Circular Knitting Machines Overview

Structure and Operation

A circular knitting machine is very important in making textiles. It has needles set in a circle to knit fabric into a tube. Many parts work together inside the machine. Yarn feeding systems control how much yarn goes in and keep it tight. Creels hold yarn bobbins and help the yarn stay smooth and clean. The machine frame holds everything up and helps it work well. The fabric take down mechanism moves finished fabric away from the needles and helps split up garments. Some machines can even make 3D shapes for socks or clothes. Control mechanisms let you change speed, pattern, and fabric size. These machines can do both tubular and open-width knitting, so you can make many fabric panels at once.

There are two main types of circular knitting machines. They are single jersey and double jersey. Each type makes fabric in its own way and is used for different jobs in textiles.

Industry Uses

Circular knitting machines are used in many industries. The apparel industry uses them the most because people want soft and nice clothes. Home textiles, like sheets and curtains, also use these machines, but not as much as clothing. Some factories use them to make special filters for industry. More people want seamless and soft clothes, so the market for these machines is growing.

• The apparel industry uses the most circular knitting machines.

• Home textiles and industrial filtration use them less than apparel.

• More people want seamless and comfy clothes, so the market grows.

Single Jersey Circular Knitting Machine

Needle Arrangement

A single jersey circular knitting machine has a special needle setup. The needles are placed inside a cylinder. Cams can make the needles knit, tuck, or miss. This lets you make different patterns like plain and pique. Cylinder cams help you change styles fast.

Working Principle

This machine uses one cylinder with needles. Yarn comes from cones and goes through guides to the needles. The cam system moves the needles up and down to make loops. The cylinder turns and links the loops side by side. This makes tube-shaped fabric.

• You get plain fabric with a clear front and back.

• The front side has straight lines going up and down.

• The back side has lines going side to side.

• The fabric can stretch in all directions and hangs nicely.

• You can use this machine for simple clothes and sportswear.

Features

Here is a table that shows the main features of a single jersey circular knitting machine:

Tip: If you want soft, stretchy, and light fabrics for daily wear, a single jersey circular knitting machine is a great pick.

Double Jersey Circular Knitting Machines

Needle Setup

A double jersey circular knitting machine has two sets of needles. The needles are placed in a "V" shape. This helps make loops at the same time. A single machine only has one set of needles. The double setup makes fabric thicker and stronger. You can also make patterns on both sides.

How It Works

This machine uses both needle sets to loop yarn. You can pick synchronized timing or delayed timing. Synchronized timing means needles make loops together. Delayed timing means needles work with a small gap. The timing changes how tight the yarn is and how big the loops are.

You can change these settings to control how thick and soft the fabric is.

Features

Double jersey circular knitting machines have many cool features. They use computers to pick needles for special patterns. These machines work with many yarn types, like cotton and synthetics. You can switch colors fast with a striper device.

Advantages

There are many good things about this machine:

• You can make thick, warm fabric that stays flat.

• You can make designs with different colors on each side.

• You can knit two layers at once for special needs.

• You can use many yarn types for more options.

• You can make fabric fast and with good quality.

Disadvantages

There are some problems too:

• This machine is slower than a single machine.

• You need more skill to use and fix it.

• It costs more to buy and repair.

• You cannot make very thin or light fabrics.

Fabric Types

You can make many kinds of fabric with this machine. Here are some examples:

• Athleisure and sportswear, like leggings and sports bras made from polyester and spandex.

• Home textiles, such as blankets and cushion covers.

• Sportswear and activewear for comfort and strength.

• Special fabrics for medical or factory use.

Tip: If you want thick, strong fabric with patterns on both sides, pick a double jersey circular knitting machine.

Comparing Circular Knitting Machines

Needle Design

There is a big difference in how the needles work. The single jersey machine has one set of needles. These needles move around in a circle. They make fabric with only one side. The double jersey machine has two sets of needles. Both sets work together at the same time. They knit the front and back of the fabric at once. This makes the fabric thicker and stronger.

Tip: If you want patterns on both sides, use a double jersey machine.

Fabric Structure

The fabric changes based on the machine you pick. A single jersey machine uses one bed of needles. It makes plain, rib, and Lacoste fabrics. These fabrics are light and stretchy. They are good for T-shirts and sportswear. A double jersey machine uses two beds of needles. It can make interlock and moss stitch fabrics. These fabrics are thicker and heavier. They also stretch more and shrink more in width. Double jersey machines can make two layers at the same time. This gives you more choices for design and strength.

• Changing yarn count and stitch length changes the fabric.

• You can make the fabric softer or thicker by adjusting settings.

• Both machines let you make fabric with different warmth and air flow. You can pick the best type for your needs.

Production Speed

These machines work at different speeds. The single jersey machine is faster. It can make lots of fabric quickly. This is good for big orders of simple clothes. The double jersey machine is slower. It takes more time to make thick or fancy fabrics. The extra needles and careful control slow it down. If you want to work fast, pick the single jersey machine.

Note: If you need special or thick fabrics, you may have to wait longer.

Versatility

Both machines can do many jobs, but the double jersey machine does more. You can make tubes like sleeves and socks. You can also make coats, suits, stockings, baby clothes, and sweaters. The double jersey machine works with many yarns and patterns. You can make fabric that looks good on both sides or has two layers. The single jersey machine is best for simple things like scarves, hats, and T-shirts. You can change patterns fast, but you cannot make thick or double-sided fabric.

• Double bed machines help you make many things for different uses.

• Circular knitting machines let you make lots of items easily.

• Pick the machine that fits your design and job needs.

Tip: Think about what you want to make before picking a machine. The right choice helps you get the best results for your project.

Choosing the Right Circular Knitting Machine

Key Factors

When you choose a circular knitting machine, you need to think about several important factors. These factors help you match the machine to your production needs and fabric goals.

• Gauge: The gauge tells you how many needles fit in one inch. A finer gauge makes lightweight fabrics. A coarser gauge creates thicker materials. You should pick the gauge based on the type of fabric you want to produce.

• Speed and Productivity: Some machines can run at speeds up to 1,500 RPM. Higher speeds help you make more fabric in less time. This can lower your labor costs and help you meet big orders.

• Yarn Compatibility: Machines with automatic yarn feeding and tension control give you better knit quality. These features help you avoid defects and keep your fabric smooth.

• Fabric Type: Single jersey machines use one set of latch needles. They work fast and let you change yarns and colors easily. You can use them for soft, stretchy fabrics like T-shirts and sportswear. Double jersey machines have two sets of needles. They make thicker, more stable fabrics. These are good for sweaters, jackets, and other outerwear.

Tip: Always match the machine’s features to the fabric you want to make. This helps you get the best results and avoid waste.

Now you know the main ways these machines are different. Single machines make fabric faster and are good for simple jobs. Double machines make thicker fabric and can do more things. When picking a machine, think about how fast it works, how well it runs, what kinds of fabric it can make, and how much money it saves:

You should talk to experts if you need help with size or how much you want to make. Getting advice helps you pick the best machine for your needs and budget.
