    摘要： Colored bicomponent filaments have a particulate colorant dispersed throughout one of the fiber domains while another of the fiber domains is colorant-free. More specifically, the filaments have at least two distinct components arranged longitudinally coextensive with one another. The arrangement of the components may be a sheath/core structure or a side-by-side structure. One of the components contains a colorant and the other one does not (i.e., is colorant free). The colorant-free component is most preferably formed of a polymeric material which is incompatible with the particulate colorant, whereas the colorant-containing component is most preferably formed of a polymeric material which is compatible with the particulate colorant.

    摘要： Bicomponent fibers of different cross-sections may be formed without changing the geometry of the spinneret orifices. More specifically, at least two polymers are co-melt-spun through an orifice of fixed geometry so as to achieve a bicomponent fiber having a desired cross-section. In order to change to a bicomponent fiber having a cross-section which is different, therefore, at least one of (1) the differential relative viscosity, (2) the relative proportions of the first and/or second polymers, and (3) the cross-sectional bicomponent distribution of the first and second polymers, is changed. In such a manner, therefore, a wide variety of bicomponent fibers having different cross-sectional geometries may be produced without changing the fixed geometry orifice through which the polymers are co-melt-spun. Thus, bicomponent fiber cross-sections may be "engineered" to suit a variety of needs without necessarily shutting down production equipment in order to change spinnerets. The bicomponent fibers are most preferably multilobal (e.g., trilobal) in which the core component is generally triangularly shaped.

    摘要： Synthetic polymers are melt-mixed and spun from a mixture of respective first and second polymer melt flows. Specifically, the mixture of first and second polymer melt flows are mixed at a fluidic mixing device having a mixing intersection which receives the first and second polymer melt flows and discharges the mixture thereof respectively into at least one or another of multiple discharge ports fluid-connected with a respective spinning nozzle. The mixed flow of first and second polymer melt flows is controlled by diverting the first polymer melt so that it (i) entirely flows along a first flow path to responsively merge with the second polymer melt flow at the mixing intersection of the mixing device and thereby cause the mixed polymer flow to be discharged through the one discharge port, or (ii) entirely flow along a second flow path to responsively merge with the second polymer melt at the mixing intersection of the mixing device and thereby cause the mixed polymer flow to be discharged through the other discharge port. The mixed polymer flow thereby diverted is thus spun by one or another of the spinning nozzles, respectively.

    摘要： Novel bicomponent fibers have a polyamide domain and a contaminant-containing polymer domain which is embedded entirely within, and thereby completely surrounded by, the polyamide domain. The preferred bicomponent fibers have a sheath-core structure wherein the polyamide domain constitutes the sheath and the contaminant-containing polymer constitutes the core. Surprisingly, even though the core is formed of a contaminant-containing polymer (which is difficultly spinnable), the bicomponent fibers are readily spinnable and exhibit properties which are comparable in many respects to fibers formed from 100% polyamide. Preferably, the fibers are concentric sheath-core bicomponent fibers having an uncontaminated nylon-6 sheath and a core formed from nylon-6 having a relatively high level of contamination in the form of the cyclic dimer of caprolactam and/or nylon-6 derived from colored regenerated post-consumer nylon carpet fibers.
