Problems solved by technology

Natural antibacterial agents mainly come from natural extracts, and the antibacterial effect is not obvious; organic antibacterial agents are mostly various complex compounds containing nitrogen, sulfur, chlorine and other elements, and their main varieties are: quaternary ammonium salts, biguanides, alcohols, Phenols, aldehydes, organic metals, pyridines, thiophenes, etc. These antibacterials have obvious bactericidal effects in a short period of time, but their stability is poor. Not resistant to washing, short service life, certain toxicity and volatility, easy to cause skin and eye irritation

Embodiment 1

[0018] Add 50-200mL polyethylene glycol to a 250mL three-necked flask, add 1.2-2.0g of silver nitrate, 0.4-0.5g of tartaric acid, and replace the oxygen in the bottle with high-purity nitrogen for 3-5 times under ultrasonic degassing. React for 3 hours to get 200mL nano-silver colloid, dilute the obtained nano-silver colloid with stable polymer dispersion into 40L of water, combine softener 508G 1200g to make finishing solution, and apply padding treatment to 10×2.4m fabric , the scrapping rate is 65%, and the tenter drying temperature is 100-120°C to obtain the antibacterial fabric.

Embodiment 2

[0020] Add 50-200mL polyethylene glycol to a 250mL three-neck flask, add 1.2-2.0g silver nitrate, 0.4-0.5g ascorbic acid, and replace the oxygen in the bottle with high-purity nitrogen for 3-5 times under ultrasonic degassing, at 60°C After reacting for 3 hours, the nano-silver colloid of the stable dispersion of the prepared polymer was diluted into 40L of water, combined with softener 508G 1200g to make a finishing solution, and the 10 * 2.4m fabric was treated by padding, and the excess rate was 65%. , The tenter drying temperature is 100-120°C to obtain antibacterial fabrics.

Embodiment 3

[0022] Add 50-200mL polyethylene glycol to a 250mL three-necked flask, add 1.2-2.0g of silver nitrate, 0.2g of tannic acid, and replace the oxygen in the bottle with high-purity nitrogen for 3-5 times under ultrasonic degassing. Reaction 3 hours, the nano-silver colloid that the macromolecule stable dispersion that makes is diluted in the water of 40L, is made into finishing liquid in conjunction with softening agent 508G 1200g, and 10 * 2.4m fabrics are processed through padding, and the excess rate is 65%, The tenter drying temperature is 100-120°C to obtain the antibacterial fabric.

Abstract

The invention discloses ramie cotton fabric inorganic nanometer antibacterial finishing agent and a preparation method thereof. Silver nitrate and micro-molecular organic or inorganic reducing agent, such as ascorbic acid, tannic acid, tartaric acid and the like, are added into polyethyleneglycol and the mixture engages in deoxidization under 5-100 DEG C, producing nanometer silver with good dispersivity and stability. The polyethyleneglycol accounts for 50-90%of the weight and the ratio of silver salt to micro-molecular reducing agent is 1:1-4:1. The prepared nanomemter silver is dispersed in aqueous medium so as to get nanometer silver finishing agent and the weight percentage of nanometer silver is 0.25%-0.5%. The ramie cotton fabric can be made into composite material with excellent antibacterial effect after being soaked in the finishing agent. The fabric made from the antibacterial finishing agent has the characteristics of quick, efficient, broad-spectrum and lasting antibacterial effect. The preparation method and the finishing process are simple in technique and low in cost and have no pollution and are easy to industrialize.

Description

technical field [0001] The invention relates to an inorganic nano-antibacterial finishing agent for cotton and linen fabrics and a preparation method thereof, belonging to the field of nano-materials and technologies. Background technique [0002] Antibacterial fabrics have the advantages of blocking the spread of diseases, keeping clean and hygienic, maintaining the performance of fabrics themselves, including preventing fabric products from coloring, embrittlement and discoloration, etc., and have broad application prospects. The key to obtaining fabrics with excellent antibacterial properties lies in the selection of excellent antibacterial agents. The types of antibacterial agents have developed from the initial natural antibacterial agents to organic compound antibacterial agents, then to polymer antibacterial agents, and then to inorganic nanoscale antibacterial agents. Natural antibacterial agents mainly come from natural extracts, and the antibacterial effect is not...
