Abstract
ABSTRACT OF THE DISCLOSURE
The dilution factor plays a significant role in the aftertreatment of dyeings. According to the invention the dilution factor in rope-dyeing machines is raised and hence time and water is saved by moving the textile rope after the liquor or rinse bath has been discharged several times through the rope-dyeing machine by means of a gas or steam drive but without liquor. This gives good dewatering between the individual aftertreatment stages, and as a result a more favorable dilution effect on introducing the next liquor.

- 2 - HOE 83/F 106 The present invent;on relates to a process for aftertreat;ng ~oven or kn;~ted text;les ;n rope form w;th l;qu;d treatment agents.
It ;s common knowledge to aftertreat dyed textiles ~;th, for example, wash or clear;ng l;quors and ;s ;ncl;s-pensible in practise if, in particular~ wash- and rub-fast dye;ngs are to be achieved. The aftertreatment primarily involves rinsing out residual liquor, unfixed dyestuff portions, chemicals~ aux;l;aries and the like from the 10 preced;ng treatment stageO It is frequently advisable to follo~ this with a further aftertreatment, for example soften;ng, so that the product of the process can be opt;m;zed ;n terms of ;ts end-use properties~
Dye;ng on jet~dye;ng mach;nes at the short l;quor 15 ratio of 7:1 generally requ;res 12 aftertreatment baths ;nstead of the 6 at a l;quor ratio of 20.1. The effic;ency of every one of these customary aftertreatment operat;ons ;n terms of the completeness of removal of proport;ons of the orig;nal treatment agent left beh;nd in the 000ds 20 ;s cr;t;cally governed by the dilution factor achieved by the aftertreatment l;quor (r;nse l;quor) supplied to the dye;ng machine a In many rope-dyeing machines, in particular those ut;l;zing the jet-dye;ng pr;nciple, it is precisely this 25 fact which presents considerable problems, so that i~

treatment baths must be allowed for w;th the very same dyeing jet, especially ;n short liquor rat;os, than is the case ~ith, for example~ a dye beck. This necessitates apprec;able extra consumpt;on of t;me and valuable ~ater.
It is thus an object of the present invent;on to intens;fy the aftertreatment ;n rope-dyeing machines in order to reduce the number of aftertreatment baths required for a satisfactory dyeing result and hence to perm;t the sav;ng of t;me and water.
1 10 It has no~ been found that the object outlined ;n the preceding p3ragraph can be satisfactorily achieved and an improvement of the de~atering of the textile mate-rial bet~een the ;ndiv;dual aftertreatment stages can be put ;nto effect ;f, ;n the course of the measures for aftertreat;ng the textile rope~ use is made of the novel way of driv;ng endless goods ;n jet-dyeing mach;nes wh;ch was descr;bed ;n Published European Patent Appl;cation EP-A-0,014,919 and the rotat;on of the goods in rope form~
~h;ch ;s brought about and kept in mot;on by the k;net;c energy converted to the f;ber mater;al as the beam of the jet ;mpacts ;n the forward direct;on~ is not interrupted during the dropp;ng of, for example, the dyebath and the subsequent aftertreatment baths or dur;ng the ref;lling of the latter, but this drive is instead continued by solely c;rculating the liquor by means of a gas or steam flow, and the text;le rope ;s thus kept in motion virtually w;thout any participation by a liquid treatment medium.
In th;s way a high degree of de~atering ;s brou~ht about w;thout the goods com;ng to rest.

Claims (2)
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A process for raising the dilution factor in the after-treatment, as successive but separate stages on the same apparatus with a plurality of identical or different treatment liquids, of ropes of woven or knitted textile fabrics discontinuously circulating in endless form in jet piece-dyeing apparatus for the purpose of rinsing off residues of unabsorbed or unfixed treatment agents from a preceding textile-finishing wet-treatment operation by the exhaust method, the propelling force for transporting the textile material within the self-contained apparatus being provided hydraulically through the actuation of the jet system as long as liquid treatment agent is circulating in the same direction and then being maintained during the discharge of and refill with treatment liquid by means of a gas flow, comprising bringing about, by means of -the drive gas, more substantial dewatering of the textile rope between the individual after-treatment operations which may be different if desired, by allowing the textile material to circulate an additional number of cycles without any action of liquor after emptying the storage space of the dyeing jet from the treatment liquid and before the next aftertreatment liquor is fed in.
2. The process as claimed in claim 1, wherein the dewatering of the textile rope is assisted by mechanical measures utilizing the centrifugal forces arising in the transport of the goods or by drawing off the adhering water by means of a vacuum.
