The difference between medical non-woven fabrics and ordinary non-woven fabrics

The common types of non-woven fabrics on the market can be mainly divided into two types, one is general non-woven fabrics, and the other is medical non-woven fabrics. Because they are mainly used in medical treatment, they have strict quality control. What are the differences between the two? Let's take a look with Xinyu Non-woven.

1. Antibacterial ability

Since it is a medical non-woven fabric, the primary standard is the antibacterial ability. Generally, the smmms three-layer meltblown layer structure is used, and the general medical non-woven fabric is used It is a single-layer meltblown layer structure. Compared with the two, it must be that the three-layer structure has stronger antibacterial ability. As for non-medical general non-woven fabrics, because there is no meltblown layer, it does not have antibacterial ability.

2. Applicable to a variety of sterilization methods

Since it has antibacterial ability, it also needs corresponding sterilization ability, high-quality medical non-woven fabrics can be applied to a variety of sterilization methods , there are three common sterilization methods: pressure steam, ethylene oxide, hydrogen peroxide and plasma. And general non-medical non-woven fabrics cannot be applied to a variety of sterilization methods.

3. Quality control

Non-woven packaging materials are generally SMS composite non-woven fabrics. The main raw material of this type of non-woven fabric is polypropylene, which is processed through multiple processes through melt-blown and spunbond processes. The microstructure is fine plastic fibers. It is the characteristic of plastic articles that it shortens when exposed to high temperature. There is no plastic, and high temperature resistance is also a relative concept, so the non-woven fabric will also have a corresponding shortening response on the microscopic level.
