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： Novel bicomponent fibers have a sheath domain and an core domain which is embedded entirely within, and thereby completely surrounded by, the polyamide domain. The core domain is annular and defines a longitudinally extending central void. The preferred bicomponent fibers have a sheath-core structure wherein the polyamide domain constitutes the sheath and a fiber-forming polyolefin polymer constitutes the core. The preferred trilobal bicomponent fibers will exhibit a modification ratio of between 2 to 4, an arm angle of between 7.degree. to about 35.degree., and a total cross-sectional void area between about 3 and about 10 percent. Each lobe of the fiber may optionally contain a lobal void space which, if present, is preferably radially elongate in cross-section.

摘要： Synthetic filaments include a nonaqueous additive system having dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier. The additive system is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of polymeric material, melt-spun filaments having different additive attributes may be produced on a continuous basis (i.e., without shutting down the spinning operation). The filaments may be included in yarns which are formed into carpet structures.

摘要： Spinnerette assemblies for forming synthetic fibers whereby a relatively thin orifice plate is compressively sealed against a planar face of a mounting block. The spinnerette assemblies preferably include a mounting block having a planar mounting face and a least one supply bore having a discharge opening at the mounting face. A planar orifice plate is positioned in contact with the mounting face of the mounting block and includes a capillary opening in fluid communication with the discharge opening of the supply bore. A series of attachments (preferably screws) circumferentially surround the capillary opening of the orifice plate so as to compressively rigidly fix the orifice plate to the mounting face of the mounting block and thereby seal the capillary opening against fluid leakage. Most preferably, the attachments (e.g., screws) are substantially equally circumferentially spaced apart from one another in surrounding relationship to the capillary opening so as to impart a symmetrical circumferential compressive sealing force therearound.

摘要： A method of separating two immiscible, melt-viscosity-differing thermoplastic polymer components from a mixed liquid stream thereof forms two discrete and continuous phases having a sheath/core configuration, wherein the sheath substantially contains the polymer component with the higher melt viscosity and the core substantially contains the polymer component with the lower melt viscosity. The mixed liquid stream contains a predominant amount (i.e., greater than 50% by volume) of the higher viscosity polymer component and a minority amount (i.e., less than 50% by volume) of the lower viscosity polymer component. The method involves directing the stream through a shear zone at a shear temperature and a shear rate sufficient to form the two discrete and continuous phases, the first of which substantially contains the lower viscosity polymer component and the second of which substantially contains the higher viscosity polymer component.

摘要： Relatively thin (e.g., thickness of less than about 2.5 mm, and typically no greater than about 1.0 mm) plates for synthetic fiber-forming spin packs include a first metal layer exhibiting a relatively slow photochemical etching property and a second metal layer exhibiting a relatively fast photochemical etching property which are adhered (laminated) to one another to form a composite substrate structure. The differential etch rates as between the first and second metal layers permit relatively dimensionally larger distribution channels and relatively dimensionally precise through holes to be formed in the composite substrate. In this regard, the second metal layer permits the formation via photochemical etching of dimensionally deeper and/or wider polymer distribution channels. The first metal layer, on the other hand, allows for the formation of relatively dimensionally precise through holes via concurrent (simultaneous) etching with the second metal layer.
