Abstract
The utility model relates to a terylen short fiber spinneret plate with a fine denier equiangular triangular cross section. The original equiangular triangular spinneret hole shape is changed, a distorted equiangular triangular star shape is adopted, three acute angles are changed into three identical rounded angles, three edges are changed into three circular arc lines depressed inwards to the circle center, therefore, the three circular arc lines are smoothly connected into a distorted triangular star shape, thereby the cross section of the terylen short fiber spun by spinneret plate hole presents an equiangular triangular star shape, the shining effect is good, and the defaults that the formed fiber cross section of the original spinneret plate does not present an equiangular triangular shape because the melting body has expanding effect during the silking process, and the refraction rate is not ideal are changed.
Description
1. technical field
The utility model relates to the synthetic fiber production field in textile industry and the petrochemical industry, relates to the production equipment of polyester staple fiber.
2. background technology
Current fiber with flash effect becomes the focus of piece market, equilateral triangle cross section polyester staple fiber of thin dawn by Shanghai the tenth chemical fibre factory's Development and Production is a kind of novel short fiber material, but because of the spinnerets hole shape adopts the equilateral triangle shape, the terylene melt has bulking effect in spinning process, the fibre section, back does not form an equilateral triangle so be shaped, so the refractive power effect of fiber is subjected to very big influence, product quality and effect are not ideal enough.
3. summary of the invention
The purpose of this utility model is on the basis through constantly experiment, designs a kind of irregularly-shaped hole spinnerets, the product that produces through supporting spinning and draft process, and its cross section has equilateral triangle, light is reflected and is flash effect preferably.
The expanded effect of design consideration polyester staple fiber melt of the present utility model, the equilateral triangle hole shape of spinnerets is designed to a kind of positive tri-star shape of distortion, the feature that keeps original equilateral triangle, promptly equate from triangle center point to distance between each top, angle, and three acute angles of equilateral triangle are made into three equal fillets, three limits of equilateral triangle, make into to three of the center indent equal circular arc lines by straight line, smoothly thus connect into a tri-star shape.Because fine denier polyester staple fibre fineness is generally 1.67dtex to 2.22dtex, so the distance from triangle star center to each fillet top is 0.25～0.35mm, the radius of three fillets is R0.03～0.06mm, and the radius of three circular arc lines is in R0.3～0.5mm scope.
The polyester staple fiber that the utility model has the advantages that spinnerets hole shape production is thus made fabric through textile mills' spinning and is seen, because its cross section has the equilateral triangle shape, institute is so that light refraction is effective, and flash effect is very good, adheres to specification.
4. description of drawings
Accompanying drawing is the shape schematic diagram of spinnerets hole shape described in the utility model.
5. the specific embodiment
Below be an embodiment.
When producing the 1.67dtex polyester staple fiber, the concrete size of its spinnerets hole shape is as follows:
The distance on triangle star center to fillet summit is 0.35mm.
The radius of three fillets is R0.055mm.
Article three, the radius of circular arc line is R0.4mm.
The spinnerets process technology is a prior art.
Adopt when the light section is arranged greatly, the technological process of production is:
Drying → spinning → coiling → shaping → boundling → drawing-off → curl → setting → cut-out.
Spinning on VD406 type spinning machine, pump is 500g/min for amount, winding speed 1000m/min, 285 ℃ of spinning temperatures, spinnerets adopt 720 holes.On the LVD801 drawing machine, carry out drawing-off, 3.6 times of drafting multiples, 100 ℃ of drawing temperatures, three times setting temperature is respectively 110 ℃, 105 ℃, 120 ℃.
Claims (2)
1. thin dawn equilateral triangle polyester staple fiber spinnerets, it is characterized in that described spinnerets spinneret orifice shape is a kind of positive tri-star shape of distortion, distance from triangle star central point to each top, angle equates, three angles of triangle star are three equal fillets, three limits of triangle star are to three of the center indent equal circular arc lines, smoothly thus connect into a tri-star shape.
2. spinnerets as claimed in claim 1 is characterized in that the distance of pushing up to each fillet from triangle star center is 0.25～0.35mm, and the radius of fillet is 0.03～0.06mm, and the radius of circular arc line is 0.3～0.5mm.
