Abstract
The utility model specifically discloses a kind of spinnerets, and described spinnerets is oval, comprises spinnerette body, spinnerette body is provided with spinneret orifice; Spinnerette body is provided with one and by the peripheral air channel led in the middle part of spinnerets of spinnerets, the spinnerette body in region, air channel can arrange spinneret orifice; Described spinneret orifice comprises guide hole import counterbore, the lower end of guide hole import counterbore is communicated with for guide hole, the microporous connectivity in guide hole and spinneret orifice; The spinneret orifice of the described lower regions separated by air channel is connected by reinforcement in respective region.The high-temperature fusant that described spinnerets sprays reaches technological requirement with certain whole uniform cooling in journey of spinning and forms the stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree in official hour, thus makes spinning effect better.
Description
Technical field
The utility model relates to field of textiles, particularly relates to a kind of spinnerets.
Background technology
Spinnerets is also known as spinning cap, the high polymer molten of viscous state or solution can be transformed into the thread having particular cross section shape by spinnerets by spinneret orifice, strand is formed after setting medium is as air or coagulating bath solidification, the spinnerets of current production dawn silk is generally circular, during lateral blowing, wind area is little, ventilative weak effect, cooling effect is not good, can produce the problem that the broken end of fiber, lousiness and Color are uneven.
Because the diameter of spinnerets is comparatively large, tow is many, and the peripheral tow that cooling air is difficult to through gathering layer by layer arrives in the middle part of spinnerets, and the tow be positioned in the middle part of spinnerets because cooling does not reach technological requirement, and can cause difficulty in spinning, affects product quality.
Simultaneously common spinneret orifice of the prior art, is generally straight-through flexible, is unfavorable for that melt distributes even, while melt outlet place there is the phenomenon that swells, even melt fracture, causes broken end.
Utility model content
The utility model is exactly the deficiency that will overcome existing spinnerets, provides a kind of spinnerets, and it is little that this spinnerets can solve wind area when crosswind blows, ventilative weak effect, not good the asking of cooling effect; Make the tow in the middle part of spinnerets also can reach the requirement of process for cooling, strengthen spinning effect; Solve the problem of phenomenon that the uneven and melt of melt often breaks end and spinnerets insufficient strength simultaneously.
The utility model have employed following technical scheme:
A kind of spinnerets, described spinnerets is oval, comprises spinnerette body (1), spinnerette body (1) is provided with spinneret orifice (2); Spinnerette body (1) is provided with one and by the peripheral air channel (3) led in the middle part of spinnerets of spinnerets, the spinnerette body in region, air channel can arrange spinneret orifice; Described spinneret orifice (2) comprises guide hole import counterbore (4), the lower end of guide hole import counterbore (4) is communicated with for guide hole (5), and guide hole (5) is communicated with the micropore (6) in spinneret orifice (4).
Further, the pitch-row such as described spinneret orifice (2) arrangement.
Further, between described guide hole (5) and micropore (6), be provided with guide hole cone angle (7), described guide hole cone angle (7) be communicated with guide hole (5) and be communicated with micropore (6).
Further, the diameter of described micropore (6) is 0.25mm ~ 0.45mm.
The utility model beneficial effect is compared with prior art:
The high-temperature fusant that spinnerets can be made to spray reaches technological requirement with certain whole uniform cooling in journey of spinning and forms the stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree in official hour, thus makes spinning effect better; Body due to spinnerets is oval, and during lateral blowing, wind area is large, and outlet tow cooling is even, not easily occurs the breakage phenomena of fiber, effectively can improve Color; The structure of spinneret orifice ensure that melt flows is even simultaneously, and product quality significantly improves.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is spinneret pore structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, a kind of spinnerets is described further.
Shown in composition graphs 1, Fig. 2, a kind of spinnerets, described spinnerets is oval, comprises spinnerette body 1, spinnerette body 1 is provided with spinneret orifice 2; Spinnerette body 1 is provided with one and by the peripheral air channel 3 led in the middle part of spinnerets of spinnerets, the spinnerette body in region, air channel can arrange spinneret orifice; Described spinneret orifice 2 comprises guide hole import counterbore 4, the lower end of guide hole import counterbore 4 is communicated with for guide hole 5, and guide hole 5 is communicated with the micropore 6 in spinneret orifice 4.
Further, the pitch-row such as described spinneret orifice 2 arrangement.
Further, between described guide hole 5 and micropore 6, be provided with guide hole cone angle 7, described guide hole cone angle 8 be communicated with guide hole) be communicated with micropore 6.
Further, the diameter of described micropore 6 is 0.25mm ~ 0.45mm.
Description for the understanding of detailed description of the invention be only for help understand the utility model, instead of be used for restriction of the present utility model.Those skilled in the art all can utilize thought of the present utility model to carry out some and change and change, as long as its technological means does not depart from thought of the present utility model and main points, still within protection domain of the present utility model.
