Working Principle of Circular Knitting Machine

Circular knitting machine is the first choice for knitted fabric manufacturers. It is widely used throughout the knitting industry to produce fabric for its productivity and user friendliness. It has been designed and manufactured for mass production of knitted fabrics. Huge range of diameter (12 inch to 60 inch) according to manufactures requirement that is perfect for manufacturing outerwear and under wear. In this article I will explain that how to yarn pass through circular knitting machine. I have also discussed about different parts of circular knitting machine with their functions.

Working principle of circular knitting machine:
Working process of circular knitting machine is comparatively easy from other knitting machine. I have explained it with simple way. If you see the below figures with concentrately then you will know how to circular knitting machine making fabric from yarn. For knowing clearly I have given short description of all parts of circular machine with their functions.

Parts of circular knitting machine and their function:
Working principle of circular knitting is done by the following parts:

Creel: Which is used to place the yarn cone, from where the yarn is supplied to m/c, through pipe. 

Yarn Guide: Which is used to guide the yarn, Yarn guide is necessary for maintaining proper tension on yarn during kitting.

Yarn Tensioner: Yarn tensioner is requiring to proper gripping of yarn by needle.

Feeder: Feeder is directly related to the production. e.g. if no of feeder is high then production will be high and vice versa.

Cylinder: Cylinder is an important part of knitting m/c through which needles are set. During selection of knitting m/c for specific types of knitting cylinder gauge is an important parameter.

Needle: The main part of knitting m/c is needle, without needle it is impossible to knit garments. In knitting m/c there are many types of needle may be used, like latch needle, bearded needle, compound needle but latch needle are very popular in knitting.

Cam box: Cam box is used to hold the cam according to the fabric design. Knitting cams are arranged according to the design, e.g. arrangement of knit, tuck & miss cam.

Sinker: Sinker is essential for knitting garments. Sinker is used to hold & support the thread during the loop formation. In knitting different shape of sinker is used.

VDQ Pulley: VDQ pulley is very important in maintaining proper stitch length.

Base plate: Base plate is circular shaped body, on which cylinder is situated.

Take-up roller:
Take-up roller is used to take the knitted fabric from m/c, which also maintains the proper tension on knitted fabric.

Body: Body of m/c is the hole area of m/c, through which base plate, cylinder consist. 

Auto Stopper: Auto stopper is used to automatically stop the m/c if any fault is occurred.
