1.5, hydrogen peroxide 2.1-2.5, stearoyl lactate 2.3-2.5, deionized water 62-68.
Further, the non-woven fabrics is molten by Capsaicin modification of chitosan acidity
Liquid impregnation the following steps are included:
(1) it uses mass fraction to impregnate 30min at room temperature for 10% ethanol solution non-woven fabrics, is then filtered, it is natural
It drains；
(2) treated non-woven fabrics is put into Capsaicin modification of chitosan acidity
In solution, it is heated to 60-64 DEG C, 35-40min is impregnated, then adjusts the temperature to 72 DEG C again, with frequency be 35kHz, power is
Then the ultrasonication 8-10min of 600W keeps the temperature again and stands 30min, then is filtered, using deionized water to filtered
Non-woven fabrics is cleaned to neutrality, and drying to constant weight.
Further, the Capsaicin modification of chitosan acid solution is by weight
Meter be made of following component: Capsaicin 0.12-0.15, chitosan 15-18, acetic acid 5-6,
Trimethoxy silane 0.1-0.2, deionized water 38-40.
Further, the starch is that soybean starch and job's-tears starch are mixed to get by 10:1 mass ratio.
Further, the composite modified nano-tourmaline powder, preparation method thereof the following steps are included:
(1) cyclodextrin that parts by weight are 10 parts is evenly spread in the solvent that mass parts are 50, is ultrasonically treated 15min, ultrasound
Power is 45kHz, is then heated to 78 DEG C, adds the maleic anhydride of its quality 1.2%, and into solution with 1300r/min revolving speed
Stirring 2 hours obtains reaction intermediate solution, then adjusts reaction intermediate solution pH to 5.2 using acetum, obtains acid reaction
Intermediate solution；
(2) chitosan that parts by weight are 2 parts is added into acid reaction intermediate solution obtained above, at 60 DEG C, with 500r/
Min revolving speed stirs 1 hour, and then adding parts by weight again is 4 parts of nano-tourmaline powder and 0.2 part of coupling agent, continues to stir
1.5 hours, then freeze-drying obtained composite modified nano-tourmaline powder.

The utility model has the advantages that the Capsaicin modification of chitosan acid solution that the present invention prepares
There is better fungistatic effect compared to common chitosan solution, through the invention the middle anti-8- methy-N-vanillyl -6- prepared
Nonenyl amide modifications chitosan acid solution, wherein active macromolecules can preferably adsorb bacterium, then pass through bacterium
Porous cell wall enters in bacterial cell, can form stable compound with DNA of bacteria, interfere DNA of bacteria polymerase or
The effect of RNA polymerase hinders the synthesis of DNA or RNA, to inhibit the breeding of bacterium；Bacteriostatic non-woven cloth prepared by the present invention
Adhesive tape has excellent fungistatic effect and antibacterial lasting effect, and the preferable bacteriostasis property present invention can be kept to pass through preparation for a long time
Composite modified tourmaline powder can be evenly dispersed in the adhesive of Non-woven tape, has long-acting fungistatic effect to bacterium,
The synergistic effect of the modified negative-ion and modification of chitosan that are issued by composite modified nano-tourmaline powder can occur with bacterium
Certain effect, so that the charge branch on bacteria cell wall and cell membrane is uneven, the synthesis of drying bacteria cell wall is broken
Cell wall synthesis and dissolution equilibrium under natural conditions again, meanwhile, promote bacteria cell wall to be intended to dissolve, so that bacterium
Cell membrane deforms splitting because that cannot bear osmotic pressure, intracellular content exudation, bacterolysis and it is dead, reached significant
Fungistatic effect also effectively extend antibacterial lasting effect, significant effect while fungistatic effect is greatly improved.
