Technical Field

The invention relates to the technical field of sterilized fabrics, in particular to a sterilized fabric.

Background

The nano-silicon nitride powder is proved by a plurality of research organizations to have broad-spectrum virus and bacteria killing function. Recent studies have shown that it also has a rather strong killing function against coronaviruses. As a material for artificial joints, it has again proved to be harmless to the human body. Many companies at home and abroad try to use materials such as copper oxide, nano silver and the like as filling materials to produce products such as masks, protective clothing and the like, but the toxicity and the safety of the materials are not verified. The invention uses silicon nitride powder of Sintx in the United states to be uniformly fixed in the weaving cloth. Several companies in the united states have attempted to use the company's powder for fabric inside, such as compressed air spraying, plastic particle mixing, pelletizing, spray-melt molding, and surface coating.

However, none of these methods achieve uniform powder distribution, resulting in 1) powder packing and 2) failure to bind to the woven fabric fibers. 3) The glue or other materials completely wrap the powder, so that the silicon nitride particles lose activity.

In response to this reality, the present invention provides a sterilized fabric.
