METHOD FOR FORMING EXTREMELY FINE STRUCTURAL FIBER WITH REGULARITY

摘要

PROBLEM TO BE SOLVED: To provide a method for forming a multiple aggregates having a uniform extremely fine regularly arranged structure and group of aggregates having the same form or different forms in long axial or longitudinal direction in a conjugated fiber obtained by using at least ≥2 kinds of polymeric materials having different physical properties such as refractive index, strength, elasticity, etc.;SOLUTION: This extremely fine regularly arranged structural fiber in which the dimension of the extremely fine structural body and a pitch distance of the extremely fine structural body are also regulated, is formed by supplying one of the components of ≥2 kinds of molten polymeric materials having different physical properties through penetrated holes communicating with the multiple openings separated as a definite arrangement, also supplying other component through a passage installed between the penetrated holes and also a flowing speed and flowing direction-regulating relaxing groove installed in the surroundings communicating with the passage exit, joining the flows in a state of maintaining a definite arrangement structure, then compressing and making as thin at a funnel-formed passage following in lower direction and covering its outer peripheral part with any of a component and then compressing again, or using a spinneret repeating the above processes as multiple steps to increase compression ratio.;COPYRIGHT: (C)2007,JPO&INPIT
