Description
Technical field
The utility model is related to spinning field more particularly to a kind of terylene spinnerets with disloyalty C-shaped spinneret orifice.
Background technology
Existing crimped fibre mostly carries out laminating production, such as Application No. using two kinds and more than component
The Chinese patent of CN200820036336.3 discloses a kind of spinning nozzle, including spinneret, is offered on the spinneret
The axial line of first component spinneret orifice and the second component spinneret orifice, the axial line of the first component spinneret orifice and the second component spinneret orifice
Intersect in place outside spinneret.The spinning nozzle is simple in structure, suitable for producing various parallel composite fibers, and produces
The distinct of the parallel composite fiber gone out has different crimp property.
Since the property of two-component materials is different, the fiber sprayed can be formed the silk that the two-component spinneret orifice sprays
Curling.But the technique productions flow is cumbersome and with high costs.It is therefore desirable to develop one kind only to need one pack system that can just give birth to
Produce the spinneret of crimped fibre.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of terylene spinneret with disloyalty C-shaped spinneret orifice
Plate.The spinneret of the utility model can realize that the excellent polyester fiber of crimpiness is made in one pack system spinning solution spinning.
The specific technical solution of the utility model is：A kind of terylene spinneret with disloyalty C-shaped spinneret orifice, including spinneret
Plate body and several spinneret orifices on the spinnerette body, width is presented in the longitudinal cross-section of the input end of the spinneret orifice
Under it is narrow trapezoidal, the radial section of the port of export of the spinneret orifice is in disloyalty C-shaped, and the opening of all disloyalty C-shapeds is towards spinneret
The direction of cross air blasting in the process；The center of circle of the spinneret orifice is distributed in concentric circles at least two concentric circles, positioned at different circles
On spinneret orifice be staggered in a circumferential direction, and the center of circle of two neighboring spinneret orifice and the spinneret center of circle in a circumferential direction
Line angle be 3-15 degree.
Common C-shaped spinneret orifice is widely used in spinning spinneret, but common C-shaped spinneret orifice, which has no legal system, to be rolled up
Bent fiber of good performance.In order to realize that one pack system spinning solution can also produce the good fiber of crimpiness, the present invention devises
The spinneret orifice of disloyalty C-shaped.Its principle is that spinning solution is after portalling, and due to the design of disloyalty spinneret orifice, the fiber of formation is in C-shaped
Openend at form gap, the stress for causing fibrous inside is different, so as to generate curling in the axial direction.By c-shaped opening direction
The reason for cross air blasting direction, is that the crystallinity of its windward side and leeward generates difference to fiber while cooling, so as to favourable
In further crimping fiber.By the binding clip in the center of circle of two neighboring spinneret orifice in a circumferential direction and the spinneret center of circle
Angle is 3-15 degree, and reason is that the tow that above-mentioned angle can be ensured that each spinneret orifice comes out can be effectively cold by cross air blasting
But.
Preferably, the internal diameter of the disloyalty C-shaped is 0.7mm, outer diameter 1.0mm, the air line distance at the both ends of opening is
0.2mm, line between the outer center of circle and the interior center of circle of disloyalty C-shaped are the perpendicular bisector of the line at the opening both ends of disloyalty C-shaped, outer circle
The heart is with inner circle in the heart away from 0.1mm.
The present inventors have additionally discovered that and the spinneret orifice of not all disloyalty C-shaped the excellent fiber of crimpiness can be made.For
Further improve fibre crimpn, the present inventor strictly limits the shape of disloyalty C-shaped, in above-mentioned qualifications
Under, fibre crimpn obtained is optimal.
Preferably, the hole count of the spinneret orifice is 24-96.
Preferably, the number of turns of the concentric circles is 2-4, and the radial distance between neighboring concentric circle at least above
10mm。
Preferably, the draw ratio of the port of export in disloyalty C-shaped of the spinneret orifice is 0.5-2.0.
It is compared with the prior art, the beneficial effects of the utility model are：
（1）Produced crimped fibre is one-component.
（2）It may be such that the fracture of terylene crimped filament stretches the range-controllable system of rate 23% using the terylene crimped filament of its production
To 32%, intensity is in 3.0CN/dtex to 4.1CN/dtex.
（3）So that the shape integrity of C shapes reaches 100%, it is not open the problem of unclear.
（4）For workable Denier range in 50dtex to 150dtex, radical is 24 to 96.
