Problems solved by technology

At present, there is no silk protein fiber with structural color, and the types of antibacterial fabrics are relatively single. Green environmental protection has gradually become the direction of textile fabric development. The development of green environmental protection, bright colors, hard to fade and antibacterial fabrics imperative

Embodiment 1

[0026] Polystyrene microspheres, polymethyl methacrylate microspheres and titanium dioxide microspheres were dispersed in water to prepare a colloidal emulsion with a mass fraction of 6%, and the mass ratio of the three was 2:2:1.

[0027] Cut a certain amount of cocoons into about 1cm 2 The fragments were added to the boiling 1wt% NaOH aqueous solution, and after boiling for 30 minutes, the degummed silk was rinsed with deionized water until the sericin was completely removed. After the degumming is complete, the silk fibroin is dried in an oven at 40°C. Weigh a certain amount of degummed silk, add it at a bath ratio of 1:10 and completely soak it in a container filled with 5M LiBr solution, and then keep the container at 60°C for one hour. Then put the solution into a dialysis bag with a molecular weight cut-off of 7000 and dialyze for three days to obtain the silk protein aqueous solution. Adding carboxymethyl cellulose and lanthanum chloride into the silk protein aqueous...

Abstract

The invention relates to a preparation method of antibacterial structural color fibers based on silk protein. The preparation method comprises the following steps: dispersing colloidal microspheres inwater to prepare colloidal emulsion with mass fraction of 6 to 15 percent, wherein the colloidal microspheres are polystyrene microspheres, polymethylmethacrylate microspheres and titanium dioxide microspheres; dissolving the silk protein, cellulose and rare earth elements in an aqueous solution of alkali, and carrying out electrostatic spinning to obtain silk protein fibers; enabling the silk protein fibers to pass through the colloidal emulsion in a lifting way from bottom to top; drying moisture by airing. The invention also provides an antibacterial structural color fabric based on the silk protein. The antibacterial structural color fabric comprises a base fabric layer and an antibacterial coloring layer, wherein the base fabric layer is formed by weaving warp yarns and weft yarns; all weft yarns are connected between every two adjacent warp yarns in an inclined manner; at least one of each warp yarn and each weft yarn is used as a wrapping yarn; the wrapping yarns are prepared from silks and bast fibers; the bast fibers are core yarns; the silks cover the surfaces of the bast fibers; the antibacterial coloring layer is prepared from the antibacterial structural color fibersbased on the silk protein.

Description

technical field [0001] The invention relates to the technical field of fiber preparation, in particular to the preparation of an antibacterial structural color fiber based on silk protein and an antibacterial structural color fabric. Background technique [0002] Structural color is a physical phenomenon. The appearance of color is produced by the interaction between the microstructure of the reflector and light, which only reflects light of a certain wavelength and transmits light of other wavelengths. The microstructure of the reflector is usually a three-dimensional periodic heterogeneous array structure, and the scale of its period is the same order of magnitude as the wavelength of the light it responds to. Objects with this structure are called photonic crystals. Natural opals in nature, bird feathers and insect beetle wings all have a photonic crystal structure, so they can also display colorful colors. The generation of structural color avoids the participation of c...
