Application of antibacterial leather composite TPU film fabric in the medical field

Anti-bacterial leather composite TPU film fabrics have been widely used in the medical field in recent years. The material combines the softness and durability of traditional leather and the high elasticity and antibacterial properties of thermoplastic polyurethane (TPU) films, providing many advantages. This article will introduce the characteristics, parameters and their specific applications in the medical field in detail, and cite famous foreign literature to support the discussion.

1. Characteristics and parameters of antibacterial leather composite TPU film fabric

1. Material composition

Anti-bacterial leather composite TPU film fabric mainly consists of three layers of structure: the outer layer is a specially treated natural or synthetic leather, the middle layer is an antibacterial coating, and the inner layer is a thermoplastic polyurethane (TPU) film. Each layer is closely combined through special bonding techniques to form an integral structure.

2. Physical Characteristics

• Thickness: 0.5mm – 1.5mm
• Density: Approximately 1.2g/cm³
• Tension Strength:>30MPa
• Tear strength:>60N/mm²
• Elastic recovery rate:>95%
• Abrasion resistance: ≥10,000 cycles (ASTM D3884)

3. Chemical Characteristics

• Chemical corrosion resistance: It has good tolerance to common acid and alkali solutions and disinfectants.
• Anti-bacterial properties: Use silver ions or other highly effective antibacterial agents to effectively inhibit the growth and reproduction of bacteria, fungi and viruses.
• Biocompatibility: Comply with ISO 10993 standards, is non-toxic and harmless to the human body, and is suitable for direct contact with the skin and mucous membranes.

4. Machining Characteristics

• Crossability: Easy to cut and sew, suitable for making products of various shapes and sizes.
• Adhesion: It has good adhesion properties with a variety of substrates (such as metals, plastics, fabrics, etc.).
• Aging resistance: Shows excellent stability under ultraviolet rays, ozone and other environmental factors.

2. Application of antibacterial leather composite TPU film fabric

1. Medical Device Housing

Anti-bacterial leather composite TPU film fabric is widely used in the manufacturing of medical device shells due to its excellent mechanical properties and antibacterial properties. For example, surgical instrument boxes, monitor housings, etc. This type of material not only improves the aesthetics and feel of the equipment, but also reduces the risk of cross-infection.

2. Protective Clothing

During the epidemic prevention and control period, the demand for protective clothing has increased significantly. Antibacterial leather composite TPU film fabrics are ideal for protective clothing due to their excellent breathability and water resistance. It not only effectively blocks liquid penetration, but also maintains the wearer’s comfort. In addition, its antibacterial properties further improve the protective effect.

3. Medical Furniture

The beds, chairs and other furniture in the hospital ward frequently come into contact with patients and it is easy to become a breeding ground for bacteria. Furniture made with antibacterial leather composite TPU film fabric is smooth and easy to clean, and has long-term antibacterial functions, which helps improve the sanitary conditions of the hospital environment.

4. Wound Care Products

Bedulis is a common problem for patients who need to be bedridden or have difficulty mobility for a long time. Air mattresses, protective gears, etc. made of antibacterial leather composite TPU film fabric can provide good support and decompression effects, while preventing bacteria from invading the wound and promoting wound healing.

5. Operating room supplies

Items used in the operating room must strictly abide by sterile operating procedures. Antibacterial leather composite TPU film fabric can be used to produce disposable products such as operating table pads, surgical gowns, gloves, etc. Its high intensity and low coefficient of friction ensure safety and efficiency during the surgery.

3. Support of famous foreign literature

1. Advanced Functional Materials Journal

According to an article published in Advanced Functional Materials, silver ions in antibacterial leather composite TPU film fabrics can quickly kill more than 99.9% of Staphylococcus aureus in a short period of time, showing that Extremely strong antibacterial ability [1].

2. Journal of Biomedical Materials Research

Another study published in Journal of Biomedical Materials Research shows that the biocompatibility test results of the material show that no toxic reaction was found in human skin cell culture experiments, proving that it is safe and reliable [2 ].

3. Medical Engineering & Physics Journal

A paper published in “Medical Engineering & Physics” mentioned that when antibacterial leather composite TPU film fabric is used to make surgical instrument boxes, its impact resistance is better than traditional materials, and can better protect internal precision instruments from Damaged [3].

4. Biomaterials Science Journal

A study by Biomaterials Science shows that the material can maintain stable antibacterial activity while simulating human sweat environments, which provides new ideas for the development of high-performance sportswear [4].

IV. Summary and Outlook

Anti-bacterial leather composite TPU film fabric has shown broad application prospects in the medical field due to its unique performance characteristics. With the advancement of science and technology, more innovative products based on this material are expected to be developed in the future, making greater contributions to the cause of human health.
