This invention is about a kind of producing method of self-curling long filament with superthin structure, with the method of three groups fusing composite spinning. The fibers of the 3 groups are the long fibers with the titer of single fiber 1-6 dtex and the number of pores (12-72)*2. The fibers have at least 7% curling and shrinking percentage after hotly forming and at least 20% curling and shrinking percentage after alkali process. The cross-section of one single fiber is paralleling or eccentric skin-core structural circle, ellipse or snowman. One side of the cross section has fortuitous laminated structure, and the outside fiber ratio is 0.3-0.8 dtex. The producing steps of the self curling long fibers are slice choosing - slice drying - slice fusing - combined spinning - forming curling - drafting to form the shape. By mixing the spinning units and combining the units of big heat shrinking percentage in the paralleling or eccentric skin-core structural way, we can solute the soluble units during the after operation, and separate the outboard fibers of the self curling filaments, making the fibers more slender and modulus smaller. In a word, the curling and shrinking ratio, feeling and amenity have been largely improved.
