Abstract
The invention discloses a T-shaped polyester fiber spinneret plate which is balanced in pressure, high in deformability rate and good in spinning effect. The T-shaped polyester fiber spinneret plate comprises a body and a plurality of small spinneret holes formed in the lower end face of the body, the section of each small spinneret hole is in a T shape, and the small spinneret holes are arranged in a radiating shape, center lines of the T-shaped longitudinal small holes pass through the center of the body, the length ratio of the T-shaped longitudinal small holes and the horizontal small holes is 1.2 to 1.5, melt guiding holes are formed in the upper portions of the small spinneret holes, and melt guiding grooves are connected to the upper ends of the melt guiding holes.
Description
Technical field
The present invention relates to a kind of melt spinning equipment, relate in particular to the spinnerets that a kind of T of being suitable for font polyster fibre is produced.
Background technology
The wearability of ordinary polyester fiber is poor, easily produces sultry, the air-locked sensation of skin, thereby cannot meet the wearing comfort requirement of people for chemical fibre textile.And change fibre section structure, and make fiber surface produce trickle groove, through wicking, produce good moisture absorption, wet guiding function, thereby improve fabric breathability, improve fabric level of comfort.The effect of spinnerets is by the high polymer molten of viscous state or solution, be transformed into the thread that has particular cross section shape by micropore, be solidified to form strand through setting medium as air or coagulating bath, thereby in spinnerets, the cross sectional shape of spinneret orifice is the key that determines fibre section shape, and it is common cross, Y type, T-shaped, triangular form, although the heterotypic fibre wet transmitting performances such as H type are significantly improved with respect to general fibre, but effect or not ideal enough, and the cross sectional shape of spinneret orifice is more complicated, spinning difficulty is larger, especially common spinnerets cannot ensure the uniformity of each spinneret orifice internal pressure, thereby cause affecting stability of spinning process.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of isostasy, special-shaped rate is high, spinning effect is good T font polyster fibre spinnerets.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The present invention includes body, be located at some spinneret orifices of body lower surface, the cross sectional shape of described spinneret orifice is T font, described spinneret orifice is arranged radially, the longitudinal micropore center line of described T font is by body center, the longitudinal micropore of described T font is 1.2～1.5 with horizontal micropore Length Ratio, described spinneret orifice top is provided with melt guide hole, and described melt guide hole upper end connects melt guide groove.
As preferably, described melt guide hole is rounding frustum, and described melt top of guide slot is provided with melt distributing trough.
The present invention compared with prior art, has following obvious advantage and beneficial effect:
1, isostasy.Because the present invention is by setting up melt distributing trough and melt guide groove, make melt first in melt distributing trough, enter distribution entering before melt guide hole, melt pressure is balanced, and again carry out isostasy by melt guide groove, thereby the melt pressure of melt in melt guide hole is consistent, is conducive to improve spinning quality.
2, special-shaped rate is high.Due to longitudinally micropore and the laterally larger gap design of micropore length dimension employing in T font spinneret orifice of the present invention, avoid longitudinal micropore inter-adhesive in spinning process with horizontal micropore, thereby improve special-shaped rate.
3, spinning effect is good.Because spinneret orifice of the present invention is arranged radially, melt guide hole is rounding frustum, not only make strand cooling evenly, and fluidity of molten is good, thereby improves spinning effect.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail:
As shown in Figures 1 to 4: the present invention includes body 1, be located at some the spinneret orifices 2 of body 1 lower surface, the cross sectional shape of spinneret orifice 2 is T font, spinneret orifice 2 is arranged radially, the longitudinal micropore center line of T font is by body center, the longitudinal micropore 21 of T font is 1.2～1.5 with horizontal micropore 22 Length Ratios, and spinneret orifice 2 tops are provided with melt guide hole 3, and melt guide hole 3 is rounding frustum, melt guide hole 3 upper ends connect melt guide groove 5, and melt guide groove 5 tops are provided with melt distributing trough 6.
Claims (2)
