At present, the common non woven fabric on the market can be divided into two categories, one is ordinary non woven fabric, the other is medical non woven fabric, because it is mainly used for medical treatment, so there are strict requirements for quality, what are the else differences between them?
1. Antibacterial ability
Since it is non woven medical fabric, the primary standard is antibacterial ability. Generally, SMMMS three-layer melt-spraying layer structure will be used, while ordinary non woven medical fabric uses single-layer melt-spraying layer structure. Compared with this, three-layer structure definitely has stronger antibacterial ability. As for non-medical non woven fabrics, because there is no melt-blown layer, does not have antibacterial ability.
2. Applicable to various sterilization methods
Since it has antibacterial ability, it also needs corresponding sterilization ability. High quality medical non woven cloth can be applied to a variety of sterilization methods, including pressure steam, ethylene oxide and hydrogen peroxide plasma. However, ordinary non-medical non woven fabrics cannot be applied to a variety of sterilization methods.
3. Quality control
Medical non woven fabrics all need to be certified by the relevant product quality control system, and there are strict standards and requirements for each step of the product in the production process.
The main differences between medical non woven fabrics and ordinary non woven fabrics are mainly reflected in these aspects, both have their own use and characteristics, as long as the right choice according to the needs in the use.
