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： Continuous anionic polymerization and melt-spinning of a polycaprolactam includes forming a reaction mixture by bringing at least two streams of liquid caprolactam respectively containing a polymerization initiator and co-initiator into contact with one another, and then subjecting the reaction mixture to anionic polymerization reaction conditions in the reactor zone to obtain a molten polycaprolactam. The molten polycaprolactam is the directly (i.e., without intermediate solidification) transferred to, and extruded through, a fiber-forming orifice of a spinneret to form a fiber thereof. A spinneret zone downstream of the reactor zone thus receives the molten polycaprolactam directly from the reactor zone and forms a fiber therefrom by extruding it through the spinneret's fiber-spinning orifice.

One exemplary system to achieve such continuous anionic polymerization and melt-spinning of polycaprolactam includes a mixer for receiving and mixing at least two streams of liquid caprolactam respectively containing a polymerization initiator and co-initiator, and a reactor and melt-spinning apparatus downstream of the mixer. The reactor and melt-spinning apparatus most preferably is formed of multiple plates which establish a reactor zone having a flow path for the reaction mixture which is sized and configured to achieve a predetermined residence time of the reaction mixture therein, and a temperature control zone in thermal communication with the reactor plate for controlling the temperature of the reaction plate to achieve anionic polymerization reaction conditions while the reaction mixture is flowing along the defined flow path therein to obtain the molten polycaprolactam. A spinneret zone downstream of the reactor zone thus receives the molten polycaprolactam directly and forms a fiber therefrom by extruding it through the spinneret's fiber-spinning orifice.

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.
