Water-Based Nano Zinc Oxide Antibacterial Agent | Long-Lasting Antibacterial Functional Additive For Masks & Protective Nonwovens

With the continuous upgrading of public protection standards, ordinary protective nonwovens and mask fabrics can only achieve physical filtration. They fail to kill bacteria, fungi and viruses attached to the surface, easily causing bacterial growth, secondary pollution, stuffy odors during wear and short protection duration. Water-based nano zinc oxide antibacterial agent is an environmentally friendly inorganic antibacterial functional additive tailor-made for mask and protective nonwoven substrates. Adopting a pure water-phase dispersion system with uniformly sized, non-agglomerated and highly permeable nano particles, it perfectly fits industrial production processes of nonwovens including padding, dipping, spraying and coating. It endows various protective nonwovens, medical masks and protective fabrics with core functions of broad-spectrum and long-lasting antibacterial performance, mite inhibition and deodorization, skin-friendliness and zero irritation, and uncompromised air permeability, making it a preferred raw material for upgrading protective consumables.

Tailored to the characteristics of various nonwoven substrates such as PP, PET, spunbond, melt-blown and spunlace, this water-based nano zinc oxide antibacterial agent overcomes the shortcomings of traditional organic antibacterial agents and solves multiple industry pain points, suitable for medical, civil and industrial protection scenarios:

Pure Water & Eco-Friendly System, Compliant and Risk-Free: Formulated with pure water, solvent-free, formaldehyde-free and free of heavy metal precipitation and irritating chemical ingredients. It is skin-friendly and non-allergenic, fully complying with safety standards for close-fitting protective consumables such as masks. It avoids the common drawbacks of organic antibacterial agents including residual substances, skin irritation and peculiar odors.

Uniform Nano Dispersion, No Pore Blockage & Unimpaired Air Permeability: Treated with exclusive surface modification technology, nano zinc oxide particles are stably dispersed in water with fine and uniform particle size and strong penetration and adhesion. They evenly attach to nonwoven fiber gaps without blocking fabric micropores, fully retaining the air and moisture permeability of masks and nonwovens. The finished products prevent stuffiness and sweat during wear, balancing excellent protection and wearing comfort.

Broad-Spectrum & High-Efficiency Antibacterial Performance, Secondary Pollution Prevention: Adopting a triple antibacterial mechanism of zinc ion slow release, reactive oxygen oxidation and physical puncture, it can rapidly kill common pathogenic bacteria such as Escherichia coli, Staphylococcus aureus and Candida albicans, and deliver excellent inhibitory effects on influenza viruses. The fabric antibacterial rate reaches up to 99.99%, effectively preventing bacterial accumulation and cross-infection on mask surfaces and solving the core defect of traditional protective materials that only filter but cannot sterilize.

Long-Lasting Water Wash Resistance & Stable Performance: It features strong bonding force with nonwoven fibers and forms stable and durable coatings that are not easy to fall off. The antibacterial performance remains stable after repeated washing and friction, without antibacterial failure, fabric yellowing or powder shedding, greatly extending the service life and protection stability of protective consumables.

Full Process Compatibility & Controllable Mass Production Cost: With good fluidity, no stratification and no precipitation, it can be directly diluted with water for use. It is perfectly compatible with automated nonwoven production processes such as bathing, padding, single-sided spraying and composite coating, requiring no equipment renovation and suitable for large-scale industrial mass production.

Weather Resistance & No Drug Resistance: As an inorganic antibacterial material with stable properties, it resists high temperature, oxidation and degradation. It causes no bacterial drug resistance during long-term use, different from organic antibacterial agents that are prone to failure and drug-resistant bacteria breeding, realizing long-term stable antibacterial protection.

This product is specially adapted to all types of protective-grade nonwoven substrates, widely used in medical protection, daily civil protection and industrial isolation protection to empower functional upgrading of protective products:

Suitable for functional antibacterial layer processing of outer and middle layers of medical surgical masks, medical protective masks, civil dust masks and children's protective masks. Through fabric pretreatment, the masks gain active sterilization, deodorization and mildew-proof capabilities, effectively eliminating stuffy odors and bacterial growth caused by long-time wear. It upgrades masks from passive physical filtration to active antibacterial protection and comprehensively improves the protection level.

Applicable to antibacterial finishing of medical protective clothing, isolation gowns, protective mask base fabrics, medical caps, medical shoe covers, disposable sterile bed sheets and other nonwoven consumables. In high-bacteria-density medical scenarios, nonwovens treated with this additive can long-term inhibit bacterial adhesion and reproduction, reducing cross-infection risks for medical staff and isolated personnel, meeting high-standard protection requirements of hospitals, CDC and nucleic acid testing sites.

Used for processing disposable sanitary wipes, facial cleansing towels, maternal and infant protective nonwovens, pet protective mats and household isolation protective fabrics. It develops safe antibacterial fabrics for maternal, infant and sensitive skin groups with mild and non-irritating properties, which can not only block external bacteria but also inhibit bacterial growth on the fabric itself, balancing safety and practicality.

Compatible with air filter nonwovens, fresh air filter base fabrics, industrial dust-proof protective fabrics and outdoor isolation nonwovens. While realizing physical filtration, it achieves antibacterial, algae-inhibiting and deodorizing effects, preventing moldy odors and bacterial accumulation on long-term used filters and protective fabrics and extending the replacement cycle of protective consumables.

This water-based nano zinc oxide antibacterial agent features strong adaptability, simple operation and low technical threshold, compatible with most nonwoven production processes:

Application Methods: Directly dilute with water, applicable for padding, dipping, spraying, surface coating and internal pulp addition
