NOVELTY - The preparation method of the cotton and linen textile fabric with strong hydrophobicity involves: preparing ethanol solutions from diamine and dicarboxylic acid respectively, adding amino graphene, stirring and mixing at 60-80 ℃ for reaction for 30-60 minutes to obtain amino graphene modified polyamide, and spinning the amino graphene modified polyamide into polyamide fibers; soaking the cotton and linen textile fabric in water for 7-10 hours, taking out and then carrying out steam treatment for 31-35 minutes; adding 6-10 g carboxymethyl chitosan into 160-200 mL of deionized water, stirring for dissolving, then adding 0.6-0.8 g sodium periodate, heating to 55-58 ℃, and stirring for reacting for 1.5-2 hours to obtain a reaction solution. USE - Preparation method of the cotton and linen textile fabric with strong hydrophobicity. ADVANTAGE - The hydrophobic property is enhanced through the nano titanium dioxide. The methyl trifluoro propyl silicone oil forms a layer of elastic soft compact organic silicon molecular film on the surface of the fiber. The hydrophobic property is further enhanced, and then the elastic soft compact organic silicon molecular film is matched with the surface layer of the polyamide fiber for use, so that the effects of super-strong hydrophobicity and good wearing comfort are achieved.
