Abstract
The utility model discloses a spinneret plate hole for producing a sixteen-hole hollow fiber. The spinneret plate hole is composed of twelve H-shaped narrow gaps and one cross-shaped narrow gap, wherein the twelve H-shaped narrow gaps are radially and evenly distributed in a circumference mode with the cross-shaped narrow gap as the center, the top end of the cross-shaped narrow gap is rightly opposite to the top ends on the inner sides of the H-shaped narrow gaps, distance exists between the top end of the cross-shaped narrow gap and the top ends on the inner sides of the H-shaped narrow gaps, and radial distance exists among the H-shaped narrow gaps. The spinneret plate hole for producing the sixteen-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 sixteen-hole hollow fiber with good spinnability, wherein the sixteen-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 16 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 16 hole doughnuts, consisted of by 12 I shape slits and a cross slit, 12 described I shape slits are circumference centered by described cross slit radial uniform, and the medial roof of the top of described cross slit and described I shape slit is rectified to and is had spacing, has radial spacing between the described I shape slit.
The slit width of described I shape slit, described cross slit equates that all described width is between 0.04～0.3mm.
Spacing between the inboard top of the radial spacing between the described I shape slit, the top of described cross slit and described I shape slit all equates, 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 16 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
Accompanying drawing is the utility model structural front view.
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.
As shown in drawings, a kind of spinneret hole of production 16 hole doughnuts, consisted of by 12 I shape slits 1 and a cross slit 2, each I shape slit 1 internal communication, cross slit 2 internal communication, 12 I shape slits 1 are circumference centered by cross slit 2 radial uniform, and the medial roof of the top of cross slit 1 and I shape slit 2 is rectified to and had a spacing ε
