Abstract

PURPOSE: The island component is formed into specifically arranged groups of fine continuous lines and a plurality of these groups are positioned in the flow of the sea component to form conjugate fibers with perfect island-in-sea section continuously with no problems on quality such as viscosity difference.
CONSTITUTION: The fine continuous lines of the island component 8 are arranged in a plurality of annular circles or additionally another continuous line of the island component is passed through the center of the annular circles. When each annular circle is named as a, b, c, d... in order from the innermost one and each interval between these circles is expressed with L1, L2, L3... in order, the interval between the groups of island continuous lines is set so as to satisfy the equation: L1>L2>L3 or L1>L2≈L3 or L1≈L2>L3.L1 is required to be 1.1W3 times Ln (the interval in the outermost circle).
