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 uniformly added to the polypropylene chip at an amount of 2%-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 with a spray amount of 0.6-1.1% of the weight of the nascent fiber, and then conduct a pre-network under the air pressure of 0.2-0.4 bar, and then perform drafting 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 chips is 0.02-0.03:1.
