A technique for spinning composite ultra-fine polypropylene filament features use of ordinary or blend modified PP resin (51-90 Wt.%) and fibre-forming high polymer (10-49 Wt.%) as raw materials, andpeeling-type compound spinneret pack. Both components are separately molten and then flow into the compound spinneret pack, where their mixture is exttruded out. Through cooling to shape and drawing,composite ultra-fine polypropylene filament is obtained with 0.1-1.0 dtex of single-fibre size, 2.6-3.0 CN/dtex of strength and 20-40% of stretch. Said filament can be dyed by disperse dye.
