The needle is the most fundamental part of the machine, it’s the heart of the knitting without the needle nothing is possible it helps in intermeshing the loop with the new loop, each needle adds a particular loop in that particular column.
This weft knitting needle is very important that it should survive multiple cycles.Because, when we are creating fabric on the machine, it has many courses so the needle has continuously operated because of this the first requirement of the needle is it should be highly strong. Fabric is hanging so each needle carrying the weight of the fabric may be the chance that the needle has to carry a high load because of which it should be stronger, so that can’t break from the top part.
The other thing is it should be highly tougher, the cam jacket is interact with the butt of the needle, there is a sharp force which is applied on this needle So that shock or that impact has to be absorbed by this needle so the needle has to be highly tougher. So the material which is used for this needle should have sufficient toughness.
The third thing which is primarily important for this needle is the smooth surface because the needle interacts with the yarn and the yarn has to slide, for example, the loops have to slide on this surface of the needle rough, there is a high tension variation in the yarn can happen because of that the yarn break so the surface of the needle has to kept very smooth.
