Water-repellent and lipophilic composite needle-punched nonwoven fabric and preparation method thereof

The invention relates to a water-repellent and lipophilic composite needle-punched nonwoven fabric and a preparation method thereof. The method comprises the following steps: blending a PET fiber and a polyolefin-based fiber in a mass ratio of 3:1-1:3, and performing needle punching to obtain a composite needle-punched nonwoven fabric; carrying out hot-drying treatment on the composite needle-punched nonwoven fabric at 110-160° C. for 40-90 min; and carrying out water-repellent finishing on the hot-dried fabric using 50-70 mL/L of an aqueous solution of a modified resin-based fluorine-free waterproofing agent, and drying to obtain the water-repellent and lipophilic composite needle-punched nonwoven fabric, wherein the water-repellent finishing is dip rolling, the air pressure is 1.8 kPa and the liquid carrying rate is 160-230%. The preparation method of the invention is simple, and the prepared composite needle-punched nonwoven fabric has significantly improved water repellency, lipophilicity and tensile strength compared with the fabric before treatment.
