Cool Touch & Antibacterial Polyester Fiber
Dual-Function Fiber for Lasting Freshness and Comfort
Combining cool-touch minerals with built-in antibacterial technology, our functional polyester staple fiber delivers a refreshing feel and durable antibacterial performance for innovative textile applications.
Product Overview
This is one of the functional polyester fibers that brings cool-touch and antibacterial action together in a single filament. The masterbatch route is how we do it: the mineral filler and the antibacterial agent are each compounded into high-loading concentrates first, then metered into the PET melt at controlled rates while spinning. Typical loadings are 2%–8% for the mineral filler and 0.5%–2.0% for the antibacterial package.
Because the functional particles stay embedded in the fiber, the wash durability is built in - no finishing bath, no coating that rubs off over time. The default cross-section is round. If hand feel or cool intensity needs to go further, we can spin cruciform or trilobal profiles to order. Stock color is natural white; dope-dyed shades are available.
On fabric, Q-max lands at ≥ 0.30 W/cm², comfortably above the 0.15 national threshold. Antibacterial performance reaches AAA grade under FZ/T 73023-2006 - after 50 standard washes, reduction stays at ≥ 80% for S. aureus, ≥ 70% for E. coli, and ≥ 60% for C. albicans. The product line covers three families (basic, cool-touch enhanced, antibacterial enhanced), and you can pick zinc, silver, or copper singly or as a compound formula
Technology Principle
The functional polyester fibers on this platform work through two built-in mechanisms:
1. Cool-touch mechanism – the thermal conductivity of the mineral filler (5–50 W/(m·K)) is far higher than that of PET (about 0.3 W/(m·K)). On contact with skin, heat moves quickly along the filler–matrix interface, creating a cool sensation.
2. Antibacterial mechanism –
- Zinc (ZnO/Zn²⁺): disrupts bacterial cell membranes and interferes with enzyme activity; safe for skin contact and commonly used in next-to-skin wear.
- Silver (Ag⁺): binds to bacterial DNA and proteins; broad spectrum with high efficiency.
- Copper (Cu²⁺): inhibits bacteria while also providing antifungal performance.
Customers can choose a single metal ion or a compound formula depending on the end use and regulatory requirements.
Core Advantages
Dual Function In One Fiber
Cool-touch and antibacterial action come from the fiber body itself, with no post-finishing coating required.
Durable Performance
Both survive 50 wash cycles or more.
Flexible Recipe
Zinc, silver, and copper can be combined in different ratios to match the regulatory framework and the price target.
Specification Flexibility
Fineness, cut length, color, crimp, and cross-section profile are all adjustable. The ice fiber base technology is shared with the cool-touch enhanced family, and the same platform can also produce thermal insulation fiber grades for winter use.
