The characteristic of the water-repellent and anti-fouling polypropylene BCF yarn is that the nano-level anti-fouling, dust-proof, anti-static masterbatch is evenly added to the polypropylene chip at an addition amount of 2% to 3%, and the screw is melted and sprayed. After cooling, spray the mixed solution of silicone oil preparation and spinning oil on the surface of the nascent fiber, the spraying amount is 0.6-1.1% of the weight of the nascent fiber, and then pre-network under the air pressure of 0.2-0.4 bar, and then draw and BCF Puffing deformation, cooling and setting, output, entangled network and winding to prepare polypropylene BCF yarn.

According to the above-mentioned production method of water-repellent and anti-fouling polypropylene BCF yarn, the key is that the mass ratio of the nano-level anti-fouling, dust-proof, anti-static masterbatch and polypropylene chip is 0.02-0.03:1.
