Most non woven products are disposable products. What are the reasons for not being able to reuse them? Below we will explain to you in detail.

1. Sterile barrier performance is lost after use

According to research, the shelf life of sterile articles is closely related to the thickness of the non woven fabric(China Nonwovens Products Supplier) and the number of layers of the cloth. Disposable non woven packaging materials, after a series of high-temperature steam sterilization and chemical washing, the fiber structure is deformed, the pores are sparse, the thickness is reduced, and even the small holes that are not easily noticeable to the naked eye, the bacteria inhibition rate will suddenly drop or loss of bacteria resistance. The requirements for packaging materials in the Disinfection Technical Specification are: to provide a bacterial barrier during storage to maintain sterility. If the device is packaged in a single-use packaging material, the storage after sterilization cannot be safely valid.

2. Internal microscopic properties change after sterilization

The non woven packaging material is generally an SMS composite type non woven fabric. The main material of this type of non woven fabric(Non Woven Products On Sales) is polypropylene, which is processed through multiple processes through melt-blown and spunbonding processes. The microstructure is fine plastic fiber. In the case of high temperature shrinkage, the characteristics of plastic products, true high temperature plastics are not, high temperature resistance is a relative concept, so the non woven fabric in the micro fabric will produce a corresponding shrinkage reaction.

After high temperature sterilization, the fine plastic fibers of the non woven fabric(Disposable Non-woven Products Vendor) will shrink to some extent, which is reflected in the fact that the non woven fabric used after sterilization is more brittle than before sterilization, and the flexibility is lowered. The change in non woven packaging material is one of the reasons why the non woven fabric can only be used once.
