Examining of the Effect of Fabric Structural Parameters on Dimensional and Aesthetic Properties in Pile Loop and Cut-Pile Loop Knit Fabrics

This paper examines the effects of fabric structural parameters such as pile yarn number (Ne 30, Ne 26 and Ne 24), ground yarn number (90 Td and 70 Td), pile height (2.2 mm, 2.5 mm and 2.8 mm) on the dimensional stability and spirality properties of the pile loop and the cut-pile loop knit fabrics. To determine their relationship and significance, one way ANOVA analyses and Pearson correlation analyses are conducted. It is found that cut-pile loop fabrics have more dimensional stability and less spirality than pile loop fabrics. Increased cpc, wpc and parallel with stitch density increase dimensional stability and they decrease spirality partially. It is observed that shrinkage in wale direction is more than shrinkage in course direction. The higher pile height increases fabric shrinkage, decreases spirality in pile loop fabrics, increases spirality in cut-pile loop fabrics. In pile loop fabrics, the thicker pile yarn increases shrinkage in wale direction and increases spirality. Ground yarn number is not effective on dimensional stability and spirality.
