Decoding the Foundation of Circular Knitting
Choosing between a single jersey and a double jersey circular knitting machine is the first and most decisive step when setting up or expanding a knitting mill. The two machine families produce fundamentally different fabric structures, so the right pick depends entirely on your target products.
In modern textile production, efficiency, fabric quality, and versatility are paramount. LEADSFON delivers premium, world-class machinery designed to address these demands, helping manufacturers navigate the complexities of machine selection with precision-engineered solutions.
Single Jersey Circular Knitting Machines
High speed, efficiency, and lightweight versatility for mass-market demand.
Technical Mechanism
Single jersey (single-sided) machines utilize a single cylinder needle bed. They knit one set of needles to yield lightweight, highly extensible fabrics.
Key Applications
Perfect for T-shirts, underwear, casual sportswear, and light summer apparel. Covers over 70% of basic global knitwear needs.
LEADSFON Models
DJI3.2/2.8 (3.2/2.8 feeds/inch, exceptional fabric smoothness)and DJR1.8 rib machine for high-elasticity structures. Feeder can be customized
Sinkerless Innovation: The SL3.0 Edge
In traditional single jersey machines, the stitch is constructed with the moving sinkers(through a special settling sinker design and model). In the SL3.0 machine, the stitch is formed at a stationary point. No more vertical lines, no more elastane misplating defects, no more fabric peeling. Ideal solution for very fine gauges. This technology is ideal for high-end swimwear and sensitive activewear fabrics.
Double Jersey Circular Knitting Machines
Structured, reversible, and premium fabrics with advanced mechanical stability.
Technical Mechanism
Double jersey machines feature two needle beds (dial and cylinder). The interaction of these two sets of needles produces thick, non-curling structures.
Key Applications
Creates stable, reversible fabrics such as interlock, rib, French terry, and spacer fabrics for polo shirts, leggings, and uniforms.

Dial and Cylinder Alignment: The Heart of Double Jersey
Operating a double jersey machine requires advanced synchronization between the dial and cylinder cams. LEADSFON's DJI and DJR series utilize high-precision gearing systems engineered to European standards, ensuring that timing issues are minimized even at high-speed continuous runs. This yields flawless interlock and rib structures.
Direct Comparison Matrix
A side-by-side technical evaluation to guide your investment.
| Features / Parameters | Single Jersey Machine | Double Jersey Machine |
|---|---|---|
| Needle Beds | 1 Bed (Cylinder only) | 2 Beds (Dial & Cylinder) |
| Fabric Output | Single-sided (curls at edges) | Double-sided / Reversible (lies flat) |
| Common Fabric Types | Jersey, Pique, Fleece, Sinkerless knit | Rib, Interlock, Spacer, Scuba |
| Production Speed | Higher (Higher RPM) | Moderate (Complex mechanism) |
| Investment Cost | Lower initial cost, simpler setup | Higher initial cost, premium output |
| Maintenance & Skill | Standard mechanical maintenance | High skill level (Gearing & timing) |
Key Decision Factors to Consider
1. Product Range
If your factory focuses on high-volume basic wear like T-shirts and activewear, Single Jersey covers 70%+ of your needs. Choose Double Jersey to unlock structured garments, winter apparel, and premium athleisure.
2. Budget & Space
Single jersey machines are mechanically simpler, cheaper to purchase, and require less operational footprint. Double jersey represents a larger capital investment but yields higher profit-margin fabrics.
3. Labor Skill
Double jersey setups demand experienced technicians to manage the precise alignment of dial and cylinder needles. Single jersey machines are generally easier to set up and troubleshoot.
