Antibacterial nano after-finish agent for knitted fabrics and preparation method thereof

Abstract

The invention provides an antibacterial nano after-finish agent for knitted fabrics and a preparation method thereof. In terms of mass percentage, the antibacterial nano after-finish agent for knittedfabrics includes the following components of nano-scale antibacterial coating agent 4.5% to 7.5%, titanium dioxide hydrosol 7% to 12%, metal-loaded composite mineral powders 2% to 4. 5%, coupling agent 1% to 4%, and curing agent 1% to 4%, and the balance is water. The antibacterial nano after-finish agent for knitted fabrics has reasonable raw material selection, uses the titanium dioxide hydrosol as the jointing basis, and uses the nano-scale antibacterial coating agent and metal-loaded composite mineral powders as effective antibacterial ingredients; therefore, the overall antibacterial effect is good, the structure is uniform and stable, the film formation is good, the adhesion to the knitted fabric fiber is strong, the chemical crosslinking effect is good, and the reagent fastness issignificantly improved; and meanwhile, the antibacterial nano after-finish agent for knitted fabrics has excellent ultraviolet resistance, good sun protection effect, and fragrant and refreshing effect, and the fabric protection period is prolonged significantly.

Description

technical field [0001] The invention relates to the technical field of fabric finishing, in particular to an antibacterial nano finishing agent for knitted fabric and a preparation method thereof. Background technique [0002] Finishing is a treatment method commonly used in clothing production. Finishing can give fabrics color effects, shape effects and practical effects. Clothing finishing is to improve the appearance and feel of fabrics, improve clothing performance or endow fabrics with chemical or physical methods. The process of special functions is the process of "icing on the cake" of clothing. Garment finishing is developing in the direction of functionalization, differentiation, and upscale of products, and focuses on improving product performance and increasing added value of products. For example, in order to improve the antibacterial effect of clothing, nano antibacterial finishing can be carried out on clothing. [0003] The nano-finishing of clothing is an i...

Problems solved by technology

[0005] However, the current treatment process obviously has the following defects: one is that the treatment effect lacks persistence, the reagents are not strong enough to perform nano-antibacterial finishing on knitted garments, and the washing resistance is very poor; the other is that the reagents are evenly dispersed in knitted garments poor performance, it is easy to produce uneven reagent plaques, which seriously affects the appearance of knitted garments and the finishing effect; third, most reagents contain formaldehyde and other substances, which are harmful to the human body and greatly affect the application in clothing finishing

[0007] The above-mentioned prior art combines two forms of impact + spray to improve the combination effect of the finishing agent and the fabric. Compared with the existing simple dipping or spraying, the overall quality is obviously better, but during the impact process, there are still uneven surface layers, Impact loss and large differences in local reagent concentration caused by uneven water wave transmission during impact
