Slub Cotton Tee Manufacturer: Texture, Yarn and QC

What is slub yarn?

Slub yarn is spun with controlled variations in thickness. When it is knitted into jersey, the thicker sections show as small raised streaks across the fabric. This gives a vintage, lived-in look that pairs well with garment dye and enzyme wash. Working with a slub cotton tee manufacturer means agreeing on the texture before anything else.

How to specify slub texture

Words like "light slub" or "heavy slub" mean different things to different mills. Instead, approve a physical fabric standard and reference it in the tech pack. Useful fields include:

• Slub frequency: how often the thick sections appear.
• Slub length and thickness relative to the base yarn.
• Fabric GSM after finishing, for example 220–260 GSM for a slub tee.
• Whether the texture should be visible after garment dye.

Slub vs ring-spun smooth jersey

Choose slub when the fabric is the story. Choose smooth jersey when a detailed screen print or DTG graphic is the focus.

Designed irregularity or defect?

This is where most disputes start. Holes, oil stains, dropped stitches, and barre (horizontal bands from yarn lot changes) are still defects on slub fabric. The slubs themselves are not. Write this in the inspection standard so inspectors do not reject good fabric or accept bad fabric because "it is supposed to look uneven."

Buyer QA practice: keep a sealed slub fabric standard with the approved sample and compare bulk fabric rolls against it before cutting.

Dye and wash behavior

Slub sections can absorb dye differently from the thin sections, which can make garment-dyed slub tees look slightly mottled. Many brands like this effect; some do not. Review the result on a washed and dyed sample of the actual color, not a lab dip on smooth fabric.

Printing on slub

Fine lines can break up on a slub surface. Water-based and discharge prints often sit into the texture and look natural, while thick plastisol sits on top. Test the artwork on the actual slub body during sampling.

Step-by-step approval

1. Approve a slub fabric standard.
2. Approve the washed and dyed body color.
3. Approve print or embroidery on the slub body.
4. Approve fit and shrinkage after wash.
5. Confirm defect rules that exclude designed slubs.
