Abstract

The invention belongs to the technical field of textile fabrics processing, and discloses an anti-wrinkle, anti-ultraviolet and antibacterial silk fabric and a preparation method thereof. The preparation method specifically comprises the following steps of step (1), performing plasma treatment on the silk fabric; step (2), mixing the defatted soybean flour and monopotassium phosphate with water, sterilizing and then inoculating microbial strains, stirring and fully fermenting the microbial strains, and filtering fermentation liquor, and ultrafiltering and concentrating the fermentation liquorto prepare an esterase preparation; and step (3), adding mellitic anhydride, graphite acid and the esterase preparation into methylbenzene to prepare a finishing suspension, putting the silk fabric subjected to the plasma treatment into the finishing suspension, ventilating and stirring, performing full impregnation reaction, washing and air-drying to obtain the anti-wrinkle, anti-ultraviolet andantibacterial silk fabric. The silk fabric has long-lasting and broad-spectrum antibacterial properties, is resistant to washing, and has excellent anti-ultraviolet effect, and while the anti-wrinkleperformance is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of textile fabric processing, in particular to an anti-wrinkle, anti-ultraviolet and anti-bacterial silk fabric and a preparation method thereof. Background technique [0002] Silk fabric is moisture-absorbing and breathable, light and smooth, has good elasticity, and has a good touch with the skin, but it is easy to wrinkle. The tryptophan and tyrosine in the silk fibroin of silk fabric can absorb ultraviolet rays, so it has better anti-ultraviolet function. However, after the silk fabric absorbs ultraviolet rays, it will undergo chemical changes, so that the silk fabric is prone to yellowing and the fiber strength decreases under the sunlight. In addition, silk fabrics are protein fibers on which microorganisms are easy to grow and multiply, so silk fabrics are in urgent need of antibacterial finishing. Silver ion and nano-silver antibacterial finishing have hereditary and reproductive toxicity to enviro...
