Antibacterial and Antimicrobial Nonwoven Fabric Products

1. Product Foundation: Diverse High-Quality Substrates, Suitable for Different Antibacterial Scenarios

The performance differences of antibacterial and antimicrobial nonwoven fabrics begin with the precise selection of spunlace substrate raw materials. Our company selects various high-quality fibers such as polyester, viscose, cotton, and bamboo fiber, and scientifically mixes them according to the usage requirements of different fields to create spunlace substrates with both basic performance and adaptability, providing an excellent carrier for subsequent antibacterial finishing processes:

Polyester Fiber: Gives the substrate excellent tensile strength and tear resistance, ensuring that the substrate does not deform or break during antibacterial processing and use, while having good chemical resistance and aging resistance, suitable for complex environments such as healthcare and outdoor, ensuring long-term stable antibacterial effects;

Viscose Fiber: Comes with excellent moisture absorption and breathability, making the substrate more skin-friendly when in contact with the human body, reducing discomfort， and its fiber structure is conducive to the uniform attachment of antibacterial agents， improving the stability of antibacterial functions， suitable for hygiene products， home fabrics， etc.；

Cotton Fiber： Natural， environmentally friendly， and soft and skin-friendly， with excellent biocompatibility， no irritation， no odor， and strong moisture absorption， which can quickly absorb moisture and remain dry when paired with antibacterial finishing， becoming the preferred substrate for high-end scenarios such as mother and baby and healthcare；

Bamboo Fiber： Comes with natural antibacterial factors (bamboo quinone)， and forms a "double antibacterial" effect with the subsequent antibacterial finishing process. It also has good breathability and environmental degradability， aligning with the current green and healthy consumption trend， suitable for high-end home， personal care， etc.

We adjust the raw material ratio flexibly according to customer needs - for example， in medical scenarios， the proportion of polyester can be increased to enhance durability， while in mother and baby scenarios， full cotton / bamboo fiber is selected as the main material. Each batch of substrates undergoes multi-dimensional testing such as weight (30-200g/㎡ adjustable)， thickness， strength， and breathability， with errors controlled within a very small range to ensure stable substrate performance， laying a solid foundation for the precise implementation of antibacterial finishing processes.

2. Core Process： "Spunlace Substrate + Antibacterial Finishing"， Achieving Long-Term Antibacterial

Our antibacterial and antimicrobial nonwoven fabric strictly follows the step-by-step process mode of "preparing spunlace substrates first， then doing antibacterial finishing"， customizing optimized finishing schemes for different substrate characteristics and antibacterial requirements. Through refined control， we achieve "stable substrate + uniform antibacterial + long-lasting effect" triple guarantees：

(1) Pre-treatment of spunlace substrates： Enhancing antibacterial agent adhesion

Before antibacterial finishing， targeted pre-treatment is carried out on spunlace substrates：

For viscose， cotton， and bamboo fiber substrates with high moisture absorption， low-temperature drying (temperature 60-70℃) is used to remove excess moisture on the surface to avoid affecting the uniformity of antibacterial agent penetration；

For synthetic fiber substrates such as polyester， plasma surface treatment technology is used to slightly activate the surface active groups of the fibers， enhancing the binding force of antibacterial agents with the fibers， reducing the loss of antibacterial agents at the source， and ensuring long-lasting antibacterial effects.

(2) Fine-tuned Antibacterial Finishing： Customized Long-Term Antibacterial Solutions Based on the customized antibacterial finishing production line, according to the customers' requirements for antibacterial rate, antibacterial duration, and usage scenarios, different types of environmentally friendly antibacterial agents (such as quaternary ammonium salts, silver ions, and natural plant extracts) are selected to implement differentiated processing techniques:

Antibacterial agent selection: Strictly select antibacterial agents that comply with national environmental protection standards (such as GB 15979-2002, GB/T 20944-2007) - for medical scenarios, choose broad-spectrum and long-lasting silver ion antibacterial agents; for mother and baby, home, and hygiene products scenarios, choose mild and non-irritating natural plant extract antibacterial agents; for hygiene products scenarios, choose water-resistant quaternary ammonium salt antibacterial agents to ensure the safety and compliance of antibacterial effects;

Antibacterial agent application process: Select the appropriate application method based on the characteristics of the substrate fibers - for moisture-absorbing substrates such as viscose, cotton, and bamboo fibers, use the "immersion - rolling dry" process to allow the antibacterial agent to fully penetrate the fibers and ensure uniform antibacterial; for substrates with poor moisture absorption such as polyester, use the "spraying - drying" process, control the spraying amount of the antibacterial agent (5-10g/㎡ adjustable) through a high-precision spray head to avoid local accumulation or missed spraying, and ultimately achieve uniform distribution of the antibacterial agent on the surface and inside the substrate;

Curing and shaping process: After the application of the antibacterial agent, use a precisely temperature-controlled drying and curing process - natural plant antibacterial agents use low-temperature drying (70-80℃), avoiding the destruction of active ingredients; silver ions, quaternary ammonium salt antibacterial agents use medium-temperature curing (100-120℃), enhancing the binding force between the antibacterial agent and the fibers, ensuring that the product can withstand multiple washes (some models can maintain an antibacterial rate of ≥90% after 20 washes) and friction, and the antibacterial effect does not diminish, achieving long-term antibacterial.

III. Product advantages: Multiple characteristics combined, safeguarding health and safety

With diverse high-quality substrates and refined antibacterial finishing techniques, our antibacterial and antibacterial spunlace non-woven fabric has multiple core advantages, which can flexibly adapt to the health needs of different fields:

Strong material adaptability: Covers various substrates such as polyester, viscose, cotton, and bamboo fibers, can select suitable materials according to different scene requirements - for skin contact needs, choose cotton / bamboo fibers; for durability needs, choose polyester; for moisture absorption needs, choose viscose; achieve "one scene one material, one product one solution";

Safe and non-irritating: The selected antibacterial agents and raw materials all comply with national environmental protection and safety standards, without harmful heavy metals or volatile organic compounds release, undergo skin irritation tests (no redness, itching reactions), and can be safely used in scenarios directly in contact with the human body such as mother and baby, medical;

Balancing basic performance: Beyond the antibacterial function, the basic performance of the substrate itself, such as breathability, skin contact comfort, and strength, is not affected - cotton, bamboo fiber substrates are soft and skin-friendly, viscose substrates are moisture-absorbing and breathable, polyester substrates are strong and durable, meeting the usage experience requirements of different scenarios.
