摘要： A nozzle is described for downwardly directing air from an air intake of a fiber draw unit into a longitudinal channel of the fiber draw unit for forming spunbond polymeric fibers. The nozzle includes an upper eductor connected to the fiber draw unit and a lower eductor adjustably connected to the fiber draw unit and below the upper eductor. The nozzle includes a nozzle cavity that narrows from a nozzle inlet to a nozzle outlet and includes a downward turn of 90 degrees or less. Air directed through the nozzle outlet flows in a direction parallel to a wall of the longitudinal channel.

摘要： A melt spinning apparatus including a spinpack with a die tip block having a recess with a converging portion, such as an angled trough, which terminates in a row of filament discharge outlets. The recess selectively receives a configuration insert, such as a side-by-side insert or a sheath-core insert, that separates the converging portion of the recess into two sheets of liquid that combine at the filament discharge outlets. The spinpack may be configured by inserting either of the inserts to produce filaments having different cross sectional configurations of two different materials. Separation of the two liquids prevents premature interaction between the two liquid flows which minimizes instabilities between the liquid flow interface. The minimization of these instabilities can result in less formation of shot and improve other significant finished product properties. In addition, each type of liquid material may be maintained at an optimum temperature for proper extrusion.

摘要： Disclosed are polyester multi-filamentary yarn useful as a reinforcement for tires and a dipped cord formed therefrom. The polyester multi-filamentary yarn comprises at least 90 mol % of polyethylene terephthalate and has an intrinsic viscosity of 0.70-1.2 and a tenacity of 5.5-8.5 g/d with an intermediate elongation difference (E1nullE0) between intermediate elongations E0 and E1 amounting to 6% or greater. The polyester dipped cord is produced by subjecting at least two strands of polyester multi-filamentary yarn to first twisting and second twisting, the polyester multi-filamentary yarn comprising 90 mol % of polyethylene terephthalate; forming the strands into a fabric; and treating the fabric with blocked isocyanate and resorcinol formaldehyde latex (RFL), wherein the cord satisfies the following characteristics: a) a tenacity of 5.0 g/d or greater, b) a dimensional stability index (E4.5nullSR) of less than 7.0%, c) a breaking elongation of 9% or greater, and d) an intermediate elongation difference (E1nullE0) of 3% or less. Showing a harmony of high elastic modulus and low shrinkage, the filamentary yarn and dipped cords are superior in dimensional stability and fatigue resistance, so they can be used as reinforcements for rubber composites such as tires

摘要： Melt blown nonwoven webs are formed by supplying fiber-forming material to a planetary gear metering pump having a plurality of outlets, flowing fiber-forming material from the pump outlets through a plurality of inlets in one or more die cavities, and meltblowing the fiber-forming material. Each die cavity inlet receives a fiber-forming material stream having a similar thermal history. The physical or chemical properties of the nonwoven web fibers such as their average molecular weight and polydispersity can be made more uniform. Wide nonwoven webs can be formed by arranging a plurality of such die cavities in a side-by-side relationship. Thicker or multilayered nonwoven webs can be formed by arranging a plurality of such die cavities atop one another.

摘要： A unique isotropic sub-denier spunbond nonwoven product created by an apparatus and method comprising a unique multi-head resin metering system, a spinneret head with spinning sections, separated by a quench fluid extraction zone, a two sided, multilevel quench system, a fluid volume control infuser system which automatically guides the filaments into the filament drawing system while conserving energy by using a portion of the quench fluid as part of the drawing fluid and also minimizing turbulence at the entrance to the draw slot. The filament drawing system comprises a draw jet assembly with adjustable primary and secondary jet-nozzles and a variable width draw jet-slot. The entire draw jet assembly is moveable vertically for filament optimization. The offset, constant flow secondary jet-nozzle system provides an unexpectedly high velocity increment to the filaments by oscillating the filaments and increasing their drag resulting in remarkably low fiber denier on the order of 0.5 to 1.2. The apparatus also embodies a draw jet extension with an adjustable slot and contains two in-line or tandem which are also adjustable and maintain fiber tension and draw force through the lower end of the draw system. Drawn filaments are decelerated in an adjustable fluid volume control diffuser system which controls the amount and pressure of fluid in the diffuser and controls turbulence. The filaments enter into the fluid control system and begin to describe a downward spiraling motion results in remarkably uniform isotropic web where the machine to cross direction ratios of the bonded web physical properties such as tensile strength and elongation approach a ratio of 1:1.

摘要： A method of producing a multifilament yarn from a thermoplastic polymer includes the steps of producing a majority of fluid filaments by melt-extrusion, cooling the fluid filaments to at least partly harden at a point of consolidation, guiding the hardened filaments by a yarn guiding element, sensing the tension of the hardened filaments, varying the distance between the yarn guiding element and the point of consolidation by moving the yarn guiding element in a vertical direction in response to the sensed tension, and combining the majority of hardened filaments to form at least one multifilament yarn. An apparatus for producing a multifilament yarn from a thermoplastic polymer includes a yarn guiding element being movable in a vertical direction. A drive serves to change the vertical position of the yarn guiding element with respect to a point of consolidation of the filaments. At least one sensor senses the yarn tension of the filaments. A control unit serves to control the drive in response to the sensed yarn tension to change the vertical position of the yarn guiding element.
