Description of the Invention (>) Often, a tube or needle is used to achieve this purpose, so that a gaseous or liquid internal-pore fluid is ejected from the tube, thereby occupying the internal-pore space, and at the same time, the fiber The core is squeezed out of the orifice of the spinneret around the inner hole fluid. As the melt rotates, the nascent fibers can be solidified by cooling in a gaseous or liquid cooling fluid. For solution rotation, the nascent fiber can be solidified by evaporation of the solvent or by causing the polymer solution to condense by contacting the fiber with a solvent-concentrated liquid to form a fiber wall. A typical rotating component For example, a multi-component fiber described in British Patent No. 830,441 includes a front plate and a front plate spaced apart from each other, thereby providing a liquid channel therebetween. The front plate provides an extruded aperture therethrough, and at least one of the plates provides a plateau-like depression on the side of the plate facing the other plate to compress the liquid The channel is in an area surrounding the entrance of the extrusion orifice, so that the flow of the sheath-forming material converges substantially radially towards the entrance of the orifice. A tube is placed in the orifice inlet to supply the bore fluid. However, a continuing problem is how to uniformly supply the core and sheath forming material during the formation of the multicomponent fiber. Most spinnerets of this type are mostly made by hand one at a time. As a result, parts made for one spinneret may not always fit another spinneret. When the parts are not interchangeable 'any damage to one part of the spinneret assembly will render the entire assembly useless. When assembling or washing a conventional two-component or hollow fiber spinneret ', it is very easy to bend the fluid injection tube or needle slightly so that it is offset from the center of the rotary orifice. When this misfortune happens, ____4_____ This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page) -Line 丨 · 580526 5. Description of the Invention (h) The spinneret cannot be used until repaired. Another related problem of the traditional spinneret is related to the generation of concentricity between the inner hole and the fiber wall of the single-component hollow fiber and the additional core of the multi-component hollow fiber and the sheath. . Conventional spinnerets tend to form hollow fibers in which the inner holes / fiber walls and cores / claddings are not centered. The concentricity of the sheath and the core is important for obtaining a uniform fiber. The mantle and concentric conventions of the core are obtained by controlling the adjustment of the surface to regulate (control) the polymer flow. Such control surfaces are created by careful processing of both surfaces to produce a narrow opening that will effectively control the polymer when it is extruded at a uniform pressure and flow rate. U.S. Patent No. 3,458,615 discloses a method to maintain the concentricity of the mantle / core. To control the polymer mantle that will be extruded around the polymer mandrel, the polymer mandrel involves The formation of an annular wedge-shaped flow of the mantle polymer containing fluid flow around the axial direction. In order to maintain the concentricity of the fiber wall around the inner hole, other spinnerets have been provided with elements that centralize the tube and the inner hole of the spinneret. For example, U.S. Patent No. 4,493,629 describes a modular spinneret assembly that drills through the spinneret with most screws to gather the tube and the orifice of the spinneret in the center. These adjustment screws are not reliable, and when the spinneret is disassembled, washed, and then reassembled, the screws tend to move the tube out of the center for adjustment. Many devices have been proposed to ensure a uniform supply of the homogeneous sheath forming liquid to a perforated spinneret to achieve the goal of producing multiple hollow fibers with the same fineness, weight, and other characteristics as a concentric layer. This type of device usually involves these orifices and single or multiple spinnerets ------ s____ This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) One-(Please Read the precautions on the back before filling this page) 5J ·-丨 Line · 580526 A7 ______B7 __ 5. Description of the invention (々) Changes in the diameter or position of the board. The lack of concentricity and homogeneity remains the problem in making such single- or multi-component fibers. Another problem with existing spinnerets is the ability to transfer the polymer liquid or liquids evenly around a tube or needle located within the spinneret. U.S. Patent No. 5,320,512 discloses a spinneret having a plurality of separate material channels formed around the needle to transport the polymer liquid around the needle. When the polymer fluid flows through the main polymer fluid, the polymer liquids coming out of these individual channels must be pooled and melted together to form a single annular flow around the tube or needle. If a complete melt cannot be obtained, cracks will form below the fiber length at the interface where the respective fluids do not fully collect. Therefore, we need a spinneret design that will produce fibers that are concentric and uniform without the risk of cracks. Summary of the Invention The present invention provides an improved spinneret suitable for manufacturing hollow fiber that overcomes the conventional spinneret wire. The innovative spinneret assembly thus enables the continuous production of uniformly sized single and multi-component hollow fibers in which the fiber wall is concentric with the inner hole with a high degree of precision. Implemented in this way, these spinneret assemblies can additionally reduce defects in hollow fibers, extend the operating time of hollow fiber manufacturing, reduce spinneret maintenance time, and simplify spinneret assembly. The present invention is particularly suitable for producing high-quality multi-component fibers having one or more sheaths in an efficient manner.

In a basic form, the hollow fiber system has an open end, a cylindrical tube shape, and a uniform wall composition. This type of hollow fiber is sometimes referred to as a "single-component" fiber. The central pathway defining the hollow portion of the fiber is occasionally referred to as the "inner hole". "Multi-component" hollow fibers can also be made. The term "multi-component" means that the hollow fiber wall is formed by a mixed layer. The innermost layer, i.e., the one adjacent to the inner hole, is referred to herein as the "core" portion of the fiber. The outer layers of the core layer surrounding a multi-component fiber are referred to as "covered" portions. It has conventionally been used to refer to the "radiation" layer or portion of the membrane layer that is radially adjacent to the core layer. Successive outer film layers are labeled as the "second cover", "third cover" layer or portion, and so on. In order to maintain the inertia of the application term, the membrane wall portion of a single-component hollow fiber is still referred to herein as the core of the fiber, although the single-component fiber has no sheath portion.

Description of the invention (a) At the same time as the supply of the core forming material and the sheath forming material of 100, an inner hole forming fluid is injected into the inner hole forming a fluid inlet 1 i 3. A fluid channel is formed through the inner hole 112 and then into needle 13. The inner hole fluid emerges from the distal end of the needle 130 at a position located immediately downstream of the extrusion orifice 155 or at a position immediately downstream of the extension orifice 155. Because the core-forming material and the sheath-forming material are simultaneously and concentrically forming a fluid around the needle 130 and the inner hole exiting the needle through the lower annular channel 54 and from the extrusion orifice 155 It extends, so the formed extruder is a fiber, which includes an inner hole forming fluid in its center, the inner hole fluid is concentrically surrounded by a core forming material, and the core forming material is concentrically A cover-forming material is applied. As best shown in Figs. 1 and 2, the transverse channel 152 has a back-cut portion that completely surrounds the terminal portion of the needle 130 in a continuous manner and communicates with the upper annular channel 153. This structure eliminates the problem that the core-forming material is evenly distributed around the needles 130. At the same time, it also eliminates the problem of heading cracks caused by the incomplete mixing of the plurality of core material flows within the annular channel as disclosed in U.S. Patent No. 5,320,512 under the fiber wall. Meanwhile, when the spinneret assembly is removed from the rotating machine, since the core forming material passage 150 and the lateral passage 152 are already accessible, the spinneret management is relatively simple. This will facilitate arranging and reduce the reversal time of the spinneret. At the same time, the core-forming material channel 150 can be easily processed through the hole in the spinneret body 110, and at the same time, the lateral channel 152 can be easily and accurately processed by electrical discharge using a ring electrode (Also known as "EDM") technology to shape ______ 16 books or national standard (aNS) A4 specifications (21〇χ 297) ----------------- --- Order --------- line (please read the precautions on the back before filling this page) 580526 A7 --------- -B7 ____ 5. Description of the invention (). And 'Because the needle 130 is stably fixed in the loading hole 111 at the spinneret body, the needle's concentric alignment with the upper and lower annular channels 153 and 154 will be ensured, and therefore laborious And the tedious alignment procedure will be omitted, thereby reducing the reversal time even more. Compared to a conventional spinneret, the spinneret assembly 100 of this preferred embodiment has fewer parts and is easier to manufacture. Fig. 3 shows an alternative structure of the spinneret body of the first preferred embodiment which further simplifies the spinneret manufacturing process. In the first preferred embodiment illustrated in FIG. 2 'the core fluid passage 112 must be machined, such as drilled, with an angle and a high degree of accuracy without damaging the very small diameter Considering the integrity of the needle loading hole 111, the needle loading hole 111 meets the needle loading hole 111 and communicates with it. The spinneret body of Fig. 3 has an alternative design that eliminates this cumbersome processing step and thus reduces the cost of manufacturing a spinneret. In particular, a second inner hole forming fluid passage 114 is processed to be substantially parallel to the core forming material passage 150, and extends from the surface of the spinneret body 110 to the needle loading hole 111. The needle loading holes 111 are concentric. Since the second inner hole forming fluid passage 114 is coaxial with the needle loading hole 111, the processing procedure is greatly simplified. The inner hole forming fluid passage 112 'is processed in the spinneret body Π0 so that its direction is aligned with the inner hole forming fluid inlet 113 and forms a fluid passage 114 with the second inner hole at a position substantially from the needle loading hole 111. The removed points intersect laterally. The angled inner hole forming fluid passage 112 'has been processed so as to be associated with the second inner hole forming fluid passage 114 (the inner hole forming fluid passage 114 may be processed before machining the angled passage 112'), Because of the diameter of the needle loading hole 111 _______ 17 _____ This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page) _ · --- ----- Order! i — 580526 A7 B7____ 5. Description of the Invention (Λ) Compared with the angle, the diameter of the channel 112 'and the channel 114 are relatively large. The opening of the second inner hole forming fluid channel 114 at the surface of the spinneret body 110 can be plugged or sealed during or while the spinneret assembly 100 is being loaded in the rotating machine to avoid the inner Pore-forming fluid leaks. Other aspects of the alternative design of Figure 3 are similar to the design of Figure 2 above. According to the first embodiment of the present invention, the first preferred embodiment is shown in FIG. 4, which plots a method of increasing the number of fibers per spinneret by a factor of two. For the sake of clarity, the component numbers used in FIG. 4 are the corresponding component numbers in FIG. 1, FIG. 2 and FIG. 3 plus 100. FIG. 4 is a top view of the spinneret body 210. The significant difference between this specific embodiment and the specific embodiments drawn in Figures 1, 2 and 3 is that for each core forming material channel 250, two lateral channels 252a and 252b are formed, and each is connected with A back cut part is formed. Each of the lateral channels 252a and 252b is provided with an annular channel 253a and 253b (corresponding to the annular channel in FIGS. 2 and 3) and needles 230a and 230b (corresponding to the needle 130 in FIGS. 2 and 3). ). Similarly, other features drawn in the spinneret body 110 and the base plate 120 drawn in FIGS. 1, 2 and 3 are provided as corresponding features of the spinneret body 210 and the base plate 220. Thus, referring to FIGS. 3 and 4 'the lateral channels 252a and 252b extend from the core forming material channel 250 to the annular channels 253a and 2531 surrounding each of the needles 230a and 230b of the corresponding extrusion orifice) At the edge.
