Abstract
The invention provides a method for producing elastic knitted fabric on a Raschel or tricot machine. The method utilizes a four bar knitting structure and four thread feeders. The needle guides of the first and fourth bars are threaded with non-elastic yarn, while the needle guides of the second and third bars are threaded with elastic yarn. Each elastic thread is worked in plating with the respective non- elastic thread.

Method for producing elastic knitted fabric on a Raschel or tricot machine, characterised by the fact that it uses a knitting machine with basic four bar knitting structure and four thread feeders;
- the needle guides of the first and fourth bars are threaded with non-elastic yarn, while the needle guides of the second and third bars are threaded with elastic yarn;
- each elastic thread is worked in plating with the respective non-elastic thread.
An elastic warp knitted fabric, comprising:
- a knit having four threads comprising two elastic threads and two non-elastic threads, wherein each said elastic thread is knitted in parallel with at least one of said non-elastic threads, said knit forming a pattern using a four-bar knitting structure, said pattern selected from the group consisting of:
