Description

A kind of inorganic/organic nanocomposite antibacterial agent and its fiber product application

Technical field:

The invention relates to an inorganic/organic nano composite antibacterial agent, in particular to an inorganic/organic nano composite antibacterial agent with rapid antibacterial effect and long-lasting antibacterial performance and its application in fiber products.

Background technique:

Antibacterial refers to the effect of inhibiting and killing bacteria and other microorganisms, including bactericidal, bacteriostatic, sterilizing, disinfecting, mildew-proof, and anti-corrosion effects (New Functional Plastic Additives, Chapter 2, Antibacterial Agents, 2003: 25). Antimicrobial agents are substances that are extremely sensitive to microorganisms, and a very small amount can inhibit the growth of microorganisms and kill microorganisms. Antibacterial agents are applied to fiber products and can be processed to produce antibacterial fiber products. The antibacterial fiber product has the ability to kill microorganisms such as bacteria that it touches and adheres to the fiber fabric, and/or inhibit the growth and reproduction of microorganisms.

Antibacterial agents have been used by humans since ancient times. In the early days of our country, there were records of using plant soaking liquid to make antibacterial articles for antibacterial and disease prevention. In the Second World War, the German army reduced the bacterial infection of the wounded by wearing antibacterial uniforms, and began the practical application of modern antibacterial materials (Modern Industry 1998 (4): 54).

Antibacterial agents mainly include organic antibacterial agents, inorganic antibacterial agents, and natural antibacterial agents (including traditional Chinese medicine extracts). Most natural antibacterial agents are derived from natural organic compounds or natural minerals, so they can also be classified into organic antibacterial agents and inorganic antibacterial agents. Due to the different antibacterial mechanisms of various antibacterial agents, their antibacterial behaviors and effects are also different. For example, some antibacterial agents have quick-acting bactericidal effects, such as: iodine, alcohol, and ethylene oxide, so they are often used for disinfection and sterilization; some antibacterial agents have long-lasting antibacterial stability, and their persistence can last for several months , Several years to decades, such as triclosan, silver-loaded inorganic antibacterial agents, and zinc oxide, so they are used in the production of implantable antibacterial materials and products, such as antibacterial plastics and antibacterial ceramics.

Organic antibacterial agents generally have the advantages of rapid antibacterial effect and strong antibacterial power, but they have fast dissolution, short antibacterial validity period (poor durability), poor weather resistance, low antibacterial stability, and some antibacterial agents are more irritating to the skin. The antibacterial spectrum is narrow, and long-term application may also lead to the emergence of drug-resistant strains. Inorganic antibacterial agents are mostly inorganic compounds containing silver, zinc, and copper ions, which belong to the non-dissolution antibacterial mechanism. They have a long antibacterial period, a wide antibacterial spectrum, and little irritation to the skin. The higher the minimum inhibitory concentration value, the lower the antifungal efficiency. However, the nano-scale inorganic antibacterial agents developed rapidly in recent years have greater antibacterial power than ordinary inorganic antibacterial agents.

In many occasions in daily life, people need and hope to use safe and harmless fiber products with excellent antibacterial properties, such as underwear, bedding textiles, masks, carpets, etc. In addition, especially in hospitals and other places, antibacterial fiber products with strong antibacterial power, quick effect, durable antibacterial performance, washability, and high safety are good supplies to prevent nosocomial infections of patients and protect the health of medical staff.

When using antibacterial agents to prepare fiber products with antibacterial properties, the existing manufacturing methods mainly include the following two technical routes. 1. The antibacterial agent is melted (or dissolved) into the fiber polymer material during processing, that is, the antibacterial agent is blended into the fiber-forming polymer and retained in the polymer matrix. The types of fibers produced include antibacterial polypropylene ( Chinese invention patent 96118358.6 a kind of antibacterial polypropylene fiber and its manufacturing method), antibacterial polyester (Chinese invention patent application 01113772.X nanometer polyester staple fiber and its manufacturing method), antibacterial viscose fiber (Chinese invention patent 02160199.2 modified chitin -The manufacturing process and products of chitosan and viscose fiber spinning dope blend materials), known as spinning antibacterial technology, mainly used in the manufacture of antibacterial synthetic fibers. 2. Apply the antibacterial agent to the surface layer of the fiber, that is, penetrate into the surface layer of the fiber at a certain depth, or adhere to the surface of the fiber to keep it with the fiber, so that the fiber has a certain durable antibacterial property. Known as post-finishing antibacterial technology, it can be applied to almost all fiber products, including natural fiber products and synthetic fiber products (Chinese invention patent 01807542 is used for antibacterial agents and antibacterial textiles for fibers, 01815672.X Antibacterial treatment method for fiber materials, 02104252.7 Processing method and product of functional animal fiber knitted fluff products).

When the post-finishing antibacterial technology is used to prepare antibacterial fiber products, the easy loss of organic antibacterial agents leads to short antibacterial timeliness. Although increasing the amount of organic antibacterial agents can partially compensate for the lack of long-term antibacterial properties caused by the loss, it is accompanied by What comes is that an excessively high antibacterial dose poses a certain threat to human safety. Organic antimicrobials also have the disadvantage of gradual failure under ambient conditions. Inorganic antibacterial agents have a slow onset of action and generally need to act on bacteria for several hours to show antibacterial effects, which cannot meet the requirements of rapid sterilization.

It is not difficult to understand that it is possible to prepare high-performance antibacterial fiber products by using both inorganic antibacterial agents and organic antibacterial agents to give full play to their respective advantages. Chinese patent application 200410067284 discloses a composite nano-antibacterial agent for multi-component fiber products, the components of which include reactive organic antibacterial agents, nano-inorganic antibacterial agents, cationic dispersants, and distilled water. It is said that the underwear finished with the antibacterial agent formula has good antibacterial durability and washing resistance. After 100 times of washing, the antibacterial rate of antibacterial underwear after 24 hours of contact with Escherichia coli, Staphylococcus aureus and Candida albicans can reach 99.99% and 99% respectively. But this invention does not relate to the quick-acting antibacterial and bactericidal properties of the composite antibacterial agent and its antibacterial finishing fabric.

In addition, in order to maintain the long-term stable antibacterial performance of the finished fiber products during use, people have studied the use of adhesives to solve the problem of loss and shedding of antibacterial agents. However, the adhesive often weakens the antibacterial effect of the antibacterial agent, making the antibacterial performance of the antibacterial fiber fabric poor. This requires a comprehensive solution through a reasonable formula to keep the performance of the antibacterial agent well.

The present invention adopts the antibacterial finishing technology, utilizes the composite technology of inorganic antibacterial agent/organic antibacterial agent, and prepares a high-efficiency and quick-acting nano-composite antibacterial agent through a reasonable antibacterial agent formula, and then realizes the antibacterialization of fiber products, making fiber products both Excellent performance of antibacterial quick-acting and antibacterial lasting effect.

A - the average number of colonies of the blank control cloth;

B——The average number of colonies of the tested samples.

Judgment: If the antibacterial rate=50%～90%, the cloth sample has antibacterial effect; if the antibacterial rate≥90%, the cloth sample has strong antibacterial effect.

After determination, the antibacterial rate of 1# antibacterial cloth sample against Escherichia coli, Staphylococcus aureus and Candida albicans is shown in Table 1. Good antibacterial properties.

The antibacterial rate of 1# control antibacterial cloth sample to Escherichia coli, Staphylococcus aureus, and Candida albicans is shown in Table 2. slower.

The antibacterial rate of 2# control antibacterial cloth sample against Escherichia coli, Staphylococcus aureus, and Candida albicans is shown in Table 3. The newly prepared cloth sample has better antibacterial effects against Escherichia coli, Staphylococcus aureus, and Candida albicans.

The antibacterial effect of the antibacterial cloth sample and the control antibacterial cloth sample changes after washing, taking the test on Escherichia coli as an example, the antibacterial rate results are shown in Table 4-Table 7. The changes of Staphylococcus aureus and Candida albicans were similar.

After the lightfastness test of each cloth sample, the antibacterial rate against Escherichia coli is shown in Table 8. The changes of Staphylococcus aureus and Candida albicans were similar.

After the water resistance test of each cloth sample, the antibacterial rate against Escherichia coli is shown in Table 9. The changes of Staphylococcus aureus and Candida albicans were similar.

The 1#-30# antibacterial cloth samples treated with 1#-20# inorganic/organic nano-composite antibacterial agents showed strong antibacterial properties within 0-20 minutes (see Table 4), and played a rapid antibacterial effect. After washing, the antibacterial property decreases with the increase of washing times, but still maintains good antibacterial effect after 50 times of washing (see Table 5-Table 7). After the light fastness test, the antibacterial property is not weakened (see Table 8). After the water resistance test, the antibacterial property was not significantly weakened (see Table 9).

1#, 3#, 5#, 7# control antibacterial cloth (treated with 1# control inorganic antibacterial agent) before washing (see Table 4) and after washing (see Table 5-Table 7), the antibacterial effect is not strong within 20min . The action time is 18-24h, and the antibacterial effect is good. Comparing Table 4 with Table 5-Table 7, 1#, 3#, 5#, and 7# control antibacterial cloths have certain washing resistance. After the light fastness test, the antibacterial property weakened (see Table 8). After the water resistance test, the antibacterial properties decreased (see Table 9).

And 2#, 4#, 6#, 8# control antibacterial cloth (treated with 2# control organic antibacterial agent), the antibacterial effect is stronger before washing, and the time of action is faster. After washing, the antibacterial properties of the control antibacterial cloth samples 2#, 4#, 6#, and 8# were greatly attenuated. After the light fastness test, the antibacterial property decreased greatly (see Table 8). After the water resistance test, the antibacterial performance remained poor (see Table 9).
