Interlock stitches create a stretchy seam in knit fabrics, while overlock stitches secure fabric edges to prevent fraying and create a clean finish.
Interlock vs. Overlock

Key Differences

Interlock stitching is a technique used primarily in knitting to produce a double-layered fabric that resembles two pieces of single jersey fabric knitted together. This method results in a fabric that is thicker, with a smooth surface on both sides, making it ideal for high-quality knitwear. Overlock, on the other hand, is a type of stitch used to seam or edge fabric, commonly found in serging. It wraps thread over the fabric edge, cutting and enclosing the fabric edge within the thread to prevent fraying.

While interlock stitches provide a stretchy and comfortable seam ideal for knit garments, ensuring durability and elasticity, overlock stitches are designed to create a clean, finished edge on fabric. Overlock is versatile, working well with a wide range of materials, including both knit and woven fabrics, and is especially useful in preventing the unraveling of fabric edges.

Interlock is characterized by its use of two sets of needles, where stitches interlock with each other, creating a double-faced fabric. This technique allows for a more stable and durable fabric structure, offering good stretch and recovery. Conversely, overlock stitches use one or two needles but with loopers that create an edge finish that is both secure and stretchable, depending on the thread and stitch settings used.

The interlock stitch provides a neat appearance on both sides of the fabric, making it suitable for garments that require a clean look inside and out, such as T-shirts and baby clothes. Overlock stitches, while primarily functional in finishing edges and seams, can also be decorative, depending on the thread color and stitch type used.

In terms of applications, interlock fabric is preferred for high-end, comfortable clothing items where the feel and appearance of both sides of the fabric are important. Overlock stitching, meanwhile, is indispensable in the garment industry for edging, hemming, and seaming, providing a professional finish to a wide array of clothing items.
