Is It Better To Choose Nonwoven Fabric As Thicker As Possible?

The answer is negative.

An increase in the thickness of the Non Woven Fabric means an increase in the weight per unit area. The corresponding strength will also increase, 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 nonwoven 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 Filter Material layer ) can effectively filter the invasion of microorganisms and dust, its resistance 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 Roll will be damaged after sterilization. For this kind of damage, the main reason is that the microscopic fine plastic fibers will shrink to a certain extent after the non woven fabric is sterilized by high temperature. The performance is that the Filter Fabric after sterilization is more brittle than before sterilization. Therefore, applying too much force or unreasonable pick - and - place method to it during use will cause destructive damage to the packaging material. In addition, the use of burrs and sharp instruments on the edge will also cause damage to the nonwoven 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 nonwoven fabric, in addition to ensuring the antibacterial performance, it is also necessary to closely observe the probability of wet packs.
