A blank program built around your own knit fabric specs means a manufacturer knits fabric to your exact requirements (fiber, yarn, construction, weight, and finish) and produces garments from it, either in your own fits or on proven existing bodies. It's the step between buying stock blanks and full custom production. It requires a manufacturer with in-house knitting and a clear fabric spec from you.
Here's what goes into a knit fabric spec, and how the development process works.
Why Brands Build Around Their Own Fabric
- Differentiation: a hand and weight competitors can't buy off the shelf
- Consistency: the same spec every reorder
- Control: fiber content, origin, and sustainability claims you can stand behind
- Brand identity: fabric is often what customers remember most
What Goes Into a Knit Fabric Spec
| Spec | What it defines |
|---|---|
| Fiber content | Cotton, recycled cotton, blends, Supima, and so on |
| Fiber origin | Where the cotton is grown and the yarn spun |
| Yarn count | Thickness (for example, 18/1 vs. 30/1) |
| Spinning method | Ring-spun, combed, or open-end |
| Construction | Jersey, rib (baby, 2x1), thermal, waffle, fleece |
| Weight | oz/yd² or GSM |
| Finish | Brushed, compacted, washed, garment-dyed |
| Shrinkage tolerance | Acceptable percentage after washing |
| Hand | How it should feel, ideally with a physical reference |
| Color | Pantone or physical standard, approved by lab dip |
The more precise your spec, the fewer development rounds you'll need.
How Development Works
- Share your spec or reference fabric. A physical swatch you love is the best starting point.
- Fabric development. The mill knits trial fabric to your spec.
- Lab dips. Color is matched and approved.
- Sampling. Garments are made from the developed fabric, in your fits or the manufacturer's.
- Approval. Fabric and garments are signed off.
- Bulk production. Fabric is knit and garments produced.
Your Fabric, Your Fit, or Both?
- Your fabric on existing bodies: faster, and uses fits that are already proven
- Your fabric and your fit: fully custom, with pattern development included
What to Look For in a Manufacturer
- In-house knitting, since fabric development moves faster when the mill is part of the operation
- A range of constructions beyond basic jersey
- Clear development costs and timelines
- Transparency on fiber origin
- The ability to produce both fabric and garments
