Abstract
The utility model relates to a kind of spinnerets, comprise plate body (1), plate body (1) is provided with the spinneret orifice that several run through plate body, described spinneret orifice is comprised of the coaxial guide hole (2) setting gradually from top to bottom and pore (3), the draw ratio of pore (3) is 15:1, and the diameter of pore (3) is 0.2-0.3mm.The utility model, by changing aperture and the draw ratio of the pore of spinneret orifice on spinnerets, can improve spray silk speed and draw speed, greatly enhances productivity; Meanwhile, the spinning surface smoothness that adopts this spinnerets to produce is high, and string diameter is ultra-fine, can reduce product substance like this, has reduced filling cost, thereby has greatly increased economic efficiency.
Description
Technical field
The utility model belongs to spining technology field, is specifically related to a kind of spinnerets.
Background technology
Polyester staple fiber is the important kind of synthetic fiber, and it is a kind of important textile raw material.Regenerative polyester staple fiber refers to the staple fibre that the waste and old polyester raw material of processing is used and again produces, and can reduce costs, and realizes resource reutilization, is conducive to environmental protection.
While producing polyester staple fiber at present, conventional spray silk machine is realized spinning, the spinning pack of spray silk machine comprises spinnerets, spinnerets is provided with guide hole and the pore (being wire vent hole) that runs through plate body, but the aperture of the spinnerets of normally used spray silk machine is partially thick, for example the diameter of cylindrical guide hole is 3mm, the diameter of pore is 0.3mm, because aperture is partially thick, cause spray silk speed on the low side, draw speed is also partially slow, spray silk draw ratio is 1:80, product string diameter is partially thick simultaneously, has not only increased product substance but also can not give full play to heat-insulating property, and cost performance is low.
Utility model content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of spinnerets, uses this spinnerets, and spray silk speed is high, and draw speed is fast, can obtain the fiber product that string diameter is ultra-fine, cost performance is high.
For reaching above object, the technical solution adopted in the utility model is: a kind of spinnerets, comprise plate body, plate body is provided with several spinneret orifices that runs through plate body, described spinneret orifice is comprised of the coaxial guide hole and the pore that set gradually from top to bottom, the draw ratio of pore is 15:1, and the diameter of pore is 0.2-0.3mm.
Further, guide hole is formed by connecting by the upper round taper hole setting gradually from top to bottom, cylindrical hole and lower round taper hole.
Further, the diameter of the cylindrical hole of guide hole and the diameter ratio of pore are 15:1.
The utility model, by changing aperture and the draw ratio of the pore of spinneret orifice, can improve spray silk speed and draw speed, greatly enhances productivity; Meanwhile, the spinning surface smoothness that adopts this spinnerets to produce is high, and string diameter is ultra-fine, can reduce product substance like this, has reduced filling cost, thereby has greatly increased economic efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the spinneret orifice of the spinnerets that provides of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, a kind of spinnerets provided by the utility model, comprise plate body 1, plate body 1 is provided with several spinneret orifices that runs through plate body, described spinneret orifice is comprised of the coaxial guide hole 2 setting gradually from top to bottom and pore 3, the draw ratio of pore 3 is 15:1, and the diameter d of pore 3 can be 0.2-0.3mm.Here, the draw ratio of pore 3 refers to the ratio of length L and the diameter d of pore 3.
Under preferable case, the diameter d of pore 3 is 0.2mm, and length L is 3mm.
In the utility model, the shape of guide hole 2 can adopt existing various shape, as cylindrical, conical, the hyperboloid type at the band cone end or flat cylindrical.For example, guide hole 2 can be formed by connecting by the upper round taper hole 2-1, the cylindrical hole 2-2 that set gradually from top to bottom and lower round taper hole 2-3.
Under preferable case, the diameter D of the cylindrical hole 2-2 of guide hole 2 is 15:1 with the ratio of the diameter d of pore 3.For example, the diameter d of pore 3 is 0.2mm, and the diameter D of the cylindrical hole 2-2 of guide hole 2 is 3mm.
The utility model in use, enters in the guide hole 2 (cylindrical hole Φ 3mm) of spinnerets the polyester fondant after melting, under the effect that melt is exerted pressure outside, by spinnerets, by pore 3 (Φ 0.2mm), is emitted into silk.It is as-spun fibre that the Polyester Filament spraying at a high speed from spinnerets is drawn at a high speed cooling forming, and ejection draw ratio is 1:120.
Structure described in the utility model is not limited to the embodiment described in the specific embodiment, and those skilled in the art draw other embodiment according to the technical solution of the utility model, belongs to equally technological innovation scope of the present utility model.
