When sourcing yarn, one of the first decisions is fibre type. For many apparel programs the choice comes down to T/R yarn (polyester-viscose blend) versus cotton yarn. Both produce comfortable, wearable garments — but they suit very different price points and end uses. Here is an honest comparison to help you decide.
Composition: what you are actually buying
Cotton yarn is spun from 100% natural cotton fibre. T/R yarn is a blend of polyester and viscose, most commonly 65/35. Neither is inherently "better" — they are different tools for different jobs.
Head-to-head comparison
| Feature | T/R Yarn (Polyester-Viscose) | Cotton Yarn |
|---|---|---|
| Raw material | Synthetic + regenerated fibre | Natural cotton fibre |
| Hand feel | Smooth, soft, fluid drape | Natural, breathable, absorbent |
| Strength & durability | Excellent | Good |
| Moisture absorption | Moderate (viscose helps) | Very high |
| Shrinkage | Low (stable) | Higher without pre-treatment |
| Wrinkle resistance | Excellent | Poor — creases easily |
| Colour fastness | Excellent | Good, varies by dye |
| Relative cost | Lower, stable supply | Higher, price fluctuates with market |
| Care | Easy care, quick drying | More careful washing needed |
When cotton yarn is the right choice
- Premium natural positioning: brands selling the "100% natural" story
- Next-to-skin comfort: babywear, premium tees and underwear where breathability and absorbency matter most
- Higher price tolerance: programs where the buyer pays for natural fibre
When T/R yarn is the smarter choice
- Cost-sensitive programs: workwear, uniforms, casual wear where price per kg drives the decision
- Wrinkle-free requirements: suiting and trousers that must hold their line
- Colour programs: vivid, fast dyeing at lower cost than cotton
- Easy-care garments: quick drying, low shrinkage, minimal ironing
The middle path: blends with cotton
If you need natural comfort and controlled cost, a polyester-cotton (T/C) blend sits between the two — see our guide T/R fabric vs T/C fabric for the full comparison. Some programs also mix viscose into cotton for drape at lower cost.
What buyers in practice choose
In our experience, garment factories serving mid-market apparel consistently choose blended yarns for cost stability, while premium and babywear programs stick with cotton. Many buyers run both: cotton for the hero items, blends for the volume range.
Frequently asked questions
Does T/R yarn feel like cotton?
Not exactly — it is smoother and drapes more fluidly. The viscose component adds softness, but it lacks cotton's characteristic natural hand.
Is T/R yarn cheaper than cotton yarn?
Usually yes, significantly, and with more stable pricing since the blend is less exposed to cotton market swings.
Can I use T/R yarn for t-shirts?
Yes — in finer counts it knits into comfortable, easy-care t-shirts, especially where wrinkle resistance and colour fastness are priorities.
Do you supply both yarns?
