Abstract
The utility model discloses a spinneret plate hole for producing a nineteen-hole hollow fiber. A symmetrical honeycomb structure is formed by nineteen regular hexagon units with adjacent sides shared, each regular hexagon unit is composed of six narrow gaps, the two ends of each narrow gap are 120-degree isosceles sharp corners, and the distances between every two adjacent narrow gaps are equal. The spinneret plate hole for producing the nineteen-hole hollow fiber has the advantages of being high in structural precision, can guarantee expansion closure under the condition of normal technology, and can produce the nineteen-hole hollow fiber with good spinnability, wherein the nineteen-hole hollow fiber is good in glossiness, hygroscopic, sweat releasing and fluffy, keeps warm and can meet the demands for producing high-grade shell fabric.
Description
Technical field
The utility model relates to a kind of spinnerets of textile industry, particularly a kind of spinneret hole of producing doughnut.
Background technology
Doughnut has strong, soft smooth, the characteristics such as resilience good, spreadability is good of bulkiness height, good springiness, warmth retention property, is widely used in the numerous areas such as gum sprayed cotton, imitative plumage cotton, bedding, insulated cold wear, toy, fabric.
Present doughnut on the market mostly is seven apertures in the human head, nine hole doughnuts, the know-why of its production is to utilize Barus effect, namely has viscoelastic high polymer molten, when flowing out the spinneret orifice mouth of spinnerets, fluid occurs and expands effect in the distortion elastic energy of storing when discharging entrance because of the melt thread.Implementation is combined several discontinuous straight lines or curve slit designs exactly, form the spinneret orifice of a special shape, so that swell effect and normally be sticked together solidifying cause generation ballas from these high polymer moltens of extruding of combination slits, melt has just obtained the inner doughnut that is surrounded by or several continuous cavitys through cooling curing thus.
The utility model content
The utility model purpose: for the problems referred to above, the purpose of this utility model provides a kind of spinneret hole of production 19 hole doughnuts, and the fiber of its production satisfies the Production requirement of high-grade fabric.
Technical scheme: a kind of spinneret hole of production 19 hole doughnuts, become symmetrical honeycomb by nineteen regular hexagon unit adjacent side common group, each described regular hexagon unit is made of six slits, every described slit two ends are 120 ° of isosceles wedge angles, and pitch spacing is all arranged between the adjacent described slit etc.
Described spacing is between 0.04～0.2mm, and is best, and described spacing is between 0.08～0.12mm.
Beneficial effect: compared with prior art, the utility model has the advantages that structure precision is high, under normal process conditions, can guarantee expanded closure, produce 19 hole doughnuts with good spinnability, have the characteristics such as good glossiness, moisture absorbing and sweat releasing, fluffy insulation, satisfy the Production requirement of high-grade fabric.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is regular hexagon cellular construction front view among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
Shown in accompanying drawing 1,2, a kind of spinneret hole of production 19 hole doughnuts, become symmetrical honeycomb by nineteen regular hexagon unit adjacent side common group, satisfy Central Symmetry and axial symmetry, each regular hexagon unit is made of six slits 1, every slit 1 two ends are 120 ° of isosceles wedge angles 2, and every slit 1 its opposite side is parallel, and pitch spacing ε is all arranged between the adjacent slots 1 etc.
When carrying out the design of many hollow spinneret plates hole, the size of spacing ε value is a key parameter.The ε value is too small, because Swelling Functions be difficult for to form hollow, and affect the intensity of spinnerets, the ε value is excessive, and expanded ratio does not reach, thereby melt can not adhesion, the formation sub-wire.Rule of thumb sum up, the ε value can guarantee expanded closure under normal spinning process condition between 0.04～0.2mm, and its optimum value is between 0.08～0.12mm.
