Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to an antibacterial and deodorizing hot air non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. The non-woven fabric has no warp and weft threads, so it is very convenient to cut and sew, and it is light and easy to shape. Because it is a fabric that does not require spinning or weaving, it just orients or randomly arranges textile staple fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical methods to reinforce it. [0003] Non-woven fabric is a kind of non-woven fabric, which directly uses high polymer chips, short fibers or filaments to form fibers through air flow or machinery, and then is reinforced by hydroentanglement, needle punc...
