The invention discloses a hydrophobic flame-retardant nonwoven fabric and a preparation method thereof. The present invention uses guaiacol to treat the surface of the non-woven fabric, chelates metal ions, and increases the roughness of the fabric; and then, under the photocatalysis, the double bond in the molecular structure of the guaiacol and the sulfhydryl group are chemically reacted to combine, thereby The technical purpose of reducing the surface energy of the fabric surface and improving the hydrophobicity of the non-woven fabric is achieved. Compared with the prior art, the hydrophobic flame-retardant non-woven fabric prepared by the present invention also has the characteristics of biodegradation, and enhances the antibacterial, anti-ultraviolet, flame-retardant and durable characteristics of the polylactic acid non-woven fabric. |
