    摘要: An extrusion head (14) for producing yarn from a heat-plasticized material, including at least one body (16) defining a chamber (15) for distributing plasticized material over a plate (38) having extrusion openings formed therein. The chamber is supplied by an upper side channel (19) and comprises a downwardly decreasing cross-section of downward flow over at least a portion (24) of the vertical length of the chamber. This decrease is arranged to generate compressive and shear stresses over time in the plasticized material between the side supply channel (19) and the bottom of the chamber (27), said stresses being respectively substantially the same regardless of the path taken by said plasticized material.

    摘要: A melt spinning apparatus is disclosed which includes a supporting housing, a melt supply block mounted in the upper end of the housing, and a spin plate mounted adjacent the lower end of the housing so as to define a spinning chamber between the block and plate. A melt diverting plate is positioned in the spinning chamber for deflecting the melt entering into the chamber, and the melt diverting plate is configured such that substantially the same pressure drop occurs in the melt as it moves from the melt supply duct to all portions of the upper surface of the spin plate, so as to achieve a substantially uniform denier among the resulting filaments.

    摘要: A method for electroblowing fibers is provided which involves the steps of: forcing a polymer fluid through a spinneret in a first direction towards a collector located a first distance from the spinneret, while simultaneously blowing a gas through an orifice that is substantially concentrically arranged around the spinneret, wherein the gas is blown substantially in the first direction; wherein an electrostatic differential is generated between the spinneret and the collector; and collecting the fibers, and its use in preparing submicron scale fibers of various types, particularly hyaluronan fibers, and the hyaluronan nanofibers thus formed.

    摘要: A process for making a multi-ply fabric, which includes the steps of applying a water soluble material, which has no adverse effect on fabrics, around a water insoluble thread to provide a binding yarn; binding a plurality of unit fabrics one upon another with the binding yarn to provide a multi-ply fabric; putting the multi-ply fabric in water to dissolve the water soluble material thereby providing a multi-ply fabric bound with only the water insoluble thread.
