Interlock Knit Fabric
The double-faced, no-curl premium knit. Identical on both sides, thick, stable, and smooth — the gold standard for polo shirts, hoodies, and structured sportswear in 40+ countries.
What Is Interlock Knit Fabric?
Interlock knit fabric is a premium double-knit textile where two layers of single jersey are knitted simultaneously on interlocking needle beds. The result is a fabric that looks identical on both sides, has no distinct front or back, and — critically — does not curl at cut edges.
Our range spans 100% cotton, cotton-polyester blends (65/35, 60/40), and polyester-spandex interlock (92/8, 88/12) — covering everything from soft babywear to performance polo shirts that hold embroidered logos flawlessly.
Every roll is tested for shrinkage control (<3%), pilling resistance (Grade 4+), dimensional stability, and GSM consistency before it leaves our facility.
Fabric Composition Options
From soft natural cotton to high-performance poly-spandex — choose the right interlock for your product.
GSM Range & Use Cases
Interlock sits in the mid-to-heavy weight range — its double-knit construction naturally produces a denser fabric.

14 ready-stock colors for cotton interlock. Polyester interlock available in white for sublimation or dyed to any Pantone shade.
Why Interlock Stands Apart
Properties unique to the double-knit construction that make interlock the premium choice.
No-Curl Edges
Unlike single jersey, interlock lies completely flat at cut edges — easier to sew, cleaner finished garments.
Double-Faced
Identical appearance on both sides — no wrong side, no need for lining or facing in most applications.
Dimensional Stability
Resists stretching and distortion during cutting and sewing — holds shape through production and wear.
Fully Opaque
Dense double-layer construction eliminates see-through — no undershirts needed, even in white.
Smooth Hand Feel
Even, regular surface with a soft, premium hand — feels more expensive than single jersey at the same price point.
Embroidery-Ready
Stable surface holds stitches without puckering — the preferred knit for logo embroidery on polo shirts.
Shape Retention
Maintains garment structure wash after wash — collars stay upright, hems stay flat, silhouettes hold.
Insulating Air Pocket
Double-layer trap creates a micro air pocket between layers — naturally warmer than single knits.
What It's Used For
Interlock shines in structured, premium garments where stability and presentation matter.
Interlock vs. Single Jersey
The most common question we get. Here's an honest side-by-side so you pick the right knit for every product.
| Property | Interlock | Single Jersey |
|---|---|---|
| Knit Structure | Double-knit (2 layers) Premium | Single-knit (1 layer) |
| Edge Curling | None Interlock | Curls at cut edges |
| Face / Back | Identical both sides Interlock | Distinct V-face / purl back |
| Thickness | Thicker, more substantial Interlock | Thinner, lighter |
| Opacity | Fully opaque Interlock | Semi-transparent in light colors |
| Stretch | Moderate (20–25%) | Higher (30–40%) Jersey |
| Embroidery Quality | Excellent — stable surface Interlock | Can pucker on light weights |
| Breathability | Good | Better airflow Jersey |
| Cost Per Meter | 20–30% higher | More affordable Jersey |
| Drape | Structured, holds shape Interlock | Softer, more fluid drape |
| Best For | Polos, hoodies, uniforms | T-shirts, leggings, base layers |
Honest Assessment
- No curl at cut edges — dramatically easier cutting and sewing
- Identical on both sides — no wrong side, reversible potential
- Fully opaque — no transparency even in white and light shades
- Excellent embroidery base — stable surface prevents puckering
- Premium, substantial hand feel that elevates perceived garment quality
- Superior shape retention — garments hold structure wash after wash
- Natural insulation from double-layer air pocket construction
- Works beautifully in both cotton (natural) and polyester (performance) versions
- 20–30% more expensive than single jersey per meter
- Heavier and less breathable — not ideal for hot-weather base layers
- Lower stretch recovery than jersey-spandex blends
- Cotton interlock cannot be sublimated — limited to screen/DTG/embroidery
- Requires more yarn per meter — higher raw material consumption
- Takes slightly longer to dry than single-knit fabrics
Best Methods for Interlock
The right printing method depends on your fabric composition — cotton and polyester interlock have different requirements.
Embroidery
Interlock's stable, dense surface is the gold standard for embroidered logos — especially on polo shirts. Stitches sit cleanly without puckering or distortion.
Sublimation Printing
For 100% polyester or poly-spandex interlock — full all-over printing with unlimited colors. The double-knit structure absorbs dye evenly on both sides.
Screen Printing
Works on both cotton and polyester interlock. The stable surface prevents ink migration and ensures crisp edges. Ideal for bold logos and repeat-order designs.
Make It Yours
Every aspect of the interlock — from yarn to finish — can be tailored to your brand.
Yarn Count
20s, 24s, 30s, 40s — finer yarns for lighter weight, coarser for heavier feel.
Blend Ratio
Any cotton/poly ratio or poly/spandex blend — tailored to your needs.
GSM Target
Precision-controlled weight from 160–340 GSM for your garment category.
Surface Finish
Smooth face, brushed back, peached, or bio-polished for ultra-soft feel.
Shrinkage Control
Pre-shrunk and compacted to guarantee <3% residual shrinkage.
Branding
Woven labels, heat-transfer tags, custom hang tags — all integrated.
