The Necessity of Antibacterial and Mold-Proof Fabric.
There are many microorganisms on the surface of human skin, some of which are beneficial bacteria for the human body, while others are pathogenic bacteria.
These microorganisms obtain nutrients from human secretions, sweat, and shedding skin, and undergo metabolic processes of growth, reproduction, and death. At the same time, the fatty acids and lactic acid in sweat and secretions can kill a variety of microorganisms. The mutual killing and inactivation of microorganisms contribute to their balance and coordination in quantity, which generally does not harm the human body.
Once this balance is disrupted, leading to bacterial imbalance, a small number of pathogenic bacteria will multiply rapidly and pose a threat to human health through the skin, respiratory tract, digestive tract, and mucous membranes of the reproductive tract.
Bacteria, fungi, and dust mites can cause significant damage and lead to various health issues. They can produce odors in underwear and sportswear, breed extensively in medical environments, cause allergic reactions, and may cause stains on indoor furnishings and other household items.
Microbial growth can also erode outdoor textiles, such as awnings, tents, or lawn furniture, and cause discoloration and degradation.
Mold is a type of fungus that can be found in almost any environment, including the air.
There are many different types of mold, and "black mold" usually refers to a type called Stachybotrys chartarum. Other common types include Alternaria, Aureobasidium, and Chaetomium.
It is important to note that mold in its early stages produces a musty odor and can be easily removed from surfaces. However, mold growth indicates that the fungus has matured and become more difficult to remove.
Fungi reproduce through spores and can proliferate on surfaces that are moist and rich in fibers, such as fiberboard, wood, gypsum board, and plasterboard, as well as in areas with small amounts of seepage or water leaks.
Harmful Effects of Mold
When black Aspergillus grows on fabrics, its spore masses appear black, causing the fibers to turn black, while Penicillium is yellow, and green mold is green. The branching spore fungus is brown, and so forth.
During their metabolic processes, molds and bacteria produce ethylene glycol, citric acid, oxalic acid, lactic acid, acetic acid, and other compounds, leading to unpleasant or peculiar odors, elevated fabric temperature, reduced luster, the development of mold spots, and potential harm to human health through skin contact or the respiratory system.
Black mold can produce toxins. It releases so-called mycotoxins, which are highly harmful to building residents. Of course, some individuals are more sensitive to fungal spores than others and may develop respiratory syndrome after inhaling small amounts of spores.
However, a place with a significant amount of mold toxins can lead to fungal poisoning in healthy individuals, depending on the concentration of mycotoxins, the duration of exposure to the toxins, and other contributing factors.
Exposure to fungi is more harmful for infants and young children. Research suggests that children exposed to mold may be more susceptible to developing asthma. In 2009, the World Health Organization released the "WHO Guidelines for Indoor Air Quality: Dampness and Mold," which offered a thorough review of scientific research on health issues associated with buildings and biological agents linked to dampness. The report concludes that the most significant impact of mold is to increase the prevalence of respiratory syndrome, allergies, and asthma, as well as to interfere with the immune system.
Therefore, to prevent mold growth during the storage, transportation, and pre-sale storage of dyed fabrics, it is essential to add fungicides into the treatment process. Additionally, applying antibacterial and antifungal finishes is crucial to inhibit mold growth.
Antibacterial and Mouldproof Fabric: An Overview
Antibacterial fabric refers to any fabric that can prevent the growth of bacteria, fungi, mold, and other pathogenic microorganisms.
This is achieved by treating the fabric with antibacterial finishing agents, which can inhibit the growth of harmful microorganisms, thereby enhancing the defense layer and extending the service life of the fabric.
Antibacterial fabrics are designed to combat the growth of bacteria, fungi, mold, and other microorganisms.
These antimicrobial properties are derived from chemical treatment or antibacterial finishing, which are applied locally to the fabric during the finishing process to provide them with the ability to inhibit microbial growth.
Advantages of Antibacterial and Mold-Resistant Fabric.
• Physical antibacterial
• Security category A
• Persistent antibacterial activity
• Breathable, lightweight, and long-lasting UV protection
• Absorb sweat, dry quickly, breathe well, and eliminate odors in the long term.
• Maintain bodily health by suppressing the growth of bacteria
Production of Antibacterial and Mold-Proof Fabric
There are three ways to implement antibacterial and deodorizing functions in synthetic fiber fabrics:
• Develop fibers that have inherent antibacterial properties, such as chitosan or chitin fibers;
• Antibacterial fibers are manufactured by mixing antibacterial agents into the spinning mother granules. This process ensures that the fibers themselves contain antibacterial agents, providing antibacterial and deodorizing functions, resulting in functional textiles.
• Utilize hygiene finishing agents to apply antibacterial finishing on the fabric after weaving, thus adding antibacterial and deodorizing properties to the textile.
The durability of the antibacterial effect of fabrics made from antibacterial fibers is superior to that of fabrics treated after weaving, but the cost is relatively high.
To treat fabrics with hygiene finishing agents, certain conditions must be met.
1. The amount used must be minimal while still having an inhibitory effect on bacteria.
2. It must be non-toxic and non-allergenic to humans.
3. It must be colorless, odorless, and non-viscous.
4. It must not cause bacteria to develop resistance.
5. It must be compatible with other agents.
6. The application process should be simple and provide a certain degree of wash fastness.
7. It must not accelerate fiber photolysis or degradation, and it must not affect the mechanical properties of fibers and fabrics.
Methods for Antibacterial Finishing of Fabrics
Surface Coating Method
Add the antibacterial agent to the coating material and apply it to the fabric using traditional coating techniques to ensure the antibacterial agent adheres to the fabric's surface.This method is suitable for any fiber fabric and can be used with certain inorganic or non-water-soluble antibacterial agents.
Immersion
Prepare the antibacterial agent in a specific concentration of finishing solution, add any other necessary auxiliaries, and immerse the fabric in the finishing solution.After centrifugal dehydration to achieve a specific moisture content, dry the material, and then bake it as required. This method is mainly used for knitted fabrics and towel products.
Immersion Roller
This method involves applying the finishing solution to the fabric using an immersion roller. It is primarily suitable for the continuous processing of flat fabrics and is a commonly used finishing process for woven fabrics.
Classification of Antibacterial Finishing Agents
Common antibacterial finishing agents can be divided into three categories: inorganic, organic, and natural products. Each has its advantages and disadvantages. In terms of environmental protection and human health, inorganic antibacterial agents offer the advantages of being non-polluting and safe. They are primarily used in the production of antibacterial functional fibers. In recent years, there have been studies on applying them to fabric finishing. Organic and natural antibacterial agents can be used in the production of functional fibers and for fabric finishing.
Antibacterial Mechanism of Antibacterial Agents
Inorganic Antibacterial Agents
Inorganic antibacterial agents are broad-spectrum antibacterial agents and belong to the contact-type antibacterial agents of ion dissolution. Their antibacterial action is passive.
Organic Antibacterial Agents
Organic antibacterial agents gradually penetrate the microbial cell by binding with anions on the surface of the microbial cell membrane or reacting with functional groups on the cell surface. This disrupts the synthesis system of proteins and cell membranes, inhibiting the reproduction of microorganisms.
Factors to Consider When Choosing Antibacterial Agents
1. Persistence
The durability of antibacterial properties in antibacterial textiles is essential for their effectiveness. Whether used in clothing or decorative textiles, their antibacterial properties require good wash resistance.
2. Processing Adaptability
Generally, antibacterial agents need to be combined with materials to prepare corresponding products. Therefore, the chosen antibacterial agents should exhibit good compatibility with the respective substrates and be adaptable to the processing needs of the substrates.In addition, after the antibacterial agent is added to the fiber or finished onto the textile, it should not affect the mechanical properties of the fiber and fabric, including strength, elongation, elasticity, etc., and it should not alter the appearance, color, or hand feel of the fabric.
3. Climate Resistance
Antibacterial materials and products are commonly utilized in indoor, outdoor, or open-air settings and are significantly influenced by climate conditions.Therefore, antibacterial agents need to possess a certain degree of climate resistance, including resistance to UV light, visible light, heat, and air.
4. Safety
The safety of antibacterial agents encompasses two aspects: the safety of their use and the biological safety required based on the environment of use.The safety of the usage process necessitates that the antibacterial agent should be safe for humans and the environment during use.

Testing Methods and Standards for the Antibacterial Performance of Textiles
Testing the antibacterial performance of fabrics can be divided into quantitative and qualitative methods, with the former being the most crucial.
1.Quantitative Testing MethodsThe quantitative testing method involves disinfecting the fabric, inoculating test bacteria, culturing the bacteria, and counting the residual bacterial colonies. It is suitable for non-leaching antibacterial finishing fabrics, but not for leaching antibacterial finishing fabrics. The advantages of this method are its quantitative, accurate, and objective nature, but the disadvantages include long testing times and high costs.
2.Qualitative testing methods mainly include AATCC 90-2011 (agar diffusion method, also known as the Petri dish method), AATCC 147-2011 (parallel streak method), and JIS Z2911-2010 (mold resistance method), among others. The qualitative testing method involves inoculating test bacteria on the fabric and observing the growth of microorganisms on the fabric with the naked eye. It is based on the antibacterial activity of the antibacterial agent that migrates from the fiber into the culture dish. This method is generally suitable for leaching antibacterial finishing but not for wash-resistant antibacterial finishing. The advantage of this method is its low cost and fast testing speed, but the disadvantage is that it cannot quantitatively measure the antibacterial activity, and the results are not accurate.
