Polyester Viscose Yarn vs Pure Polyester Yarn

When a supplier quotes you yarn, the two most common options are 100% polyester and polyester-viscose blend (T/R). They look similar on paper — both synthetic-based, both economical — but the fabrics they produce are very different. This guide compares them honestly so you can match the yarn to the garment.

What each yarn is

Pure polyester yarn is spun 100% from polyester staple or filament. It is strong, cheap and easy-care, but the fabric can feel plastic-like and wear hot.

Polyester-viscose (T/R) yarn blends polyester with 20-35% viscose (rayon). The viscose adds softness, drape and absorbency — transforming the hand feel of the fabric at a small cost increase.

Head-to-head comparison

Feature	Pure Polyester Yarn	Polyester Viscose (T/R) Yarn
Hand feel	Smooth but can feel synthetic	Soft, comfortable, drapes well
Moisture absorbency	Very low — wears hot	Moderate (viscose absorbs)
Strength	Excellent	Good
Pilling	Can pill in knits	Lower pilling at proper construction
Dye uptake	Moderate (needs disperse dyes)	Excellent, vivid colours
Wrinkle resistance	Excellent	Excellent
Cost	Lowest	Slightly higher (viscose costs more)
Best for	Linings, technical wear, budget basics	Suiting, workwear, fashion knitwear

When pure polyester yarn makes sense

• Cost-critical programs where every cent matters
• Linings and technical garments where strength and quick-dry beat comfort
• Industrial textiles that don't touch the skin directly
• Filament applications like sewing threads and mesh

When T/R yarn is the better choice

• Garments worn against the skin — the viscose makes it breathe and feel comfortable
• Suiting and workwear — professional drape and soft handle at a competitive price
• Colour programs — richer, faster dyeing than 100% polyester
• Fashion knitwear — lower pilling and a nicer surface

The price question

Pure polyester is the cheapest yarn per kg. T/R 65/35 adds roughly 10-20% to the material cost, but the finished fabric commands a higher market price and is far more wearable. For apparel programs, the value per garment usually favours T/R.

Frequently asked questions

Is T/R yarn better than pure polyester?

For apparel, usually yes — better hand, drape, absorbency and colour, at a modest cost increase. Pure polyester wins only where price is the sole driver or the fabric won't touch skin.

Does T/R yarn pill less than polyester?

At correct construction, yes. The viscose component changes the surface character and reduces the hard pilling seen in some 100% polyester knits.

Can I dye T/R yarn in bright colours?

Yes — viscose takes dyes readily, giving deeper, more uniform shades than 100% polyester.

Which do you supply?

We specialise in T/R blended yarn (65/35, 80/20 and custom ratios) from Ne 10s to Ne 40s, raw white or package-dyed. Send your specification for a quotation.
