Problems solved by technology

[0004] There are two traditional methods for preparing catalytic fibers: one is the impregnation method. The catalyst required by the impregnation method must be a soluble chemical. The preparation process will cause air pollution. In addition, the catalytic fiber prepared by the impregnation method has a low soaping degree and can be Low reuse rate
Another method is the solution electrospinning technology. Polymers that are insoluble in organic matter cannot be spun, and insoluble inorganic particles must be soluble polymers loaded with inorganic particles before they can be directly spun with polymers. Complicated, and the mechanical properties of the fibers obtained by solution electrospinning are significantly reduced due to the appearance of holes on the surface of the solvent volatilization

Embodiment Construction

[0018] The parts indicated in the following examples all refer to parts by mass. Concentrations are all mass percent concentrations.

[0019] Example 1:

[0020] Add ZnO catalytic particles to absolute ethanol and stir at high speed for 1-2 hours, then heat and stir to 80°C to prepare ZnO suspension, add silane coupling agent accounting for 1% of ZnO particle mass fraction to ZnO suspension drop by drop In the liquid, continue to stir for 1-2 hours, filter and dry.

[0021] 100 parts of polypropylene, 20 parts of surface-treated ZnO catalytic particles, 0.3 parts of antioxidant 1010, and 15 parts of polyester plasticizer were fully mixed, and spun by melt electrospinning equipment (spinning temperature: 220 ° C, Spinning distance 12cm, spinning voltage 55kV).

[0022] Example 2:

[0023] Add ZnO catalytic particles to absolute ethanol and stir at high speed for 1-2 hours, then heat and stir to 80°C to obtain a ZnO suspension, add titanate coupling agent that accounts for 1...

Abstract

The invention relates to an antibacterial fiber and a preparation method thereof. The antibacterial fiber prepared by the invention comprises the following components of characteristic matters in parts by weight: 100 parts of a polymer, 10-50 parts of ZnO catalytic particles, 0.2-1.5 parts of coupling agent, 0.1-0.5 parts of antioxidant and 0-50 parts of plasticizer. The antibacterial fiber provided by the invention is not treated by toxic organic matters and is free from secondary pollution. The catalyst used is rich minerals, so that the antibacterial fiber is convenient for industrial production, low in cost and simple in preparation process. The utilization efficiency of an antibacterial agent is improved, the degerming rate is fast and the removal rate is high due to the antibacterial fiber. The antibacterial fiber is easy to weave and form and high in soaping degree and can be repeatedly used.

Description

technical field [0001] The invention relates to using melt electrospinning technology and inorganic particle-polymer coupling technology to load inorganic particles on polymer nanofibers to prepare antibacterial fibers so as to have high-efficiency antibacterial properties. Background technique [0002] Antibacterial agents commonly used in production are mainly divided into two categories: organic and inorganic. Organic antibacterial agents include a variety of traditional antibacterial agents, with acids, esters, alcohols, and phenols as the main raw materials; although they have strong antibacterial power and good immediate effect, they have shortcomings such as toxicity, poor safety, and easy migration (resulting in short antibacterial life) , In addition, its heat resistance is poor, it is easy to decompose and fail during processing, and the decomposed substances are even toxic, so the application range is narrow. Inorganic antibacterial agents and their products have...
