Trim part for a vehicle, comprising at least a fibrous layer comprising of thermoplastic bicomponent filaments or staple fibers, consisting of a first polymer forming the sheath of the bicomponent filament or staple fiber and a second polymer forming the core of the bicomponent filament or staple fiber and whereby the fibrous layer is consolidated by heating thereby melting the sheath polymer forming binding points between the filaments or staple fibers, characterized in that at least the sheath of the bicomponent filament or staple fiber comprises a shrinkage reducing additive being at least a polysiloxane, preferably a polydimethylsiloxane.

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.
