Description

technical field

[0001] The invention relates to the technical field of sponges, in particular to a sponge with anti-mite, anti-mildew and antibacterial functions, and at the same time, the invention also relates to a preparation method of a sponge with anti-mite, anti-mildew and anti-bacterial functions. Background technique

[0002] Sponge is a common daily necessities in people's life. However, traditional sponges are easy to mold, breed bacteria and mites, cause harm to the human body, and cause various diseases. The existing sponges generally do not have effective anti-mite, anti-mildew, and antibacterial effects.

[0003] Therefore, we propose a sponge with anti-mite, anti-mildew and antibacterial functions and a preparation method thereof. Contents of the invention

[0004] The object of the present invention is to provide a kind of sponge with anti-mite, anti-mildew and anti-bacterial functions and its preparation method, to solve the problems raised in the above-me...
