Difference between Single Jersey and Interlock Circular Knitting Machine

There are four basic structure of knitted fabric; plain structure, rib structure, interlock structure and purl structure. Different types of knitting machine required to produce these knitted fabrics. The plain structure can be produce by single jersey circular knitting machine, where the cylinder with needle revolves on the stationary cam. The interlock structure are required two sets of needles arranged in horizontally and vertically. In this article I will differentiate single jersey and interlock circular knitting machine.
