Abstract
The utility model discloses a spinneret plate adopting triangular micro holes and hollow structures. The spinneret plate comprises a round spinneret plate body, wherein a plurality of spinneret holes are formed in the spinneret plate body. The spinneret plate is characterized in that three micro holes are arranged in each spinneret hole, and the connecting lines of the centers of the three micro holes form a large triangle. According to the utility model, the spinneret plate adopts the design that every three corresponding micro holes with the same circular or triangular cross sections form one large triangular spinneret hole; the cross sections of the large triangles have the characteristic of high light-reflection performance; the hollow structure surrounded by every three corresponding micro holes ensures that the mass of a foreign fiber per unit length is reduced and the foreign fiber has very high heat-preservation performance.
Description
Technical field
The utility model belongs to synthetic fiber spinning field, relates in particular to a kind of triangle hollow type spinnerets.
Background technology
Spinnerets claims again spinning cap, and spinnerets can be transformed into the thread that has particular cross section shape by the high polymer molten of viscous state or solution by spinneret orifice, and process setting medium is as air or the curing strand that forms afterwards of coagulating bath.The shape of cross section that spinneret orifice cross sectional shape on spinnerets is changed over to some special shapes and can change the chemical fibre silk thread gushing out, is profiled filament, and profiled filament has the features such as special gloss, bulkiness, anti-pilling, resilience, hygroscopicity.Conventionally the shape of cross section of profiled filament can not be equal to the cross sectional shape of spinneret orifice, and silk thread can after disengaging spinneret orifice, a certain amount of deformation occur.Also do not have one to there is reflective characteristic at present good, the foreign fiber of light weight.
Summary of the invention
In order to overcome this problem, the utility model provides a kind of triangle hollow type spinnerets being made up of three internal structures.
The technical solution of the utility model is to provide a kind of triangle hollow type spinnerets, comprise: circular jetting filament plate body, described spinnerets body is provided with some spinneret orifices, it is characterized in that, in each described spinneret orifice, be provided with three micropores, a large triangle of above-mentioned three described micropore line of centres compositions.
Preferably, three described micropores are that equilateral triangle of the same size interval arrange, and three described micropores surround part for a described spinnerets body part.
Preferably, three described micropores are that circle of the same size interval arrange, and three described micropores surround part for a described spinnerets body part.
Preferably, described spinneret orifice is truncated cone shape, and above-mentioned three described micropores are positioned at compare little one end, described spinneret orifice truncated cone shape cross section, and described micropore is also truncated cone shape, and described micropore truncated cone shape major part is consistent with microcephaly's direction and described spinneret orifice truncated cone shape.
Preferably, described spinneret orifice is arranged on spinnerets body taking the spinnerets center of circle as datum mark is centrosymmetric, and described spinneret orifice is through described spinnerets body, and described micropore is communicated with described spinneret orifice.
Triangle hollow type spinneret design of the present utility model becomes three identical circular cross-sections or a large triangle spinneret orifice of three common compositions of triangular-section micropore, large leg-of-mutton cross section has the advantages that reflective function is good, and the hollow structure that three micropores surround place reduces the quality of this foreign fiber unit length and has good thermal property.

In figure: 1. spinnerets body, 2. spinneret orifice, 3. triangle micropore, 4. circular micropore.
Detailed description of the invention
Below detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, a kind of triangle hollow type spinnerets of the present utility model, spinnerets body 1 is circular, taking its center of circle as the center of circle, spinneret orifice 2 forms three concentric circles and is evenly arranged on spinnerets body 1, is provided with three micropores of the same size in each spinneret orifice 2, the line of centres composition equilateral triangle of three micropores, micropore and spinneret orifice 2 are all that upper end section is large, the truncated cone shape hole that lower end section is little.
Be illustrated in figure 2 a kind of embodiment of the utility model, micropore is circular micropore 4, is illustrated in figure 3 a kind of embodiment of the utility model, and micropore is triangle micropore 3, micropore and spinneret orifice 2 UNICOMs, the setting that keeps at a certain distance away of three micropores.
When the utility model work, make it pass through spinneret orifice 2 by certain speed to high polymer molten or the solution certain pressure of viscous state, on truncated cone shape spinneret orifice, end section is large, high polymer enters spinneret orifice 2 smoothly, in spinneret orifice, moving a segment distance enters respectively in three micropores, on truncated cone shape micropore, the large high polymer of end section enters micropore smoothly, and such truncated cone shape design can strengthen the degree of orientation of high polymer, makes the fibre strength of moulding higher more stable, high polymer is shaped as triangle or circle in the time that three spaced micropores spray simultaneously, at once there is swelling and being out of shape to a certain degree thereafter, particularly triangle micropore 3, the shape on three limits has certain radian, before solidifying completely, there is certain viscosity mutually at the local Adhesion formation one whole piece fiber approaching and be hollow structure at three high polymers that swell after deformation process, the fiber of hollow has advantages of that linear mass is little, and there is good thermal property, on the fabric integer of three micropore formation, be subtriangular, it has good reflective characteristic.
Three concentric circles that are made up of spinneret orifice on spinnerets body, in the time that to high polymer, pressurization is extruded, all spinneret orifices 2 are together extruded, composition mass of fibers.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
