How to choose the thickness of non-woven fabric

In the domestic disinfection supply center,except for cotton, the most commonly used packaging material is non-woven fabric. And the thickness of the hospital (ie the weight of gram) that the hospital often pays attention to when choosing non-woven fabrics, then the non-woven is not as thick as possible?

the answer is negative.

The increase in the thickness of the non-woven fabric(Medical Non Woven Fabric Manufacturer) means that the weight per unit area increases, and the corresponding strength also increases, but due to its own structural characteristics, the increase in thickness does not mean an increase in barrier properties. Microbes increase. For example, if a thickened nonwoven fabric isused, the weight of the spunbond layer does not effectively increase itsbacterial resistance. Only when the pore size of the critical filter layer (ie,the molten spray layer) can effectively filter the intrusion of micro organisms and dust, its bacterial resistance can meet the requirements. As the thickness increases, the breathability of the packaging material is also affected, andthe probability of wet packaging increases.

Clinically, the non-woven fabric will be damaged after sterilization. The damage is mainly caused by the shrinkage of the micro-fine plastic fibers after the high-temperature sterilization of the non-woven fabric, and the sterilization of the non-woven fabric(Composite SMS Non-woven Roll Supplier) is performed before sterilization. It is easy to become brittle, so it is too much or unreasonable to use it. The force will cause destructive damage to the packaging material. In addition to the use of burrs and sharp instruments onthe outer edge, it will cause the non-woven fabric to break. In this case, itis recommended that the clinical packaging should be properly tightened and handled with care, and the specifications of the two-layer packaging will greatly reduce the probability of damage. If the damage problem is solved only by increasing the thickness of the non-woven fabric, in addition to ensuringthe tolerance of the bacteria, the probability of closely watching the wet bag is also required.

In short, the choice of non-woven fabric(Medical Nonwovens Factory) is not as thick as possible. Under the premise of ensuring the pull resistance and tensile strength of the bacteria, the material with good gas permeability will reduce the wet bag phenomenon.
