The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment in the utility model can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.
According to the spinnerets of the utility model embodiment, it is provided with one or more spinneret orifices road, usually, 1～144 spinneret orifice road can be set on the spinnerets.When spinneret orifice road when being a plurality of, can the spinneret orifice road be arranged on the spinnerets regularly according to design in advance.10,72 spinneret orifice roads 20 of spinnerets as shown in Figure 1 can circularize being arranged on the spinnerets 10 of rule.
As shown in Figure 2, spinneret orifice road 20 comprises that top and bottom are respectively arranged with the guide hole 21 of guiding funnel structure and the spinneret orifice 22 of the below of the lower end funnel structure that is arranged on guide hole 21.Because guide hole 21 has the guiding funnel structure, make that the resistance when polymer melt gets into spinnerets is less, and the dynamics during the spray silk is bigger, thereby can increases the intensity of fiber, improve quality of fibre.Spinneret orifice 22 is made up of one or more spray silk micropores 221, preferably, is made up of 1～9 spray silk micropore 221, has so both guaranteed the ability of the fiber-loaded functional materials of container function, has guaranteed the spinnability of container function fiber again.This spray silk micropore 221 is the annulars that surrounded by one or more spray silk micropore section 222, forms one first breach d1 at least between the end of spray silk micropore section 222.Wherein, The first breach d1 is meant and can makes the container function fiber of producing through the spinnerets of the utility model have the distance of axial surface opening; Usually; The first breach d1 is 0.01～3mm, and greater than the diameter that will be carried on the functional particles in the container function fiber, the container function fiber of producing like this is convenient to packing into of functional materials.With after-drawing and/or reverse the container function fiber, make through hole dwindle at container function fiber surface opening, functional materials is encapsulated in the through hole.When spray silk micropore 221 is a plurality of; Can become delegation, two row or annular array; And the position of the first breach d1 in each spray silk micropore 221 is set to the geometric outside that forms towards by these a plurality of spray silk micropores 221, is convenient to the inside of functional character entering container function fiber.Distance between adjacent spray silk micropore 221 neighboring edges can be between 0.01～1mm, the filament adhesion of being convenient to the processing of spinnerets 10 and preventing to spray.Can also form one or more second breach d2 between the end of spray silk micropore section 222; Wherein, The second breach d2 is meant after polymer melt sprays from adjacent spray silk micropore section 222; Because polymer melt has certain coefficient of expansion, the distance that the polymer melt that adjacent spray silk micropore section 222 is sprayed is sticked together.The fiber assymmetrical deformation that the second breach d2 can prevent that polymer melt ejection back from causing owing to the existence of the first breach d1 is set, so can prevent fiber axis to through-hole structure size and axial surface opening size variation; The second breach d2 of adjacent spray silk micropore 221 certain distance that can stagger, the adhesion during the container function fiber that prevents to form between the adjacent fiber silk.Characteristic according to the polymer melt that forms fiber; Spray silk micropore 221 circumscribed circle diameters can be 2～30: 1 with the ratio of annular width; The length ratio of spray silk micropore 221 circumscribed circle diameters and the first breach d1 is that the longest ratio with beeline is 1～30: 1 between the geometric center of 0.5～30: 1, the first breach d1 and the second breach d2, and one side can make the container function fiber have bigger container function; Guaranteed the intensity of container function fiber on the other hand, made it have spinnability.Further, the outline line of spray silk micropore 221 can be circle, ellipse or polygon.
As shown in Figure 3; The outline line of spray silk micropore 221 is circular in the present embodiment, and the distance between adjacent spray silk micropore 221 neighboring edges is 0.05mm, has one first breach d1 and two second breach d2; The length of the first breach d1 is 0.2mm, and the length of the second breach d2 is 0.05mm.Spray silk micropore 221 circumscribed circle diameters can be 3: 1 with the ratio of annular width, 221 one-tenth several rows of row of 6 spray silk micropores, and the position of the first breach d1 is located at the side of row.
As shown in Figure 4; The outline line of spray silk micropore 221 is can be circular in other embodiment of the utility model; Between adjacent spray silk micropore 221 neighboring edges is 0.12mm apart from d3; Have one first breach d1 and two second breach d2, the length of the first breach d1 is 0.2mm, and the length of the second breach d2 is 0.05mm.Spray silk micropore 221 circumscribed circle diameters are 3: 1 with the ratio of annular width, and 6 spray micropores 221 one-tenth two rows arrange, and the position of the first breach d1 is located at the outside of the rectangle of 6 spray silk micropores, 221 formation.
