Problems solved by technology

Moreover, since cotton needs to add monomers such as polymethyl acrylate and acrylamide-vinyl acetate in the process of spinning into cloth, these monomers directly affect the further functionalization of cotton fabrics, such as affecting the functionalization of cotton fabrics. The loading efficiency and uniform distribution of ions make the functionalization of cotton fabrics more difficult than the functionalization of pure cotton fibers.

Embodiment 1

[0017] 5g of pure cotton cloth (containing 100% cotton), washed with distilled water, immersed in 50ml of 2% fatty acid polyoxyethylene ester solution by mass percentage, and taken out after 30min. AgNO at 0.1M 3 20% by mass of ammonia water was added to the solution to obtain a clear silver ammonia solution. Dip the soaked cotton fabric into 100ml silver ammonia solution, and heat at 40°C for 30min. After the reaction, wash the silver-loaded cotton fabric with distilled water, put it into 150ml of 1% glucose solution by mass percentage, wash the surface with distilled water after 60min, and dry it at 30°C. figure 1 SEM photos of silver-loaded pure cotton cloth, from figure 1 a It can be seen that silver is distributed evenly in the cotton fibers.

Embodiment 2

[0019] 5g nylon cotton (containing 75% cotton, 25% nylon), after washing with distilled water, immersed in 50ml 2% fatty acid polyoxyethylene ester solution by mass percentage, and took it out after 30min. AgNO at 0.3M 3 Add 25% ammonia water in the solution to obtain a clear silver-ammonia solution. Dip the soaked cotton fabric into 100ml of silver ammonia solution, and heat at 50°C for 45min. After the reaction, wash the silver-loaded cotton fabric with distilled water, put it into 150ml of 3% glucose solution by mass, wash the surface with distilled water after 60min, and dry it at 30°C. figure 1 For the SEM photo of silver-loaded brocade cotton, from figure 1 b It can be seen that silver is evenly distributed in nylon cotton fiber.

Embodiment 3

[0021] 5g of polyester cotton (33% cotton, 67% polyester), washed with distilled water, immersed in 50ml of 5% fatty acid polyoxyethylene ester solution by mass percentage, and taken out after 30min. AgNO at 1M 330% by mass of ammonia water was added to the solution to obtain a clear silver-ammonia solution. Dip the soaked cotton fabric into 100ml silver ammonia solution, and heat at 70°C for 35min. After the reaction, wash the silver-loaded cotton fabric with distilled water, put it into 150ml of 7% glucose solution by mass percentage, wash the surface with distilled water after 60min, and dry it at 30°C. figure 1 SEM photo of silver-loaded polyester cotton, from figure 1 c It can be seen that silver is evenly distributed in the polyester-cotton fiber.

Abstract

The invention discloses a sliver-carried antibacterial material which takes pure cotton cloth and cotton blended cloth such as brocade cotton, polyester cotton and cotton polyester in cotton fabrics as a basal body and a preparation method thereof, and belongs to the technical field of functional high polymer materials. Silver is uniformly distributed in fiber skeletons of the antibacterial cotton fabrics. The preparation method of the sliver-carried cotton fabric comprises the following steps: applying a nonionic surfactant to treat pure cotton cloth, the brocade cotton, the polyester cotton and the cotton polyester in the cotton fabrics, soaking in silver ammonia liquor, and applying a reducing agent to reduce after heating reaction is ended, so that the sliver is uniformly distributed in the fiber skeletons of the antibacterial cotton fabrics. The preparation method is simple and easy to control, gentle in reaction condition, short in time consumption, low in energy consumption, low-carbon and environment-friendly, and the applied reaction agent is low in toxicity and environment-friendly. After being carried with sliver, the silver-carried cotton fabrics can well resist escherichia coli and staphylococcus aureus.

Description

technical field [0001] The invention relates to a polymer antibacterial material, in particular to a silver-loaded cotton fabric antibacterial material, which belongs to the field of functional polymer materials. Background technique [0002] The function of antibacterial materials is mainly to inhibit or kill pathogenic bacteria and molds, and block the spread of diseases. Silver or silver ions have good antibacterial properties, which have been discovered by people in ancient times. For example, people used silver vessels to hold food to prevent mildew and rot. At the beginning of the 20th century, due to silver's good antibacterial and anti-infective properties, silver-based antibacterial materials were widely used in clinical medicine. At present, most silver-loaded antibacterial materials use certain carriers (such as silica gel, zeolite, activated alumina, zirconium phosphate, montmorillonite, hydroxyapatite, natural or chemical fibers, etc.) The surface of the carri...
