The Ultimate Guide to Double Jersey Circular Knitting Machines
In the dynamic world of textile manufacturing, efficiency and versatility are paramount. Among the most critical pieces of equipment for producing high-quality fabrics is the Double Jersey Circular Knitting Machine. This guide delves deep into its workings, benefits, and applications, providing a comprehensive resource for industry professionals and enthusiasts alike.
What is a Double Jersey Circular Knitting Machine?
A Double Jersey Circular Knitting Machine is a specialized industrial knitting machine designed to produce double-knit fabrics. Unlike single jersey machines that create fabric with a distinct front and back, double jersey machines knit two layers of fabric simultaneously, interlocking them to form a single, stable, and often reversible material. This process results in fabrics that are thicker, less prone to curling, and more dimensionally stable.
Core Mechanism and Fabric Structure
The magic lies in its cylinder and dial setup. The machine features a circular needle bed (cylinder) and a dial with radial slots. Two sets of needles—cylinder needles and dial needles—work in tandem. Yarns are fed to both sets, creating two distinct layers of loops that are interconnected during the knitting process. This creates the characteristic double-knit structure, renowned for its excellent recovery and comfort.
Key Features and Advantages
Why choose a double jersey machine? The advantages are significant for bulk production.
High Production Speed & Efficiency: These machines operate at high RPMs, producing large volumes of tubular fabric continuously, which drastically reduces production time and cost per unit.
Superior Fabric Quality: They produce fabrics with excellent elasticity, shape retention, and a smooth finish on both sides. The double-layer construction adds warmth and opacity.
Remarkable Versatility: From basic interlock and rib fabrics to more complex jacquard patterns and pique structures, these machines can handle a wide array of designs.

Reduced Material Curling: The balanced structure inherently resists the curling edges common in single jersey fabrics, simplifying subsequent cutting and sewing processes.
Common Applications in the Textile Industry
The fabrics produced are ubiquitous in our daily lives. Primary applications include:
Apparel: T-shirts, polo shirts, dresses, leggings, sportswear, and casual wear.
Home Textiles: High-quality bed linens, upholstery fabrics, and technical textiles.
Industrial Uses: Used in products requiring durable, stretchable fabric layers.
Frequently Asked Questions (FAQ)
What is the difference between single jersey and double jersey?
Single jersey is a single layer of knit fabric, lighter and curls at the edges. Double jersey is two interlocked layers, thicker, stable, and often reversible.
What types of yarn are best suited?
They are highly adaptable. Common choices include cotton, polyester, viscose, wool, and various blends. The yarn count should be compatible with the machine’s gauge.
How do I maintain a circular knitting machine?
Regular cleaning, lubrication, needle
