Abstract

The invention discloses a production method of an antibacterial degradable vinylon. The production method comprises the following steps of: dissolving polyvinyl alcohol, boric acid and nano complex copper having a solid content of 8-12% in hot water at a temperature in the range from 80 to 90 DEG C, thereby generating a plastic chelate as a spinning liquid; extruding the spinning liquid through a spinneret plate, and solidifying the extruded filaments in an alkaline solidification bath formed by sodium sulfate and sodiumhy droxide, thereby obtaining the vinylon filaments; blending an alcohol soluble vinylon filament oilingagent with the nano complex copper having the solid content of 8-12%, thereby obtaining an antibacterial spinning oiling agent; and applying the antibacterial spinning oiling agent to the vinylon filaments. The vinylon fibers produced by the method are integrated with antibacterial and degradable functions, so that the risk of infecting patients by pathogenicbacteria is reduced and also the vinylon fibers do not need to be disinfected and sterilized by high-temperature steam after being abandoned; besides, after use, vinylon non-woven fabrics can be completely degraded in hot water without being burnt; in other words, no secondary pollution can be caused; the antibacterial degradable vinylon has wide market development prospect.

Description

technical field [0001] The invention relates to the technical field of vinylon, in particular to an antibacterial and degradable vinylon and a preparation method thereof. Background technique [0002] Ordinary polypropylene and vinylon fibers are widely used in the manufacture of medical non-woven fabrics. They are used once and discarded after use. They are low in cost and easy to use. After they are discarded, they must be sterilized and sterilized with high-temperature steam, and the waste cannot be degraded by itself. Some non-woven fabrics have been antibacterially finished, which improves the antibacterial function of non-woven fabrics, reduces the risk of germs infecting patients, and improves the economic benefits of non-woven fabrics. However, this kind of non-woven fabric cannot be degraded by itself after being used and discarded. It must be incinerated and turned into general garbage, causing secondary pollution.
