The invention has the beneficial effects that:
1. the honeysuckle and forsythia PP spunbonded non-woven fabric adopts tyrosinase and a polymer with phenol residues to modify a honeysuckle extract, phenol is hydroxylated under the action of the tyrosinase to generate catechol, the catechol is obtained, the O-quinone is obtained through the oxidation of the tyrosinase, the O-quinone and proline undergo electrophilic addition to generate 4-N-prolyl-O-O-quinone, the proline addition product can continue to react with chitosan in a honeysuckle extracting agent to generate a chitosan derivative, the chitosan derivative can be dissolved at various concentrations under the acidic condition, the viscosity of the solution is remarkably improved along with the increase of the concentration, namely, the behavior characteristics of the associative thickener can be shown to form a physical cross-linked network structure due to interaction, the associative thickener can be mutually associated when interacting with chemical fibers, the storage time on the non-woven fabric is greatly prolonged, the detergent is not lost due to water washing.
2. According to the honeysuckle and forsythia PP spunbonded nonwoven fabric, due to the fact that the forsythia extract contains a large amount of phenethyl alcohol glycoside compounds, after the forsythia extract reacts with benzophenone, 2, 3, 4, 5 and 6 sites of central glucose are connected with groups, phenol with a benzene ring structure is replaced by hydroxyl or methoxyl in the benzophenone, and intramolecular hydrogen bonds can be formed between hydroxyl hydrogen on a benzene ring in the benzophenone structure and adjacent carbonyl oxygen to form a chelate ring. When ultraviolet light is absorbed, molecules generate thermal vibration, hydrogen bonds are destroyed, chelate rings are opened, the compound is in an unstable high-energy state, and redundant energy is released in the process of recovering to the original low-energy stable state. Thus, the high-energy harmful ultraviolet light becomes low-energy harmless heat energy. Meanwhile, carbonyl is excited to generate tautomerism, and the enol structure can consume a part of energy, so that the sun-screening and ultraviolet-resisting performances of the non-woven fabric are improved.

The PP spun-bonded non-woven fabric prepared by the invention has good antibacterial durability and sun-proof performance, and the specific detection is shown in the following table:
the test method comprises the following steps:
after 10 times of water washing, the PP spunbonded nonwoven fabrics prepared in the examples 1 to 9 and the comparative examples 1 to 3 are subjected to an antibacterial performance test through the standard of GB/T20944; the fabric sun protection performance is tested by a UV-2000 fabric sun protection index analyzer by using the standard of GB/T18830; carrying out color fastness test through GB18401-2003 national basic safety technical Specification of textile products; the data obtained are shown in table 1.
TABLE 1 Sterilization Rate and Sun protection Performance data for PP spunbonded nonwovens of examples 1-9 and comparative examples 1-3
The above data fully show that, compared with comparative examples 1-3, in examples 1-9 of the invention, because the honeysuckle flower and forsythia suspense PP spunbonded nonwoven fabric is modified by tyrosinase and the polymer with phenol residue, phenol is hydroxylated under the action of tyrosinase to generate catechol, which is catechol, and then is oxidized by tyrosinase to generate O-quinone, and electrophilic addition is performed with proline to generate 4-N-prolyl-O-quinone, the proline addition product can continuously react with chitosan of the honeysuckle flower extractant to generate chitosan derivatives, the chitosan derivatives can be dissolved in various concentrations under acidic conditions, and the viscosity of the solution is obviously improved along with the increase of the concentration, namely, the behavior characteristic of the associative thickener is shown to form a physical crosslinking network structure due to interaction, can be mutually associated when interacting with chemical fibers, greatly prolongs the storage time of the non-woven fabric, and does not run off due to external forces such as washing, thereby greatly improving the antibacterial and other functions of the prepared honeysuckle and forsythia PP spunbonded non-woven fabric.
Meanwhile, the prepared honeysuckle and forsythia PP spunbonded non-woven fabric contains a large amount of phenethyl alcohol glycoside compounds in the forsythia extract, after the forsythia extract reacts with benzophenone, 2, 3, 4, 5 and 6 sites of central glucose are connected with groups, phenol with a benzene ring structure is replaced by hydroxyl or methoxyl in the benzophenone, and intramolecular hydrogen bonds can be formed between hydroxyl hydrogen on a benzene ring in the benzophenone structure and adjacent carbonyl oxygen to form a chelate ring. When ultraviolet light is absorbed, molecules generate thermal vibration, hydrogen bonds are destroyed, chelate rings are opened, the compound is in an unstable high-energy state, and redundant energy is released in the process of recovering to the original low-energy stable state. Thus, the high-energy harmful ultraviolet light becomes low-energy harmless heat energy. Meanwhile, carbonyl is excited to generate tautomerism, and the enol structure can consume a part of energy, so that the sun-screening and ultraviolet-resisting performances of the non-woven fabric are improved.
In conclusion, the honeysuckle and forsythia PP spunbonded non-woven fabric prepared by the invention has advancement in sterilization rate and sun-screening performance, and meanwhile, the color fastness is also obviously reduced.
