Abstract
The utility model discloses a composite fiber spinneret plate, which consists of a chamber A (1), a chamber B (2), a chamber C (3) and a chamber D (4) which are sequentially connected from top to bottom. Guide holes (5) are distributed in the chamber A and the chamber B in a longitudinally penetrating way. The guide holes are in parallel with side walls of the chambers closest to the guide holes. Micro holes (6) are distributed in the chamber C and the chamber B in a longitudinally penetrating way. The micro holes are in parallel with side walls of the chambers closest to the micro holes. The guide holes and the micro holes are communicated at the junction of the chamber B and the chamber C. The diameter of the guide holes is larger than the diameter of the micro holes. The cross section of each guide hole or each micro hole is of the shape of a circular ring which is formed by three sector spinneret orifices (7) in a surrounding way, wherein openings of the sector spinneret orifices (7) face to each other and gaps (8) are kept between the end parts of every two spinneret orifices. The chamber A and the chamber C are horn-shaped chambers. The chamber B and the chamber D are cylindrical chambers. The small mouths of the chamber A and the chamber C are connected with the chamber B and the chamber D. The diameter of the chamber D is smaller than the diameter of the chamber B. The side wall (11) of the chamber A and the side wall of the chamber B form a 135-degree included angle. The side wall (31) of the chamber C and the side wall of the chamber D form a 150-degree included angle. The composite fiber spinneret plate overcomes the defects of the traditional composite spinning assembly, can be used for producing composite fibers which have the advantages of excellent elasticity and resilience force, low shrinkage rate and good hand feeling, and is suitable for high-capacity composite fiber production.
Description
Technical field
The utility model relates to a kind of composite fibre spinnerets.
Background technology
The composite spining module that uses in the conventional composite fiber, the spinneret orifice of its spinnerets mostly is the structures such as single hole, 5 holes, 7 holes, 9 holes, the hollow core staple fibers space that its spinneret orifice is produced is narrow and small and easily sunken, resilience, warmth retention property are not good, and fluidity of molten is poor during the unreasonable production composite fibre of spinneret design, is not suitable for the production of large capacity composite fibre.
The utility model content
The purpose of this utility model provides a kind of composite fibre spinnerets, and it has advantages of produces the symmetric form hollow core staple fibers that large capacity has superelevation elasticity and elasticity recovery, hangs down retraction, good feel.
This composite fibre spinnerets, consisted of by cavity A, the cavity B, cavity C and the cavity D that connect successively from top to bottom, vertically connect in cavity A, the cavity B and be distributed with guide hole, guide hole is parallel to apart from its nearest cavity wall, vertically connect in cavity C, the cavity D and be distributed with micropore, micropore is parallel to apart from its nearest cavity wall, guide hole is connected with the junction of micropore at cavity B, C, the aperture of guide hole is large than micropore, and guide hole and micropore cross section are that 3 fan-shaped spinneret orifice opening directions are relative to be surrounded as annular and to leave the space between the spinneret orifice end in twos.There are enough degree of hollowness the composite fibre inside that is arranged so that of 3 spinneret orifices, fan-shaped design so that composite fibre be difficult for subsiding, therefore composite fibre has good elasticity and resiliency, good hand touch, saves 20% so that fill the composite fibre use amount of same volume than conventional doughnut.The long-neck ratio that is arranged to regulate melt of micropore, thereby the thickness of control composite fibre.
Cavity A, cavity C are tubaeform cavity, cavity B, cavity D are circular cylindrical cavity, and the osculum of cavity A, cavity C is connected with cavity B, cavity D respectively, and cavity D diameter is less than cavity B diameter, the sidewall of cavity A and cavity B sidewall are 135 °, and the sidewall of cavity C and cavity D sidewall are 150 °.Mobile shear stress experiment draws the Sidewall angles of cavity A and cavity C through PET, with this angle PET melt preferably mobile and sufficient stress relaxation can be arranged, the expanded ratio that obtains being fit to, thereby reduce melt bonds plate face, be conducive to carrying out smoothly of spinning, make this spinnerets be applicable to the large capacity production of composite fibre.

The specific embodiment
Now provide embodiment describing a kind of composite fibre spinnerets of the present utility model in detail, specific as follows:
Shown in Fig. 1～3, a kind of composite fibre spinnerets is made of cavity A1, the cavity B2, cavity C3 and the cavity D4 that connect successively from top to bottom.Cavity A, cavity C are tubaeform cavity, cavity B, cavity D are circular cylindrical cavity, and the osculum of cavity A, cavity C is connected with cavity B, cavity D respectively, and cavity D diameter is less than cavity B diameter, sidewall 11 and the cavity B sidewall of cavity A are 135 °, and sidewall 31 and the cavity D sidewall of cavity C are 150 °.Vertically connect in cavity A, the cavity B and be distributed with guide hole 5, guide hole is parallel to apart from its nearest cavity wall, vertically connect in cavity C, the cavity D and be distributed with micropore 6, micropore is parallel to apart from its nearest cavity wall, guide hole is connected with the junction of micropore at cavity B, C, and the aperture of guide hole is large than micropore.As shown in Figure 4, guide hole or micropore cross section are that 3 fan-shaped spinneret orifice 7 opening directions relatively are surrounded as annular and leave in twos space 8 between the spinneret orifice end.
The course of work of composite fibre spinnerets of the present utility model: be imported into respectively in the guide hole of spinnerets through two kinds of melts after a plurality of distribution plates distribution, because 2 in 3 spinneret orifices of guide hole are symmetrical with respect to distribution plate, another spinneret orifice self is symmetrical with respect to the intersection of distribution plate, two kinds of melts are divided into 3 lobes by each guide hole, and melt does not interfere with each other by three lobes channel flow separately.Guide hole is connected with micropore, and melt still is 3 lobes after entering micropore by guide hole, but because the aperture diminishes from top to bottom gradually, melt is adjusted to required long-neck and compares specification.As shown in Figure 5, after melt is extruded from micropore, melt in 3 spinneret orifices of each micropore is because phenomenon and bonding is expanded in the special outlet of macromolecular material, thereby formation doughnut, again because the property difference of two kinds of melts produces stress relaxation difference by same extrusion condition and cooling stretching condition, finally cause fiber to form curling, make the symmetric form composite fibre.
