Infrared Yarn

Wei-Syun Technical Fabrics: Integrating Infrared and Conductive Yarns

It is essential to first clarify that Infrared (IR) Yarn and Conductive Yarn are two distinct functional technologies, each with its own unique principles and applications.

• Infrared (IR) Yarn: Its core function is therapeutic warmth and wellness.

• Conductive Yarn: Its core function involves electrical properties (e.g., anti-static, signal transmission, and active electrical heating).

As a leader in customized knit fabrics, Wei-Syun (Wei-Syun Industrial Co., Ltd.) not only develops textiles for each of these functions independently; our true strength lies in our R&D capability to integrate them. This synergy creates high-value-added Smart Textiles that leverage the benefits of both.

We will focus on how these two yarns can be applied individually and, more importantly, synergistically.

1. Infrared (IR) Yarn: Standalone Functions & Applications

Infrared Yarn is one of our flagship functional materials, typically referring to Far-Infrared (FIR) Yarn.

What is an FIR Knit Fabric?

This is a functional textile created using yarns that have been melt-spun with nanoscale ceramic powders (such as zirconium oxide or titanium dioxide) permanently embedded within the fiber's core.

Key Features:

• Passive Thermal Regulation

  Feature: This yarn absorbs the body's natural heat (bio-energy) and converts it into Far-Infrared waves (typically 4-14 µm), which are then re-emitted back to the body. This energy gently raises the subcutaneous temperature (approximately 0.5°C to 1.5°C), generating exceptional thermal retention without causing stuffiness or overheating.

• Enhanced Microcirculation

  Feature: Often called the "light of life," these FIR wavelengths resonate with water molecules in the body. This activation can help improve blood flow and velocity in the capillaries (microcirculation), which in turn aids metabolism and can help soothe muscle fatigue and minor soreness.

• Durable and Safe

  Feature: Because the ceramic particles are permanently embedded at the fiber level, the function will not wash out or degrade over time. The effect is triggered entirely by the body's own heat, requiring no external power, making it exceptionally safe.

Standalone Applications:

• Sports Equipment: Used in compression wear, athletic braces (knee, elbow), or socks. Its microcirculation-enhancing properties can aid in athlete warm-ups and accelerate post-workout recovery by helping to metabolize lactic acid.

• Medical & Rehabilitation (Medical Knitted Fabric): Ideal for rehabilitation braces, therapeutic supports, or diabetic socks, where improving peripheral circulation is key to health.

• Performance Apparel & Home Textiles (Home Decoration): Used to create high-quality thermal underwear, sleepwear, or premium blankets and bedding (Home Decoration) that provide a comfortable, restorative sleep temperature.

2. Advanced Application: Integrating IR + Conductive Yarns

This integration showcases Wei-Syun's most advanced customization capabilities. When a client requires more than just passive warmth and needs powerful, active thermal therapy, we engineer a composite fabric that integrates both yarns.

Integrated Feature: Dual-Action Thermal Therapy

We utilize Conductive Yarns as the active heating element (via resistive heating) and pair them with Infrared Yarns as the therapeutic wellness lining.

• Active Heating (Conductive Yarn): When connected to a power source (e.g., a USB power bank), it rapidly generates stable, controlled heat (e.g., 40°C - 55°C / 104°F - 131°F).

• Synergistic Effect (Infrared Yarn): This skin-facing layer absorbs the heat from both the active conductive element and the user's body, converting it all into therapeutic Far-Infrared waves that are directed back to the wearer.

The Synergistic Advantage:

This combination creates a powerful 1+1 > 2 effect. The result is not just "heat"; it is "heat therapy." The conductive yarn provides the primary, high-level warmth, while the IR yarn ensures this thermal energy is delivered more deeply and effectively into the subcutaneous tissue. This dramatically enhances the therapeutic efficiency and the circulatory benefits of the heat.

Integrated Applications:

• Smart Medical & Therapeutic Braces:

  We can use our Jacquard Sandwich Cloth (Spacer Fabric) structures to safely embed the conductive heating grid within the fabric's layers, while using the IR-infused yarn for the skin-contact layer. The result is a high-end "active therapeutic knee brace" or "heated back support" that provides deep, soothing relief.

• High-End Smart Apparel:

  Applied in heated vests, jackets, or gloves for extreme outdoor sports or polar work. The conductive yarn provides critical survival warmth, while the IR yarn ensures that heat is used efficiently and helps maintain healthy circulation in extreme conditions.

• Athletic Recovery Equipment:

  Used to create "active recovery blankets" or heated massage apparel for professional athletes. This combination of electrical heat and FIR technology works to rapidly relax and restore fatigued muscles.

Conclusion: Wei-Syun's Integration Expertise

Wei-Syun Industrial possesses top-tier R&D capabilities for developing composite knit fabrics that integrate multiple functional yarns.

While standalone Infrared Yarn is our premier solution for advanced wellness and thermal regulation, the integration of IR and Conductive Yarns is our unique, customized service for clients seeking to build high-performance "smart thermal therapy" textiles. This perfectly embodies our corporate philosophy: to "master new technologies and create new trends."
