A nozzle device is disclosed for producing floral leaf shaped multifilament which is good in opacity and color development. The floral leaf shaped multifilament has a cross section looking as the 6-8 thermoplastic opaque polymer layers containing 5-30% weight of white pigment selected from titanium oxide, zinc oxide, aluminium oxide, zirconium oxide, or magnesium oxide are disposed as a floral leaf in the thermoplastic transparent polymer layer containing 0-1.5% weight of white pigment. And each polymer layer is selected from nylon-6, nylon-66, polyethylene terephthalate, or polybutylene terephthalate.
