The beneficial effects of the utility model are that, the utility model discloses a fibre that the spinneret produced, its cross section are cavity runway shape, and this spinneret processing is simple and convenient, the cost of manufacture is low, long service life, and the cavity runway type fibre that makes has that thermal insulation performance is good, resilience and moisture absorption rate are high, crimping excellent performance, not only makes the fibre have fine resilience, moreover because hollow wicking action, still gives fine heat preservation of fibre and moisture absorption sweat releasing ability.
Description
Technical Field
The utility model relates to a spinneret technical field, especially a preparation hollow runway type polyester staple fiber's spinneret.
Background
Most of conventional chemical fibers have circular cross sections and have certain limitation in the application of moisture absorption and heat retention, and hollow polyester fibers have unique advantages in the aspects of filtering performance, heat retention performance and moisture conductivity compared with conventional polyester fibers with circular cross sections as typical differentiated polyester fiber varieties; the hollowness and the mechanical property of the hollow round polyester yarn can be adjusted and controlled manually through the spinning temperature, the cooling forming and the subsequent heat setting process, and the production process is relatively mature, but the hollowness and the heat retention of the hollow round polyester yarn cannot meet the current requirements.
In view of the above, there is a need to improve the shape of the existing spinneret holes to meet the demands of hollowness and heat retention of the polyester yarn.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the present circular dacron silk of present cavity degree of hollowness, heat preservation can not satisfy present needs, consequently designed a spinneret orifice and be the spinneret of hollow runway type, specifically be a spinneret of preparation hollow runway type dacron short-staple.
The technical scheme of the utility model be, a preparation hollow runway type polyester staple fiber's spinneret, including spinneret main part and a plurality of unevenly distributed spinneret orifices of setting in the spinneret main part, the spinneret orifice comprises two semicircular arc holes and sharp connection, U type hole is constituteed with sharp connection to two semicircular arc holes, the spinneret orifice is two U type hole intervals just to setting up, and has the clearance between the adjacent spinneret orifice.
Further supplementing the scheme, the spinneret plate main body is provided with 3-10 layers, so that cooling air can penetrate through strand silk to realize rapid cooling.
Further supplementing the scheme, the spinneret plate body is circular.
In addition to the scheme, the spinneret plate main body is in a circular ring shape, and the middle annular part is the position of ring cooling air blowing.
Further supplementing the scheme, the number of the spinneret orifices is 100-300.
And the scheme is further supplemented, and the tail end of the linear part on the spinneret orifice is set to be in a circular arc shape.
Its beneficial effects lie in, the utility model discloses a fibre that the spinneret produced, its cross section are cavity runway shape, and this spinneret processing is simple and convenient, the cost of manufacture is low, long service life, and the cavity runway type fibre that makes has that thermal insulation performance is good, resilience and moisture absorption rate are high, crimping performance is good, not only makes the fibre have fine resilience, moreover because hollow wicking action, still gives fine heat preservation of fibre and moisture absorption and perspiration ability.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the arrangement of the spinneret orifices of FIG. 1;
in the figure, 1, a spinneret body; 2. and (4) spinneret orifices.
Detailed Description
First explain the utility model discloses a design is original intention, because present circular polyester filament of cavity wherein hollowness, heat retention can not satisfy present needs, in order to improve its present market of laminating more of hollowness, heat retention of polyester filament, the utility model provides a spinneret of preparation hollow runway type polyester staple fiber to replace the circular polyester filament of current cavity, improve the hollowness, heat retention, the wet guide of polyester filament.
In order to make the technical solution more clear to those skilled in the art, the following will explain the detailed structure and principle of the above mechanisms with reference to fig. 1-2: a spinneret plate for preparing hollow runner type polyester staple fibers comprises a spinneret plate main body 1 and a plurality of spinneret holes 2 which are arranged on the spinneret plate main body 1 and are not uniformly distributed, wherein each spinneret hole 2 is formed by connecting double semicircular arc holes and straight lines, the double semicircular arc holes and the straight lines form U-shaped holes, the spinneret holes 2 are formed by oppositely arranging two U-shaped holes at intervals, and gaps exist between the adjacent spinneret holes 2; the spinneret plate main body 1 is provided with 3-10 layers, so that cooling air can penetrate through strand silk to realize rapid cooling; wherein the spinneret plate body 1 is circular; the number of the spinneret holes 2 is 100-300.
In addition to the above structure, another structure is provided below, the spinneret plate main body 1 is in a ring shape, and the middle ring part is a position for cooling and blowing the ring; and the tail end of the straight line part on the spinneret orifice 2 is set to be circular arc.
Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
