Multi-Functional Cool Touch Antibacterial Fiber
Customized Fiber Solutions for Advanced Textiles
Combining cool-touch and antibacterial performance with customizable functional options, our composite polyester staple fiber supports moisture wicking, UV protection, far-infrared and anti-static applications. Built-in functionality and flexible configurations help meet diverse textile requirements.
Product Overview
The Cool Sensation Antibacterial Composite Functional Fiber is a multi-functional polyester staple fiber (PET) built on a "core function + optional functions" design: cool- touch and antibacterial are the standard configuration, while moisture wicking (quick- drying), UV protection, and deodorant functions can be selectively combined according to the end application, forming multiple functional combinations. Functionality is built in via the masterbatch route - cool-conducting mineral filler (e.g., jade or mica), antibacterial agents (zinc, silver or copper ions), and each optional functional additive are compounded into high-loading functional masterbatches, then injected into the PET melt at controlled dosing rates during melt spinning. The functional components disperse uniformly and stay embedded in the fiber body, so performance does not rely on post-finishing coating and durability is inherent to the fiber. The cross-section is round by default, with cruciform and trilobal profiles available on request for enhanced cool-touch, moisture transport, and hand feel; natural white is the stock color, with dope-dyed shades available. This polyester staple fiber runs on standard PET staple spinning lines without equipment conversion.
Technology Principle
This polyester staple fiber is produced by a compound melt-spinning route:
1. Compound spinning route – twin-screw compound melt spinning. Functional masterbatches are fed into the extruder together with PET chips at the set recipe ratios, melted and homogenized, then extruded through the spinneret into filaments.
2. Functional distribution – the cool-touch filler, antibacterial agents, and auxiliary masterbatches disperse evenly in the PET matrix, without interfering with one another or hurting the spinnability of this polyester staple fiber.
3. Cool-touch mechanism – the thermal conductivity of jade or mica powder (5–50 W/(m·K)) is far higher than that of PET (about 0.3 W/(m·K)). The moment skin touches the fiber, heat is conducted away along the powder, creating a cool feel.
4. Antibacterial mechanism – metal ions (Zn²⁺/Ag⁺/Cu²⁺) work by disrupting bacterial cell membranes, binding to DNA, and interfering with enzyme activity, giving broad-spectrum antibacterial performance. Single-ion or compound formulas can be selected to suit the end use and regulatory requirements.
5. Auxiliary functions
• UV protection: zinc oxide, titanium dioxide, or similar UV-shielding agents, UPF ≥ 50;
• moisture wicking: capillary channels formed by profiled cross-sections such as cruciform or hollow;
• far-infrared: IR-emitting ceramic powder that radiates far-infrared at body temperature;
• anti-static: carbon nanotubes or conductive metal oxides.
Core Advantages
Multi-function in one fiber
Cool-touch, antibacterial action, and the selected auxiliary function are built into the fiber itself - no coating stack needed.
Adjustable recipe
Auxiliary functions are chosen on demand - UV resistance, moisture wicking, far-infrared, or anti-static - with more than 30 specification combinations available.
Durable performance
All functions come from the fiber body rather than surface treatment, remaining effective after 50 wash cycles or more.

Applications
1) Functional sportswear. Running, yoga, fitness, and outdoor apparel where cool-touch, antibacterial action, and an auxiliary function (often UV) combine.
2) Skin-contact innerwear. Cool-touch antibacterial underwear, loungewear, and infant close-to-skin items.
3) Home-textile bedding. Antibacterial four-piece sets, fitted sheets, and pillow covers.
4) Hosiery. Performance sports socks, business socks, and infant socks.
