RESEARCH THE CURLING BEHAVIOR OF SINGLE JERSEY WEFT-KNITTED FABRICS

Abstract

Single jersey fabric commonly used for garment because of high production and simple
technological conditions. The fabrics are light and soft, that make them suitable for different
garment group such as underwears, T-shirts, sportwears,… However, the single knitted
fabrics will curl on the edges. The curling is one of the disadvantages of single-knitted fabrics. It
effects on cutting, sewing, and linking processes. This phenomena of single fabric influenced
by different factor such as elasticity yarn, loop density… In this paper, we have investigated
an influence of investigated position on horizontal and vertical curling behaviour of single
jersey weft knitted fabrics. Three CVC (60% cotton, 40 % polyester) single jersey fabric have
been knitted with different loop density, which are 142, 138 và 136 stitches/100mm by wale
direction and 193, 187, 186 stitches/100mm by course direction. Measurement of the fabric
curling have been carried out at different position at the fabric edge in order to study the
curling behaviour on depending position and the fabric length. The results shown that fabric
curling increased in mouving to the middle position of the fabric edges. Futhermore, the
curling tented more important in the course direction than it was in the wale direction.
