In case of warp knitting production, there are two types of knitting machine used, where one is tricot warp knitting and the other one is raschel warp knitting machine. This article has presented some basic difference among tricot warp knitting and raschel warp knitting machine.

Raschel Warp Knitting Machine
Here, warp knitting machine gauge expressed in needle per inch.
Here, machine gauge expressed in needle per two inch.
Three links per course.
Two links per course.
Bearded needle was used in the past in tricot warp knitting m/c, but now a day’s compound needle is used.
In case Raschel warp knitting machine, latch needle was used together with a blade or wire.
Here, chain link numbering is 0, 1, 2, 3, ……., etc.
Here, chain link is numbered in even numbers 0, 2, 4, ……., etc.
Here, sinker function is knocking over, holding down and supporting the fabric.
Here, sinker performs the function of holding down the loops whilst the needle rises.
High speed fabric production is done here.
Lower speed fabric production than tricot m/c.
Here, the warp sheet pass over the top of the guide bar rocker shaft to their tension.
Here, the warp sheets pass down the guide bar.
The knitted fabric is drawn away towards the batching roller almost at the right angles to the needle bar.
Here, the fabric is drawn downwards from the knitting needles which are almost parallel to the bar at an angle of 120°-160°.
Mechanical attention is carried out at the front of the tricot warp knitting machine.
Here, mechanical attention is carried out at the back of the raschel warp knitting machine.
The sinkers are joined together to each other at the front and back.
The sinkers are not joined together by a lead across their ends nearest to the needle bar.
Here, the guide bars are numbered from the back towards and the front of the machine.
Here, the guide bars are numbered from the front of the machine.
The warp beams are accommodated in an inclined arc towards the back of the machine there top.
The warp beams are arranged above the warp beams are arranged above the needle centered over the rocker shaft.
The sinker never move clear of needles.
They can move clear of the needles towards the back of the machine for the rest of the knitting cycle.
Warp beams are accommodated in an inclined arc towards the back of the knitting machine.
Here, the warp beams are arranged above the needle bar catered from the front tog the machine.
