If you’ve ever shopped for luxury bedding, you’ve probably come across the term thread count—often used as a marker of quality. Many people assume that the higher the thread count, the softer and more luxurious the fabric. But when it comes to silk, the story is a little different.
Silk has an undeniable softness and smoothness that even the highest-thread-count cotton struggles to match. But why? Let’s unravel the truth about thread count and explore what really makes silk feel so much softer than cotton.
What is Thread Count, and Why Does it Matter?
Thread count refers to the number of threads woven into a square inch of fabric, including both vertical (warp) and horizontal (weft) threads. In general, higher thread counts in cotton can mean a denser, smoother fabric—but only to a point.
Many manufacturers market high thread count as a sign of superior quality, but the reality is that once you go beyond 400-600 TC in cotton, the differences become negligible. In fact, some brands artificially inflate thread count by twisting multiple threads together, which doesn’t necessarily result in a softer or better fabric.
Why Silk Feels Softer—Without Relying on Thread Count
Silk is measured differently from cotton. Instead of thread count, silk quality is typically determined by mommes (mm)—a unit of weight that reflects the density of the silk weave. A higher momme weight (such as 22mm or 25mm) means a richer, more durable silk fabric.
Here’s why silk naturally feels softer than even the highest-thread-count cotton:
1. Silk Fibers Are Incredibly Fine and Smooth
Silk fibers are significantly finer than cotton fibers, which means they create a much smoother surface. While cotton can have a slight texture due to the shortness of its fibers, silk’s long, continuous filaments create an ultra-smooth, frictionless feel.
2. Silk Naturally Regulates Temperature
Cotton, even in its softest form, absorbs moisture and can feel heavier on the skin. Silk, on the other hand, is naturally temperature-regulating—it keeps you cool in the summer and warm in the winter, adding to its luxurious sensation against your skin.
3. Silk Contains Sericin, a Natural Protein
Sericin is a protein found in silk that helps retain moisture and protect the skin. This is why silk is often recommended for people with sensitive skin or hair—it reduces friction, preventing sleep wrinkles and hair breakage. Cotton, by contrast, is more absorbent, which can draw moisture away from your skin and hair while you sleep.
So, Does Thread Count Matter for Silk?
Not really! Unlike cotton, silk isn’t judged by thread count because of its completely different fiber structure. Instead, the quality of silk is determined by its:
✔ Momme weight (higher momme means better durability and softness)
✔ Grade (Grade A being the finest quality)
✔ Purity (100% mulberry silk is the gold standard)
The Bottom Line
While high-thread-count cotton can feel luxurious, silk’s natural properties make it softer, smoother, and more indulgent—without needing an inflated thread count. When shopping for silk bedding, focus on momme weight and purity rather than thread count to ensure you’re getting the best quality.
