シングルジャージー vs インターロック vs ピケ：適切な編組織の選び方

When buyers talk about knit fabric, the conversation usually starts with fiber and weight. But the knit structure — how the loops are formed and interlocked — is just as decisive. Two fabrics with identical cotton content and identical GSM can feel and perform completely differently depending on whether they are single jersey, interlock or piqué.

This guide explains the three structures that cover most cut-and-sew knitwear, and how to choose between them.

Why Knit Structure Matters

Knit fabric is made by interlooping yarn. The way those loops are arranged determines stretch, stability, drape, breathability, curl and how the fabric takes printing and embroidery. Get the structure wrong and you may find your T-shirt twists after washing, your polo loses its collar shape, or your print cracks.

Structure is not a detail to leave to the mill — it is a design decision you should specify.

Single Jersey: The Everyday Standard

The most common knit in apparel. Single jersey has a smooth face and a textured, looped back. It is produced on a single set of needles, which makes it light, stretchy and economical.

Characteristics

Best for

T-shirts, lightweight tops, dresses, underwear, sleepwear and summer basics.

Watch out for

Single jersey can **curl at the edges** — a natural consequence of its structure — which is why hems and necklines need rib or binding to control it. It also has a tendency to twist slightly after washing if the yarn tension is not properly controlled.

Interlock: The Stable Two-Faced Knit

Interlock uses two sets of needles to produce a fabric with the same smooth appearance on both sides. It is denser, more stable and less curly than single jersey.

Characteristics

Best for

Premium T-shirts, polo shirts, dresses, childrenswear and any garment where a clean, stable, reversible fabric matters. Interlock is often chosen when a brand wants a more substantial, less transparent tee.

Why buyers choose it

Interlock resists curling, holds shape through repeated washing, and delivers a more premium hand than single jersey at a similar fiber content. It is a strong upgrade spec for higher price-point basics.

Piqué: The Textured Polo Workhorse

Piqué has a textured, waffle-like surface created by a knit-woven structure with tuck stitches. It is most associated with polo shirts, but also appears in premium tees and sportswear.

Characteristics

Best for

Polo shirts, golf and sportswear, corporate uniforms and any application needing a crisp, structured look that breathes well.

Watch out for

Piqué's texture makes fine print detail harder to reproduce than on a smooth jersey face. It is better suited to embroidery, patches or bold graphics.

Head-to-Head Summary

How Structure Interacts with Fiber and Weight

Structure does not act alone. The same piqué in cotton-polyester behaves differently from piqué in 100% cotton. Weight also shifts the outcome: a 180 gsm interlock feels quite different from a 280 gsm interlock. When specifying, always state all three:

Skipping any one of these is the fastest route to a sample that disappoints.

Printing and Decoration Considerations

Quality Checkpoints Before Bulk

Whatever structure you choose, verify:

Conclusion

Single jersey, interlock and piqué are not interchangeable — each solves a different problem. Single jersey wins on lightness, softness and cost; interlock wins on stability and premium hand-feel; piqué wins on structure and breathability for polos and sportswear. Specify structure alongside fiber and GSM, and validate with shrinkage and spirality testing before you commit to bulk.
