The fiber yarn spun by the spinneret plate is H-shaped, and gaps exist among the monofilaments, so that the spinneret plate has good elasticity and bulkiness. Three types of special-shaped hole combined spinneret plates are disclosed in Chinese patent publication No. CN209685962U, wherein the H-shaped hole type special-shaped spinneret plate is also used for one type of special-shaped holes.
However, the bulk of the filaments produced by the spinneret plate using the above-mentioned H-shaped spinneret orifices is not theoretically good, because: after the raw materials are sprayed out of the spinneret holes, puffing phenomenon can occur, two ends of the H-shaped monofilaments can be protruded, gaps between the H-shaped monofilaments can be reduced, the protruded portions of the two ends of the H-shaped monofilaments can be filled into the gaps between the H-shaped monofilaments, as shown in fig. 1, so that the hollowness of the final fiber yarn can not reach a theoretical value, the elasticity and the bulking degree of the fiber yarn are affected, and the moisture absorption and sweat release properties of the fiber yarn are also affected.

Preferably, the end through holes are of symmetrical structures, and the symmetrical line of the end through holes coincides with the central line of the long strip through holes in the length direction.
Preferably, the concave part is an arc-shaped concave.
Preferably, the concave depth of the concave part is 1/4 of the width of the through hole at the end part, so that the end part of the monofilament is in a flat structure or a concave structure after the raw materials are sprayed and puffed from the spinneret orifice.
Preferably, the center line of the end through hole in the length direction coincides with the center line of the long strip through hole in the length direction.
Preferably, the spinneret orifices are uniformly distributed along the inner and outer circumferences.
Compared with the prior art, the technical scheme provided by the utility model has the following beneficial effects:
the utility model relates to a fluffy high-elasticity moisture-absorbing and sweat-releasing fiber spinneret plate, wherein a discharge hole of a spinneret orifice comprises a strip-shaped through hole and end through holes arranged at two ends of the strip-shaped through hole, the width of each end through hole is larger than that of the strip-shaped through hole, a concave part is arranged at one side of each end through hole far away from the strip-shaped through hole, raw materials are puffed when being sprayed out from the spinneret orifice, and the concave part is arranged at one side of each end through hole far away from the strip-shaped through hole, so that the end part of a puffed monofilament is in a flat structure or a concave structure, and therefore, after a plurality of monofilaments are bonded together, the end part of one monofilament cannot fill the gap between two end hole ejection parts of the other monofilament, the pores of the finally obtained fiber are ensured to be larger, and the fluffiness, the elasticity and the moisture absorption and sweat release of the fiber are improved.
