Definitions
- the solution or pigment suspension is pumped into the spinning solution feed pipe, carefully calibrated gear pumps serving to meter the flow.
- gear pumps serving to meter the flow.
- a viscose spinning solution is supplied through a pipeline 1 to a spinning machine 2 via a mixer l2.-
- the pipe 1 has a shunt or bypass 3 through which part of the spinning solution flows.
- two gear pumps 4 and 5 which are interconnected in series by a tube 6.
- a supply pipe 7, serving to supply a dyestuff solution or pigment suspension from a reservoir 8 discharges into the tube 6.
- a filter 9 is inserted in the pipe 7 and, associated with the filter, are valves 10 and 11.
- the pipe 7 is in open connection with the reservoir 8 for the low viscosity additive.
- the shunt pipe 3 and the main viscose pipeline 1 discharges into the mixer 12, and from the mixer 12 the mixture goes to the spinning machine 2.
- the particular mixer used at 12 forms no part of the present invention and any known mixer may be used.
- the pump 4 is operated to deliver less than the pump 5 so that a suction exists in conduit 6 whereby the solution from conduit 7 is drawn into the spinning solution.
- Example A viscose spinning solution was supplied under pressure from a reservoir, not shown, through the pipe 1, and in the shunt 3 the pump 4 was adjusted to deliver 144 cm. /min., which amounted to about A; part of the amount in the main pipe 1.
- the present invention involves dividing the flow of spinning solution into two paths and then sucking the additive into the flow in one of those paths in such a way that no pump in the system is required to handle the additive alone. Because the two pumps in the viscose line work in tandem and because both of them are handling viscose solution, the wear effects of additives such as titanium oxide suspensions are almost completely mitigated. With the method according to the present invention not only is the wear greatly reduced but the metering of the dye solution or pigment suspension can be maintained within a range of about 1%.
- a process for dispersing a coloring material uniformly throughout a viscose spinning solution which comprises supplying a viscose solution to an input zone, dividing the flow of solution and passing the major portion directly to a principal mixing zone, by-passing the minor portion and propelling the same to a color suspension adit zone while supplying a'constant amount of a color suspension to said adit zone wherein the minor portion is premixed with the suspension in substantially the same concentration, positively withdrawing the mixture from the adit zone at a higher rate than the minor portion is propelled thereto prior to entry in the adit zone to induce flow of the suspension and finally passing the mixture to said principal mixing zone into which the major portion is being discharged.

- a method for adding a predetermined proportion of a pigment dispersion automatically and continuously to a stream of viscose spinning solution comprising passing the main stream of viscose into a blending zone be fore it enters the spinnerets, diverting a minor portion of the viscose stream through a shunt line having a pair pump so that the amount of additive is equal to the 5 difference in capacity between the two pumps.
