摘要： Conjugate filaments the components of which are comprised of the same constituents in dissimilar relative concentrations are produced by allowing the constituents of the molten stream of blended incompatible polymers partially to segregate in a forced flow conduit so that material removed from the outer periphery of the stream near the wall of the conduit will be of different relative concentration of constituents than material remaining near the center of the conduit and then removing separate streams of partially segregated material which are fed through suitable spinnerets to produce conjugate filaments. In another embodiment yarns the filaments of which are comprised of the same constituents in dissimilar relative concentrations are produced in the same manner.
