Abstract
The utility model discloses a spinneret plate, in particular to a spinneret plate used for producing Lyocell fiber. The spinneret plate is a rectangular, on which 2000 through 20000 spinneret holes are distributed; the hole cores of all the spinneret holes are arrayed on the same holes array. The column of the holes array presents an angle ranging from 0 to 45 degrees with the corresponding spinneret plate, or the row of the holes array presents an angle ranging from 0 to 45 degrees with the vertical line of the spinneret plate. The spinneret plate of the utility model is provided with more spinneret holes compared with the original spinneret plate, in this way, the efficiency of the spinneret plate in dealing with the fiber yarn is raised. As the column or the row of the holes array formed by the spinneret holes arranged on the spinneret plate of the utility model is not completely arrayed on the horizontal line of the spinneret plate or a direction parallel to the vertical line of the spinneret plate, the spinning ejected from the spinneret plate does not tend to conglutinate, therefore, the fiber yarn finally obtained has uniform thickness and good quality.
Description
Technical field
The utility model relates to the spinnerets that a kind of spinning is used, and particularly a kind ofly is used to produce the spinnerets that the Lyocell fiber is used.
Background technology
Spinnerets is as the indispensable precise part of spinning machine, and its function is that the spinning melt of Spinning pumps (or claiming measuring pump) accurate measurement is extruded the fibre bundle that has certain thickness and be of close texture by the spray of the micropore on the spinnerets.Its shape and characteristic size are the essential condition that guarantees the fibrous finished product quality.
The fiber that the utility model relates to is called as the Lyocell fiber, just with cellulose dissolution in a kind of organic solvent, and this solution extruded a fibrid cellulose fiber of being produced from spinnerets.
The production method of present this fiber is at first cellulose to be mixed in the solvent, cellulose is extruded the continuous thread of formation through spinnerets under the state of heat, these continuous threads are also entered in the coagulating bath subsequently by the air cooling, so that make liquid cellulose be solidified the formation continuous tow.Yet; facts have proved; in existing production process; owing to there are a plurality of little orifice plates to constitute on the existing spinnerets; many spinneret orifices that run through on each orifice plate, have been comprised; the treating capacity of this spinnerets is smaller, and because fiber inhomogeneous cooling in cooling procedure is even, usually can cause the uneven situation of producing of fiber.
In order to change this situation, application number is that 94190547.0 patent of invention discloses a kind of spinnerets, it has one and is arranged to rotational symmetry structure basically, the spinnerets body that the admission passage that refrigerating gas uses is arranged in the central, the admission passage that cellulose solution is used, a noble metal system, the plug-in type that processes through the deep drawn spray silk part of annular, the spinneret orifice that mutual spaced set is arranged on this spray silk part, look up from the footpath, these spinneret orifices are crisscross arranged, this can make the temperature that keeps special uniformity in the spinning process, the thread that spinnerets is extruded obtains cooling uniformly, the cross section of spray silk part is ware shape (ship shape) structure, this spinnerets also has a deflection plate, in order to the refrigerating gas baffling is passed the thread of extruding from spinneret orifice, this utility model is owing to the mode that has adopted to the fiber blow gas, so influenced the quality of tow, extensibility and percentage elongation, can spin out the fiber of performance unanimity, yet in this invention, because the area of the spinnerets that is utilized is limited, so the fiber efficient of producing is relatively low.
On Donghua University's journal in April, 2003, delivered and be entitled as " spinning technique is to the influence of high molecular weight Lyocell cellulose fibre performance " literary composition, mentioned the spinnerets hole count in the literary composition to the fibre machinery Effect on Performance, wherein mentioning the spinneret hole number is sharply to descend with the increase of hole count to the fibre machinery Effect on Performance, the spinnerets hole count is many more, the flow path and the internal stress of spinning solution in each hole of flowing through has nothing in common with each other, the architectural difference of each monofilament in the fibre bundle that obtains is just big more, and this all can cause the decline of fibrous mechanical property.
In view of this spy provides the utility model.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and the spinnerets that provides a kind of spinning to use particularly a kind ofly is used to produce the spinnerets that the Lyocell fiber is used.
For solving the problems of the technologies described above, the utility model adopts the basic design of technical scheme to be: a kind of spinnerets, wherein: spinnerets is a whole rectangle spinnerets, 2000～20000 spinneret orifices are distributing on it, the hole heart of spinneret orifice is arranged on the hole battle array, the horizontal edge of its corresponding spinnerets of row of Kong Zhen is 0～45 °, and/or the longitudinal edge of the row of Kong Zhen and spinnerets is 0～45 °.
The spinneret orifice that the spinneret orifice of described spinnerets is a size, shape is consistent.
The diameter of the spinneret orifice of described spinnerets is 0.05～0.5mm.
The utility model provides a kind of spinnerets again, the spinneret orifice of wherein distributing on the spinnerets 6000～15000 sizes, shape unanimity, and the diameter of spinneret orifice is 0.05～0.5mm.
The diameter of the spinneret orifice of described spinnerets is preferably 0.07～0.15mm.
The spinneret orifice length of spinnerets described in the utility model and the ratio of diameter are 1～10.
The ratio of described spinneret orifice length and diameter is preferably 2～5, and the length of the spinneret orifice described in the utility model is meant the distance of the spinneret orifice that dynamic analysis of spinning is flowed through.
This kind spinnerets that the utility model is designed has with respect to more spinneret orifice on the spinnerets in the past, can improve the efficient that spinnerets is handled fibre bundle like this.And come out to from spinnerets this segment distance of coagulating bath at dynamic analysis of spinning in the past, the dynamic analysis of spinning of every bundle is bonded together easily mutually, thereby causes final spun tow fineness degree heterogeneity, has influenced the quality of final fibre bundle.Because the row of all formed Kong Zhen of spinneret orifice or row are not arranged in the direction that parallels with the horizontal edge or the longitudinal edge of spinnerets fully on the spinnerets in the utility model, so it is bonding mutually that the dynamic analysis of spinning that sprays from spinnerets of the present utility model is difficult for, the tow thickness homogeneous that finally obtains has good quality.
In addition, even adopting cooling air again in section air gap of this from the spinnerets to the coagulating bath dries to tow, to reach the purpose of solidifying of accelerating tow, because the row of the formed Kong Zhen of spinneret hole in the utility model or row are not arranged in the direction that parallels with the horizontal edge or the longitudinal edge of spinnerets fully, even so adopt the processing mode that blows cooling air, dynamic analysis of spinning in the utility model is not still to be bonded together mutually, the fineness of the tow that finally obtains still has homogeneous, stable advantage.
Therefore adopt spinnerets of the present utility model, not only improved the working (machining) efficiency of spinnerets processing weaving melt, for the quality that improves tow, all once also improved a lot simultaneously.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
