Abstract
The invention discloses spinneret plate holes for producing sixteen-hole hollow fiber. The spinneret plate holes for producing the sixteen-hole hollow fiber are formed by arranging circular-arc-shaped gaps equal in diameter, wherein the circular-arc-shaped gaps are not communicated mutually. In an inner layer, two circular-arc-shaped gaps are reverse in openings and are arranged in an axial symmetry mode, and a separation distance is reserved between the two circular-arc-shaped gaps. In an outer layer, twelve circular-arc-shaped gaps with the two circular-arc-shaped gaps formed in the inner layer as the center are distributed circumferentially and evenly, and the openings of the circular-arc-shaped gaps are formed in clockwise direction or anticlockwise direction. The spinneret plate holes for producing the sixteen-hole hollow fiber have the advantages that the spinneret plate holes are high in structural accuracy, fluffed closing can be ensured under the normal process conditions, and sixteen-hole hollow fiber with good spinnability are produced, has good advantages of good glossiness, moisture and sweat absorption, fluffing, warm keeping and the like and meets the production demand for high-quality fabrics.
Description
Technical field
The present invention relates to a kind of spinnerets of textile industry, particularly a kind of spinneret hole producing doughnut.
Background technology
Doughnut has that bulkiness is high, good springiness, warmth retention property are strong, soft smooth, the feature such as resilience good, spreadability is good, is widely used in the numerous areas such as gum sprayed cotton, imitative plumage cotton, bedding, insulated cold wear, toy, fabric.
Current doughnut mostly on the market is seven apertures in the human head, nine hole doughnuts, its know-why of producing utilizes Barus effect, namely there is viscoelastic high polymer molten, when flowing out the spinneret orifice mouth of spinnerets, there is fluid because of the elastomeric deformable energy stored during melt stream release entrance and expanding effect.Concrete enforcement is exactly by several discontinuous straight line or curvilinear slits composite design together, form the spinneret orifice of a special shape, make to swell effect and being normally sticked together because there is ballas before curing from these high polymer moltens of extruding of combination slit, melt just obtains through cooling curing the doughnut that inside is surrounded by one or several continuous cavity thus.
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide the spinneret hole of a kind of production 16 hole doughnuts, and its fiber produced meets the Production requirement of high-grade fabric.
Technical scheme: the spinneret hole of a kind of production 16 hole doughnut, the circular arc slit arrangement identical by diameter is formed, all circular arc slits are not communicated with mutually: to be that two circular arc slit openings are opposing arrange internal layer axisymmetricly, and have spacing between two circular arc slits; Skin is that 12 circular arc slits are circumferentially uniform centered by two of internal layer circular arc slits, and the opening of circular arc slit all in the direction of the clock or counterclockwise.
Two circular arc slits of internal layer are semicircle, and outer field 12 circular arc slits are slightly larger than semicircular major arc.
Described spacing is between 0.04 ~ 0.2mm.
Beneficial effect: compared with prior art, advantage of the present invention is that structure precision is high, can ensure expanded closed under normal process conditions, produce the 16 hole doughnuts with good spinnability, there is the characteristics such as good glossiness, moisture absorbing and sweat releasing, fluffy insulation, meet the Production requirement of high-grade fabric.
Accompanying drawing explanation
Accompanying drawing is structural front view of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in drawings, the spinneret hole of a kind of production 16 hole doughnuts, with the identical circular arc slit 1 of diameter for elementary cell, form by inside and outside two-layer arrangement, be not communicated with mutually between all circular arc slits: to be that two circular arc slit openings are opposing arrange internal layer axisymmetricly, and between two circular arc slits, there is spacing δ, form four hollow holes; Skin is that 12 circular arc slits are circumferentially uniform centered by two of internal layer circular arc slits, and the opening of circular arc slit all in the direction of the clock or counterclockwise.Two circular arc slits of internal layer are semicircle, and outer field 12 circular arc slits are slightly larger than semicircular major arc.
When carrying out the design of many hollow spinneret plates hole, the size of spacing δ value is a key parameter.δ value is too small, and because Swelling Functions not easily forms hollow, and affect the intensity of spinnerets, δ value is excessive, and expanded ratio does not reach, thus melt can not adhesion, forms sub-wire.Rule of thumb sum up, δ value, between 0.04 ~ 0.2mm, can ensure expanded closed under normal spinning process condition.
