Method for producing water-repellent and anti-fouling polypropylene BCF filament

The invention relates to the technical field of textiles, and discloses a method for producing a water-repellent and anti-fouling polypropylene BCF filament. The method comprises the following steps of S1, stirring a silicone oil preparation and a spinning oil agent in a stirrer at a low speed for 1.5 hours, so that the silicone oil preparation is thoroughly mixed with the spinning oil agent to prepare a compounding solution; S2, adding a polypropylene slice to the inside of a first dryer for drying, and adding the polypropylene slice dried by the first dryer to the inside of a main extrusionmachine for melting to obtain a first melt; S3, adding an anti-fouling dustproof and antistatic functional masterbatch to the inside of the second dryer for drying, and adding the anti-fouling dustproof and antistatic functional masterbatch after drying through the second dryer to the inside of an additional extruder for melting. The method for producing the water-repellent and anti-fouling polypropylene BCF filament can
