Problems solved by technology
It can be seen that the A component flowing out of the small hole will tend to flow in the nearby component A diversion groove. Therefore, the flow rate will be slow or even piled up at the edge of the outlet groove of component A and the junction of adjacent small holes, and it will stay for a long time Carbonization will occur, causing the outlet groove of component A to be blocked, thereby affecting the production quality

The invention discloses a core plate and a spinneret plate assembly of a split type double-component composite fiber. A plurality of A component guide grooves and a plurality of B component guide grooves are formed in the upper surface of the core plate, the A component guide grooves and the B component guide grooves are arranged at intervals, a plurality of double-component outlets are formed in the lower surface of the core plate, and first through holes and second through holes are connected with the double-component outlets; and each double-component outlet comprises a plurality of A component outlets concavely formed in the lower surface of the core plate and B component diversion trenches, the A component outlets and the B component diversion trenches are arranged at intervals according to the circumference, and drainage grooves connected with the B component diversion trenches and the first through holes are concavely formed in the lower surface of the core plate. Directional supply of components B is achieved by arranging the drainage grooves, the problem of balance of melt runners is solved, the runner retention phenomenon is greatly improved, the stability of fiber quality is improved, and the quality of composite fibers is guaranteed; and the staying time of the melt on the core plate is kept constant, and the product quality is stable.
Description
technical field [0001] The invention relates to the field of fiber manufacturing, in particular to a core plate and a spinneret assembly of split-type bicomponent composite fibers. Background technique [0002] The cross-sectional shape of each monofilament in the split-type polyester-nylon bicomponent composite fiber is circular or basically circular; among them, the strip-shaped part that runs radially through the cross-section is nylon, and the rest is completely separated by nylon The open part is polyester. [0003] In the production practice of the currently adopted core board structure, we found that the quality of the P-shaped composite fibers produced is not very stable. The melt of the nylon melt enters the strip part at a high speed before the melt has a slow flow rate or even piles up. The place is easy to stay for a long time and will cause carbonization, which will eventually cause local blockage and seriously affect the product quality. [0004] Chinese pate...
