Description
Technical Field
The invention relates to a spinning assembly, in particular to a composite spinning assembly, particularly relates to a composite spinning assembly for producing superfine fiber mixed filaments, and belongs to the technical field of synthetic fiber production.
Background
At present, spinning assemblies for producing fine denier filaments are of three types, one type is to produce a single-component spinning assembly (the shape of a spinneret orifice is circular or special-shaped), fibers spun by the assembly only contain one polymer, the filament number of the fibers is larger and generally larger than 0.55dtex, and the fibers cannot be applied to fabrics such as superfine suede fabrics, clean fabrics, quick-drying towels and the like.
The other is a composite spinning pack for producing a composite fiber, which can produce a splittable or sea-island type composite fiber, which is split or dissolved by a chemical or mechanical method in a post-treatment process to obtain a superfine fiber having a fine and uniform single fineness, generally 0.22dtex or less. The fiber is mainly used in fabrics such as micro-fleece fabrics, clean fabrics, quick-drying towels and the like, because the filament number is thin, the manufactured fabrics have poor body and soft hand feeling, and if the fabrics with soft hand feeling and strong body are to be obtained, the fiber needs to be twisted with thicker monofilament fibers (such as high-shrinkage fibers) in the subsequent processing process to produce mixed filaments, so that the differential shrinkage effect is formed, the hand feeling and the style of the fabrics are improved, the fiber production process is invisibly increased, and the manufacturing cost is increased.
The third is a spinning assembly for producing mixed filament yarn, the size and shape of the pore diameter of the spinneret orifice on the assembly are different, and the fiber produced by the assembly has different titer, different section and different shrinkage effects. The disadvantage is that the module cannot produce superfine mixed filament yarn, the finest filament fineness is usually more than 0.55dtex, and although the effect of raising is achieved in the post-treatment, the hand feeling of the produced fabric is inferior to that of superfine fiber.
Therefore, in the existing three spinning assemblies, the fiber produced by the single-component assembly cannot be used for producing superfine fiber; the mixed fiber component can only be used for producing mixed fiber with filament number more than 0.55dtex, and can not produce superfine mixed fiber, and the softness of the fabric can not meet the requirements of the subsequent users; the superfine fibers produced by the composite spinning assembly have very thin monofilament fineness, but the fabric has poor skeleton and cannot be directly used for weaving, and the superfine fibers and thick monofilaments are subjected to secondary stranding processing to prepare mixed filaments so as to meet the requirements of subsequent users, so that the working procedures and equipment are increased invisibly, the investment is increased, and the energy consumption is increased.

Detailed Description
As shown in figure 1, the main structure of the invention is similar to other two-component composite spinning components, and is suitable for composite spinning of two different components in a molten state, the component is integrally surrounded by an upper shell and a lower shell, two melt channels which are not communicated with each other are arranged in the upper shell, inlets 1 and 2 for two polymer melts to be subjected to melt spinning are provided, an upper cover plate 4, a filter screen 5, an upper distribution plate 6, a lower distribution plate 7, a composite plate 8 and a spinneret plate 9 are sequentially arranged in the lower shell 3 along the melt flowing direction, and after the two different polymer melts enter the component from the upper shell, the two different polymer melts are respectively filtered and distributed through the upper cover plate 4, the filter screen 5, the upper distribution plate 6 and the lower distribution plate 7 and are communicated with corresponding interfaces on the upper side of the composite plate 8 from. And a plurality of bosses are arranged at the lower ends of the alternate or adjacent grooves with downward openings on the lower side of the composite plate 8 and correspond to the positions of the spinneret orifices on the spinneret plate 9 below the composite plate 8. When the component works, two polymer melts flow into the spinneret plate 9 from the inner channel of the boss at the lower side of the composite plate 8, and the composite spinning process is completed under the action of the spinneret holes.
The invention is characterized in that, among all the bosses on the lower side of the composite plate 8, the inner part of one part of the bosses is provided with a channel which can lead two different melts to flow through smoothly, and the inner part of the other part of the bosses is only provided with a channel which can lead one melt to flow through smoothly. The technical means for realizing the scheme can be realized in two ways: one is to select part of bosses of the inner ring or the secondary inner ring at the lower side of the composite plate 8, and directly process the bosses into single-hole or multi-hole channels through which only the same melt flows, fibers extruded from spinneret holes below the part of bosses are single-component fibers, other parts of bosses of the inner ring and the secondary inner ring of the composite plate and all bosses of the outer ring are designed into composite type, and the fibers extruded from the spinneret holes below the bosses are still composite fibers during spinning; alternatively, all bosses may be provided with two different melt channels in their interiors, but a metal ring may be added around a portion of the bosses to enclose one of the melt channels in the interior of that portion of the boss, so that the melt cannot flow from the composite plate 8 to the spinneret 9. The two modes can ensure that the composite spinning assembly forms composite mixed filament yarns compounded by single-component fibers and composite fibers in different proportions in the spinning process, the single-component part of the composite mixed filament yarns can be round or other profiled fibers or hollow fibers, and the composite fiber part can be sea-island type, split type, double-component composite fibers or other composite fibers.
The latter scheme can be illustrated with figures 2 and 3: the boss is provided with two polymer melt channels 10 and 11 inside, and a metal ring 12 is provided around the boss, which metal ring 13 closes one of the melt channels 10 so that the melt flowing from the lower distribution plate 7 cannot flow through this channel into the spinneret 9. Thus, the fibers formed through the orifices below the boss are monocomponent fibers. As only part of the bosses are provided with the metal rings which play a role in flow resistance, the composite mixed filament yarn which consists of single-component fiber and composite superfine fiber can be spun by using the same spinneret plate from the view point of the whole assembly.
When the latter technical scheme is applied, the bosses are closed by the metal rings at the end, and the bosses can be randomly selected or regularly selected according to the distribution condition of the bosses on the composite plate. The proportion of the monocomponent fibers in the composite multifilament yarn can be changed by adjusting the number of bosses isolated by the metal rings. Usually, the bosses are annularly distributed on the lower side of the composite plate, and a simple method for applying the technical scheme of the invention comprises the following steps: a closed detachable metal ring is selectively added on the outer ring of the boss of the inner ring or the secondary inner ring, and the flow line of two spinning melts is limited, so that the two melts are compounded on only one part of the boss and cannot be compounded on the other part of the boss which is separated. The fiber extruded from the spinneret holes below the bosses which can not be compounded is single-component fiber, and the fiber extruded from the spinneret holes below the bosses without adding the metal rings is the compound superfine fiber with the shape set by the bosses.
From the perspective of technical improvement, the technical scheme of adding the metal ring has stronger popularization and use values. Furthermore, the metal ring can be designed into a detachable assembly structure, and when the composite combined filament yarn needs to be produced, the metal ring is arranged at the lower side of the composite plate; when the bi-component composite fiber is required to be produced completely, the metal ring can be removed at any time. Therefore, the product brands of the same production line can be conveniently switched. In addition, the hole shape of the spinneret hole of the spinneret plate below the boss of the metal ring is increased, and the hole shape can also be designed into a circular shape, a special shape or a hollow shape, so that the cross section shape of the monocomponent fiber in the spun composite combined filament yarn is circular shape, special shape or hollow shape, and the function of the composite combined filament yarn is further increased.
In addition, as will be appreciated by those skilled in the art, the bosses on the underside of the composite plate may be either integral or detachable, and the shape of the bosses may be different structures, such as a peel-off type, a sea-island type, or other different composite types.
The following are two specific examples completed by the applicant, by which the technical solution of the present invention can be further understood.
