Effect of backed yarn characteristics on two-thread fleece knitted fabric properties

The influence of backed yarn linear density and its twist factor on two-thread fleece knitted fabric properties has been studied. Experiments are conducted on both finished and raised fabrics. Four levels of linear density and two levels of twist factor are used for backed yarn. Knitted fabrics weight per square meter, shrinkage, spirality, thermal comfort characteristics, bursting strength and abrasion resistance are tested. Results show that by increasing yarn linear density, the fabric weight per square meter and thickness increase, while shrinkage and spirality improve. Raising process enhances fabric thermal comfort characteristics, while the yarn twist factor exhibits insignificant effect on many fabric characteristics
