Abstract
The utility model belongs to the spinning apparatus technical field, in particular to a spinneret which is used for nine hollow fiber spinning. The spinneret resolves the technical problems that existing technical design is not reasonable, the rigidity and heat retention of produced fiber is not good and the like. The spinneret comprises a plate shaped body, a plurality of spinning channels penetrating in axial direction are distributed on the body. The spinneret is characterized in that one end of the spinning channel is provided with a feeding hole, the other end is the spinning structure, the spinning structure comprises nine spinning micro-holes which present T shape, each spinning micro-hole in the same spinning structure is arranged in radial shape by using the centre line of the spinning channel as the centre of a circle, an inner end of each spinning micro-hole is converged at the centre of the circle and is communicated with each other. Compared with the prior art, the spinneret used for nine hollow fiber spinning plate has the advantages: 1. the design is reasonable, the structure is simple, and the processing and manufacturing is easy; 2. the rigidity and heat retention of produced fiber is good and is not easy to deform.
Description
Technical field
The utility model belongs to spinning device tool technical field, especially relates to a kind of nine doughnut spinning spinneretss.
Background technology
The effect of spinnerets is with the high polymer molten of viscous state or solution, is transformed into the thread that the particular cross section shape is arranged by micropore, and process setting medium such as air or coagulating bath are solidified to form strand.The classification of pressing fiber is different with specification, and different specifications, shape, pass, material etc. are arranged.Spinnerets is worked under higher temperature and pressure, therefore requires to have withstand voltage, corrosion-resistant and enough mechanical strengths.
In order to produce the fiber of different structure, people have carried out long-term exploration, have proposed various solutions.For example in order to obtain the product of higher fiber characteristic, Chinese patent literature discloses a kind of molten spinning porous three-dimensional stereo crimped fiber spinnerets [application number: CN97242771.6], spinneret orifice on the spinnerets distributes in the form of a ring, spinneret orifice is made up of guide hole and spray silk pore, it is characterized in that: the cross sectional shape of described spray silk pore is to be formed around central array by a plurality of T type orifice rings, the cross-drilled hole in described each T shape hole is listed as circular side by side in the outside, cut off between the described adjacent cross-drilled hole end, T shape hole.
The somebody has invented a kind of spinning porous three-dimensional stereo crimped fiber spinnerets [application number: CN97242773.2], spinneret orifice on the spinnerets distributes in the form of a ring, spinneret orifice is made up of guide hole and spray silk pore, it is characterized in that: the cross sectional shape of described spray silk pore is that central authorities are C shape hole, outside C shape hole around being arranged with a plurality of T shapes hole, the cross-drilled hole in described each T shape hole is in the outside, and the vertical core in T shape hole is in the inboard and point to C shape hole.
Though such scheme has improved performance to a certain extent, still exist complex structure, processing cost height, technical problems such as the fibre structure complexity of being produced.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, simple in structure, is easy to processing and manufacturing, good, the on-deformable nine doughnut spinning spinneretss of fiber rigidity of being produced and warmth retention property.
For achieving the above object, the utility model has adopted following technical proposal: these nine doughnut spinning spinneretss, comprise tabular body, on body, be distributed with several spray silks that axially connect all, it is characterized in that, one end of described spray silk passage is a charging hole, the other end is spray silk structure, described spray silk structure comprises nine T-shaped spray silk micropores, each spray silk micropore in the same spray silk structure is that the center of circle is radial arrangement with spray silk channel centerline, and the inner of each spray silk micropore converges to above-mentioned circle centre position and is interconnected.
With in the spinnerets, described spray silk micropore evenly distributes in nine above-mentioned doughnut spinning.
With in the spinnerets, described body is in the form of annular discs, and has the installation through hole at the center of body in nine above-mentioned doughnut spinning.
Compared with prior art, these nine doughnut spinning are with the advantage of spinnerets: 1, reasonable in design, simple in structure, be easy to processing and manufacturing.2, fiber rigidity and the warmth retention property produced are good, not yielding.

Among the figure, body 1, through hole 10, a spray silk passage 2, charging hole 21, a spray silk structure 22, a spray silk micropore 220 are installed.
The specific embodiment
Shown in Fig. 1,2 and 3, these nine doughnut spinning comprise tabular body 1 with spinnerets, and body 1 is in the form of annular discs, and have the through hole 10 of installation at the center of body 1.Be distributed with the spray silk passage 2 that several axially connect on body 1, an end of spray silk passage 2 is a charging hole 21, and the other end is spray silk structure 22.
As shown in Figure 4, spray silk structure 22 comprises nine T-shaped spray silk micropores 220, each spray silk micropore 220 in the same spray silk structure 22 is that the center of circle is radial arrangement with spray silk passage 2 center lines, and the inner of each spray silk micropore 220 converges to above-mentioned circle centre position and is interconnected.Spray silk micropore 220 evenly distributes.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used morely, body 1, terms such as through hole 10, a spray silk passage 2, charging hole 21, a spray silk structure 22, spray silk micropore 220 are installed, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
