Problems solved by technology

However, the macromolecular structure of polypropylene does not contain hydrophilic groups, and its crystallinity is very high. It has no antibacterial properties, resulting in poor hydrophilicity and antibacterial properties of polypropylene non-woven fabrics. Sex and antibacterial properties are not very good defects, which limit its application

Abstract

The invention discloses a preparation method of an antibacterial polypropylene fiber non-woven fabric for a wiping paper. The preparation method comprises: dispersing graphene oxide in dimethylacetamide, adding mercapto-succinic acid and anhydrous triethylamine into the solution for a reaction, carrying out aftertreatment to obtain a material A, dispersing the material A in dimethylacetamide, adding curcumin and p-toluenesulfonic acid into the solution for a reaction, carrying out aftertreatment to obtain modified graphene oxide, uniformly mixing sodium dodecylbenzenesulfonate, sodium lauryl sulfate, sodium phosphate, modified graphene oxide, carbon nanotubes, nano-silver, aloe extract and water to obtain an immersion liquid, immersing a polypropylene fiber non-woven fabric in the immersion liquid, carrying out drying to obtain the immersed non-woven fabric, adding 5, 5-dimethyl hydantoin into the aqueous sodium hydroxide solution, adding methanol and allyl bromide into the solution for a reaction to obtain a hydantoin derivative, uniformly mixing acrylic resin, hydroxyethyl acrylate, octadecyl acrylate, hydantoin derivative, a light initiator and ethyl acetate, immersing the immersed non-woven fabric into the mixed solution, and carrying out drying, curing, chlorination, washing and drying.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a method for preparing antibacterial polypropylene nonwoven fabrics for wiping paper. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which is formed by directly using polymer chips, short fibers or filaments to form fibers through airflow or mechanically, and then strengthened by hydroentanglement, needle punching or hot rolling, and finally finished. The non-woven fabric is a new type of fiber product with soft, breathable and planar structure. The materials of non-woven fabrics are polyester, polypropylene, nylon, spandex, and acrylic. Polypropylene non-woven fabrics are easy to handle, have good mechanical properties, good chemical stability, non-toxic, good air permeability, strong tensile strength, bending resistance, and wear resistance. And the advantages such as lower price, have been widely used at present. However, the macromole...
