Non-woven fabric-something you don't know

1. Is the non-woven fabric degradable?


In terms of environmental protection, the raw material of most of the non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , Generally speaking, it can be completely decomposed within 90 days. The reason for the decomposition is that the polypropylene fiber has poor light resistance and will easily become embrittled and become dust under ultraviolet radiation.


2. Are all non-woven fabrics suitable for low-temperature plasma sterilization?


All-plastic non-woven fabric (PP material) can be used for hydrogen peroxide low-temperature plasma sterilization; non-woven fabrics containing plant fibers can not be used for low-temperature plasma sterilization because plant fibers absorb hydrogen peroxide. For details, please refer to the manufacturer's instructions and test reports.


3. Is it possible to use non-woven fabrics for the lower exhaust type sterilizer?


Non-woven fabrics are suitable for under-exhaust sterilization, but it is necessary to do a good job of drying, because under-exhaust sterilization humidity is difficult to control, and non-woven wrapping is very easy to wet.
