Ground structures in warp knitting
- Pillar stitch or plain stitch:
- In a pillar stitch, the over and underlappings are always carried out across the same needle and each needle knits a chain of stitches. Therefore there are no lateral connections with neighbouring courses and no fabric is created. This stitch is commonly used with other lapping movements to form a fabric.
- Tricot lapping or 1 X 1:
- Tricot is the simplest of these movements, creating overlaps in alternate wales at alternate courses with just one thread which is crossed between adjacent wales.
- Cord lap or 2 X 1:
- Two threads will cross between wales with a 2 X 1
- Satin lap or 3 X 1:
- Three threads will cross between wales with a 3 X 1
- Velvet lap or 3 X 1:
- Four threads will cross between wales with a 4 X 1
- Atlas lapping
- In the atlas construction the laps are continued in the same direction over minimum of two consecutive courses and then return to the starting point in the opposite direction.
