Abstract
The utility model provides a spinneret plate for producing hollow fibers. The spinneret plate is characterized by consisting of 12 to 144 spinneret orifices with the same structure; each spinneret orifice is C-shaped; a C-shaped opening points to the center of the spinneret plate; the upper and lower parts of the C shape of each C-shaped spinneret orifice are symmetrical, and the C shape is formed by sequentially connecting six small circles; and the circle centers of the six small circles are positioned on the same circle of which the diameter is 0.46mm. The spinneret plate is high in processing accuracy, can keep high spinnability and is widely applied to manufacturing of various products such as clothing, quilt wadding, pillows without pillow cases, cold-proof articles and the like; and by using the spinneret plate, the fibers are hollow, and the sections of the fibers have special shapes, and the fibers have the characteristics of high glossiness, and heat preservation and the like and are fluffy.
Description
Technical field
The present invention relates to a kind of synthetic fiber and produce accessory, specifically is a kind of spinnerets of producing doughnut.
Background technology
Cross sectional shape that the general fibre cross section is rounded, solid and structure lack good suction, moisture pick-up properties, and regain is merely 0.4%; About fracture strength 5.0CN/dtex, extension at break 20-30%, initial modulus reaches 1.10cN/dtex; Demonstrate the wet comfortableness of relatively poor heat; In high humidity, the condition of high temperature, can make the people that feeling of oppression and heat is arranged by this twice-laid clothes, mood is had the fidgets; Lack good sense of touch comfortableness, skin-friendly is relatively poor.
Natural fabrics such as general kapok, wool, eider down have cavity, and the spy is kapok fully, and degree of hollowness is up to 70%.Manufacturing has emulation mode with the doughnut in the close cross section of natural fabric by extensive employing.This is because odd-shaped cross section makes appearance profile be irregular, makes polyester textile that fluffy sense arranged, and has improved gloss effect and feel, has improved fabric breathability, PILLING RESISTANCE.Hollow structure has reduced quality of fiber, has improved the heat-insulation warm keeping property of fabric.Compare with single round doughnut, profiled filament and to have more superiority; Fabric with this fiber making; Its bulkiness is than the big 15-20% of common fabric; And anti-wear performance is higher 2 times than common circular fiber, with doughnut as material can make clothes, by multiple products such as wadding, pillow, winter protection articles, very popular.
Summary of the invention
The utility model purpose provides a kind of spinnerets of producing doughnut, and machining accuracy is high, and good spinnability is used to produce doughnut, good product quality, added value height, and production cost is low.
A kind of spinnerets of producing doughnut is characterized in that it being to be made up of 12～144 identical spinneret orifices of structure, and spinneret orifice is " C " font, and the opening of " C " font points to the spinnerets center.
Described " C " shape spinneret orifice is characterized in that " C " font is up and down symmetrical, is to be connected successively each other by 6 small circular, and the center of circle of 6 small circular is on the circle of 0.46mm at same diameter.
Described small circular is characterized in that first small circular diameter of " C " font head end is 0.13mm, and second and third that connects successively, four, five, six small circular diameters are respectively 0.13mm, 0.11mm, 0.11mm, 0.13mm, 0.13mm; The width that each small circular connects is 0.065mm; The vertical range in first small circular center of circle and second small circular center of circle is 0.25mm; The vertical range in second the small circular center of circle and the 3rd the small circular center of circle is 0.21mm; Distance between the 3rd small circular center of circle and the 4th the small circular center of circle is 0.21mm; The vertical range in the 4th the small circular center of circle and the 5th the small circular center of circle is 0.21mm, and the 5th the small circular center of circle and the 6th small circular center of circle vertical range are 0.25mm, and the distance in the 6th the small circular center of circle and first small circular center of circle is 0.29mm.
The progressive effect of the utility model is: machining accuracy is high; The fiber that uses the utility model to produce; Keeping better spinnability simultaneously, make fibrous inside have hollow, the cross section is abnormity; Have characteristics such as glossiness is good, fluffy insulation, be widely used in and make clothes, by multiple products such as wadding, pillow, winter protection articles.
Description of drawings
Fig. 1 is the utility model spinneret face; Fig. 2 is the spinneret pore structure sketch map of the utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is at length explained.
In the practical implementation process, polyester fondant is through the spinning of the utility model spinnerets, because the polyester fondant bulking effect, the cross section of a rhizoid of extruding through " C " font spinneret orifice of spinnerets forms a closed round ring, produces doughnut.
The spinnerets machining accuracy of the utility model is high, good spinnability, and the doughnut degree of hollowness that uses the utility model to produce is high, can reach more than 60%.With the fabric that this fiber is made, its bulkiness is than the big 10-20% of common fabric, and the common circular fiber of weight ratio is light by 50%, with doughnut as material can make clothes, by multiple products such as wadding, pillow, winter protection articles, very popular.
