Our Seamless Series is the hottest trend of 2026! With irritation-free, seamless construction, enjoy all-day smooth comfort. Breathable, moisture-wicking fabric keeps you cool and confident anywhere.What Is Mercerized Cotton and Its Silk-Touch Finish?
Mercerized cotton is cotton treated with sodium hydroxide under tension, creating a silky luster, increased tensile strength by 20-30%, and smoother hand-feel ideal for luxury undershirts. The chemical process uses caustic soda to swell cellulose fibers, followed by rinsing and neutralization to lock in luster while preserving breathability. Sino Finetex leverages vertical integration from yarn development for precise mercerization in underwear basics like men’s briefs and boxer briefs using combed cotton and organic cotton.
How Does the Mercerization Chemical Process Work Step-by-Step?
The mercerization process immerses yarn or fabric in 20-30% sodium hydroxide at 15-20°C for 1-5 minutes to swell fibers and enhance luster. Tension is applied during rinsing to elongate fibers and prevent shrinkage, followed by neutralization with dilute acid. Sino Finetex’s in-house facilities ensure OEKO-TEX compliant, eco-friendly processes scaled for OEM luxury undershirts in materials like Pima cotton and combed cotton.
Why Choose Mercerized Cotton for Luxury Undershirts?
Mercerized cotton offers silk-like softness that reduces irritation for all-day wear, superior dye retention for vibrant colors, and durability with less pilling and shrinkage in performance basics. It suits premium undershirts, seamless tees, and sportswear bases needing moisture-wicking luxury feel. Sino Finetex, with 20+ years partnering global brands, uses 18 utility model patents for fitted mercerized designs in men’s tank tops and activewear.
