Bacterial cellulose: a revolutionary solution for textile fabrics to antibacterial and odorproof

Bacterial Cellulose (BC) is a natural polymer material produced by specific bacteria (such as Bacillus acetate). Because of its excellent physical and chemical properties, especially in antibacterial and anti-odorant performance, it has become a modern textile. An innovative material that has attracted much attention in the industry. Bacterial cellulose has higher purity and structural uniformity than traditional natural fibers. Its natural antibacterial and anti-odor properties make it widely used in high-end functional textiles. This article will deeply explore the antibacterial and anti-odor principles of bacterial cellulose in textile fabrics, and combine experimental data to analyze its technological content and application prospects.

1. Antibacterial principles and effects of bacterial cellulose

The antibacterial properties of bacterial cellulose are derived from its highly ordered nanofiber structure and its surface chemical properties. Bacterial cellulose molecules are closely connected through β-1,4 glycosidic bonds to form a highly crystalline nanofiber network structure. This structure not only gives bacteria a higher specific surface area of ​​cellulose, but also enhances its hydrophilicity, allowing it to physically and chemically interact with the bacteria's cell membrane and inhibit bacterial growth.

1.1 Antibacterial mechanism

The antibacterial effect of bacterial cellulose is mainly achieved through the following aspects:

Physical barrier function: The nanostructure of bacterial cellulose can effectively prevent bacteria from adhesion and spreading.

Chemical interaction: The hydroxyl and carboxylic functional groups rich in the surface of bacterial cellulose can interact with the phospholipid components of the bacterial cell membrane, destroying the integrity of the cell membrane, thereby inhibiting bacterial reproduction.

1.2 Experimental data on antibacterial effects

Experimental studies have shown that bacterial cellulose has a significant inhibitory effect on common pathogenic bacteria. Table 1 shows the inhibitory effect of bacterial cellulose on different bacteria.

It can be seen from Table 1 that bacterial cellulose has a significant inhibitory effect on Staphylococcus aureus, E. coli and Salmonella, with an inhibition rate higher than that of the control group, indicating that bacterial cellulose has significant antibacterial effects.

2. The anti-odor principle and effect of bacterial cellulose

The anti-odor function of bacterial cellulose is mainly achieved through the combined effect of hygroscopicity, breathability and antibacteriality. The body odor of the human body is mainly caused by the volatile compounds produced by bacteria breaking down fatty acids and proteins in sweat. Bacterial cellulose effectively reduces odor production through the following mechanisms:

2.1 Hygroscopicity and odor resistance

Bacterial cellulose is extremely hydrophilic and hygroscopic, and can quickly absorb sweat and keep textiles dry. Its high breathability ensures that sweat can evaporate rapidly, avoids moisture retention and bacterial growth conditions, thereby reducing the formation of body odor.

2.2 Antibacterial and odorproof

The natural antibacterial properties of bacterial cellulose can effectively inhibit the growth of bacteria on the surface of textiles. Bacteria are one of the main sources of body odor. By reducing the number of bacteria, bacterial cellulose can reduce the production of odor from the source.

2.3 Experimental data on anti-odor effect

In order to verify the effect of bacterial cellulose in deodorization, sweat simulation experiments were conducted. Table 2 shows the comparison of bacterial cellulose and ordinary fibers in anti-odor effects.

It can be seen from Table 2 that bacterial cellulose fabrics have a higher score in anti-odor effect, which is significantly better than traditional cotton and polyester fabrics, indicating that bacterial cellulose has strong anti-odor properties.

3. Technology content of bacterial cellulose antibacterial and deodorant applications

The application of bacterial cellulose is not limited to its natural properties, but its improvement in its antibacterial and anti-odor effects is also supported by modern technology. At present, the functionalized treatment technology of bacterial cellulose mainly includes the following aspects:

3.1 Nanotechnology and silver ion doping

Incorporating silver ions into bacterial cellulose through nanotechnology can significantly enhance its antibacterial properties. Silver ions have broad-spectrum antibacterial properties, which can destroy the cell walls of bacteria and inhibit the reproduction of bacteria. Bacterial cellulose doped with silver ions is better in antibacterial and anti-odor properties.

3.2 Functional surface modification

By chemically modifying the surface of bacterial cellulose, such as introducing antibacterial active groups (such as amino groups, quaternary ammonium salts, etc.), its antibacterial effect can be further improved. These modifications can enhance the inhibitory ability of bacterial cellulose on various pathogenic bacteria and enhance their anti-odor function.

3.3 Biodegradability and environmental protection

As a natural polymer material, bacterial cellulose has excellent biodegradability and will not cause pollution to the environment during use. Its environmentally friendly properties make it an important part of current green textiles.

4. Future Outlook

With the advancement of bacterial cellulose production technology, its production costs have gradually decreased and its application areas are also expanding. In the future, bacterial cellulose will not only be used for antibacterial and anti-odor functional textiles, but can also be combined with intelligent textile technology to develop more innovative materials with composite functions such as antibacterial, anti-ultraviolet rays, moisture absorption and sweating. In addition, the bio-based and sustainable characteristics of bacterial cellulose also provide huge market potential for its application in environmentally friendly textiles.

Summarize

Bacterial cellulose has become an important innovative material in the textile industry with its natural antibacterial and anti-odor functions, excellent physical and chemical properties and low production costs. Through modern scientific and technological means, the antibacterial and anti-odor effect of bacterial cellulose has been further strengthened and has been widely used in sportswear, underwear, medical and health products and other fields. In the future, bacterial cellulose will show greater application potential in functional textiles, green textiles and other fields.
