Definitions
- the present invention relates toa novel and improved apparatus for producing or spinning artificial yarns at high spinning speeds.
- acid starvation means that theyarn filaments, just after they issue from the spinnerette, were not receiving sufficient amounts of fresh non-contaminated coagulating acid due to the high speed extrusion of the filaments.v This condition is particularly prevalent in the production of tire cord wherein large bundles of filaments are extruded. It is very important that fresh acid be supplied to the filaments at the point of extrusion since an initial and adequate hardening or coagulation of the filaments must occur at this point to withstand the ⁇ stretching and other physical forces appliedto the filaments immediately after the filaments are extruded.
- the coagulating bath should be made to flow rapidly in a path past the spinnerette facein a direction concurrent with that ⁇ of filament travel.
- the thought here was that fresh acid would be rapidly supplied across the spinnerette face.
- the filaments were spun into an elongated tube submerged in the coagulating bath and were drawn through the ⁇ tube by suitable godets.
- the acid bath flow within the bath was set upv so as to flow through the tube.
- lt is another object of our invention to provide a novel and improved tube spinning apparatus for forming yarns wherein an increased acid ow is effected across the face of the spinnerette and wherein a sufficient quantity of the acid with adequate flow is continuously supplied through the spinning tube whereby the filaments may be properly coagulated as they issue from the spinnerette and as they pass through the tube.
- Another object of the invention' is to provide a high speed tube spinning apparatus wherein a relatively quiescent area is provided in the acid ow over and adjacent the spinnerette face.
- Figure l is aside' view partially sectioned of our novel and improved tube spinning apparatus for forming artificial yarns.
- Figure 2 is a View taken along the lines lI-II of Figure l.
- our improved tube spinning apparatus comprises a container 1 which holds a quantity of a coagulating medium 3 such as a sulfuric acid of desired composition.
- the coagulating bath container 1 has suitable inlets and overflow units (not shown) whereby the level of the bath within the container may be held constant.
- the spinning solution from which the filaments 6, 6 are formed passes through v a conduit 8 which is pivotally mounted at a point outside of the container 1.
- One end of the conduit 8 fits within a terminal connector 11 which in turn is supported within a bracket 14 secured to a wall 17 of the container 1.
- a bolt 19 extends through one of the bracket arms and is tightened against the terminal connector 11. With this arrangement, the conduit 8 may be swung into and out of the Vcoagulating bath by manual manipulation.
- the filament-forming solution such as viscose
- the pipe 22 leads from a pump which receives the spinning solution from a filter unit connected with a main supply line for the spinning solution (none of these elements being shown).
- a spinnerette 25 is connected to the opposite end of conduit 8 through a coupling 27 and the conduit connector 2,9.
- the spinning solution passes through the Supply pipe 22, into the terminalv connector 11, through 3 i I t the conduit 8 aud finally through the spinnerette 25 fro which the shaped filaments issue.
- a duct memberl 31whercin the duet is preferably of funnel-shape.
- the tapered mouth portion 33 of the funnel-shaped duet lies within the interior of the container 1 while the stem portion 35 of the funnelshaped duct member lies .generally externally of the bath container 1.
- the smaller or second duet member 37 which may be termed a small tube is permanently affixed in position and held in place within the first member' 31 by the retaining ribs 39, 39 of the open ribbed member 40 ( Figure 2) affixed to the inner surface of the inner duct member 31.
- the ribs ⁇ 39, 39 extend between the inner surface of the tapered mouth portion ol ⁇ duct member 31 and the periphery of the second member 37.
- Guiding bosses 42, 42 are affixed to the ribs 39, 39 and serve the purpose of guiding the spinnerette directly into the mouth of the second or smaller duct member 37 when the spinnerette 25 and conduit 8 are swiveled into the coagulating bath to assume their lowermost position.
- a spinning tube 45 of larger diameter than the duet 37 is positioned Within the stern portion 35 of the funnelshaped conduit 31.
- a sealing ring 47 of suitable composition is provided in the indent 49 of the conduit 31 to prevent coagulating liquid from seeping out around the periphery of the tube 45.
- the conduit 8 and the spinnerette 25 secured thereto are lowered into the coagulating bath 3.
- the guiding bosses 42, 42 on the supporting ribs 39, 39 of ribbed member 40 guide the spinnerette into place directly within the mouth of the smaller or second duct member 37.
- Spinning solution lsuch as viscose
- the spinning solution passes through the spinnerette 25 to form the filaments 6, 6.
- the filaments then pass into and through the second or smaller duct 37.
- the flow of the medium over the face of the spinnerette and through the duct 37 is substantially and effectively stepped up or increased because of the combined features of the small degree of clearance between the spinnerette periphery and the inner wall of the duct 37 and the small diameter of the duet adjacent its discharge end.
- This flow ratio may be varied as desired by changing the clearance and the diameter of the duet 37 at its discharge end.
- acid also flows from the container 1 around the ribs 39, 39 and into and through the annular channel 55 formed between the periphery of the small duct 37 and the inner wall of the tapered mouth portion 33 of the funnel-shaped duet member 31.
- the acid entering the channel 55 ows over the periphery of the smaller duct member 37 and is combined with the acid emerging from the discharge end of the smaller duet 37.
- An acid rate of fiow similar to that set up within the duct member 37 is set up within the channel 55.
- the filaments leavethe tube 45, they are further processed and collected in or on a suitable collecting unit.
- Apparatus for spinning filaments by the wet-spinning process comprising a coagulating bath container, a supply conduit for the spinning solution which conduit is pivotally mounted externally of the coagulating bath container whereby the conduit is swingable into and out of the container, a spinnerette secured to the free end of the conduit, afirst duet member extending through one wall of the container, a smaller duct member of shorter length and of smaller diameter than the tirst duct member positioned concentrically within and terminating at a point along the length of the first duet but prior to the discharge end of the first duet member whereby a channel is formed between the inner wall of the first duct member and the periphery of the smaller duet member, the mouth of said smaller duet being of slightly larger diameter than that of the spinneret for receiving the spinnerette when the spinnerette and its supporting conduit are swung into their lowermost position within the bath, means extending from the first duet member for supporting the smaller duet in place, and a spinning tube of larger diameter
