Double Knit Fabric: Structure, Benefits, and Fashion Applications
🔍 What Is Double Knit Fabric?
Double knit is a type of weft-knitted fabric constructed using two sets of needles that knit two layers of fabric simultaneously. Unlike single knit, which creates one layer, double knitting results in a double-faced fabric—meaning both sides look identical.
This structure provides extra durability, excellent stability, and resistance to sagging or distortion. Because of these properties, double knit is widely used in structured knitwear, cuffs, hems, waistbands, and even tailored knit garments.
🧵 Key Characteristics of Double Knit
| Property | Description |
|---|---|
| Structure | Two layers of loops interlocked to form a stable knit |
| Face Appearance | Both sides look the same (double-faced) |
| Stretch | Moderate elasticity, more stable than single knits |
| Edge Behavior | Cut edges do not curl, making it easier to sew |
| Thickness | Thicker than single jersey; offers better warmth and coverage |
| Drape | More structured, with less fluid drape than lightweight knits |
🧷 Sewing and Handling Advantages
In a sewing workshop, double knit is especially appreciated for its clean-cut edges. Unlike single jersey, it does not curl along the cut lines. This means there’s no need for extensive stabilizing, making it easier to cut and stitch, especially in garment mass production.
Additionally, the fabric holds its shape over time. It is ideal for structured silhouettes, such as A-line dresses, bodycon skirts, tailored tops, and jackets made from knit material.
👕 Common Fashion Applications
Double knit is used in a wide range of garments that require a balance of comfort, structure, and durability:
- Sweater hems and sleeve cuffs
- Pencil skirts and tailored knit trousers
- Blazers and knit jackets
- Winter dresses
- Uniforms and athletic apparel
Its smooth finish and uniform appearance make it ideal for professional and polished garments.
🛍️ Fabric Comparison: Double Knit vs Single Knit
| Feature | Single Knit | Double Knit |
|---|---|---|
| Curling at Edges | Yes | No |
| Appearance (2 sides) | Different front and back | Same on both sides |
| Stability | Stretchy, less stable | Highly stable |
| Drape | Lightweight, fluid | Structured, heavier |
| Applications | T-shirts, casual wear | Dresses, blazers, skirts |
🧶 Tips for Working With Double Knit
- Use a ballpoint needle when sewing to avoid damaging the knit structure.
- A serger or overlock machine works well for clean seam finishes.
- Pre-wash the fabric to account for minimal shrinkage.
- Because the fabric is thicker, consider adjusting needle tension and presser foot pressure.
