The product such as rope and sealing packing.Aramid fiber structure has core-skin two layers, and the high strength and modulus of aramid fiber is mainly by internal high knot
Brilliant sandwich layer determines, and aramid fiber is in application process, particularly in some moist or outdoor exposure application environments, aramid fiber material
Be easy in material it is mouldy, after mould largely assembles can aramid fiber silk is caused to damage, so as to reduce the production that it is applied
The quality of product.Therefore, people when producing aramid fiber, it is necessary to carry out antimildew and antibacterial processing to it, it is a kind of in traditional processing mode
It is to add antiseptic in aramid fiber spinning process, antiseptic is incorporated in aramid fiber silk, the technique of this mode is relative complex,
Cost is higher, simultaneously as antiseptic is present in the inside of aramid fiber, understands the regularity between saboteur, influences aramid fiber
Crystallization, greatly reduce the tensile strength of aramid fiber；Another kind be by chemically react in aramid fiber surface grafting antiseptic, and this
Processing time needed for kind mode is longer, and cost is also higher, while is grafted antiseptic and generally requires by ray radiation or chemistry
Method makes aramid fiber surface produce more active group, is grafted to by antiseptic on aramid fiber, this course of reaction can be to aramid fiber
It can affect greatly, be greatly reduced the tensile strength of aramid fiber.
The content of the invention
It is an object of the present invention to provide a kind of method for rapidly and efficiently lifting aramid fiber antimildew and antibacterial.The present invention has

Beneficial effects of the present invention：The present invention need to only be cleaned up aramid fiber using ethanol solution, be dried, then will drying
Aramid fiber be immersed in the mixed solution of zinc chloride and ethanol, and be ultrasonically treated with ultrasonic processor, finally use deionization
Water is cleaned and dried, technique very simple, time-consuming very short, is accelerated processing speed, is reduced production cost, meanwhile,
Because the price of zinc chloride and ethanol raw material is relatively cheap, cost reduce further.
In addition, compared with prior art, the zinc ion in zinc chloride ethanol solution of the invention can be with the carbonyl on aramid fiber surface
Complexing occurs for base, amino, and under ultrasonication effect, generation complex compound is recrystallized along zinc ion complexing position.
This processing will not damage the sandwich layer of aramid fiber, therefore aramid fiber intensity will not be caused too big just for the surface treatment of aramid fiber
Damage；Simultaneously when bacterium mould and this complex thereof, the zinc ion of free positively charged can attract bacterium, zinc ion production
Raw oligodynamic effect, destroying enzymatic activity makes protein coagulating have the function that antibacterial and mouldproof.
To further illustrate beneficial effects of the present invention, applicant has done following experiment：
