What Makes Interlock Fabric Stand Apart

Double-Knit Construction for Superior Stability

Interlock fabric is produced using two interlocked jersey layers knitted simultaneously, creating a structure that is smooth and finished on both faces. Unlike single-knit jersey, interlock resists curling at the edges, making it far easier to cut and sew without fighting the fabric. This dimensional stability is why manufacturers consistently choose it for garments that need to hold their shape through repeated washing and wearing. If you work with cotton fabric regularly, interlock represents the premium tier of cotton knit construction.

Ideal Weight Range for Everyday Apparel Production

Our interlock fabric is available in weights ranging from 180gsm to 280gsm, covering everything from lightweight summer tees to structured loungewear and babywear. The mid-range weights around 220–240gsm are particularly popular for children's garments because the fabric is soft against sensitive skin yet resilient enough to withstand active wear. For brands exploring sustainable options, blends incorporating modal fabric or Lyocell Tencel fabric offer enhanced moisture-wicking and an even silkier hand feel within the interlock construction.

Versatile Applications Across Garment Categories

The smooth, pill-resistant surface of interlock makes it a go-to choice for T-shirts, fitted tops, infant bodysuits, leggings, and lightweight loungewear. Its natural two-way stretch provides comfortable ease of movement without the excessive give that can cause garments to lose their shape over time. Designers working on performance-adjacent casualwear often pair interlock with a small percentage of spandex fabric for added recovery, while those building a breathable fabric lineup will find cotton interlock performs exceptionally well in warm-weather collections.

Smooth, Stable Interlock Fabric Built for Production

Interlock fabric by the yard is one of the most dependable knit constructions available to apparel manufacturers, and our wholesale range is stocked to meet the demands of both small-batch brands and large-scale production runs. Every roll is consistent in weight, width, and hand feel — qualities that matter enormously when you are cutting multiple layers and expecting uniform results across thousands of units. Our cotton and cotton-blend interlock options are particularly well-suited to brands building core basics collections, where the fabric itself needs to communicate quality before a single stitch is sewn. For those sourcing across multiple fabric types, our cotton fabric category offers additional woven and knit options that complement interlock perfectly in a seasonal range.

Frequently Asked Questions

What is the difference between interlock and jersey fabric?

Jersey is a single-knit fabric with a distinct right and wrong side, and it tends to curl at the cut edges. Interlock is a double-knit construction where two layers of jersey are interlocked together, resulting in a fabric that looks identical on both sides and lies flat when cut. Interlock is also thicker, more stable, and generally smoother to the touch than standard jersey. For garments where clean edges and a refined finish matter — like babywear or fitted tees — interlock is the stronger choice.

Does interlock fabric stretch, and in which direction?

Interlock fabric stretches primarily in the width (crosswise), giving it a reliable two-way stretch that accommodates movement without excessive distortion. The lengthwise stretch is more limited compared to single-knit jersey, which actually contributes to better garment shape retention. If your design requires four-way stretch for athletic or form-fitting applications, look for interlock blended with elastane or spandex. Standard cotton interlock is best suited for garments where moderate stretch and structure are both desirable.

What GSM of interlock fabric should I choose for T-shirts versus babywear?

For adult T-shirts and casual tops, a weight of 180–220gsm strikes the right balance between drape and body. Babywear and infant garments benefit from 200–240gsm interlock because the slightly heavier weight adds softness and durability without feeling stiff against delicate skin. Heavier weights of 250–280gsm are better suited to loungewear, sweatshirts, or layering pieces where a more substantial hand feel is desired. When ordering wholesale, we recommend requesting swatches to confirm the weight and hand feel aligns with your end-use.

Is interlock fabric suitable for screen printing or heat transfer?

Yes, interlock's smooth, even surface makes it one of the better knit substrates for both screen printing and heat transfer vinyl applications. The tight knit structure minimizes ink bleed and provides a stable base that holds print registration well. Cotton and cotton-blend interlock fabrics are especially receptive to water-based and plastisol inks. Pre-washing the fabric before printing is strongly recommended to account for any residual shrinkage that could distort your artwork after the first wash.

What needle and stitch type should I use when sewing interlock fabric?

A ballpoint or stretch needle in size 75/11 or 90/14 is recommended for sewing interlock, as the rounded tip slides between the knit loops rather than piercing and potentially breaking them. A serger or overlock stitch is ideal for seams, though a narrow zigzag on a standard sewing machine also works well. If topstitching, a twin needle creates a professional, stretchy finish that mimics ready-to-wear construction. Avoid straight stitches alone, as they will pop under the lateral stress that interlock garments regularly experience.
