Abstract

The invention discloses an in situ-based production method of an antibacterial ribbon. The method comprises the following steps: allowing cotton fibers to enter sodium periodate in order to obtain oxidized cotton fibers, impregnating the oxidized cotton fibers in polyethyleneimine to obtain polyethyleneimine grafted cotton fibers, allowing the polyethyleneimine grafted cotton fibers to enter silver nitrate in order to prepare antibacterial cotton fibers, and carrying out normal ribbon interlacing to obtain the antibacterial ribbon. The antibacterial ribbon produced through the method has very good soaping resistance and highly-efficient and lasting antibacterial property, still keeps the sterilization rate at 95-100% after 30 time washing, has no destroys to the self structure of the ribbon, and is widely applied; and the production method is simple.

[0021] The method for preparing an antibacterial webbing based on in-situ disclosed in the present invention includes the following steps:

[0022] a. Put the cotton fiber in a sodium periodate solution with a concentration of 0.1g/L to prevent light and oxidize for 200 minutes, at a reaction temperature of 80°C, and a bath ratio of 1:50 to obtain oxidized cotton fiber;

[0023] b. Immerse the oxidized cotton fiber in a polyacetimide solution with a concentration of 6g/L at a reaction temperature of 60°C and a bath ratio of 1:50 to obtain a polyacetimide grafted cotton fiber;

[0024] c. The polyacetimide grafted cotton fiber obtained after the step is immersed in a silver nitrate aqueous solution with a concentration of 0.15 mol/L at a bath ratio of 1:60, and reacted at 35°C for 14 hours. The silver nano-particle load is formed, washed with deionized water and absolute ethanol three times in sequence, and dried in vacuum at 40°C for 6 hours to obtain antibacterial cotton fiber;

[0025] d. Using a warping machine, twist the twisted 66'40D/12F*2 high-elastic nylon, antibacterial cotton fiber, and twisted 40D/12F high-elastic nylon to the pan head respectively;

[0026] e. Turn on the jacquard machine to interweave the embryonic belt, where the twisted 66'40D/12F*2 high elastic nylon and cotton fiber blend is used as the warp, the blending ratio is 1:2, and the 40D/12F high elastic nylon is twisted as the weft to control the jacquard The machine speed is 700r/min;

[0027] f. Dip the interwoven embryonic strip into a dye solution with environmentally friendly emulsion-like modified acrylate additives for dyeing. Soak for 5 minutes at 30°C, wash at 80°C for 5 minutes, and then wash at 115°C 5min;
