Is the antibacterial function of PE/PP bio-component Yarn achieved by adding specific antibacterial agents or by utilizing the inherent properties of the material?

The antibacterial function of PE/PP bio-component Yarn is mainly achieved by adding specific antibacterial agents during the yarn production process. These antibacterial agents are carefully selected and designed to effectively inhibit or kill bacteria that come into contact with the yarn, thereby protecting textiles made with this yarn from bacteria.
There are many types of antibacterial agents, including silver ions, copper ions, quaternary ammonium salts, organic acids, etc. In the production of PE/PP bio-component Yarn, the commonly used antibacterial agent is mainly silver ions, because silver ions have broad-spectrum antibacterial properties, high efficiency and durability. Silver ions can destroy the cell walls and cell membranes of bacteria, making the bacteria lose their ability to survive, thereby achieving an antibacterial effect.
There are two main ways to add antimicrobial agents to PE/PP bio-component Yarns: one is the spinning-level antimicrobial technology, that is, adding the antimicrobial agent directly to the spinning solution, and evenly distributing the antimicrobial agent inside the fiber through the spinning process; the other is the post-treatment antimicrobial technology, that is, after the yarn production is completed, the antimicrobial agent is applied to the yarn surface by dipping, coating or spraying.
The antimicrobial mechanism of antimicrobial agents in PE/PP bio-component Yarns mainly includes destroying bacterial cell walls and cell membranes, inhibiting bacterial metabolism and interfering with bacterial signal transduction. These mechanisms work together to enable PE/PP bio-component Yarns to effectively inhibit or kill bacteria in contact with them, thereby protecting textiles from bacterial invasion.
In practical applications, the antimicrobial effect of PE/PP bio-component Yarns depends on factors such as the type, amount, and method of adding antimicrobial agents and the production process of the yarns. Generally, PE/PP bio-component Yarns that have been optimized in design and production can exhibit good antimicrobial properties and effectively inhibit the growth and reproduction of bacteria.
When using PE/PP bio-component Yarn, although the antimicrobial agent generally has good wash resistance, overwashing may still lead to a reduction in the antimicrobial effect. Therefore, overwashing should be avoided as much as possible during use. The storage conditions of the antimicrobial yarn may also affect its antimicrobial properties. It is recommended to store it in a cool and dry place, away from direct sunlight and high temperature environment. When the antimicrobial yarn is used in specific areas, a strict safety assessment is required to ensure that it meets the relevant standards and requirements. This includes the evaluation of the toxicity, allergy and environmental impact of the antimicrobial agent.
