözenekliliği ve iletkenliği belirlenmiştir. Eldeedilen sonuçlara göre, örme parametreleri kumaş konstriksiyonuna göre değişiklik göstermektedir. Ayrıca, kumaş konstriksoyunu numunelerin gözenekliliğini ve elektrik iletkenliğini etkilemektedir. Düz örgü kumaş numunesi diğer numunelere göre daha yüksekgözenekliliğe sahiptir. Tüm örgü yapıları ile karşılaştırıldığında, 2x2 rib örgü kumaş numunesinin elektrik iletkenliği diğer kumaşnumunelerinden daha yüksektir. Bu kumaş elektronik aletlerde elektronik tekstil olarak kullanılabilir.

Electrical Conductivity Investigation of Knitting Fabrics

Recently, using of electronic textiles have been investigated for many fields due to their various useage at electromagnetic shielding,biomedical devices, field-effect transistors, energy conversion and storage, etc. In this study, conductive fabrics were fabricated withusing stainless steel yarn by knitting techniques. The knitted fabrics were produced four different constructions which are plain, garter stitch, 1x1 rib, and 2x2 rib knitting structure. After the knitting process, mass per unit area, loop yarn length, stitch density, thickness,porosity and conductivity of samples were analyzed. According to results, knitting parameters differ from fabric construction.Furthermore, fabric construction affects the porosity and electrical conductivity of samples. Plain knitting fabric sample has higherporosity than other samples. Compared with all knitting structures, electrical conductivity of 2x2 rib knitting fabric sample is higherthan other fabric samples. This fabric can be used as electronic textile in electronic device.
