Technical Field

The invention relates to an antibacterial material, in particular to a preparation method of a novel flame-retardant non-woven fabric.

Background

The flame-retardant non-woven fabric can be divided into flame-retardant needle cotton and flame-retardant hot air cotton according to the process.
