In the domestic disinfection supply center, the most commonly used packaging materials besides cotton are non-woven fabrics. Hospitals often pay attention to thickness (ie gram weight) when choosing non-woven fabrics. Is the thicker the non-woven fabric the better? The answer is no.
The increase in the thickness of the non-woven fabric 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 the barrier properties of microorganisms. For example, when a thickened non-woven fabric is used, the increase in the weight of the spunbond layer cannot effectively increase its antibacterial performance. Only when the pore size of the key filter layer (ie, the meltblown layer) can effectively filter the invasion of microorganisms and dust, its resistance to Bacterial properties meet the requirements. As the thickness increases, the air permeability of the packaging material will also be affected, and the probability of wet packs will also increase.
In clinical use, the non-woven fabric will be damaged after sterilization. For this kind of damage, it is mainly because the micro-fine plastic fibers of the non-woven fabric will shrink to a certain extent after high temperature sterilization, which is manifested in the use of sterilization. The non-woven fabric is more brittle than before sterilization, so applying too much force or unreasonable handling methods during use will cause destructive damage to the packaging material. In addition, the use of burrs on the edges and sharper instruments It will also cause damage to the non-woven fabric. In this case, it is recommended that the clinical package should be tightly packed and handled with care, and use the double-layer packaging recommended by the standard, which will greatly reduce the probability of damage. If the problem of breakage is only solved by increasing the thickness of the non-woven fabric, in addition to ensuring the antibacterial performance, it is also necessary to closely observe the probability of wet packs.
