Abstract
The utility model relates to a production big flat viscose filament yarn's spinning jet. The spinneret holes in the spinneret are special-shaped spinneret holes, the special-shaped spinneret holes are formed by connecting two arcs through two symmetrical and parallel straight lines and are dumbbell-shaped, and the spinneret holes are arranged in a crossed and parallel mode. The utility model discloses can improve the fiber end stress concentration phenomenon, reduce broken filament and broken end, improve the fibrous dysmorphism degree of platykurtic, glossiness and dyeing homogeneity, compensate prior art's the unable production of spinneret flat, the fibrous not enough of high dysmorphism degree platykurtic.
Description
Technical field
The utility model relates to the spinning head that a kind of spinning is used, and more particularly, the utility model relates to a kind of spinning head of producing big flat viscose filament yarn.
Background technology
The spinnerets hole shape of the flat viscose filament yarn of tradition is mainly rectangle, when adopting the rectangle spinnerets, the normal stress inequality of hole wall because fluid is flowed through, therefore the extrusion swelling of spin fluid is also inhomogeneous, easily cause fiber end stress concentration phenomenon, can't guarantee to spin fiber end compound with regular structure, level and smooth, thereby fiber is easy to generate lousiness and broken end in spinning and drawing process, the fiber degree of profile is generally lower, and because the difference of strand end and middle part crystalline rate causes the stock-dye inequality easily.
The utility model content
The utility model is intended to solve the defective that rectangle hole shape spinnerets easily causes fiber end stress to concentrate, make end construction comparatively regular, improve the stress concentration phenomenon of fiber end, reduce lousiness and broken end, improve degree of profile, glossiness and the dyeing uniformity of pancake fiber, remedied the deficiency that the spinnerets of prior art can't be produced flat greatly, high degree of profile pancake fiber.
To achieve these goals, concrete technical scheme is as follows:
A kind of spinning head of producing big flat viscose filament yarn is characterized in that: the spinneret orifice on the described spinning head is special-shaped spinneret orifice, and described special-shaped spinneret orifice upper and lower end is a parallel lines, and left and right end is a circular arc.
Intersect between each spinneret orifice on the above-mentioned spinning head and be arranged in parallel.
The intermediate altitude H of above-mentioned spinneret orifice is more than or equal to 0.02mm; The spinneret orifice length L is more than or equal to 0.3mm; The ratio of described spinneret orifice length L and spinneret orifice intermediate altitude H is more than or equal to 10; Described spinneret orifice two ends arc radius is more than or equal to 0.03mm.
The intermediate altitude H of above-mentioned spinneret orifice is 0.02-0.08mm; The spinneret orifice length L is 0.3-1.0mm; The ratio of described spinneret orifice length L and spinneret orifice intermediate altitude H is 10-15; Described spinneret orifice two ends arc radius is 0.03-0.08mm.
The useful technique effect that the utility model brings: improve fiber end stress concentration phenomenon, reduce lousiness and broken end, improve degree of profile, glossiness and the dyeing uniformity of pancake fiber, remedied the deficiency that the spinnerets of prior art can't be produced flat greatly, high degree of profile pancake fiber.
