Abstract

The invention discloses a preparation method of an antibacterial anti-flaming protein viscose fiber. The preparation method comprises the following steps of preparing fire retardant slurry, a protein glue liquid and a chitosan solution, mixing uniformly the fire retardant slurry, the protein glue liquid and the chitosan solution with a viscose spinning solution before spinning, preparing the antibacterial anti-flaming protein viscose fiber through wet spinning, and carrying out soft arrangement on the prepared fiber. According to the preparation method of the antibacterial anti-flaming protein viscose fiber, disclosed by the invention, the antibacterial anti-flaming protein viscose fiber is prepared from hexaphenoxy cyclotriphosphazene as a fire retardant, alkyl polyglycoside as an emulsifier of the fire retardant, animal protein as a protein raw material, and chitosan as an antibacterial agent, has excellent flame retardant property and is up to the national textile anti-flaming standard; and meanwhile, the service performance and antibacterial property are excellent, the wet strength of the fiber is improved by more than 20%, the initial modulus is reduced by more than 30%, and the bulking intensity is improved by more than 8%.

Description

technical field [0001] The invention belongs to the technical field of textile fibers, and relates to a preparation method of viscose fiber, in particular to a preparation method of composite viscose fiber having antibacterial and flame-retardant properties. Background technique [0002] Viscose fiber has some properties very similar to cotton fiber, such as good hygroscopicity, easy dyeing, antistatic, easy textile processing, etc. The fabric made of it has bright colors and is comfortable to wear, especially suitable for hot climate areas. Wearing, and the fineness and length of viscose fiber can be adjusted according to the requirements of the use, so it is welcomed by people. [0003] The biggest disadvantage of viscose fiber is that it is easy to burn. Ordinary viscose fiber burns directly after contacting the flame, and continues to burn after being removed from the fire source. The burning speed is fast and there is little ash left after burning. The flammability of ...
