The effects of fabric density and nozzle type on structural properties, dimensional stability and spirality of single jersey knitted fabrics

Süprem örgü kumaşlar yazlık giysi üretiminde yaygın olarak kullanılmakta ve bu tip kumaşlar için önemli sorunlardan biri yıkama sonrası boyut stabilitesidir. Bu çalışmada, iplik üretiminde düze tipi ve kumaş üretiminde sıklık değişiminin ham ve boyalı süprem kumaşlarda, boyutsal stabilite ve may dönmesi üzerindeki etkisi incelenmiştir. Süprem kumaşlar %100 pamuk, Ne 30/1 open-end rotor ipliğinden üretilmiştir. İplik üretiminde beş farklı seramik düze tipi kullanılmıştır. İplik ve ticari değer/kalite şartları gözetilerek 14-17 cm minimum ve maksimum değerler arasında süprem kumaş olarak örülmüştür. Sonuç olarak düze tipinin boyutsal stabilite ve may dönmesi üzerinde istatiksel açıdan önemli bir etkisinin bulunmadığı, ancak ilmek iplik uzunluğunun (sıklık değişiminin) istatiksel açıdan önemli etkiye sahip olduğu tespit edilmiştir.

Düze tipi ve sıklık değişiminin süprem örgü kumaşlarda may dönmesi ve boyutsal stabilite üzerindeki etkisi

Single jersey knitted fabrics are widely used in production of summer clothing and dimensional distortion caused by domestic laundery is an important issue for this type of fabrics. In this study, the effects of fabric density and nozzle type on structural properties, dimensional stability and spirality of single jersey knitted fabrics were investigated for both grey and dyed state. Fabrics were produced with 100% cotton, Ne 30/1 rotor spun yarn. Five different ceramic nozzle types were used in yarn production. The yarns were converted to single jersey knitted fabrics adjusting the yarn loop length between 14-17 cm on the machine as they were the minimun and maximum values limited by the yarn type, machine and commercially accepted conditions. The effect of nozzle type on dimensional stability and spirality is found statistically insignificant, whereas the effect of yarn loop length is significant.
