Nonwovens - Things 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 two substances have similar names, they are quite different in chemical structure. . The chemical molecular structure of polyethylene is quite 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 be easily broken, so it can be effectively degraded , in general, it can be completely decomposed within 90 days. The reason for the decomposition is that the polypropylene fiber has poor light resistance, and it will easily become brittle 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 low-temperature plasma sterilization of hydrogen peroxide; non-woven fabric containing plant fibers cannot be used for low-temperature plasma because plant fibers will absorb hydrogen peroxide For sterilization, please refer to the manufacturer's instructions and test report for details.

3. Can a non-woven fabric be used in the under-exhaust sterilizer?

Non-woven fabrics are suitable for under-exhaust sterilization, but drying should be done well, because the humidity of under-exhaust sterilization is difficult to control, and non-woven wraps are very easy to wet.
