Abstract
A binary conjugated filament comprising one polymer component (A) and a polymer component (B) which is more soluble than polymer (A), the cross-sectional configuration of the filament being such that the polymer component (A) is divided into not less than five segments by the polymer component (B) and one of these segments is disposed in the center of the other segments, the areal center of the central segment residing on the line (r) in the range of: R/300.ltoreq.r.ltoreq.R/2 wherein R is the radius of the circular cross-section of the conjugated filament and r is the length from the areal center of the cross-section of the conjugated filament to the areal center of the segment disposed in the center of the other segments. The filament may be made into a woven or knitted fabric which is treated to remove the more soluble polymer component (B) to provide a fabric product exhibiting good handle characteristics.
