Problems solved by technology

Its disadvantages: it is not suitable for post-processing of textile decorative fabrics
Its shortcomings: the antibacterial property of the fabric itself is used to achieve the antibacterial effect on the harmful microorganisms of the textile fabric. It already contains harmful microorganisms, so it cannot achieve antibacterial effect at all

Embodiment 1

[0017] Embodiment 1: A kind of preparation method that is used for the antibacterial agent of textile decorative fabric, in the 100mL four-necked flask that thermometer, reflux condenser and stirrer are housed, after the silane of 1: 1.5~3, tertiary amine are mixed, add 0.15%~3% catalyst sodium iodide and 1.2%~2.5% antioxidant, add organic solvent at the same time, pass nitrogen protection, control the system at 65~80°C, stir and react, after the reaction is completed, cool and discharge to obtain a light yellow liquid Antibacterial finishing agent, its reaction equation is as follows:

[0018]

[0019] The organic solvent is mixed with methanol and dimethyl sulfoxide in a ratio of 4-2.5:1, the dosage is 30-40%, the reaction temperature is 65-80°C, and the reaction yield can reach more than 80% after 48 hours of reaction.

Embodiment 2

[0020] Example 2: On the basis of Example 1, after mixing 1:1.5 silane and tertiary amine, 0.15% catalyst sodium iodide and 1.2% antioxidant were added.

Embodiment 3

[0021] Example 3: On the basis of Example 1, after mixing 1:3 silane and tertiary amine, 3% catalyst sodium iodide and 2.5% antioxidant were added.

Abstract

The invention relates to a method for preparing antibacterial agent achieving the antibacterial effect on textile finishing fabric. The method comprises the following steps: mixing silane and tertiary amine by the ratio of 1:1.5-3 in a 100mL 4-neck flask equipped with a thermometer, a reflux condensation tube and a stirrer; adding 0.15%-3% sodium iodide as a catalyst and 1.2%-2.5% antioxidant as well as organic solvent at the same time to the mixture; feeding in protective nitrogen; controlling the temperature of the reaction system within 65 to 80 DEG C; stirring and reacting; and cooling and discharging after the reaction to obtain the light yellow liquid antibacterial finishing agent, wherein the reaction equation is shown as below.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial agent for textile decorative fabrics with antibacterial function, which belongs to the field of textile decorative fabric manufacturing. Background technique [0002] CNCN1568704A, title "a composite nano-antibacterial material and its preparation method and product", 1. Aiming at the deficiency of a single nano-antibacterial material, a nano-combined antibacterial technology was used to combine antibacterial materials with different antibacterial effects to prepare a composite nano-antibacterial material. The synergy and coupling between nanoparticles greatly improve the antibacterial ability; 2. The antibacterial material developed by this method has a broad-spectrum antibacterial function, and it is effective against Staphylococcus aureus, pathogenic Escherichia coli, Neisseria gonorrhoeae, syphilis, etc. A variety of germs (poisons) have a good killing effect; 3. The method can be us...
