The invention provides a production method of double-component spun-bonded non-woven fabrics. Double-component PP/PE filaments are adopted and are processed through slicing, filtration, hot air drying, heating and melting, positive pressure stretching, slitting and package and other processes, fiber filaments are externally loose and curled and are internally tightened and straight after deformation and have fluffy and stereochemical structures. Compared with common filaments, the original high strength, abrasion resistance and other excellent properties of fibers are kept, the structures and morphology similar to silk fiber flocculi are obtained, especially the filaments have excellent elasticity, few hairiness, good anti-pilling properties and high in firmness, web forming is uniform, gram weight can be up to 9 G, the width can be up to 3.2 M, and the pulling strength is longitudinally greater than 18 N and is transversely greater than 9 N.
