Abstract
A color-change-resistant antibacterial nylon fiber is mainly prepared from nylon and antibacterial master batch according to the weight ratio of 100: 1-10; the antibacterial master batch comprises the following raw materials in percentage by weight: 70-95% of long carbon chain nylon, 5-30% of silver-loaded ion antibacterial agent, and at least one of dispersing agent, antioxidant and light stabilizer. The antibacterial nylon fiber prepared by the invention hardly changes color in the processing and using processes, has excellent color change resistance, and has stable and durable antibacterial performance.
Description
Technical Field
The invention belongs to the field of preparation of antibacterial fibers, and particularly relates to a color-changing-resistant antibacterial polyamide fiber.
Background
With the increase of health importance of people, the antibacterial functional requirements are also put forward on the textiles, and the antibacterial effect of the textiles is mainly realized by the antibacterial fibers. The antibacterial fiber has antibacterial and bactericidal functions, can prevent infection and infection, and is widely used for home textiles, underwear, sport shirts and the like, in particular to clothes for the old, pregnant and lying-in women and infants. The clothes made of the fiber have good antibacterial performance, and can resist the attachment of bacteria on clothes, so that people can be far away from the invasion of germs. The antibacterial fiber's resistance to and killing of bacteria is not a one-time temporary effect, but rather a long-term effect of weeks to years. The long-term antibacterial property is realized because the built-in design is adopted, so that the antibacterial agent can be slowly dissolved out, a bacteriostatic ring is formed on the surface of the fiber, and even if the surface antibacterial agent is washed away, a new antibacterial agent overflows to form a new bacteriostatic ring. Therefore, clothes made of the fiber have good washing fastness. Currently, there are many research institutes around the world developing new antibacterial fibers, and artificial antibacterial fibers are generally achieved by post-finishing or in-situ addition. The after-finishing is prepared by soaking natural fiber with organic antibacterial agent such as quaternary ammonium compound or fatty imide, and can be used for hospital textiles such as clothes, bed sheet, cover cloth, curtain, panty-hose, socks, bandage, etc. The in-situ addition is obtained by mixing inorganic antibacterial agent with heat resistance such as ceramic powder containing silver, copper and zinc ions into polyester, polyamide or polyacrylonitrile for spinning. The in-situ addition has a larger market for better durability and washability. The antibacterial agents are divided into two categories, one is organic antibacterial agents such as quaternary ammonium salts and guanidines, and the other is inorganic antibacterial agents such as zeolite, silica gel, phosphoric acid and the like loaded with silver, copper, zinc ions and the like. Among them, silver ion antibacterial agents are highly effective antibacterial agents and very safe to human bodies, and are widely used for the production of antibacterial fibers.
The nylon is the second largest fiber with the second yield of terylene in chemical fiber, has good hygroscopicity and good affinity with human body, is used for underwear, swimwear, socks, woven belts and the like, and the silver ion antibacterial agent is also used in the nylon. However, chinlon using silver ion antibacterial agent is very easy to discolor in the process of processing and using. When the fiber is placed for too long time or the pH value of the environment changes, the fiber can generate color changes such as red, brown and the like, and the fabric can generate uneven color spots, color blocks and the like, thereby seriously influencing the application field of the antibacterial nylon fiber. The main reason for the discoloration is that the precipitation speed of silver ions in the supported antibacterial agent is too high, and particularly in a high-temperature and high-humidity environment, the precipitated silver ions generate colored compounds to cause color change of fibers or fabrics, and the discoloration phenomenon is particularly obvious in chinlon 6 or chinlon 66.
The invention patent CN00800536.2 in China adds magnesium aluminum hydrotalcite in the antibacterial composition, which can inhibit the discoloration of the plastic product containing silver-based antibacterial agent, and the hydrotalcite has low price, but the effect of the hydrotalcite in the textile is unknown. The Chinese invention patent CN2005100109965 provides an anti-tarnish inorganic antibacterial agent, which is prepared by dispersing silver-zinc mixed solution in silica gel solution, sintering to embed silver ions in crystal lattices, thereby reducing silver precipitation and oxidation, improving discoloration, and having good antibacterial property and anti-tarnish effect, but the preparation process is complex. In summary, an antibacterial agent with excellent performance or a simple process is lacked at present to enable the nylon fiber to have antibacterial performance and good discoloration resistance.
