Mercerized Cotton
Cotton treated with sodium hydroxide under tension to improve luster, strength, and dye affinity. The process permanently alters the fiber structure for a silky sheen.

What this score doesn't measure
This is a material rating, not a verdict on any specific garment made from mercerized cotton. The axes above are research-backed averages for the fiber itself.
- ×Construction. Yarn staple length, weave / knit structure, stitch count, finishing. Identical fiber, very different garments.
- ×Fabric weight (GSM). A 140 GSM tee and a 220 GSM tee made of the same mercerized cotton feel and last very differently.
- ×Dye + finishing chemicals. Beyond the three we flag (PFAS, formaldehyde, antimony), dozens of textile finishes aren't modelled.
