The invention discloses an antibacterial finishing agent, an antibacterial yarn and a preparation method and application of the antibacterial yarn. The antibacterial finishing agent is prepared from the following components in parts by weight: 5-20 parts of antibacterial agent, 5-25 parts of a cationic colouring stabilizer, 10-30 parts of a cationic softener and 10-30 parts of water-based resin, wherein the antibacterial agent is selected from at least one of N-dodecyl-amino glycine betaine-2-cysteamine hydrochloride, 3-trimethoxysilylpropyl octadecyldimethyl-ammoniu chloride, chitosan biguanidine hydrochloride, polyhexamethylene biguanidine hydrochloride and ammonium dihydrogen phosphate; and the water-based resin is selected from at least one of vinyl acetate emulsion resin, polyvinyl alcohol resin, polymethylacrylic acid and polyethylene oxide. The water-based resin adopting the components is capable of improving the hand feeling and the comfort of the yarn; and through common action of the cationic colouring stabilizer, the cationic softener, the water-based resin and the antibacterial agent at the ratio, the yarn has good antibacterial property, the requirements of performance, such as the color fastness and the hand feeling comfort are coordinated, and meanwhile, the antibacterial property, the color fastness and the comfort of the yarn are ensured.

The invention discloses a method for preparing a hemostatic material based on an air jet pulverization technology. The method comprises the following steps of (1) preparing a fibrinogen solution, wherein the fibrinogen solution comprises the following components of 2.5-3.5 wt% of fibrinogen, 10-25 wt% of trehalose, 2-10 wt% of glycine, 1.0-1.5 wt% of sodium chloride, 0.1-0.6 wt% of sodium citrate, 2.0-2.5 wt% of arginine hydrochloride and the balance of water for injection; (2) performing freeze drying on the fibrinogen solution, and performing air jet pulverization to obtain fibrinogen powder; (3) preparing a thrombin solution, wherein the thrombin solution is prepared from the following components of 0.1 to 0.5 weight percent of thrombin, 1.5 to 5.0 weight percent of trehalose, 0.3 to 1.0 weight percent of calcium chloride, 0.5 to 2.0 weight percent of glycine, 1.0 to 3.0 weight percent of cane sugar, 0.5 to 2.0 weight percent of dextran 20 and the balance of water for injection; (4) performing freeze drying on the thrombin solution, and performing air jet pulverization to obtain thrombin powder; and (5) mixing the fibrinogen powder with the thrombin powder, filling and drying to obtain the hemostatic material. The preparation process is simple, the period is short, and the prepared material is convenient to clinically use and excellent in hemostatic effect and has a wider application prospect.
