Principles of antibacterial technology and their application in terry cloth TPU film fabric
The core of antibacterial technology lies in inhibiting the growth and reproduction of microorganisms through physical or chemical means, thereby achieving the long-term antibacterial properties of the material. In terry cloth TPU film fabrics, contact-type antibacterial technology is mainly used. This type of technology destroys its cellular structure or metabolic process by making bacteria come into direct contact with antibacterial agents. Common antibacterial agents include metal ions (such as silver, zinc), organic compounds (such as quaternary ammonium salts), and natural extracts (such as tea polyphenols). Among them, silver ions are widely used for their broad-spectrum antibacterial properties and high efficiency.
Silver Ion Antibacterial Technology
Silver ion antibacterial technology is to immobilize silver ions on the surface of TPU membrane or fibers. When bacteria come into contact with these silver ions, silver ions will penetrate the bacteria’s cell wall and interfere with their DNA replication, ultimately leading to bacterial death. The advantage of this method is its efficient antibacterial ability and relatively low toxicity, and is suitable for a variety of textiles. According to literature reports, the antibacterial rate of silver ion-treated textiles to Staphylococcus aureus and E. coli can reach more than 99%.
Zinc antibacterial agent
Zinc antibacterial agents inhibit bacteria by releasing zinc ionsThe activity of the enzyme prevents bacteria from growing. Compared with silver ions, zinc ions are cheaper and have better biocompatibility, so they are more suitable in textiles for sensitive skin. Studies have shown that zinc-based antibacterial agents have particularly significant inhibitory effects on fungi and are suitable for textiles in humid and hot environments.
Organic Antibacterials
Organic antibacterial agents such as quaternary ammonium salt compounds exert antibacterial effects by changing the permeability of bacterial cell membranes. This type of antibacterial agent usually has good washing resistance and can maintain a high antibacterial effect even after multiple washes. However, some organic antibacterial agents may cause irritation to the human skin, so special attention should be paid to concentration control when used.
Natural Antibacterials
Natural antibacterial agents such as tea polyphenols and chitosan have attracted attention for their environmental protection and safety characteristics. These substances destroy proteins and nucleic acids in bacterial cells through redox reactions, thereby achieving antibacterial purpose. Although the stability of natural antibacterial agents is poor, their non-toxic and harmless properties make them potentially useful in the fields of infant products and food packaging.
To sum up, different antibacterial technologies have their own advantages and disadvantages. Choosing a suitable antibacterial agent requires comprehensive consideration of factors such as antibacterial efficiency, cost, safety and target application. For terry cloth TPU film fabrics, combining multiple antibacterial technologies can often achieve better results, and can also meet the needs of different user groups.
Process flow: Production steps of towel cloth TPU film fabric
The production of terry cloth TPU film fabric involves multiple precise process steps to ensure that the final product has excellent physical properties and can achieve efficient antibacterial functions. The following is the detailed production process:
Raw Material Preparation
- Fiber Selection: High-quality polyester or nylon fibers are used as the base material. These fibers are widely used for their high strength and wear resistance.
- TPU film preparation: Use thermoplastic polyurethane (TPU) raw materials to make a thin film after heating and melting through an extruder. The TPU membrane has good elasticity and waterproof and breathable properties, which is a key component of composite fabrics.
Composite Processing
- Odder coating: Evenly apply a layer of hot melt adhesive or other type of adhesive on one side of the fiber fabric. This step is important to ensure that the TPU film is firmly bonded to the fabric. important.
- Laminated composite: Place the TPU film on a fabric coated with adhesive and perform composite treatment through a high-temperature and high-pressure lamination device. The temperature is usually controlled between 180°C and 220°C, with a pressure range of 2 to 5 bar, depending on the material characteristics.
Anti-bacterial treatment
- Introduction of antibacterial agents: The antibacterial agent is evenly applied to the surface of the composite fabric by immersion or spraying. Commonly used antibacterial agents include silver ion solutions, zinc compounds and organic antibacterial agents.
- Currect and drying: After completing the antibacterial treatment, the fabric needs to undergo a drying process to remove excess moisture and fix the antibacterial agent. The drying temperature is generally set at around 120°C, and the duration is about 3 minutes.
After organizing
- Quality Test: Conduct a comprehensive quality inspection of the finished product, including indicators such as size, thickness uniformity, tensile strength and antibacterial efficacy.
- Cut Packaging: Cut qualified fabrics into specified sizes according to customer needs and properly packaged for transportation and storage.
| Process Steps | Main Operations | Key Parameters |
|---|---|---|
| Fiber Selection | Select the right type of fiber | Strength, wear resistance |
| TPU film preparation | Extrusion Mechanism Membrane | Temperature, speed |
| Odulant Coating | Evenerately coat hot melt adhesive | Coverage, Thickness |
| Laminated Composite | High temperature and high pressure composite | Temperature (180-220°C), Pressure (2-5 bar) |
| Introduction of antibacterial agents | Impregnate or spray antibacterial agent | Concentration, Coverage |
| Currect and dry | Dry and remove moisture | Temperature (120°C), time (3 minutes) |
| Quality Test | Comprehensive inspection of all indicators | Size, thickness, strength, antibacterial efficacy |
| Crop Packaging | Crop packaging on demand | Packaging method, logo |
Through the above strictly controlled process flow, the terry cloth TPU film fabric produced not only has excellent physical properties, but also has long-lasting antibacterial effects, meeting the needs of modern consumers for health and comfort.
Detailed explanation of product parameters: Physical properties and antibacterial properties of towel cloth TPU film fabric
Towel cloth TPU film fabric has excellent physical properties and antibacterial properties due to its unique composite structure. The following lists the main parameters and their specific values of the fabric in detail to better understand its characteristics and advantages.
Physical Performance Parameters
| parameter name | Unit | Value Range | Description |
|---|---|---|---|
| Thickness | mm | 0.2 – 0.5 | Affects softness and durability |
