Abstract
The utility model provides a kind of a kind of spinneret of annular special doughnut in synthetic fibers shaped device field, including plate body, there are some spinneret orifices in array distribution on the plate body, the spinneret orifice includes the introduction segment of entrance location and the capillary section of outlet port, introduction segment corresponds with capillary section to be connected, the outer rim of the introduction segment and capillary section section is circle, introduction segment first gradually tapers up from the top down with capillary section link position, gradually amplification again, the capillary section center is provided with the spreader of more prismatics, it is connected between spreader and the inwall of capillary section through dowel.The petal-shaped abnormity hollow core staple fibers spinned using the utility model spinneret, not only there is preferable warmth retention property, refractivity, crimpiness and bulkiness, but also have the advantages that degree of hollowness is high, specific surface area is big, moisture absorbing and sweat releasing, it is ventilative it is comfortable, feel is smooth, product can be used for inserts and spinning.
Description
Technical field
It the utility model is related to a kind of spinneret for producing fiber, more particularly to a kind of special-shaped hollow rejuvenation polyester staple fibers
The spinneret of Wesy, belong to synthetic fibers field shaping technique.
Background technology
Polyester high polymer molten is mainly passed through C-shaped or double arcuate slots by the spinneret of recycled polyester hollow core staple fibers
Die capillaries be transformed into the thread of rounded hollow sections shape, be then processed into hollow core staple fibers by cooled and solidified again.
The spinneret of existing spinning recycled polyester hollow core staple fibers is generally in the majority with the circular spinneret orifice of design, and generally use is such
Not only rigidity is big for the circle hollow core staple fibers of spinneret spinning, and soft resilience is poor, and glossiness and moisture absorbing and sweat releasing effect are not
Good, product can typically be only used to inserts.
Utility model content
The purpose of this utility model is to provide a kind of spinneret of annular special doughnut, returns its fiber produced
Elastic height, specific surface area are big, hygroscopicity rate is high.
Therefore, the technical solution that the utility model uses is：A kind of spinneret of annular special doughnut, bag
Rubbing board body, has some spinneret orifices on the plate body in array distribution, and the spinneret orifice includes introduction segment and the outlet of entrance location
The capillary section of position, introduction segment corresponds with capillary section to be connected, and the outer rim of the introduction segment and capillary section section is circle,
Introduction segment first gradually tapers up from the top down with capillary section link position, then gradually amplification, and the capillary section center is provided with more prismatics
Spreader, be connected between spreader and the inwall of capillary section through dowel.
The design that the device passes through spinneret orifice so that from capillary section extrusion after fiber cross-sectional be in hollow annular, process
After spreader, rib is internally formed spacing, makes it have good compressibility, in being spinned using the utility model spinneret
Hollow fiber, resilience is good, specific surface area is big, moisture absorbing and sweat releasing, feel are smooth, and with preferable warmth retention property, refractivity, curling
Property and bulkiness, product both can be used as filler, can be used for spun yarn again.
It is as further improvement of the utility model, at least four, the rib outside the spreader, the dowel
Correspond and be connected with the outer rim of the rib.
To ensure that spinning elasticity is good, the side of the rib is curved.
Further to improve the elasticity of spinning, the periphery of capillary section is arranged at intervals the projection of oriented center extension.Polyester melts
Body can form groove in spinning surface, make it have more preferable compressibility after projection.
It is that the radius of circumference is where the spreader lower end rib top as further improve of the present utility model
0.25 ~ 0.5mm, the overall radius of mouth is 0.75 ~ 1.25mm under the capillary section, and the width of dowel is 0.02mm, raised
Width 0.01mm.The spinneret of the structure is applied to production regenerative polyester staple fiber.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model spinneret.
Fig. 2 is the longitudinal profile structure schematic of spinneret orifice.
Fig. 3 is Fig. 2 A to structural representation.
In figure：1 plate body, 2 introduction segments, 3 capillary sections, 4 spreaders, 5 is raised, 6 dowels.
Embodiment
As Figure 1-3, it is a kind of spinneret of annular special doughnut, if having on its plate body 1 in array distribution
Dry spinneret orifice, spinneret orifice include the introduction segment 2 of entrance location and the capillary section 3 of outlet port, and introduction segment 2 and capillary section 3 are one by one
Corresponding to be connected, the outer rim of introduction segment 2 and the section of capillary section 3 is circle, and introduction segment 2 and the link position of capillary section 3 are from the top down
First gradually taper up, then gradually amplification, the center of capillary section 3 is provided with the spreader 4 of more prismatics, the inwall of spreader 4 and capillary section 3 it
Between through dowel 6 be connected；At least four, rib outside spreader 4, can be five, six, eight etc., the side of rib is curved,
Dowel corresponds with the outer rim 6 of rib to be connected, and the width of dowel 6 is 0.02mm.The periphery of capillary section 3 is arranged at intervals oriented
The projection 5 of center extension, the width 0.01mm of projection 5.The radius R1 of circumference where the lower end rib top of spreader 4 for 0.25 ~
0.5mm, the overall radius R2 of 3 times mouths of capillary section is 0.75 ~ 1.25mm.
Using the utility model spinneret spin petal-shaped abnormity hollow core staple fibers, not only with preferable warmth retention property,
Refractivity, crimpiness and bulkiness, but also with degree of hollowness is high, specific surface area is big, moisture absorbing and sweat releasing, it is ventilative it is comfortable, feel is suitable
The advantages that sliding, product can be used for inserts and spinning.
The utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can is special to some of which technology
Sign makes some and replaces and deform, and these are replaced and deformed in the scope of protection of the utility model.
