Plain knitting machine structure and process

Plain knitting machine are one of the most common types of knitting machines used in the textile industry. They are used to produce a wide range of knitted fabrics, including single jersey, double jersey, rib, and pique. Here are some of the key features of plain knitting machine process and structure:


The plain knitting process involves the interlocking of loops of yarn to form a fabric. The yarn is fed into the machine through a series of feeders and then passed through a series of needles that interlock the yarn to form a row of loops. The fabric is then moved down to the next row of needles, where the process is repeated.


The needles on a plain knitting machine are arranged in a straight line, with each needle having a hook at the end that interlocks with the yarn to form a loop. The needles are usually made of steel and can be either latch needles or spring needles. Latch needles have a latch mechanism that holds the yarn in place, while spring needles use a spring mechanism to hold the yarn.

Cam System:

The cam system controls the movement of the needles and determines the type of fabric that is produced. The cam system consists of a series of cams that are arranged in a circular pattern. As the cam system rotates, it moves the needles up and down, which determines the stitch type and pattern.

Yarn Feeders:

The yarn feeders on a plain knitting machine are used to feed the yarn into the machine. The yarn is usually fed from cones or bobbins and is guided through tension devices to ensure a consistent tension throughout the knitting process.

Fabric Take-Up:

The fabric take-up system on a plain knitting machine is used to move the knitted fabric down to the next row of needles. The take-up system usually consists of a series of rollers that grip the fabric and move it down to the next row of needles.

Knitting Speed:

The speed of a plain knitting machine can vary depending on the model and manufacturer. Some machines can knit up to 1,200 stitches per minute, while others can knit up to 2,000 stitches per minute.

Overall, plain knitting machines are versatile, efficient, and widely used in the textile industry. They can produce a wide range of fabrics, from light and airy to heavy and dense, and can be used to create a variety of designs and patterns.
There are several advantages of using a plain knitting machine:

What is the advantage plain knitting machine

Increased speed and productivity: Knitting machines can produce garments and textiles at a much faster rate than hand-knitting. This means that manufacturers can produce larger quantities of products in a shorter period of time.


Knitting machines can produce consistent stitches and tension, resulting in uniform and high-quality finished products. This is particularly important in industries where consistency is key, such as in the production of clothing and textiles.


Plain knitting machines can be used to produce a wide variety of fabrics and garments, including sweaters, scarves, hats, and blankets. This versatility allows manufacturers to produce a range of products without having to invest in multiple machines.

Cost savings:

While the initial investment in a knitting machine can be significant, the long-term cost savings can be significant. With a machine, manufacturers can produce more products with less labor, reducing the overall cost of production.


Many knitting machines can be programmed to create specific patterns and designs. This allows manufacturers to create custom products for their clients, which can be a valuable selling point in competitive markets.

Which fabric made by plain knitting machine

A plain knitting machine can be used to produce a variety of fabrics, including:


This is a lightweight, stretchy fabric that is commonly used for t-shirts, dresses, and other garments. Jersey fabric has a smooth surface and is comfortable to wear.

Rib knit:

Rib knit fabric has a distinctive pattern of raised vertical lines alternating with recessed horizontal lines. It is often used for cuffs, collars, and other parts of garments that need to be stretchy.


Interlock fabric is made up of two layers of knit fabric that are joined together, resulting in a thicker, more stable fabric. It is often used for baby clothes and other items that require a soft, comfortable fabric.

Purl knit:

Purl knit fabric has a bumpy, textured surface and is often used for sweaters and other garments that require a thicker, more substantial fabric.


Fleece fabric is made from synthetic fibers and has a soft, fluffy texture. It is often used for jackets, blankets, and other items that need to be warm and cozy.

These are just a few examples of the fabrics that can be made with a plain knitting machine. The type of fabric produced will depend on the yarn used, the stitch pattern, and other factors.
