Functional fibers can be antibacterial, odor-eliminating, or UV-protective, but how are they created? This article will give you a comprehensive understanding of functional fiber production technology. To learn about common fiber types and current usage trends, you can refer to the overview article “What is functional fiber? Applications in modern textiles.“

1. Overview of Modern Functional Fiber Production Technology Trends

The development of technology and the increasing demand for health, aesthetics, and convenience have driven significant changes in the textile industry. In this evolution, functional fiber is a crucial step forward, as it is not just a simple textile material but also carries functional value for the user.

From fibers with antibacterial, deodorizing, anti-UV, flame-retardant, and quick-drying properties—many of which have been analyzed in the article “A Comparison of Antibacterial and Conventional Fiber – Superior Advantages in Modern Textiles.“

The core difference between conventional and functional fibers lies in the production method: integrating properties from within (intrinsic) or adding supplementary treatments from the outside (extrinsic).

2. Classifying Functional Fiber Production Technology

Currently, functional fiber production technology is divided into two main approaches:

2.1. Intrinsic Functional Integration (from the core)

This technology allows manufacturers to blend functional particles (such as nano-silver, ceramics, or bioactive compounds) directly into the polymer base before spinning the fiber. As a result, the antibacterial or deodorizing properties are “firmly attached” to the fiber and last longer.

2.2. Extrinsic Functional Treatment (surface treatment)

After spinning the fiber or weaving the fabric, manufacturers can add functional properties by coating, immersion, or using enzyme or plasma treatments. This method is flexible and applicable to various materials, but its durability is often lower.

Criteria	Intrinsic (from the core)	Extrinsic (surface treatment)
Functional Durability	High (50–100 washes)	Medium (20–40 washes)
Investment Cost	Higher	More flexible, lower cost
Integration Level	Good, uniform throughout the fiber	Surface-level, easily loses effectiveness over time

3. Intrinsic Functional Fiber Technology

One of the prominent trends is the use of compound nanomaterial technology, where functional materials are dispersed into a polymer base such as polyester, nylon, or polypropylene before spinning.

Examples:

• Nano-silver (Ag+): Provides lasting antibacterial properties for medical apparel, underwear, and sportswear.
• Nano-ceramic: Reflects UV rays and helps retain body heat in cold weather.
• PCM (Phase Change Materials): Helps the fiber self-regulate temperature according to the environment.

Pioneering companies:

• Toray (Japan): Developed the AQUAIR® fiber line with nano-integration.
• Invista (USA): Applied antibacterial Lycra® for activewear.
• Hyosung (South Korea): Developed Creora Fresh®, an anti-odor and anti-static fiber.

A key advantage of intrinsic fibers is their high functional durability, which does not diminish after washing and can maintain properties throughout the product’s life cycle.

4. Extrinsic Functional Fiber Technology

This method relies on creating a coating or chemically altering the surface properties of the fiber or fabric after spinning. Common techniques include:

4.1. Coating / Finishing:

Applying antibacterial, anti-UV, or water-resistant chemicals using industrial calendering or coating machines.

4.2. Plasma Treatment:

Creating an activated surface to enhance the bonding between the fiber and the functional chemicals.

4.3. Enzyme Treatment:

Using bio-enzymes to break down odor-causing molecules like fatty acids or ammonia. This mechanism is analyzed in more detail in the article “Odor-Eliminating Fiber Technology: How Does It Work and Is It Really Effective?”.

The advantages of this technology are its low cost and easy applicability to various fiber types, including cotton and viscose. However, the functional durability will decrease with the number of washes and frequency of use.

5. Commonly Used Functional Materials

In the production of functional fibers, the choice of integrated material plays a crucial role in determining its effectiveness. Each material offers distinct properties suitable for different applications in the modern textile industry.

5.1. Nano-silver (Ag+)

5.2. Bio-enzymes

An environmentally friendly solution often used in odor-eliminating fiber treatments. Enzymes help break down odor-causing molecules like fatty acids or ammonia, making them very suitable for sportswear, socks, and products worn for extended periods.

5.3. Nano-zinc (ZnO)

In addition to its antibacterial properties, nano-zinc also has strong antifungal characteristics. It is an ideal material for school uniforms, children’s fabrics, or any product that requires a high level of safety for sensitive skin.

5.4. Titanium dioxide

This material is notable for its UV-blocking ability. When integrated into the fiber, titanium dioxide helps protect the skin from the effects of sunlight—especially useful in outdoor jackets, mountaineering gear, and work uniforms.

5.5. Activated charcoal

Activated charcoal is commonly used for odor control due to its ability to absorb volatile compounds. It is a popular choice for pillows, blankets, and furniture in enclosed environments like cleanrooms or high-end hotels.

6. Technical Standards and Testing

Why are more and more brands switching to using antibacterial fiber? This is a crucial topic within the “Functional Fiber” category, a modern direction in the textile industry. This article will help you understand the clear differences between antibacterial fiber and conventional fiber—in terms of effectiveness, applications, and cost.

1. Definition and Nature of the Two Fiber Types

Conventional fiber is a widely used material in traditional textiles, primarily including cotton, polyester, viscose, and others. These fibers do not incorporate additional features but simply provide mechanical durability and a comfortable feel.

In contrast, antibacterial fiber is a type of fiber integrated with active agents such as nano-silver, zinc ions, or plant extracts, or it is surface-treated to inhibit or kill the growth of odor-causing and harmful bacteria and fungi.

By nature, antibacterial fiber is “functional,” often undergoing high-tech processes such as:

• Integrating nano-materials into the fiber’s core (intrinsic).
• Surface coating or finishing (extrinsic).

2. Feature Comparison – Usage Effectiveness

Evaluation Criteria	Conventional Fiber	Antibacterial Fiber
Bacteria Elimination	None	Kills 99% of bacteria (AATCC TM100 standard)
Sweat Odor Control	None	Yes (eliminates odor-causing bacteria)
Safety for Sensitive Skin	Can cause irritation if damp	Reduces dermatitis, provides better skin protection
Long-term Hygiene	Prone to dirt and mold accumulation	Stays clean longer, provides continuous bacterial protection

A study from the Korea Textile Institute showed that nano-silver fiber reduced E.Coli and S.Aureus bacteria by up to 99.3% after 24 hours, while conventional fiber showed no similar effect.

3. Wash Durability, Reusability, and Environmental Impact

3.1. Wash Durability between Conventional and Antibacterial Fiber

Conventional fiber has no active protection, so bacteria and odors accumulate with each use if not treated with chemicals.

Antibacterial fiber, especially the type integrated into the fiber core, can maintain its effectiveness for up to 50–100 washes, without being washed away over time like surface-treated finishes.

Externally-treated antibacterial fibers have a shorter lifespan, averaging 20–40 washes, yet they still outperform conventional fiber in short-term use environments like uniforms, student apparel, and event clothing.

3.2. Environmental Impact and the Sustainable Consumer Trend

Beyond performance, a criterion that is gaining increasing attention in the textile industry is the environmental impact of the materials used. Conventional fibers like cotton, while natural in origin, have a production process that consumes a lot of water and pesticides. Meanwhile, polyester—a common synthetic fiber—takes hundreds of years to fully decompose in the environment.

Modern antibacterial fiber, especially that developed with a bio-based and sustainable approach, can reduce the number of washes needed, which means saving water, reducing the use of detergents, and minimizing the amount of microfibers released into the oceans. A report from Textile Exchange states that products using antibacterial fabrics can help reduce water consumption by 30% throughout the product’s life cycle.

Additionally, because antibacterial fiber stays clean longer, products made from this type of fiber are less likely to stain or degrade prematurely, extending their average lifespan by 1.5–2 times compared to conventional fiber under the same usage conditions. This is a crucial factor for brands aiming for an ESG (Environmental, Social, and Governance) strategy in their supply chain.

4. Practical Applications

Conventional fiber is widely used in everyday fashion, but it is easily affected by bacteria, moisture, and odors—especially in a tropical climate like Vietnam.

Antibacterial fiber, however, demonstrates a clear advantage in these applications:

• Medical apparel: Protects the wearer from cross-contamination.
• School uniforms: Reduces the risk of skin diseases.
• Sportswear: Limits sweat odor, increasing comfort.
• Office wear: Stays clean and odor-free all day long.

In fact, brands like Uniqlo, Decathlon, and Columbia have already adopted antibacterial fiber for their health-focused and sportswear product lines.

5. Production Costs and Economic Efficiency

Reliable References:

• OEKO-TEX® Certification
• AATCC TM100 – Antibacterial Finishes
• Textile World – Functional Textiles Market Report

The production cost of antibacterial fiber is 10–25% higher than that of conventional fiber due to the use of specialized materials and technology. However, in the long term, antibacterial fiber helps save costs:

• Reduced laundry frequency.
• Increased product lifespan.
• Lower return rates due to odor or skin irritation.

A 2023 survey by Textile World showed that European retailers are willing to pay 15% more for textile products that incorporate user-protective features.

6. Antibacterial Fiber in Brand Strategy and Sustainable Production

6.1. The Advantage of Building a Brand Based on Health and Safety Values

If your goal is low cost, mass production, or short-term use, conventional fiber might be the right choice.

However, if you are aiming for sustainability, user health, reduced operational costs, and elevated product value, antibacterial fiber is a worthwhile investment.

Especially in the post-pandemic context, consumers are strongly shifting towards products that offer health protection, are environmentally friendly, and provide long-term safety.

6.2. The Role of Antibacterial Fiber in the Global Supply Chain

Beyond being a technical solution, antibacterial fiber is also a tool for creating a brand’s competitive advantage in the era of smart consumption. Today’s consumers don’t just buy a shirt—they buy protection, peace of mind, and the ethical values associated with that product.

In Europe, over 42% of consumers are willing to pay more for textile products that incorporate health-protective features (according to Nielsen, 2022). For Vietnamese textile brands that want to export to the US or EU, adopting antibacterial fiber and obtaining certifications like OEKO-TEX or Bluesign will be key to expanding their market.

From a production standpoint, antibacterial fiber helps factories optimize their washing, packaging, and finished product storage processes, reducing rework costs and increasing the ability to control output quality. This is a tremendous advantage when participating in the global supply chain.

Antibacterial fiber is not just a material; it is a foundation for brands to build a green, clean, and responsible image in the eyes of global consumers.

Functional fibers are modern textile fibers integrated with advanced technologies for antibacterial, UV-protective, and odor-neutralizing properties. So what are they, who should use them, and how are they applied in the textile industry? This article provides a comprehensive overview.

1. Introduction to the Smart Fiber Trend

In the era of high technology and sustainable consumption, the textile industry is undergoing a major revolution with the emergence and development of functional fibers. No longer just a material for making fabric, today’s fibers are integrated with superior properties: antibacterial, odor-neutralizing, UV-protective, anti-static, flame-retardant, quick-drying, and even self-cooling.

The rise of functional fibers not only meets the demands of modern consumers but also opens up a new direction for the future of the textile industry: safe, smart, and environmentally friendly.

2. What Are Functional Fibers? How Do They Differ from Traditional Fibers?

Functional fibers are specially treated or integrated with unique properties to enhance the performance of textile products. These properties can be created through:

• Fiber composition: Integrated directly during production (e.g., silver nanoparticles, zinc nanoparticles, ceramics, etc.).
• Surface treatment: Coating with antibacterial or UV-protective agents, or using mechanical and chemical treatments.

Compared to traditional fibers, functional fibers excel at serving specific needs such as:

• Maintaining hygiene and safety: Antibacterial, odor-neutralizing.
• Increasing product durability and lifespan: Anti-wrinkle, flame-retardant.
• Providing comfort and convenience: Breathable, quick-drying.

3. Common Types of Functional Fibers

Functional fibers are distinguished not only by their technical features but also by the evolution they represent in the modern textile industry. Here are some of the most notable types:

3.1. Antibacterial Fibers

This is the most common type of functional fiber, integrated with silver nanoparticles, zinc nanoparticles, or silver ions to eliminate bacteria on the fabric surface. Brands like Uniqlo and Gap have used these fibers for their health and sportswear lines.

3.2. Odor-Neutralizing Fibers

These fibers use odor-absorbing compounds or silver nanoparticles to neutralize body odor and sweat upon contact. Many premium underwear and activewear products now use this type of fiber.

3.3. UV-Protective Fibers

These fibers prevent direct contact between UV-A and UV-B rays and the skin. They are typically coated with a UV Shield layer or woven with a dense fiber structure. They are suitable for outdoor apparel and construction uniforms.

3.4. Flame-Retardant Fibers

3.7. Quick-Drying Fibers

Materials like Tencel, bamboo fiber, and enhanced microfiber polyester wick away moisture extremely quickly, providing a cool feeling all day long. Adidas and Nike have applied these fibers in many of their running and training apparel lines. The durability of these properties is lower than those integrated from the fiber’s core.

4. Functional Fiber Production Technology

The technology for creating functional fibers is currently divided into two main approaches: integration from the fiber’s core and post-spinning treatment. Each method has its own advantages and limitations, depending on the intended use and the manufacturer’s investment budget.

4.1. Intrinsic Functional Fiber

This is a modern technology in which functional materials such as silver nanoparticles, zinc ions, ceramics, or PCMs are blended directly into the polymer resin before spinning. For example, when silver nanoparticles are integrated into polyester, it creates a durably antibacterial fiber that maintains its effectiveness for up to 100 washes. Toray (Japan) and Invista (USA) are pioneers in this technology.

The advantage of this method is the very high durability of the properties, which do not wash away. However, production costs are also higher due to the strict control required for input materials and precise blending technology.

4.2. Extrinsic Functional Fiber

This method uses coating, finishing, or plasma treatment technologies to apply a functional layer to the surface of the fiber or finished fabric. This is a flexible approach that can be applied to many types of fibers like cotton, polyester, and viscose at a lower cost.

However, the durability of the properties of these treated fibers often only lasts for 20–40 washes. Therefore, this type of fiber is more suitable for short-term use products or those that do not require frequent washing, such as event uniforms or medical face masks.

Choosing the right technology should be based on practical needs: if high durability and repeated use are required, the intrinsic method is preferable; if cost and flexibility are the priorities, post-spinning treatment is the optimal choice.

Permanent antiviral fibers are revolutionizing the textile industry by offering long-lasting protection against viruses. This article explores what these fibers are, how they work, who uses them, and how to produce, test, and apply them effectively.

1. What Are Permanent Antiviral Fibers?

Permanent antiviral fibers are textiles integrated with functional additives that neutralize or deactivate viruses on contact.

Unlike topical antiviral coatings, these fibers maintain their virus-fighting properties through repeated washes and extended use.

They are typically made using nanotechnology or embedded with metal ions such as silver, copper, or zinc.

Some variants use plant-based antiviral agents such as quaternary ammonium salts or chitosan derivatives.

2. How Do Antiviral Fibers Work?

These fibers disrupt virus structures by breaking protein shells, binding to viral DNA/RNA, or oxidizing key molecules.

Mechanisms vary by active agent:

• Silver ions penetrate cell walls and destroy genetic material.
• Copper oxide releases reactive oxygen species that destabilize viruses.
• Zinc ions inhibit virus binding to host cells.
• Chitosan forms a physical barrier and binds to viral proteins.

For more on copper’s antiviral properties, see this research by the US National Institutes of Health.

3. Applications of Antiviral Fibers

Used in:

• Face masks
• Medical scrubs
• Hospital bedding
• Uniforms for schools or airlines
• Home textiles (pillowcases, curtains)
• Sportswear and yoga clothing
• Travel accessories (blankets, pillows)

Especially critical during pandemics and in high-risk environments where hygiene is vital.

4. Who Uses Antiviral Textiles?

Industries such as:

• Healthcare: for infection control
• Apparel: for antiviral fashion lines
• Transport: airline and train seats
• Hospitality: antiviral linens for hotels
• Education: uniforms for students and teachers

Governments also procure antiviral uniforms for frontline workers and military use.

5. Manufacturing Antiviral Fibers

Antiviral functionality is added through:

• Dope dyeing: embedding active agents during fiber extrusion
• Masterbatch blending: incorporating agents into polymers
• Surface grafting: chemically bonding antiviral molecules to fiber surface
• Plasma treatment: to activate fiber surface for antiviral adhesion

Polymers like PET, PA6, viscose, and even biodegradable PLA are commonly used.

6. Standards and Testing Methods

To claim antiviral performance, fibers must be tested under standards like:

• ISO 18184: determines antiviral activity in textiles
• AATCC TM100: assesses antimicrobial durability
• JIS L 1922: Japanese industrial standard for antiviral efficacy
• GB/T 20944.3 (China): antibacterial and antiviral fabric evaluation

See also the ISO 18184 guideline overview for international validation.

Results are reported in log reduction values—e.g., 99.9% = 3 log reduction.

7. Benefits of Permanent Antiviral Fibers

Advantages include:

• Durable and washable protection
• Safer for sensitive skin compared to chemical finishes
• Eco-friendly (fewer disinfectants required)
• Increased product value and user confidence
• No need for post-wash reapplication

Unlike sprayed coatings, intrinsic antiviral yarns resist fading, leaching, or degradation.

8. Limitations and Safety Considerations

• Potential regulatory restrictions (e.g., REACH, EPA)
• Costlier production than conventional fibers
• Effectiveness may depend on humidity and viral load
• Heavy metals (silver, copper) require waste treatment controls

For safety guidance, review OEKO-TEX® chemical safety guide.

Always validate claims with third-party testing and ensure compliance with health regulations.

9. The Future of Antiviral Textiles

Emerging trends include:

• Plant-based antiviral agents (e.g., chitosan, tannins)
• Smart antiviral fabrics that release actives upon contact
• Multi-functionality: combining antiviral, antibacterial, and moisture-wicking in one fiber
• Biodegradable antiviral textiles for sustainable fashion
• AI-powered production lines that optimize fiber performance in real time

Global demand is rising in sectors like aviation, eldercare, education, and outdoor sports.ion, and outdoor sports.
