The Two Most Popular Embroidery Thread Types
If you've been in the commercial embroidery business for any length of time, you've encountered the ongoing debate: polyester thread vs rayon thread. Both are popular for machine embroidery, both produce beautiful results — but they have meaningfully different characteristics that make each better suited to different applications.
SA Embroidery supplies both polyester and rayon embroidery threads in wholesale quantities from Pakistan, shipping to clients in UAE, UK, USA, Saudi Arabia, and beyond. Here's what you need to know to make the right choice for your business.
What Is Rayon Embroidery Thread?
Rayon is a semi-synthetic fiber made from cellulose (wood pulp). Rayon embroidery thread was the industry standard for decades and remains popular for decorative embroidery. Its key characteristics:
- Exceptional sheen: Rayon has a silky, lustrous finish that closely resembles silk. Colors appear rich and vibrant.
- Soft hand: Rayon thread is soft to the touch, making it ideal for clothing items worn next to skin.
- Wide color range: Rayon is available in over 400 standard colors with excellent dye absorption.
- Weakness: Rayon breaks down faster under UV exposure and repeated washing, especially in chlorinated water.
What Is Polyester Embroidery Thread?
Polyester embroidery thread is fully synthetic, made from petroleum-derived polymers. Over the past 20 years, polyester thread quality has improved dramatically and now rivals rayon in appearance while offering significant practical advantages:
- Superior durability: Polyester resists fading, bleaching, and abrasion far better than rayon.
- Wash-resistant: Withstands industrial washing, bleach, and high-temperature drying without color loss.
- UV stable: Does not break down or fade under prolonged sunlight exposure.
- Consistent quality: Polyester has less natural variation than rayon, resulting in more consistent stitch quality.
Head-to-Head Comparison
Sheen & Appearance
Rayon wins — but only slightly. Rayon has a deeper, more natural sheen. However, modern high-quality polyester thread (such as our premium 120/2 polyester) has a very similar appearance that most customers cannot distinguish from rayon once embroidered.
Durability & Washability
Polyester wins decisively. For workwear, sportswear, uniforms, or anything that will be washed frequently — always choose polyester. Rayon can degrade, shrink slightly, or lose color after repeated industrial washing cycles.
Color Vibrancy
Roughly equal. Both produce vivid colors. Rayon may look slightly more vibrant straight off the machine; polyester maintains its color longer over the garment's lifetime.
Thread Breakage Rate
Polyester wins — polyester has higher tensile strength and breaks less frequently on high-speed multi-head machines, especially on small lettering and tight curves.
Price
Polyester wins — polyester thread is generally 10–20% cheaper than equivalent quality rayon thread and is widely available in bulk from Pakistani manufacturers.
Best Applications
| Application | Recommended Thread |
|---|---|
| Corporate uniforms & workwear | Polyester |
| Sportswear & athletic gear | Polyester |
| Fashion embroidery & decorative items | Rayon |
| Caps & hats | Polyester |
| Towels & home textiles | Polyester or Cotton |
| Evening wear & couture | Rayon or Silk |
Thread Weight: 120/2 vs 150/2
Thread weight (also called denier or weight/2) affects coverage and stitch count. 120/2 thread is thicker and provides better coverage — ideal for fill stitches, satin columns, and bold lettering. 150/2 is finer and better suited to small lettering and detailed designs. SA Embroidery supplies both weights in polyester and rayon.

Frequently Asked Questions
Common questions about this topic
1Which thread is better for embroidery on uniforms?
Polyester thread is strongly recommended for uniforms. It withstands industrial washing, bleach, and daily wear far better than rayon. It also maintains color vibrancy longer, keeping your branding looking sharp.
2Can I mix polyester and rayon threads on the same machine?
Yes, but keep in mind they have slightly different tension requirements. Polyester generally needs slightly lower upper tension than rayon. If switching between the two, adjust tension settings for each thread type.
3What thread weight do you recommend for most commercial embroidery?
120/2 polyester thread is the most versatile for commercial embroidery. It works well for logos, lettering, fill stitches, and satin columns. Use 150/2 for designs with very small text (under 5mm height).
4Do you supply thread samples before bulk ordering?
Yes, we can provide a sample color card and thread samples. Contact us via WhatsApp and specify the colors or color range you're interested in.
