In the domestic disinfection supply center, besides cotton cloth, the most commonly used packaging materials are non-woven fabrics. However, when hospitals choose non-woven fabrics, they often attach great importance to thickness (ie weight), so is the thicker non-woven fabrics better? The non-woven fabric manufacturer tells you the answer is no.

The addition of the thickness of the non-woven fabric means the addition of the weight per unit area, and the corresponding strength will also be added, but due to its own structural characteristics, the addition of the thickness does not mean the addition of the isolation function of microorganisms. For example, when a thick non-woven fabric is used, the addition of the weight of the spunbond layer cannot effectively add its anti-bacterial function. Only when the pore size of the key filter layer (ie the melt blown layer) can effectively filter the intrusion of microorganisms and dust The bacteria function meets the requirements. The increase in thickness will also affect the air permeability of the packaging material and increase the probability of wet packs.

In clinical use, the non-woven fabric will be damaged after sterilization. For this type of damage, the main reason is that the microscopic fine plastic fibers of the non-woven fabric will shrink to a certain degree after high temperature sterilization. The performance is sterilization in use. The non-woven fabric after sterilization is more brittle than before sterilization, so applying too much force or unreasonable picking and placing method to it during use will cause destructive damage to the packaging material. Other applications have burrs and sharp edges. The equipment will also cause damage to the non-woven fabric. Under this circumstance, it is recommended that the clinic should be elastic and fit, handle with care, and use the double-layer packaging recommended by the standard, which will greatly reduce the probability of damage. If the problem of damage is solved only by increasing the thickness of the non-woven fabric, in addition to ensuring the anti-bacterial function, it is also necessary to closely observe the probability of wet packs.
