Abstract
The utility model provides a spinneret plate for a cross-shaped hollow fiber. The cross section of a silk hole is cross-shaped which is formed by four line-shaped holes and every two adjacent line-shaped holes of the four line-shaped holes intersect in a perpendicular mode. The sizes and the shapes of the four line-shaped holes are exactly the same. Two ends of each line-shaped hole are both arc-shaped, namely semicircles. The length of each line-shaped hole is 0.1-0.5mm. The width of each line-shaped hole is 0.04-0.16mm. The length of the formed corresponding cross-shaped silk hole is 0.25-12mm. An included angle between a center axis of a line-shaped hole of the cross-shaped silk hole and a connecting line between a center point P of the cross-shaped silk hole and the center O of the spinneret plate is alpha, and the alpha is 15-75 degrees. The number of the holes of the spinneret plate is 1000-2500. Routine cone-shaped guide holes are adopted, the fiber is produced through matched spinning and drafting technologies, wherein a cross section of the fiber is in a cross-shaped hollow shape. Due to the fact that a special shape and the cavity exist, the fiber product is enabled to have excellent performance of a cross-shaped fiber and a hollow fiber, the cross-shaped hollow fiber has numerous advantages of having wet permeability and air permeability, being fluffy, keeping warm, being full in handle, and the like. Compared with an ordinary special-shaped fiber, the cross-shaped hollow fiber is better in performance.
Description
Technical field
The utility model relates to a kind of cross-shaped hollow type profiled filament and spinning used spinnerets, particularly polyester staple fiber and used spinnerets thereof.
Background technology
Since 50 years du pont companies are released the triangular-section fiber, profiled filament has obtained fast development, developed into the higher profiled filaments of production difficulty such as pentagon, M shape, cross and multiple hollow shape from triangle, trilobal and hollow shape, the heteromorphosis of fibre section can be improved glossiness, bulkiness, anti-fluffing, pilling tendency, hygroscopicity, resistance to soiling, stiffness, elasticity and the feel of textile product to a certain extent.
But only rest in the production of common profiled filament at present, the dual-use function that the Complex Different Shape fiber has profiled filament and doughnut concurrently still is in the stage to be developed at present.
Summary of the invention
The utility model provides the spinnerets in a kind of cross-shaped hollow type silk hole, through supporting spinning and draft process and produce the fiber that its cross section is the cross-shaped hollow type, for achieving the above object, the utility model spinnerets silk hole Cross section Design following technical scheme:
(1) silk cross section, hole be four yi word pattern holes in twos adjacent intersecting vertically consist of the cross shapes of hollow, four yi word pattern hole sizes and shape are identical.Two ends, yi word pattern hole are circular-arc, be semicircle, the yi word pattern hole length is 0.1mm～0.5mm, width is 0.04～0.16mm, the length that forms corresponding cross silk hole is 0.25mm～1.2mm, angle between the central axis in yi word pattern hole wherein, cross silk hole and the center point P in cross silk hole and the spinnerets center O line is α, and α is 15 °～75 °, adopts conventional taper guide hole;
(2) arranged distribution in cross-shaped hollow type silk hole is: be the multilayer concentric circle at spinnerets and distribute, the adjacent holes spacing equates;
(3) spinneret orifice on the spinnerets is 1000～2500 holes.
The beneficial effects of the utility model are, owing to adopted the spinnerets in cross-shaped hollow type silk hole, change the fibre section shape, so that the fibre section that is spun into is the cross-shaped hollow shape, because the existence of abnormity and cavity, so that this fiber product has the premium properties of cross fiber and doughnut concurrently in one, have and lead the many merits such as moist, gas permeability, fluffy, warming, good hand feeling, performance is better than common profiled filament.
