Jersey, interlock and rib describe knit structures rather than fibre names. A cotton composition does not tell you which structure is used, and the word jersey may describe fabric rather than a team uniform. Knowing the distinction makes fabric specifications easier to compare and reduces misunderstandings between buyers and manufacturers.
What the terms identify
Single jersey is a common T-shirt knit. Rib uses alternating knit and purl columns, while interlock combines two related rib structures into a double-knit construction. CottonWorks explains the construction differences. These names describe how loops are arranged, not a complete recipe for comfort or durability.
Why a collar may use a different structure
A body fabric and a neck trim can have different jobs. Rib is often used for collars because its construction allows extension. The finished collar still depends on its material, dimensions and attachment. A fabric name alone does not establish whether a neckline will return neatly after repeated wear, so inspect the actual trim and sample.
Compare like with like
If two suppliers quote jersey, confirm whether they mean the same construction as well as matching composition and weight. Interlock should not automatically be labelled superior; it is a different structure with its own appearance and handling. Judge it against the garment’s purpose, decoration and target fit rather than an assumed hierarchy.
Turn fabric terminology into sample questions
Request a swatch that is clearly identified with the quotation and ask which material will be used for the body, neck and any contrast panels. Review both faces and the assembled garment. If a sample differs from the proposed production fabric, record that limitation before approval so the wrong swatch does not become the reference.
Practical checklist
- Separate knit structure from fibre composition.
- Identify body and collar materials.
- Compare both fabric faces and the assembled shirt.
- Keep swatch references tied to the quotation.
