Our fabric library includes 977 double knit options. Contact us for more compositions, weights and colours for your collection.
Double knit fabric is knitted on two sets of needles at once, a cylinder and a dial, so two layers of loops are linked into a single, thicker fabric. Compared with single jersey, a double knit is more stable, more opaque and lies flat at cut edges. Double knit is a family rather than one fabric: interlock, rib, Ponte Roma, scuba and many double-knit jacquards all belong to it. With 977 qualities, it is the second-largest structure in our library after single jersey. Most weigh 220–310 GSM; cotton/polyester is the biggest blend for sweatwear and trousers, 100% cotton leads for T-shirts, and nylon/spandex serves activewear. A double knit uses more yarn than single jersey, so it is warmer and drapes less, which can feel heavy in very light summer tops.
Cotton/polyester blends lead our double knit range; pure cotton serves tees, and stretch blends serve fitted and active pieces.
| Fabric type | Fabric examples | Apparel applications |
|---|---|---|
| Cotton/polyester and cotton/polyester/spandex | 250–330 GSM, such as KF1105 (60% cotton / 40% polyester) at 310 GSM | Sweatshirts, joggers, casual trousers and knit jackets |
| 100% cotton and cotton/spandex | 180–260 GSM, such as M010# (100% cotton) at 180 GSM and SM2168 (95% cotton / 5% spandex) at 230 GSM | T-shirts, dresses and polo shirts |
| Viscose, modal and acrylic blends | 230–300 GSM, such as P4387 (40% acrylic / 39% modal / 12% cashmere protein fibre / 6% wool / 3% spandex) at 280 GSM | Base layers, thermal tops and knit dresses |
| Nylon/spandex and polyester/spandex | 175–280 GSM, such as KF2117 (75% nylon / 25% spandex) at 230 GSM | Yoga wear, leggings and sports bras |

Xiwen Zhang, our co-founder and CEO, recommends these double knit weights and blends for the garments where a stable, opaque knit makes production easier, drawing on our knit fabric experience since 2009.

WHERE DOUBLE KNIT LEADS
Choose 260–330 GSM cotton/polyester double knit for sweatshirts, sweatpants and streetwear tops. Sweatwear is the largest use for double knit in our library, and the flat-lying edges make cuffs, hems and pockets easier to sew neatly.

A STABLE LEG THAT KEEPS ITS LINE
250–320 GSM double knit works well for casual trousers and joggers. A little spandex helps the knees and seat recover, and the opaque structure suits light colours.

OPAQUE, SMOOTH, NO CURL
For a heavier, more opaque tee than single jersey, start with 190–260 GSM cotton double knit. Hems and sleeves lie flat after cutting, and the dense face gives a structured, boxy T-shirt a clean finish.

BODY WITHOUT LINING
Choose 210–300 GSM double knit for shift, T-shirt and skater dresses. The two-layer structure is opaque enough for most dresses without a lining, and it holds a defined skirt shape better than single jersey.

SHORTS THAT KEEP THEIR EDGES
For casual and sweat shorts, start with 240–300 GSM double knit. The stable structure keeps leg openings and pocket edges from rolling, which matters on shorter hems.

STRUCTURE FROM THE KNIT ITSELF
270–340 GSM double knit suits knit blazers, overshirts and zip jackets. It gives fronts and collars enough body to stand without heavy interlining, while staying softer and easier to wear than a woven jacket.

A SMOOTH POLO ALTERNATIVE
For polo shirts with a smooth face rather than pique texture, choose 200–290 GSM double knit. The structure keeps collars and plackets neat, which suits uniform and business-casual polos.
No. Interlock is one type of double knit. Rib, Ponte Roma, scuba and many double-knit jacquards are also double knits. They share two needle sets but differ in surface, stretch and body.
Choose single jersey, mostly 165–230 GSM in our library, for a lighter, more fluid tee. Choose 190–260 GSM double knit for a heavier, more opaque tee whose hems lie flat.
Weight and recovery. Most double knit trouser qualities in our library weigh 250–320 GSM; a cotton/polyester/spandex blend helps knees and seat recover. Check recovery on a sample after sitting and bending.
For cotton/polyester double knit at 250–330 GSM, set shrinkage in length and width and pilling, the two lines sweatshirts and joggers are judged on, and write the drying method next to any shrinkage limit. Nylon/spandex double knit for yoga wear needs perspiration and light fastness instead.
