Problems solved by technology

The raw material of gauze cloth is natural and environmentally friendly, with good water absorption and oil absorption. The disadvantage is that it is easy to hide dirt and mold if it is not dried in time. Microfiber cloth is made of chemical fiber and has poor water absorption, but because it is made of chemical fiber , not very suitable for washing dishes, mostly used for other cleaning purposes
In addition, the antimicrobial properties of the aforementioned gauze wipes as well as the microfiber wipes were insufficient
Although some cleaning products such as rags have been treated with antibacterial agents to achieve antibacterial effects, most of the antibacterial agents used are chemical synthetic agents, and consumers still have concerns about the environmental protection of the products during use
