Circular Knitting vs. Flat Knitting: Which Process Does Your Product Need?

Short answer: circular knitting makes fabric in a continuous tube and is used for T-shirts, hoodies and most apparel knits. Flat knitting makes shaped panels or fully-fashioned pieces and is used for sweaters, cardigans, scarves and knitted hats. Choose by product type: if you are making a cut-and-sew garment from fabric, you want circular knitting; if you are making a shaped knitwear piece from yarn, you want flat knitting.

How Circular Knitting Works

Circular knitting machines knit in a continuous spiral, producing a tube of fabric. The tube is either used as-is (tubular fabric) or slit open into flat width. Because the machine knits continuously, it is fast and economical at volume.

How Flat Knitting Works

Flat knitting machines knit back and forth in a flat bed, producing panels or whole garment pieces. Modern computerized flat knitting can knit shaped panels, jacquard patterns and even complete garments with minimal cutting.

Which Process for Which Product

Can You Use Both in One Product?

Yes, and many products do. A hoodie is a good example: the body and sleeves are cut from circular-knitted fleece, while the cuffs, hem band and sometimes the collar are flat-knitted rib. A sweater may be flat-knitted throughout but use circular-knitted rib for the bottom hem.

This matters when choosing a supplier: a mill with both circular and flat knitting can produce a complete garment without sending parts to a third party.

What Buyers Should Specify

Conclusion

Circular and flat knitting are not competing methods — they make different products. Circular knitting produces the fabric for cut-and-sew apparel; flat knitting produces shaped knitwear and accessories. Know which your product needs, and prefer a manufacturer that runs both, so one partner can cover a full knitwear range.
