Interlock Knit Fabric Directory

How Interlock Is Knitted

Interlock is a double knit, produced on a circular knitting machine with two sets of needles working together. The structure is two 1x1 rib fabrics knitted into each other - interlocked - so the wales of one face sit directly behind the wales of the other. The result is a cloth that is smooth on both sides, with no visible difference between face and back, and noticeably thicker, warmer and more stable than a single jersey of the same yarn. Where jersey curls at the edges and stretches out of shape, interlock lies flat, cuts cleanly and keeps the shape it was sewn into, which is why garment makers reach for it when a knit has to behave almost like a woven.

The yarn decides the character of the cloth. Cotton interlock is the classic: soft, breathable, opaque and kind against skin, used for T-shirts, polo shirts, underwear, nightwear and children's garments, where the smooth double face and the lack of curling make sewing and wearing easy. Polyester and blended interlocks serve sportswear and uniforms, where moisture handling, easy care and colour fastness matter more than natural-fibre softness. A touch of elastane turns interlock into a firm stretch cloth for dresses and fitted tops. Around this directory, interlock sits beside Jersey - see also our Jersey section - and the wider Fabric Mill Directory indexes the whole section by fabric type.

Weights, Uses and Specifying Interlock

Interlock is specified by fibre, weight, width and finish. Weights run from light cloths for underwear and T-shirts to heavy cloths for sweatshirts, jackets and structured dresses; the weight, usually quoted in grams per square metre, is the single most useful number when comparing two mills' interlock, because two cloths of the same fibre at different weights are effectively different fabrics. Width matters for cutting economy, and finishes - anti-pilling, moisture management, antibacterial, pre-shrunk - should be named in the enquiry rather than assumed. Because interlock is reversible, it also suits garments where the inside shows: hoods, cuffs, wraps and unlined jackets all benefit from a cloth with two good faces.

The uses list follows from the structure: T-shirts and polo shirts that keep a clean edge, dresses and skirts that need body without stiffness, underwear and sleepwear that need opacity and softness, baby and children's garments that need a smooth, non-curling cloth, and team and work uniforms that need a knit that survives repeated washing. When enquiring of a mill below, state fibre, weight, width, colour and finish - those five facts are a complete interlock specification, and a quotation given without them is not yet a price for the cloth you need. Judge each mill by the knits its own profile says it produces regularly: interlock is a specialist double knit, and a knitting mill tooled for it will name its gauges and weight range plainly.
