Description
Technical Field
The utility model relates to the technical field of filament manufacturing, in particular to a five-hole hollow polyester filament and a spinneret plate for preparing the same.
Background
Polyester filament is the most used synthetic filament in the field of clothing industry at present, and is favored by the majority of users due to excellent physical and chemical properties. With the development of science and technology and the improvement of the living standard of people, the requirements of people on the comfort and the functionality of textiles are gradually improved. The hollow polyester has the characteristics of heat preservation, light weight, fluffiness and the like, so that the hollow polyester is more and more concerned by researchers and loved by consumers.
The hollow polyester is a special-shaped polyester filament yarn and is characterized in that the cross section of the hollow polyester filament yarn has a cavity structure along the axial direction. The cavity structure has the function of storing static air, so that the warmth retention property and the moisture absorption and sweat releasing functions of the filament are improved, but the warmth retention property and the moisture absorption and sweat releasing functions of the polyester filament of the single cavity pipeline are limited, and the requirements of users cannot be met. Therefore, the technical difficulty to be solved at present is to improve the heat insulating property, moisture absorption and sweat releasing property of the hollow polyester filament yarn with a multi-cavity structure on the basis of not influencing the spinnability of the polyester filament yarn.
SUMMERY OF THE UTILITY MODEL
The utility model provides a five-hole hollow polyester filament and a spinneret plate for preparing the same in order to solve the technical defects.
The utility model discloses a five-hole hollow polyester filament yarn which comprises a filament yarn body, wherein four first through holes are annularly arranged on the periphery of the cross section of the filament yarn body, and a second through hole is formed in the middle of the four first through holes.
The first through holes are all circular, and the second through holes are non-circular.
Above-mentioned scheme, because the filament body is inside to be porous cavity form, a plurality of cavity structures make the filament have good cold-proof effect, and when the filament body contacted the sweat simultaneously, the many cavity structures were changeed and were made the sweat enter into inside the filament body to the poor problem of moisture absorption sweat releasing performance of polyester filament has been improved, and porous hollow structure further increases the fluffy sense of polyester filament.
The spinneret plate for preparing the five-hole hollow polyester filament comprises a spinneret plate body and spinneret holes arranged on the spinneret plate body, wherein the spinneret holes are in the shapes of: the four groups of semicircular holes are uniformly arranged at intervals on the same circumference; each group of semicircular ring holes are provided with two semicircular ring holes, the openings of the two semicircular ring holes are opposite, and the two semicircular ring holes of each group are spaced from each other.
The inner diameter of each of the four groups of semicircular holes is 0.225mm, the outer diameter of each of the four groups of semicircular holes is 0.29mm, and the distance between two semicircular holes in the same group is 0.08 +/-0.01 mm; the centers of the four groups of semicircular ring-shaped holes are positioned at four corners of a square, and the distance between the centers of the two groups of semicircular ring-shaped holes at opposite angles is 0.96 mm.
According to the scheme, each spinneret orifice is formed by combining eight semicircular ring-shaped holes, the eight semicircular ring-shaped holes are divided into four groups, two semicircular ring-shaped hole openings of each group are arranged in a mirror image mode, and the distance between the semicircular ring-shaped holes is reasonably controlled. Actual polyester melt extrusion process principle: the melt after the polyester melt is extruded through the two mirror image semicircular ring-shaped holes expands to ensure that the edges of two beams of arc-shaped melt can be bonded to form a hollow filament, and the number of mirror image semicircular ring-shaped group holes is increased, so that a new monofilament spinneret hole is formed; designing a four-hole structure in cross arrangement, adjusting the distance between four groups of mirror image semicircular ring holes to minimize the influence of adjacent hollow melts on respective hole patterns, extruding and expanding four beams of hollow melts simultaneously to create a new hollow structure in the middle, and finally forming the five-hole hollow monofilament section shown in the figure 1, wherein four peripheral holes are circular, and a central cavity is polygonal or irregular.
The number of the spinneret orifices on the spinneret plate can be set according to actual requirements.
Compared with the prior art, the five-hole hollow polyester filament yarn and the spinneret plate for preparing the same have the following gain effects:
1. the interior of the filament body is hollow with five holes, and a plurality of cavity structures store more static air, so that the polyester filament has good heat preservation effect;
2. when the polyester filament with the five-hole hollow structure is contacted with sweat, the sweat can easily enter the filament body, so that the problem of poor moisture absorption and sweat releasing performance of the polyester filament is solved, and meanwhile, the bulkiness of the polyester filament is further improved due to the multi-cavity structure;
3. the monofilament spinneret orifices are arranged in a cross manner by adopting four groups of mirror image semicircular annular orifices, the melt is extruded and expanded through the four groups of mirror image semicircular orifices to form four beams of hollow melt, and because a certain distance exists between the four beams of melt, the adjacent hollow melt is bonded, and meanwhile, a cavity is formed in the middle of the four beams of melt, so that the polyester monofilament with a five-hole structure is prepared. The filament can be applied to household clothes, leisure sports clothes, bedding and outdoor sports clothes.
