The present invention generally relates to the design and manufacture of nanofiber layers, webs, films, or membranes that may be self-supporting and can function as standalone products. More particularly, the present invention relates to a microporous nanofiber films and the use of such films in a wide variety of products and applications, including applications where physical property tuning is typically limited. Generally, the microporous films of the present invention can function as a standalone nanofiber membrane or can be bonded to other microporous films to produce a layered stacked film stack with customizable properties. Unlike conventional microporous films available in today's market, the microporous films of the present invention can be lighter, require less raw material cost to produce, and can improve operating performances in a variety of applications.

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.
