Tricot fabric and interlock fabric can both be used in apparel sourcing, but they should not be treated as the same fabric. Tricot is usually selected when buyers need warp-knitted stability, smooth surface and controlled stretch. Interlock is often selected when buyers need a fuller handfeel, better body and a stable double-knit structure.
The right choice depends on garment use, GSM, width, stretch direction, opacity, finishing and the way the fabric will behave during cutting and sewing.
What is the main difference between tricot and interlock fabric?
Tricot fabric is a warp-knitted fabric. It is commonly used when a smooth surface, stable width and lighter construction are required. Interlock fabric is a weft-knitted double-knit structure, often used when buyers need a heavier handfeel, better surface stability and more body.
| Item | Tricot Fabric | Interlock Fabric |
|---|---|---|
| Knitting direction | Warp knitted | Weft knitted double-knit |
| Typical handfeel | Smooth, compact, sometimes sleek | Fuller, softer, more stable body |
| Common uses | Swimwear, lining, sportswear, light functional fabric | Sportswear, polo fabric, casual apparel, stable knit panels |
| Buyer focus | Width stability, stretch direction, opacity, finishing | GSM, surface stability, shrinkage, pilling, handfeel |
When should buyers choose tricot fabric?
Buyers should consider tricot fabric when the garment needs a smooth warp-knitted surface, controlled stretch and stable fabric behavior. It is often suitable for swimwear, beachwear, lining, dancewear, bags, outdoor textile parts and some sportswear panels.
Tricot can also be useful when the design needs a cleaner surface and less edge curling than some lighter weft-knitted structures. However, buyers still need to check opacity, stretch recovery and handfeel after finishing.
When is interlock fabric a better choice?
Interlock fabric is often a better route when the buyer needs more body, a stable surface and a fuller handfeel. It is commonly used in sportswear, uniforms, polo shirts, casual tops and some activewear styles that need a more structured knit.
For interlock fabric, GSM and finishing are important. A heavier interlock can feel stable but may reduce breathability. A lighter interlock may improve comfort but might not provide enough coverage for the final garment.
What should buyers check before sampling?
Before requesting samples, buyers should avoid asking only for a fabric name. The factory needs application, target GSM, width, handfeel, stretch direction, finishing and test requirements.
- Confirm whether the final garment needs warp-knitted or weft-knitted construction.
- Check GSM, usable width and shrinkage tolerance.
- Review handfeel, opacity and surface appearance on a physical sample.
- Confirm stretch direction and recovery if spandex is included.
- Test color fastness, pilling and washing stability before bulk production.
Factory recommendation for sourcing teams
If the buyer is choosing between tricot and interlock fabric, the most practical route is to send the target garment, reference sample and expected performance. A fabric that looks similar in photos can behave differently during cutting, sewing and wearing.
Changle Textile can support both tricot and interlock fabric development by composition, GSM, width, color, handfeel, stretch and finishing requirements.
FAQ
Is tricot fabric always stretch fabric?
No. Tricot can be made with or without spandex. Stretch depends on yarn, construction and finishing.
Is interlock fabric thicker than tricot fabric?
Often yes, but not always. GSM, yarn count and knitting structure decide the final weight and handfeel.
Which fabric is better for swimwear?
Tricot is commonly used for swimwear, especially when a smooth surface and stable stretch are required. The final choice still depends on opacity, recovery and chlorine or UV requirements.
Which fabric is better for sportswear?
Both can work. Tricot can suit smoother or lighter panels, while interlock can suit stable tops and structured sportswear.
