As a natural fiber product, jute filling rope is susceptible to microbial erosion and moth infestation in a humid environment, which affects its service life and safety. Although traditional chemical antibacterial and moth-proofing agents have significant effects, they have problems such as chemical residues and environmental pollution. Therefore, the development of green and environmentally friendly treatment technologies can not only effectively protect jute filling ropes, but also conform to the concept of sustainable development, and has become the focus of industry attention.
Many natural plants contain active ingredients with antibacterial and moth-proofing properties, which can be used to treat jute filling ropes. For example, essential oils extracted from plants such as cinnamon and cloves are rich in cinnamaldehyde, eugenol and other ingredients, which can effectively inhibit the growth of common microorganisms such as Escherichia coli and Staphylococcus aureus, and have a repellent effect on moths. These plant essential oils are mixed with degradable and environmentally friendly adhesives, and attached to the surface of jute filling ropes by dipping, spraying, etc., to form a natural antibacterial and moth-proofing protective film. This method is not only safe and non-toxic, but also these plant ingredients can be naturally degraded over time without polluting the environment.
Using biological agents for treatment is an effective way to be green and environmentally friendly. Antimicrobial peptides produced by probiotic fermentation, such as nisin, have a strong inhibitory effect on common molds and moths. The fermentation liquid containing antimicrobial peptides is evenly applied on the jute filling rope. The antimicrobial peptides can penetrate the cell membrane of microorganisms, destroy their cell structure, and achieve antibacterial effects; at the same time, their special smell can keep moths away. In addition, the mycelium produced by certain fungi is used to wrap jute fibers, forming a physical barrier on the fiber surface to prevent the invasion of microorganisms and moths. This biological barrier also has the characteristics of natural environmental protection.
Physical treatment technology does not introduce chemical substances, and achieves antibacterial and moth-proofing by changing the structure of jute fibers. Low-temperature plasma treatment is used. In a vacuum environment, high-energy particles in the plasma are used to bombard the surface of jute fibers, changing their surface structure, producing tiny bumps and holes, increasing the specific surface area of the fibers, and activating chemical groups on the fiber surface. These changes help to improve the fiber's adsorption capacity for natural antimicrobial substances, allowing them to better adhere to the fiber surface and enhance the antibacterial and moth-proofing effects. In addition, ultraviolet irradiation treatment can destroy the DNA structure of microorganisms and moths, making them inactive, achieving the purpose of protection, and no harmful substances will remain.
Due to its unique properties, nanomaterials have shown great potential in the antibacterial and anti-moth treatment of jute filling rope. Antibacterial nanomaterials such as nano titanium dioxide and nano zinc oxide are evenly dispersed in environmentally friendly water-based resins to make nano composite coatings. The coating is attached to the surface of the jute filling rope by dipping or spraying, and a dense nano-level protective film is formed after drying. Nanomaterials are highly active and strongly oxidizing, and can continuously release antibacterial ions, destroy the cell structure of microorganisms, and inhibit their growth and reproduction; at the same time, the protective film can also block the gnawing of moths, and the nanomaterials themselves are non-toxic and harmless, meeting the requirements of green environmental protection.
Single treatment technology often has certain limitations, and the use of composite treatment technology can give play to the synergistic effect of multiple methods. For example, the jute filling rope is first treated with natural plant extracts to give it basic antibacterial and moth-proofing properties; then combined with nanomaterial modification, a solid protective layer is formed on the surface; finally, physical treatment technology is used to further optimize the fiber structure and improve the durability of the treatment effect. This composite treatment method can not only give full play to the advantages of various technologies, but also reduce the shortcomings that may be caused by a single technology, achieve more efficient and lasting antibacterial and moth-proofing effects, while maintaining green and environmentally friendly characteristics.
There are many green and environmentally friendly solutions for the antibacterial and moth-proofing treatment of jute filling rope, including natural plant extract treatment, biological agent treatment, physical treatment technology, nanomaterial modification, and composite treatment technology. These methods start from different angles, using natural substances, physical means or environmentally friendly materials, while effectively protecting the jute filling rope, avoiding harm to the environment and human health. With the continuous development and innovation of technology, more efficient and environmentally friendly antibacterial and moth-proofing treatment technologies will be applied to the field of jute filling rope in the future to promote the sustainable development of the industry.
