Cooling Yarn

Wei-Syun Technical Fabrics: Integrating Cooling and Conductive Yarns

Cooling Yarn and Conductive Yarn are two distinct functional technologies, each serving a separate, independent purpose.

• Cooling Yarn: Its core function is sensory cooling and comfort.

• Conductive Yarn: Its core function is delivering electrical properties (e.g., anti-static, signal transmission).

As a specialized manufacturer of custom knit fabrics, Wei-Syun (Wei-Syun Industrial Co., Ltd.) does more than just produce these two materials. Our top-tier R&D capabilities allow us to integrate these two seemingly contradictory functions—heat dissipation and electrical properties—into a single textile. This is achieved through sophisticated structural engineering to meet the needs of highly specific and demanding markets.

A Critical Clarification:

It is important to note that when we integrate "cooling" and "conductive" technologies, we typically do not utilize the electric heating function of conductive yarn, as this is antithetical to the goal of cooling.

Instead, our focus is on the passive electrical properties of conductive yarns, such as:

• Anti-static / ESD (Electrostatic Discharge) Control

• Signal Transmission (Sensing)

• EMI (Electromagnetic Interference) Shielding

1. Cooling Yarn: Standalone Functions & Applications

Cooling yarn is our core product for hot climates and high-intensity athletic markets.

What is a Cooling Knit Fabric?

It is a textile engineered with specific yarn structures or additives that rapidly draw heat away from the skin upon contact. It is also designed to quickly evaporate moisture, maintaining a dry and comfortable state.

Key Features:

• Instant Cool-to-Touch

  Feature: By infusing the yarn with mineral powders that have a high thermal conductivity (e.g., jade powder, mica), the fabric immediately pulls heat away from the skin, creating an instant cooling sensation. This is typically measured by its Q-max value.

• Moisture Wicking & Quick-Dry

  Feature: Many cooling yarns are engineered with profiled cross-sections (e.g., cross-shaped or Y-shaped). This structure uses capillary action to rapidly pull sweat from the skin to the fabric's outer surface. This increases the surface area for evaporation, allowing moisture to dissipate quickly and achieving "evaporative cooling."

Standalone Applications:

• Sports Equipment: Manufacturing high-performance athletic apparel, cycling jerseys, and yoga wear.

• Home Decoration: Used in Curtain Knitted Fabric to help block thermal energy, or in summer-weight cooling bed sheets and pillowcases.

• Shoe Material: Used as a lining in Shoes Knitted Fabric to keep the feet dry and cool.

2. Advanced Application: Integrating Cooling + Conductive Yarns

This integration is where Wei-Syun's customization expertise truly shines. We provide composite solutions for demanding environments that require both extreme comfort and electronic protection simultaneously.

Integrated Feature: ESD-Safe & Cooling Comfort

We utilize the cooling yarn as the base "chassis" of the fabric, providing superior thermo-moisture management. We then precisely knit the conductive yarns into this base in a grid or stripe pattern to provide stable, passive electrical functionality.

The Synergistic Advantage:

In traditional industrial protective (PPE) or smart apparel applications, wearers must often endure hot, stuffy, and non-breathable materials. This is a significant "pain point." Wei-Syun's integrated technology solves this problem, achieving a perfect balance between high-tech performance and ergonomic comfort.

Integrated Applications:

1. Industrial & Protective Fabric

• Application: High-End ESD Garments / Cleanroom Apparel

• Scenario: Semiconductor fabs or precision electronics cleanrooms. Personnel must wear full-body protection in environments that are often hot, humid, and extremely sensitive to static.

• Wei-Syun Solution: We engineer a fabric using a high Q-max cooling yarn as the primary component, while integrating carbon or metallic fibers to meet strict industrial ESD standards. The final product delivers both certified anti-static safety and breathable cooling comfort, dramatically improving personnel productivity and well-being.

2. Smart Textiles & Medical Fabric

• Application: Smart Sportswear / Medical Monitoring Wear

• Scenario: An athlete or patient wearing a garment with biometric sensors (e.g., for ECG) for extended periods. Perspiration during activity or recovery can lead to heat buildup and discomfort.

• Wei-Syun Solution: We use our Single Jersey or high-stretch Mono Mesh knit with cooling yarns to create a high-wicking base. Using Jacquard technology, we then precisely knit conductive yarns (like silver fiber) into the structure to act as sensor electrodes. The result is a garment that stably transmits biosignals while keeping the wearer cool and dry.

3. Specialty Electronic Accessories

• Application: E-Sports / VR Equipment Accessories

• Scenario: E-sports arm sleeves or VR headset liners. Prolonged use leads to significant heat and moisture buildup. These items may also require "touch" functionality.

• Wei-Syun Solution: We provide a cooling conductive fabric that both wicks moisture and dissipates heat, while also integrating conductive yarns into specific zones (like fingertips) to enable touchscreen compatibility.

Conclusion: Wei-Syun's Integration Expertise

Wei-Syun possesses leading-edge composite-knitting R&D capabilities.
