Abstract
The invention provides a spinneret plate used for six-petaloid regeneration hollow polyester staple fibers, and belongs to the technical field of polyester fiber preparation. The spinneret plate comprises a spinneret plate main body and a plurality of spinneret micropores arranged on the spinneret plate main body. The spinneret plate is characterized in that the spinneret micropores are distributed on the spinneret plate main body in a plurality of circles of concentric circles, each spinneret micropore is in a six-petaloid hollow structure formed by an inner contour line and an outer contour line, and the outer contour line is formed by connecting six semicircles whose radiuses are the same from the head to the tail in sequence, and the inner contour line is round. The cross section of a regeneration polyester staple fiber manufactured by the spinneret plate used for six-petaloid regeneration hollow polyester staple fibers is in a six-petaloid hollow shape, and the fiber is characterized by good heat retention property, excellent crimp property, good glossiness, moisture absorption and sweat releasing, excellent fluffy thermal insulation properties. The regeneration polyester staple fiber can be widely applied in fields of casual clothes, thermal underwear, winter down jackets, shirts, sports series, and other high-fashion clothing.
Description
Technical field
The present invention relates to the spinneret that a kind of six lobe regeneration hollow polyester chopped fiber produce, belong to technical field of polyester fiber preparation.
Background technology
In recent years, fast-developing with the chemical fibre industry that polyester is representative, bringing huge facility to human being's production and life, but all kinds of waste polyester textile pollution on the environment is also day by day serious. Regenerated Polyester Fibres industry is by the production of waste and old polyester plastics material, processing and utilization, and the social benefit of generation is much larger than the economic benefit of enterprise. Both having added the effective supply of national product by producing regenerative polyester staple fiber with the useless bottle sheet of polyester, the development of Regenerated Polyester Fibres industry simultaneously directly facilitates again and has promoted related industry development.
Special hollow fibre technology has important using value in the exploitation of Regenerated Polyester Fibres. Initial recycled polyester hollow core staple fibers, every fiber only has single hole, and the hole shape of use is the spinneret of C type, double; two semi-circular, three-arc type. Single hole hollow core staple fibers is when spinning thick denier yarn, and degree of hollowness is about 15%, it is difficult to obtain good resilience, and fibrous external configuration of surface is dull, and excessively thick single hole silk can be crushed deformation; The spinneret of invention Porous hollow type later, main purpose is to improve degree of hollowness and the elasticity etc. of coarse denier fiber, and the main application fields of this fibrid is inserts class.
Spinneret is to manufacture six lobe hollow spinneret plates to produce the critical component of regenerative polyester staple fiber, owing to this spinneret manufacturing technology is complicated, it is desirable to precision is high, highly polished, can therefore mask-making technology difficulty be relatively big, and especially whether hole type design is reasonable, be the key that obtain expection fibre section. In addition, six lobe hollow rejuvenation polyester staple fiber spinning techniques require strict, and its fiber shape is wayward, and easily produce lousiness and broken end in spinning process, thus, so far there are no the report of the spinneret of six lobe hollow rejuvenation polyester staple fibers productions and chopped fiber thereof.
Summary of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, it is provided that a kind of six lobe regeneration hollow polyester chopped fiber spinnerets, be used for producing six lobe regeneration hollow polyester chopped fiber.
The present invention is achieved by the following technical solutions: a kind of six lobe regeneration hollow polyester chopped fiber spinnerets, including spinneret main body and the multiple spinneret orifices being arranged in spinneret main body, it is characterized in that, described spinneret orifice is that some circle concentric arrays are distributed in spinneret main body, each spinneret orifice is the six lobe hollow structures being made up of inner outline and outer contour, described outer contour is that the semi arch head and the tail that six radiuses are equal are sequentially connected composition, and described inner outline be circle.
The radius of described semi arch is 0.1-0.3mm.
The circular radius of described inner outline is 0.05-0.15mm.
The described concentrically ringed number of turns is 3-8 circle.
The spinneret that six lobe regeneration hollow polyester chopped fiber provided by the invention produce, the cross section of the regenerative polyester staple fiber produced is six lobe hollow shapes, there is the characteristics such as thermal property is good, crimp property is excellent, glossiness good, moisture absorbing and sweat releasing, fluffy insulation function admirable, can be widely used for easy suit, cold-proof underwear, winter down jackets, vest, the high-grade garment industry such as Sports Series.
Accompanying drawing explanation
Figure l is the schematic cross-section of the six lobe regeneration hollow polyester chopped fiber that the present invention prepares;
Fig. 2 is the structural representation of spinneret orifice in the present invention;
Fig. 3 is the structural representation of the present invention;
In figure: 1 spinneret main body, 2 spinneret orifices, 3 semi arches, 4 circles.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is expanded on further.
Embodiment one
As it is shown on figure 3, the present invention is a kind of six lobe regeneration hollow polyester chopped fiber spinnerets, spinneret includes spinneret main body 1 and the multiple spinneret orifices 2 being arranged in spinneret main body 1. Wherein, spinneret orifice 2 is distributed in spinneret main body in concentric arrays, and the arrangement number of turns is 4 circles; As in figure 2 it is shown, each spinneret orifice is the six lobe hollow structures being made up of inner outline and outer contour, outer contour is that semi arch 3 head and the tail that six radiuses are equal are sequentially connected composition, and inner outline be circle 4. The radius R of six semi arches is 0.18mm, and the circular radius r of middle inner outline is 0.08mm.
Embodiment two
A kind of six lobe regeneration hollow polyester chopped fiber spinnerets, the spinneret orifice 2 in spinneret main body 1 is in concentric arrays, and the arrangement number of turns is 6 circles; Each spinneret orifice is the six lobe hollow structures being made up of inner outline and outer contour, and outer contour is that semi arch 3 head and the tail that six radiuses are equal are sequentially connected composition, and inner outline be circle 4. The radius R of six semi arches is 0.2mm, and the circular radius r of middle inner outline is 0.10mm.
Adopt the regeneration hollow polyester chopped fiber that above-mentioned spinneret prepares, its cross section is six lobe hollows, have that glossiness is good, moisture absorbing and sweat releasing, fluffy insulation function admirable and the stable feature of spinning process, can be widely used for the high-grade garment industry such as easy suit, underwear, vest, Sports Series.
The above, it it is only presently preferred embodiments of the present invention, not the technical scope of the present invention is imposed any restrictions, therefore every any trickle amendment, equivalent variations and modification above example made according to the technical spirit of the present invention, all still fall within the scope of technical solution of the present invention.
