Embodiment 1

[0014] Add 50ml of polyethylene glycol into a 250ml three-necked flask, add 1.2g of silver nitrate, replace the oxygen in the bottle with high-purity nitrogen for 3 times under ultrasonic degassing, and react at 60°C for 3 hours to obtain nano-silver colloid. The prepared polymer stably dispersed nano-silver colloid is diluted, combined with a softener 508G to make a finishing solution, and the fabric is treated by padding to obtain an antibacterial fabric.

Embodiment 2

[0016] Add 50ml of polyethylene glycol into a 250ml three-necked flask, add 1.2g of silver nitrate, 0.4g of ascorbic acid, replace the oxygen in the bottle with high-purity nitrogen for 3 times under ultrasonic degassing, and react at 60°C for 3 hours. Dilute the nano-silver colloid with stabilized dispersion of the obtained macromolecules, combine softener 508G to make a finishing solution, and process the fabric through padding to obtain an antibacterial fabric.

Embodiment 3

[0018] Add 50ml of polyethylene glycol in a 250ml three-necked flask, add 1.2g of silver nitrate, 0.2g of tannic acid, replace the oxygen in the bottle with high-purity nitrogen for 3 times under ultrasonic degassing, and react at 30°C for 3 hours, and the The prepared polymer stably dispersed nano-silver colloid is diluted, combined with a softener 508G to prepare a finishing solution, and the fabric is subjected to padding treatment to obtain an antibacterial fabric.

Abstract

The invention discloses a ramie cotton fabric inorganic nanometer antibiosis finishing agent and a preparation method thereof. The invention is characterized that ascorbic acid, silver nitrate, polyethylene glycol are taken as raw materials for preparing nanometer Ag finishing liquid, in the finishing liquid, the average grain diameter of Ag is controlled to be 3-20nm. Due to the stabilizing effect of high polymer, dispersion stability of nanometer Ag is good and antibiosis effect is good even under light concentration. Antibiotic finish of Ag is carried out in the process of finishing of fabrics and nanometer Ag is combined with fiber to obtain the wash-resistant antibacterial fabric; the fabric has rapid, high-efficient, broad-spectrum and lasting antibiosis effect. The preparation method and finishing process are simple, the cost is low, no pollution is caused, and industrialization can be easily realized.

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, hygienic cleaning, maintenance of the fabric's own properties, including preventing fabric products from coloring, embrittlement and discoloration. It has attracted great attention from the business community and governments of various countries, and has broad application prospects. In order to obtain fabrics with excellent antibacterial properties, excellent antibacterial agents must be selected. Ag series antibacterial agent has antibacterial ability incomparable to other metals, and has good antibacterial effect on bacteria, fungi, and mold. It can achieve very good antibacterial effect, good durability, and is difficult to gather in the human body. ...
